Government Interventions in Brazilian Bank Lending: Do Public and Private Banks Compete?* * The opinions expressed herein are those of the authors and not necessarily those of the Banco Central do Brasil (Central Bank of Brazil). 2 ABSTRACT This paper investigates the existence of competition between retail government-owned and private banks in the Brazilian bank lending market. We exploit an exogenous shock to the lending market, which made governmental banks raise the credit supply combined with a decrease in the interest rates charged on loans. Our Diff-in-Diff model predicts that public banks show higher loan growth, non-performing loans, lending returns, operational returns and cost of funding compared to private peers after the event. In addition, we find evidence of differences in the asset allocation decisions of banks, as private banks preferred an asset portfolio with a higher proportion of liquid assets holdings and less loans compared to public banks after the event. These findings suggest that government-owned retail banks do not compete with private peers when their objective function is not only to maximize profits given risk. Keywords: Brazilian bank lending market, federal government interventions, public banks, private banks, loan annual growth. 3 1. Introduction Since the international financial crisis in 2007/2008, the academic debate relative to the role of state-owned banks and their implications for the financial intermediation has been intensified. In particular, several empirical studies of recent literature emphasize the stabilizing role played by public banks in the credit supply provided to the productive sector in periods of financial crisis and economic recession. Public banks are able to maintain higher rates of loan growth in times of crisis in comparison with their private peers, which reduce their loan supply and increase liquidity holdings (Allen et al. 2013; Bertay et al., 2015; Brei and Schclarek 2015; Cull and Martinez–Peria, 2013; De Haas et al., 2012; Micco and Panizza 2006). Similar results are reached by Oliveira et al. (2014) and Coleman and Feler (2014) who find evidence that government-owned banks in Brazil rose credit growth rates, offsetting declines in lending by private banks during the 2008 financial crisis. In contrast, the political view, which is another strand of the banking literature, reveals a less benign perception of the state presence in the banking sector and in the real economy. For a long period of financial liberalization, started in 1970, a view favorable to the privatization of the banking sector prevailed. Several empirical papers argued that the presence of the state in the banking sector generates distortion on the allocation of resources because the credit decision is politically motivated. State banks tend to increase their lending to companies that are political supporters of the politicians, particularly during the electoral cycle. As a consequence of this misallocation, greater government participation in bank ownership tends to be associated with lower levels of financial development and slower economic growth (Barth et al. 2001 and 2004; Dinç, 2015; La Porta et al., 2002; Micco et al., 2007; Sapienza, 2004). Other negative factor posited by this particular strand of the banking literature relates to the financial instability. Caprio and Martinez-Peria (2002), demonstrate that greater state presence in the banking system in the beginning of 1980 tends to be associated with higher probability of banking crisis during 1980-1997. Detailed individual country studies, with purely Brazilian data, provide consistence evidence that corroborates this less benign role of public banks in the financial system and in the real economy (Carvalho, 2014; Claessens et al. 2008). Other facet of the literature investigates the effect of public banks’ presence on the banking competition. Coelho et al. (2013) examine the competitive effect by determining how the conduct of private banks is affected by the entry of a public bank. The results suggest that the 4 presence of a rival private bank toughens competition, but the presence of a public bank does not affect the conduct of private banks. We investigate whether retail private banks compete with state banks in the loan market. We exploit an event occurred in August of 2011, when the federal Brazilian government adopted several interventions in the bank lending market through public banks to boost credit supply growth and decrease the loan rates. Our empirical strategy relies on the double difference model, in which we analyze the differential effect of the government interventions on annual bank loan growth, non-performing loans, lending returns, operational results, cost of funding, as well as, differences in the asset allocation decisions of public banks (treatment group) in comparison with private banks (control group). The results show that public banks have higher loan growth, loan quality, lending returns, operational returns and cost of funding compared to private peers after the treatment. In addition, we find evidence of differences in the asset allocation decisions of banks, as private banks preferred an asset portfolio with a higher proportion of liquid assets holdings and less loans compared to public banks after the treatment. These findings suggest that governmentowned retail banks do not compete with private peers when their objective function is not only to maximize profits given risk. Our primary contribution to the banking empirical literature is to investigate the existence of competition between public and private banks in the event of government interventions, which impact directly solely one group, the public banks. Additionally, our analysis differentiates from the previous studies because we observe the differential effect of government interventions not only on bank performance, but also on changes in the asset allocation decisions. This article is organized as follows: Section 2 provides the description of the Brazilian bank lending; Section 3 contains the empirical strategy; Section 4 describes the data and presents some summary statistics; Section 5 discusses the results; and Section 6 reveals the conclusions. 5 2. The Brazilian Bank Lending Structure The Brazilian bank lending has been growing in a fast pace in recent years. Total bank lending to GDP has risen significantly from 28.9 % of GDP in 2007 to 47.1 % GDP in 2014. According to Central Bank of Brazil, the bank credit market in Brazil presents a moderate concentration level, in which the six leading commercial banks account for, approximately, 80.2% of the total Brazilian banking system in 2014. Meanwhile, the two largest federal public banks (Banco do Brazil and Caixa Econômica Federal) stand for about 45.1% of the overall Brazilian banking system in 2014. A structural transformation has helped raise the Brazilian bank lending, which contemplates the capital inflows providing liquidity to banks; the development of the domestic capital market, and the economic stability of the country benefited from the significant increase in commodity prices and improvements on domestic macroeconomic conditions. It is important to highlight that this prominent scenario presented some changes with the rise of the international financial crisis in 2008-2009. Particularly, with the Lehman Brothers’ bankruptcy in mid-September 2008, the domestic economic activity showed deterioration, requiring further adjustments on government policies. Therefore, in response to the decline in economic activity, the federal government implemented an expansionist credit policy among with a looser macroeconomic policy in 2009. In this sense, the two largest federal government-owned banks (Banco do Brazil and Caixa Econômica Federal) played an active countercyclical role compensating for the retrenchment by private lenders during the global financial crisis. In 2010, economic activity recovered faster and more strongly than expected, with Gross Domestic Product (GDP) growing at a fast pace of 7.5%. For this reason, starting in mid-2010 until mid-2011, a range of macroprudential tools target on consumer credit were implemented by Central Bank of Brazil to address financial stability concerns related to the rapid pace of credit expansion and, consequently, the increment in the non-performing loans rates. Since mid-2010 up to mid-2011, in response to the rapid increase of consumer loans, the government has tightened macroprudential measures in some specific lending products. In December of 2010, the Central Bank of Brazil announced an increase of the minimum payment for credit card bills to 15% (previously 10%); anticipated another hike to 20% by December of 2011; and announced a rise of capital requirements for long term consumer loans (the risk weight for such exposures rose from 100% to 150%). In April of 2011, the Tax on Financial Operations (IOF) on consumer credit operations was expanded to 3% (previously 1.5%). 6 After strong growth in 2010, the Brazilian economy has persisted slowed down in 2011. In response to the economic downturn, starting in the second half of 2011, the Central Bank of Brazil relaxed the macroprudential measures among with a new monetary easing cycle by cutting the basic reference interest rate (SELIC) to its historical minimal level of 7.25%, in October of 2012. Both actions aimed to induce economic activity through higher credit expansion, especially, through the hike of public banks’ lending supply. These macroprudential policies include: (a) reducing the risk weights on vehicle and personal loans; (b) increasing the fraction of reserve requirements on time deposits that can be met by extending loans or purchasing loan portfolios from other banks; (c) allowing banks to use part of their reserve requirements to increase working capital loans; (d) maintaining the minimum payment for credit card bills at 15% (previously programmed to be increased to 20% in December of 2011); (e) reducing IOF tax on credit for consumption (from 3% to 2.5%). Additionally, in order to transmit the SELIC reduction to the loan interest rates charged by the banks to the borrowers, in April of 2012 the federal government launched a campaign aiming to reduce the banks’ spread levels, which were led by the state-owned banks. In particular, headed by the largest commercial bank (Banco do Brasil) and the largest savings and loan institution (Caixa Econômica Federal). The campaign focused mainly on the retail credit segment. In favor of enabling the federal government strategy of boosting credit supply growth through public banks combined with diminished loan rates, the Brazilian National Treasury made several capital injections, which includes BRL 8.1 billion to Banco do Brasil and BRL 13 billion to Caixa Econômica Federal, both in September of 2012. In a nutshell, the federal government interventions in the Brazilian bank lending, started in the second half of 2011, are the following: Expanded bank credit through the hike of public banks’ lending supply; New monetary easing cycle by cutting the basic reference interest rate; Launched a campaign aiming to reduce the banks’ spread levels led by stateowned banks; Brazilian National Treasury made several capital injections in public banks; Central Bank of Brazil relaxed the macroprudential measures. Taking into consideration these federal Brazilian government interventions, a structural break in the lending growth rate by ownership type occurred in August of 2011, resulting in the public banks regaining the market share leadership in terms of loan growth; meanwhile, the private banks responded with a heterogeneous lending behavior by diminishing the loan growth rate pace. 7 In chart 1 it is possible to visualize the heterogeneous lending behavior according to ownership type, as well as, the structural break occurred in August of 2011. [INSERT CHART 1 HERE] 8 3. Empirical Strategy Our empirical methodology relies on the use of double difference model to evaluate the differential effect, public banks vs. private banks, of the government interventions on the following variables: a) annual loan growth pace in nominal and real terms; non-performing loans; c) lending return; d) operational return; e) securities’ revenue participation; f) cost of funding. The state-owned banks are defined as the treatment group because they were directly affected by the government interventions, and the private banks are classified as control group. In order to better reflect the Brazilian bank lending market we did not treat all observations equally in the regressions, as some banks are more informative than others. For this reason, we weighted the observations differently by using the natural logarithm of total loans of each bank. The estimates were conducted by using robust standard errors in order to avoid heteroscedasticity. Also we adjusted the standard errors to account for within group correlation by reporting clustered standard errors at bank-level, totaling 17 clusters. If we had assumed that an observation of a given bank were independent of all other observations for the same bank in the data set, the standard errors produced would be underestimated and the statistical significance would be overstated. Some empirical studies highlight that the decision to use clustered-robust standard errors should be based on the number of clusters. If the number of clusters is small, there is no guarantee that the cluster-robust estimator will improve inference in relation to OLS standard errors estimators. In particular, Rogers (1993) indicates that clustered- robust standard errors with 20 or less balanced clusters would suffer from an upward bias. In respect of the number of clusters, the study of Nichols et al. (2010) highlights the following statement: “If the number of clusters is small, this will substantially increase the critical values relative to those computed from the standard Normal (t with large degrees of freedom)”. Regarding that our data contain 17 balanced clusters, our clustered- robust standard errors estimates may suffer from an upward bias leading to extremely conservative results. 9 Effect on Annual Loan Growth Pace To investigate if the increase in public banks’ credit supply diminishes the annual loan growth pace of the private banks, we estimate the following equation: Li,t 1 Publici,t 2 After _ August 2011t 3 Publici,t After _ August 2011t Sizei, June2011 GDPt i,t (1) where Δ Li,t denotes the annual loan growth of bank i in time t; Public i,t is a dummy variable obtaining a value 1 if public bank, and 0 if private; After_August 2011t is a dummy variable obtaining a value 1 if after August 2011 and o for the remainder periods; (Publici,t ×After_August 2011t) is the interaction term that assumes a value 1 if public bank and after August 2011. Size and GDP are controlled variables that capture the specific characteristic of the bank and the macroeconomic trends, respectively. Finally εi,t are the clustered - robust standard errors. The β1 coefficient measures the difference between the average annual loan growth rate of public banks and private banks for the whole sample period; the β2 coefficient measures the difference between the average annual loan growth rate of all banks for the period before and after the treatment (August 2011). Finally, the β3 coefficient consists of the Diff-in-Diff estimator, our main parameter of interest, which captures the effect of the government interventions on the annual loan growth rate of public banks in comparison with private banks. Effect on Non-performing Loans A large literature argues that banks reduce their lending standards and become riskier during periods of excessive lending growth. Therefore, it indicates that higher rates of bank loan growth are associated with greater risk-taking, leading to elevated non-performing loans. Since public banks exhibited significantly higher rates of loan growth than their private competitors, they may have lowered their lending standards and collateral requirements in order to boost credit demand. To analyze if the rise in public banks’ credit supply deteriorated the non-performing loans of the private banks, we estimate the following equation: 10 NPLi,t 1 Publici,t 2 After _ August 2011t 3 Publici,t After _ August 2011t Sizei, June2011 GDPt i,t (2) where Δ NPLi,t denotes the non-performing loans of bank i in time t; Publici,t is a dummy variable obtaining a value 1 if public bank, and 0 if private; After_August 2011t is a dummy variable obtaining a value 1 if after August 2011 and o for the remainder periods; (Publici,t ×After_August 2011t) is the interaction term that assumes a value 1 if public bank and after August 2011. Size and GDP are controlled variables that capture the specific characteristic of the bank and the macroeconomic trends, respectively. Finally εi,t are the clustered - robust standard errors. The β1 coefficient measures the difference between the average non-performing loans of public banks and private banks for the whole sample period; the β2 coefficient measures the difference between the average non-performing loans of all banks for the period before and after the treatment (August 2011). Finally, the β3 coefficient consists of the Diff-in-Diff estimator, our main parameter of interest, which captures the effect of the government interventions on the non-performing loans of public banks compared to private banks. Effects on Lending Return Credit growth, non-performing loans and loan rate are important determinants of lending return. In this sense, existing studies suggest that non-performing loans negatively influence the bank’s lending return, while loan rate shows a positive association. Taking into consideration that public banks reported significantly higher rates of lending growth, and also decreased interest rates charged on loans in comparison to their private competitors, those actions may have negatively impacted their credit portfolio return. To investigate if the increase in public banks’ credit supply diminished the lending return of the private banks, we estimate the following equation: Lreturni,t 1 Publici,t 2 After _ August 2011t 3 Publici,t After _ August 2011t Sizei, June2011 GDPt i,t (3) 11 where ΔLreturni,t denotes the lending return of bank i in time t; Publici,t is a dummy variable obtaining a value 1 if public bank, and 0 if private; After_August 2011t is a dummy variable obtaining a value 1 if after August 2011 and o for the remainder periods; (Publici,t ×After_August 2011t) is the interaction term that assumes a value 1 if public bank and after August 2011. Size and GDP are controlled variables that capture the specific characteristic of the bank and the macroeconomic trends, respectively. Finally εi,t are the clustered - robust standard errors. The β1 coefficient measures the difference between the average lending return of public banks and private banks for the whole sample period; the β2 coefficient measures the difference between the average lending return of all banks for the period before and after the treatment (August 2011). Finally, the β3 coefficient consists of the Diff-in-Diff estimator, our main parameter of interest, which captures the effect of the government interventions on the lending return of public banks in comparison with private banks. Effect on Operational Return Economic theory does not uniquely predict the sign of the relationship between operational return and loan growth rate because the association can stem from several reasons. Higher loan growth can be negatively associated with bank operational return, if banks relax their underwriting standards in order to achieve higher credit growth, contributing to elevated non-performing loans. In contrast, higher loan growth may have a positive impact on operational return if banks expand into lower margin lending businesses without taking on higher-risk loans. Another reason for the differential impact on operational return of public banks in comparison with private peers relies on the private banks heterogeneous behavior as they shifted from credit supply to invest in safer assets (i.e. securities) that may result in smaller operational return due to the positive risk-return association. To investigate if the increase in public banks’ credit supply decreased the operational return of the private banks, we estimate the following equation: ROAi,t 1 Publici,t 2 After _ August 2011t 3 Publici,t After _ August 2011t Sizei, June2011 SELIC t i,t (4) 12 where ΔROAi,t denotes the operational return of bank i in time t; Publici,t is a dummy variable obtaining a value 1 if public bank, and 0 if private; After_August 2011t is a dummy variable obtaining a value 1 if after August 2011 and o for the remainder periods; (Publici,t ×After_August 2011t) is the interaction term that assumes a value 1 if public bank and after August 2011. Size and GDP are controlled variables that capture the specific characteristic of the bank and the macroeconomic trends, respectively. Finally εi,t are the clustered - robust standard errors. The β1 coefficient measures the difference between the average operational return of public banks and private banks for the whole sample period; the β2 coefficient measures the difference between the average operational return of all banks for the period before and after the treatment (August 2011). Finally, the β3 coefficient consists of the Diff-in-Diff estimator, our main parameter of interest, which captures the effect of the government interventions on the operational return of public banks compared to private banks. Effect on Securities’ Revenues Participation A large literature emphasizes that public banks are able to maintain higher rates of loan growth in times of financial crisis and economic adversities in comparison with their private peers, which reduce their loan supply and increase liquidity holdings in response to a rise in risk aversion. To investigate if the increase in public banks’ credit supply leaded to an investment reallocation for the private banks from loans to securities, we estimate the following equation: Participationi,t 1 Publici,t 2 After _ August 2011t 3 Publici,t After _ August 2011t Sizei, June2011 SELIC t i,t (5) where ΔParticipationi,t denotes the securities’ revenues participation of bank i in time t; Publici,t is a dummy variable obtaining a value 1 if public bank, and 0 if private; After_August 2011t is a dummy variable obtaining a value 1 if after August 2011 and o for the remainder periods; (Publici,t ×After_August 2011t) is the interaction term that assumes a value 1 if public bank and after August 2011. Size and GDP are controlled variables that capture the specific characteristic of the bank and the macroeconomic trends, respectively. Finally ε i,t are the clustered - robust standard errors. 13 The β1 coefficient measures the difference between the average securities’ revenues participation of public banks and private banks for the whole sample period; the β2 coefficient measures the difference between the average securities’ revenues participation of all banks for the period before and after the treatment (August 2011). Finally, the β3 coefficient consists of the Diff-in-Diff estimator, our main parameter of interest, which captures the effect of the government interventions on the securities’ revenues participation of public banks in comparison with private banks. Effect on Cost of Funding The excessive public banks loan growth rate may have generated a demand for additional capital in order to support their lending expansion, rising their funding costs. Consequently, this action may have increased the funding competition between public and private banks, elevating the private banks’ cost of liabilities. To analyze if the increase in public banks’ credit supply increased the private banks’ cost of funding, we estimate the following equation: Cost i,t 1 Publici,t 2 After _ August 2011t 3 Publici,t After _ August 2011t Controls i, June2011 i,t (6) where ΔCosti,t denotes the cost of funding of bank i in time t; Publici,t is a dummy variable obtaining a value 1 if public bank, and 0 if private; After_August 2011t is a dummy variable obtaining a value 1 if after August 2011 and o for the remainder periods; (Publici,t ×After_August 2011t) is the interaction term that assumes a value 1 if public bank and after August 2011. Controls i,June 2011 are control variables to capture the specific characteristic of the bank. Finally εi,t are the clustered - robust standard errors. The β1 coefficient measures the difference between the average cost of funding of public banks and private banks for the whole sample period; the β2 coefficient measures the difference between the average cost of funding of all banks for the period before and after the treatment (August 2011). Finally, the β3 coefficient consists of the Diff-in-Diff estimator, our main parameter of interest, which captures the effect of the government interventions on the cost of funding of public banks in comparison with private banks. 14 4. Data Description The empirical analysis is based on a sample of 17 commercial banks focusing on the retail credit segment, in which 9 are public banks and 8 are private banks, for the period 2009– 2014 in a quarterly frequency, totaling 408 observations. The time period chosen contemplates the federal government interventions in the Brazilian bank lending market by directly interfering in the public banks. In terms of data set for the commercial banks, we selected the top 50 banks in Brazil, classified by loans and leases in the data-base June 2011. In addition, we excluded development banks, cooperatives, manufacturers’ banks and banking institutions that operate in a niche credit market, such as “middle market loan” and “corporate loan”. It is worth highlighting that commercial private banks show a heterogeneous lending behavior because they operate in distinct loan segments, such as retail, middle market and corporate. The ideal data-set should have contained, besides the commercial public banks, all the commercial private banks. In this empirical framework, we should have included in the model a control variable for type of loans to address the heterogeneity behavior concern. However, this approach was not feasible because the loan-level data is private information registered at the Credit Information System of the Central Bank of Brazil (SCR), and we could not obtain from this source. Given this loan-level data restriction, as a solution we selected commercial private banks with a more homogeneous behavior in the credit market, focused on the retail segment as this loan segment had been more directly affected by the government interventions. The resulting sample of 17 banks responds for 90.55% of the total loan provided by commercial banks, as of June 2011. In order to classify according to type of ownership, we used the Central Bank of Brazil definition, which considers as state-owned banks if more than 50% of controlled stake belongs to the state or federal government, the remainder of the institutions were defined as private banks. There is no time variation in ownership for the financial institutions in our sample period. Our source of bank-level data is the Central Bank of Brazil, specifically collected from IF.Data (Selected Information on Supervised Institutions). These bank-level data have a quarterly frequency that coincides with the released data for financial reports which are June, September and December of each year. 15 The macroeconomic control variables were taken from the Time Series Management System (SGS) of Central Bank of Brazil (BCB) and from the Geography and Statistics Brazilian Institute (IBGE). Table 1 contains definitions of all the variables included in our empirical analysis and the respectively sources. It is worth highlighting that we adopted a similar methodological approach to the work of Delis et al. (2014). We conducted estimations controlling for size, which is calculated as the natural logarithm of total assets as of June 2011 for the whole data-set period, in order to obtain an unbiased diff- in-diff estimators. In the cost of funding estimations, particularly for the bank characteristics’ control variables added to model, we adopted a similar methodological approach to the work of Barros et al. (2015). The bank specific controls for the whole data-set period were calculated at preevent levels, as of June 2011. [INSERT TABLE 1 HERE] Table 2 reports the descriptive statistics for the variables employed by ownership type, as well as, before and after the structural break. Interestingly, it is possible to observe that public banks and private peers have a different lending behavior by analyzing the variables’ mean previously and after the structural break. This pattern is consistent with our finding, which shows that public banks expanded the loan supply; meanwhile, the private peers diminished the loan growth rate pace in response to the federal government interventions. The variable size shows significantly distinguished mean values according to the ownership type, mainly this is due to the presence of estate-owned banks in the sample, which are significantly smaller in comparison with the two major players (Banco do Brasil and Caixa Econômica Federal) and to the private banks contemplated in the analysis. [INSERT TABLE 2 HERE] 16 5. Results Effect on Annual Loan Growth Pace Table 3 reports the results of Equation 1, which measures the effect of government interventions on the annual loan growth pace, in nominal and real terms. Even though the β1 coefficients (reported in Columns I and V) are not statistically significant at usual level, the commercial public banks show in average annual loan growth, in nominal and real terms, smaller than the reported by the private banks. This finding is, essentially, influenced by two factors: the public banks’ counter-cyclical active role played in 2009 and the macro-prudential tools implemented in the credit market by the Central Bank of Brazil in 2010. After August 2011 (results reported in Columns I and V), all banks show in average a decrease in the annual loan growth pace, in nominal and real terms, and the β2 coefficients are negative and statistically significant at 10% level. This finding was determined, essentially, by the private banks’ lending behavior as they slowed their loan growth after the government interventions in the credit market through the public banks. In Column I the Diff-in-Diff estimator of our baseline specification is economically large, corresponding to a predicted 11.7 percentage points more nominal growth in loans of public banks compared to private banks after the event. The inference based on real terms (shown in Column V) is also economically large, indicating an increase of approximately 11.0 percentage points in loan growth of public banks in comparison with private banks after August 2011. For both regressions our coefficient of interest (Public × After August 2011) is statistically significant at 10% level. Recall that our clustered- robust standard errors may suffer from an upward bias. Even when we apply this extremely conservative procedure, our coefficients of interest for both regressions remain statistically significant. Additionally, we re-conducted estimates for our baseline specification using nonweighted observations. The results reported in Columns II and VI slightly changes the magnitude of our coefficients of interest (Public × After August 2011), but do not significantly alter our inferences. In Columns III and VII, when we control for GDP, the Diff-in-Diff coefficient for both regressions remains unchanged. Also the inclusion of GDP and Size as additional controls (Columns IV and VIII) do not alter the Diff-in-Diff coefficients obtained in our baseline specification. 17 Using quarterly time dummies, instead of GDP as macroeconomic control variable, we reestimated Equation 1. The Diff-in-Diff estimators remain essentially the same not only in terms of econometric significance, but also in terms of economic magnitude (results not reported here due to space considerations but available on request). Further estimations for Equation 1 are carried out with non-clustered robust standard errors; the Diff-in-Diff coefficients obtained in all regressions are significantly higher in terms of econometric significance (results reported in the Appendix). [INSERT TABLE 3 HERE] In a nutshell, after August 2011, the banking institutions according to ownership type showed a different lending behavior, in which the public banks led the credit supply expansion, meanwhile the private peers lent at a slower growth rate. It is possible to observe a change in private banks’ lending policies as they became gradually more selective in the loan supply after August 2011. This result might be explained by changes in the banks’ perception of risk due to deterioration in the Brazilian economic scenario with reflections in the non-performing loans rate of the private banks. In addition, the public banks reduced more sharply the loan interest rates charged to borrowers compared to the private peers, which allowed the increase in credit demand and the rise of the portability mechanism. Note that the Central Bank of Brazil allows borrowers to transfer outstanding loans between banks, the so-called portability mechanism; usually the decision is based on loan interest rates. The control variable, size, is not determinant to the annual growth loan rate. Regarding the controlled variable related to macroeconomic trends (GDP), we found a positive statistical significance at 10% level under the real terms procedure. Effect on Non-performing Loans Table 4 reports the results of Equation 2, which measures the effect of government interventions on the non-performing loans. In Column I the β1 (Public) and β2 (After August 2011) coefficients of our baseline specification are not statistically significant at conventional level. Our Diff-in-Diff estimator (reported in Column I), although weak, suggests that the nonperforming loans was higher for government-owned banks compared to private banks after the 18 government interventions. Note that our clustered- robust standard errors may suffer from an upward bias, leading to extremely conservative results. In addition, we re-conducted estimates for our baseline specification using non-weighted observations. The result reported in Columns II does not change the magnitude of our coefficient of interest (Public × After August 2011). In Column III, when we control for GDP, the Diff-in-Diff coefficient remains unchanged. Also the inclusion of GDP and Size as additional controls (Columns IV) does not alter the Diff-inDiff coefficient obtained in our baseline specification. Using quarterly time dummies, instead of GDP as macroeconomic control variable, we reestimated Equation 2. The coefficient of interest (Public × After August 2011) remains essentially the same not only in terms of econometric significance, but also in terms of economic magnitude (results not reported here due to space considerations but available on request). Further estimations for Equation 2 are carried out with non-clustered robust standard errors; the Diff-in-Diff coefficients obtained in all regressions are significantly higher in terms of econometric significance (results reported in the Appendix). [INSERT TABLE 4 HERE] These findings suggest that the significant public banks’ lending expansion after the government interventions did not lead to signs of deterioration in their loan portfolio compared to private banks. A combination of factors helps explain why the expansionist lending behavior of public banks reflected positively in their non-performing loans. Firstly, loans’ interest rates reduction encouraged by public banks was a crucial determinant for the increase in the portability mechanism. As the public banks reduce more sharply the loan interest rates charged to the borrowers, borrowers’ outstanding loans from private banks were significantly transferred to them. Specially, outstanding loans categorized as low credit risk, such as, real-estate loans and payroll-linked loans. Secondly, after August 2011, the composition of public banks’ loan portfolio reported a significant expansion in loans categories with less credit risk. For instance, rural loans, realestate loans and Payroll-deducted lending. On the other hand, the private banks lend out at a slower pace than public banks increased their loans’ maturity. This factor justifies, in parts, the higher loan loss provisions of private banks in comparison to public banks. 19 The control variable, size, is an important determinant to the non-performing loans, as reports a negative coefficient with statistical significance at 5% level. Regarding the controlled variable related to macroeconomic trends (GDP), we found a positive statistical significance at 1% level. Effect on Lending Return Table 5 reports the results of Equation 3, which measures the effect of government interventions on lending return. In Column I β1 coefficient of our baseline specification is negative and statistically significant at 5% level, given that public banks report in average smaller lending returns compared to private banks. This finding is, essentially, influenced by the public banks’ countercyclical active role played in 2009 and their reduction in the lending growth pace in 2010. After August 2011 (result reported in Column I), the whole banks’ sample show in average a decrease in lending returns as β2 coefficient presents negative statistical significance at 1% level. This result was determined, essentially, by the private banks’ lending behavior as they slowed loan growth after the government interventions in the credit market through the public banks. In Column I the Diff-in-Diff estimator of our baseline specification, although weak (pvalue of 0.112), indicates that the public banks’ lending returns were higher compared to private banks after the event (predicting approximately 1.5 percentage point additional increase in lending returns for public banks after August 2011). Note that our clustered- robust standard errors may suffer from an upward bias, leading to extremely conservative results. In addition, we re-conducted estimates for our baseline specification using non-weighted observations. The result reported in Columns II does not change the magnitude of our coefficient of interest (Public × After August 2011). In Column III, when we control for GDP, the Diff-in-Diff coefficient remains unchanged. Also the inclusion of GDP and Size as additional controls (Columns IV) does not alter the Diff-inDiff coefficient obtained in our baseline specification. Using quarterly time dummies, instead of GDP as macroeconomic control variable, we reestimated Equation 3. The coefficient of interest (Public × After August 2011) remains essentially the same not only in terms of econometric significance, but also in terms of economic magnitude (results not reported here due to space considerations but available on request). 20 Further estimations for Equation 3 are carried out with non-clustered robust standard errors; the Diff-in-Diff coefficients obtained in all regressions are significantly higher in terms of econometric significance (results reported in the Appendix). [INSERT TABLE 5 HERE] Even though the public banks reported differential at loan pricing in comparison with private peers, their lending returns were supported by their higher loan growth pace after the treatment. The control variable, size, is determinant to the lending return by reporting a negative statistical significance at 5% level. Regarding the controlled variable related to macroeconomic trends (GDP), we found a negative statistical significance at 1% level. Effect on Operational Return Table 6 reports the results of Equation 4, which measures the effect of government interventions on operational return. Even though the β1 coefficient (reported in Column I) is not statistically significant at usual level, the commercial public banks show in average operational return smaller than the reported by the private banks. This finding is, essentially, influenced by the public banks’ counter-cyclical active role played in 2009 and their reduction in the lending growth pace in 2010. After August 2011 (documented in Column I), the whole banks’ sample show in average a decrease in operational returns as β2 coefficient presents negative statistical significance at 1% level. This result was determined, essentially, by the private banks’ lending behavior as they slowed loan growth after the government interventions in the credit market through the public banks, and their higher loan loss provisions. In Column I the Diff-in-Diff estimator of our baseline specification is economically large, corresponding to a predicted 0.6 percentage point additional increase in operational return for public banks after August 2011. Also this coefficient of interest is statistically significant at 5% level. Recall that our clustered- robust standard errors may suffer from an upward bias. Even when we apply this extremely conservative procedure, our coefficient of interest remains statistically significant. 21 Additionally, we re-conducted estimates for our baseline specification using nonweighted observations. The result reported in Columns II slightly changes the magnitude of our coefficient of interest (Public × After August 2011), but does not significantly alter our inference. In Column III, when we control for SELIC, the Diff-in-Diff coefficient remains unchanged. Also the inclusion of SELIC and Size as additional controls (Columns IV) do not alter the Diff-inDiff coefficient obtained in our baseline specification. Using quarterly time dummies, instead of SELIC as macroeconomic control variable, we re-estimated Equation 4. The Diff-in-Diff estimators remain essentially the same not only in terms of econometric significance, but also in terms of economic magnitude (results not reported here due to space considerations but available on request). Further estimations for Equation 4 are carried out with non-clustered robust standard errors; the Diff-in-Diff coefficients obtained in all regressions are significantly higher in terms of econometric significance (results reported in the Appendix). [INSERT TABLE 6 HERE] As an implication of changes in the asset allocation of private banks, it appears that the revenues from securities did not offset the decrease in loans’ revenues of private banks. These findings could be explained by the risk-return trade-off. The control variable, size, is determinant to the operational return by reporting a negative statistical significance at the 10% level. Regarding the controlled variable related to macroeconomic trends (SELIC), we found a negative statistical significance at the 10% level. Effect on Securities’ Revenues Participation Table 7 reports the results of Equation 5, which measures the effect of government interventions on securities’ revenues participation. In Column I the β1 (Public) and β2 (After August 2011) coefficients of our baseline specification are not statistically significant at conventional level. Our Diff-in-Diff estimator (reported in Column I), although weak (p-value of 0.156), indicates that the Brazilian government interventions in the credit market directly through public banks determined a negative differential effect on the securities’ revenues participation of public banks in comparison to commercial private peers (predicting approximately 3.6 22 percentage point additional decrease in securities’ revenues participation for public banks after August 2011). Note that our clustered- robust standard errors may suffer an upward bias, leading to extremely conservative results. In addition, we re-conducted estimates for our baseline specification using non-weighted observations. The result reported in Columns II slightly changes the magnitude of our coefficient of interest (Public × After August 2011), but does not significantly alter our inferences. In Column III when we control for SELIC, the Diff-in-Diff coefficient remains unchanged. Also the inclusion of SELIC and Size as additional controls (Columns IV) does not alter the Diffin-Diff coefficient obtained in our baseline specification. Using quarterly time dummies, instead of SELIC as macroeconomic control variable, we re-estimated Equation 5. The coefficient of interest (Public × After August 2011) remains essentially the same not only in terms of econometric significance, but also in terms of economic magnitude (results not reported here due to space considerations but available on request). Further estimations for Equation 5 are carried out with non-clustered robust standard errors; the Diff-in-Diff coefficients obtained in all regressions are significantly higher in terms of econometric significance (results reported in the Appendix). [INSERT TABLE 7 HERE] Particularly, private banks’ asset allocation policies changed due to a rise in risk aversion; consequently, they shifted from loans to safer assets. These evidences are in line with the findings reported in the international banking literature related to the stabilization role of public banks. In addition, the results suggest that government-owned retail banks do not compete with private peers when their objective function is not only to maximize profits given risk. These evidences are also in line with the empirical studies about Brazilian banking competition, which indicate that government-owned banks do not compete with private banks. Effect on Private Banks’ Cost of Funding Table 8 reports the results of Equation 6, which measures the effect of government interventions on the cost of funding. In Column I the β1 (Public) and β2 (After August 2011) coefficients of our baseline specification are not statistically significant at conventional level. 23 Our Diff-in-Diff estimator (reported in Column I) suggests that that the government interventions in the credit market through public banks did not cause a differential effect on public banks’ cost of funding compared to private peers. In addition, we re-conducted estimates for our baseline specification using non-weighted observations. The result reported in Columns II does not change the magnitude of our coefficient of interest (Public × After August 2011). In Column III when we control for Size, Liquidity, ROE, Low quality loans and Capital adequacy, the Diff-in-Diff coefficient remains unchanged. Further estimations for Equation 6 are carried out with non-clustered robust standard errors; the Diff-in-Diff coefficients obtained in all regressions do not present statistical significance at conventional level (results reported in the Appendix). [INSERT TABLE 8 HERE] A combination of factors helps explain these results. Firstly, over 2012 and 2013, the commercial private banks reported high liquidity holdings because their funding was growing in a higher pace than their lending. This excess liquidity of the private banks is in line with the results founded in the present paper, as the private banks preferred to expand their liquid assets instead of loans supply in response to the event. Secondly, the lending capacity expansion of state-owned banks was partially supported by capital injections from the Brazilian National Treasury, totaling BRL 22.1 billion in 2012. This factor could have mitigated the public banks’ needs for obtaining funds. Regarding the bank characteristics control variables, only ROE is statistically significant at conventional level. 24 6. Conclusion This paper investigates the existence of competition between retail government-owned and private banks in the event of federal government interventions in the Brazilian bank lending over the 2009 - 2014 period. Using a Diff-in-Diff empirical approach, we found that public banks show higher loan growth, non-performing loans, lending returns, operational returns and cost of funding compared to private peers after the treatment. In addition, we find evidence of differences in the asset allocation decisions of banks, as private banks preferred an asset portfolio with a higher proportion of liquid assets holdings and less loans compared to public banks after the treatment. These findings suggest that government-owned retail banks do not compete with private peers when their objective function is not only to maximize profits given risk. Moreover, the results are in line with the findings reported in the international banking literature related to the stabilization role of public banks, as well as, with the empirical studies about Brazilian banking competition, which indicate that government-owned banks do not compete with private banks. Lastly, our paper’s findings have some important implications. First, we contribute to the banking empirical literature by investigating the existence of competition between public and private banks with a different methodological approach. Additionally, our results shed light on policymakers’ future actions in the Brazilian bank lending market, since it suggest that the increase in the lending growth rate of public banks by government interventions aiming to accelerate economic activity, tightened the private banks’ loan supply policy showing a crowding out effect. 25 7.
