Freixas, X., Laeven, L., Peydró, J.-L. (2015). Systemic Risk, Crises, and Macroprudential Regulation. Cambridge (MA): MIT Press. DOI

Abstract: The recent financial crisis has shattered all standard approaches to banking regulation. Regulators now recognize that banking regulation cannot be simply based on individual financial institutions’ risks. Instead, systemic risk and macroprudential regulation have come to the forefront of the new regulatory paradigm. Yet our knowledge of these two core aspects of regulation is still limited and fragmented. This book offers a framework for understanding the reasons for the regulatory shift from a microprudential to a macroprudential approach to financial regulation. It defines systemic risk and macroprudential policy, cutting through the generalized confusion as to their meaning; contrasts macroprudential to microprudential approaches; discusses the interaction of macroprudential policy with macroeconomic policy (monetary policy in particular); and describes macroprudential tools and experiences with macroprudential regulation around the world. The book also considers the remaining challenges for establishing effective macroprudential policy and broader issues in regulatory reform. These include the optimal size and structure of the financial system, the multiplicity of regulatory bodies in the United States, the supervision of cross-border financial institutions, and the need for international cooperation on macroprudential policies.

Chapter abstract: Since the beginning of the financial crisis, academics and regulators on both sides of the Atlantic have started to debate the implications of securities trading by banks. New regulation limits security trading, fearing that this could crowd out lending to the real economy or could facilitate risk-shifting by financial institutions. On the other hand, banks may use security trading for hedging purposes or, particularly during a crisis, to access public liquidity. Only very recently have researchers begun to have access to micro data at the security level on banks’ trading activities, and they are starting to bring robust evidence on these issues. This chapter reviews the potential costs and benefits of combining traditional intermediation activity with security trading and discusses the recent empirical evidence.

Abstract: We show that negative monetary policy rates induce systemic banks to reach-for-yield. For identification, we exploit the introduction of negative deposit rates by the European Central Bank in June 2014 and a novel securities register for the 26 largest euro area banking groups. Banks with more customer deposits are negatively affected by negative rates, as they do not pass negative rates to retail customers, in turn investing more in securities, especially in those yielding higher returns. Effects are stronger for less capitalized banks, private sector (financial and non-financial) securities and dollar-denominated securities. Affected banks also take higher risk in loans.

Peydró, J.-L., Rodriguez-Tous, F., Tripathy, J. & Uluc, A. (2022). Macroprudential policy, mortgage cycles and distributional effects: Evidence from the UK. Review of Financial Studies, accepted (Bank of England WP)

Abstract: Macroprudential regulators worldwide have introduced regulations to limit household leverage in light of existing evidence which suggests that high leverage is associated with household distress during crisis. We analyse the distributional effects of such a macroprudential policy on mortgage and house price cycles. For identification, we exploit the universe of UK mortgages and a 15%-limit imposed in 2014 on lenders — not households — for high loan-to-income ratio (LTI) mortgages. Despite some regulatory arbitrage (eg increases in LTV and average loan size), more-constrained lenders issue fewer high-LTI mortgages. Partial substitution by less-constrained lenders leads to overall credit contraction to low-income borrowers in local-areas more exposed to constrained-lenders, lowering house price growth. Following the Brexit referendum (which led to house-price correction), the 2014-policy strongly implies — via lower pre-correction debt — better house prices and mortgage defaults during an episode of house price correction.

Earlier version: 'Household credit, global financial cycle, and macroprudential policies: Credit register evidence from an emerging country'

Abstract: We show that macroprudential policies dampen the impact of global financial conditions on local bank credit cycles. For identification, we exploit variation in the U.S. VIX and household and business credit registers in an emerging market economy where banks depend on foreign funding and macroprudential measures vary over the full cycle. Our results suggest that when the VIX is low, tighter macroprudential policies reduce household lending, notably for riskier (FX and high DSTI) loans and by banks dependent on foreign funding. Moreover, they increase (less regulated) local currency lending to real estate firms, while leaving business lending to other firms unchanged. Such periods are associated with less subsequent total lending to households and firms and with a lower share of FX loans at the local level. Consistently, when the VIX is low, tighter macroprudential policies dampen house prices and economic activity.

Andersen, A.L., Johannesen, N., Jørgensen, M. & Peydró, J.-L. Monetary policy and inequality. Journal of Finance, forthcoming. PDF

Abstract: We analyze the distributional effects of monetary policy on income, wealth and consumption. We use administrative household-level data covering the entire population in Denmark over the period 1987-2014 and exploit a long-standing currency peg as a source of exogenous variation in monetary policy. We consistently find that the gains from softer monetary policy in terms of income, wealth and consumption are monotonically increasing in the ex ante income level. The distributional effects reflect systematic differences in exposure to the various channels of monetary policy, especially non-labor channels (e.g. leverage and assets). Our estimates imply that softer monetary policy increases income inequality.

Abstract: We study how capital controls and domestic macroprudential policy tame credit supply booms, either directly or by enhancing the local bank-lending channel of monetary policy. We exploit credit registry data and the introduction of capital controls on foreign exchange (FX) debt inflows and increase of reserve requirements on domestic bank deposits in Colombia during a boom. We find that capital controls strengthen the bank-lending channel. Increasing the local monetary policy rate widens the interest rate differential with the U.S.; hence, relatively more FX-indebted banks carry-trade cheap FX-funds with expensive peso lending, especially towards riskier firms. Capital controls tax FX-debt and break the carry-trade. Differently, raising reserve requirements on domestic deposits directly reduces credit supply, particularly for riskier firms, rather than enhancing the bank-lending channel. Importantly, banks differentially finance credit with domestic vis-à-vis FX-financing; hence, capital controls and domestic macroprudential policy complementarily mitigate the credit boom and related bank risk-taking.

Abstract: Do financial crises radicalize voters? We study Germany's 1931 banking crisis, collecting new data on bank branches and firm-bank connections. Exploiting cross-sectional variation in pre-crisis exposure to the bank at the center of the crisis, we show that Nazi votes surged in locations more affected by its failure. Radicalization in response to the shock was exacerbated in cities with a history of anti-Semitism. After the Nazis seized power, both pogroms and deportations were more frequent in places affected by the banking crisis. Our results suggest an important synergy between financial distress and cultural predispositions, with far-reaching consequences.

Abstract: We show that negative interest rate policy (NIRP) has expansionary effects on credit supply through a portfolio rebalancing channel. By shifting down and flattening the yield curve, NIRP differs from rate cuts just above the zero-lower-bound and has effects similar to QE. For identification, we exploit ECB’s NIRP and the Italian credit register and, for external validity, European and U.S. datasets. NIRP affects more banks with higher ex-ante liquid assets, including net interbank positions. More exposed banks reduce liquid assets, expand credit supply, especially to financially-constrained firms, and cut loan rates, inducing firms to increase investment and the wage bill.

Abstract: Monetary policy transmission may be impaired if banks rebalance their portfolios toward securities. We identify the bank lending and risk-taking channels of monetary policy by exploiting – Italy’s unique – credit and security registers. In crisis times, with higher central bank liquidity, less capitalized banks react by increasing securities over credit supply, inducing worse firm-level real effects. However, they buy securities with lower yields and haircuts. Unlike in crisis times, in precrisis times, securities do not crowd out credit supply. The substitution from lending to securities in crisis times helps less capitalized banks to repair their balance sheets and restart credit supply with a one-year lag.

Previously circulated as 'International financial integration, crises and monetary policy: Evidence from the Euro Area interbank crises'

Abstract: We analyze how the Lehman and sovereign crises affect cross-border interbank liquidity, exploiting euro-area proprietary interbank data, crisis and monetary shocks, and loan terms to the same borrower during the same day by domestic versus foreign lenders. Crisis shocks reduce the supply of cross-border liquidity, with stronger volume than pricing effects. On the extensive margin, results suggest that the cross-border credit crunch is independent of borrower quality, while—on the intensive margin—riskier borrower banks suffer more. Moreover, the cross-border liquidity crunch is substantially stronger for term loans, and weaker for foreign lender banks that have a subsidiary in the same country than the borrower. Finally, nonstandard monetary policy improves interbank liquidity, but without fostering strong re-integration of cross-border interbank markets.

Abstract: We investigate the connections between bank capital regulation and the prevalence of lightly regulated nonbanks (shadow banks) in the U.S. corporate loan market. For identification, we exploit a supervisory credit register of syndicated loans, loan-time fixed effects, and shocks to capital requirements arising from surprise features of the U.S. implementation of Basel III. We find that less-capitalized banks reduce loan retention, particularly among loans with higher capital requirements and at times when capital is scarce, and nonbanks step in. This reallocation is associated with important adverse effects during the 2008 crisis: loans funded by nonbanks with fragile liabilities are less likely to be rolled over and experience greater price volatility.

Abstract: Banking crises are recurrent phenomena, often induced by excessive bank risk-taking, which may be due to behavioural reasons (over-optimistic banks neglecting risks) and to conflicts of interest between bank shareholders/managers and debtholders/taxpayers (banks exploiting moral hazard). We test whether US banks’ stock returns in the 2007-08 financial crisis are associated with bank insiders’ sales of their own bank’s shares in the period prior to 2006Q2 (the peak and reversal in real estate prices). We find that top-five executives’ sales of shares predict bank performance during the crisis. Interestingly, effects are insignificant for the sales of independent directors and other officers. Moreover, the top-five executives’ impact is stronger for banks with higher exposure to the real estate bubble, where a one standard deviation increase of insider sales is associated with a 13.33 percentage point drop in stock returns during the crisis period. Finally, even though bankers in riskier banks sold more shares (furthering their own interests), they did not change their bank’s policies, e.g. by reducing bank-level exposure to real estate. The informational content of bank insider trading before the crisis suggests that insiders knew that their banks were taking excessive risks, which has important implications for theory, public policy, and the understanding of crises, as well as a supervisory tool for early warning signals.

Previously circulated as ‘Local versus aggregate lending channels: The effects of securitization on corporate credit supply in Spain’

Abstract: This paper studies credit booms exploiting the Spanish matched credit register over 2001-2009. We extend Khwaja and Mian's (2008) loan-level estimator by incorporating firm-level general equilibrium adjustments. Higher ex-ante bank real-estate exposure increases credit supply to non-real-estate firms, but effects are neutralized by firm-level adjustments for firms with existing banking relationships. However, higher bank real-estate exposure increases risk-taking, by relaxing standards of existing borrowers (cheaper, longer-term and less collateralized credit), and by expanding credit on the extensive margin to first-time borrowers that default substantially more. Results suggest that the mechanism at work is greater liquidity via securitization of real-estate assets.

The real effects of the bank lending channel

Akin, O., Coleman, N.S., Fons-Rosen, C. & Peydró, J.-L. (2021). Political connections and informed trading: Evidence from TARPFinancial Management 50(3), 619–644 DOI Open Access

Voted number 1 article in the Fall 2021 issue of Financial Management.

Abstract: We study insider trading behavior surrounding the largest bank bailout in history: Troubled Asset Relief Program (TARP). In politically connected banks, insider buying during the pre-TARP period is associated with increases in abnormal returns around bank-specific TARP announcement; for unconnected banks, trading and returns are uncorrelated. Results hold across insiders within the same bank and are stronger for finance-related government connections. Through a Freedom of Information Act request, we obtained the previously undisclosed TARP funds requested; the ratio of received to requested funds correlates both with abnormal returns and insider buying behavior in connected banks.

Abstract: We identify the international credit channel by exploiting Mexican supervisory data sets and foreign monetary policy shocks in a country with a large presence of European and U.S. banks. A softening of foreign monetary policy expands credit supply of foreign banks (e.g., U.K. policy affects credit supply in Mexico via U.K. banks), inducing strong firm‐level real effects. Results support an international risk‐taking channel and spillovers of core countries’ monetary policies to emerging markets, both in the foreign monetary softening part (with higher credit and liquidity risk‐taking by foreign banks) and in the tightening part (with negative local firm‐level real effects).

Abstract: Recent studies of monetary policy in developing countries document a weak bank lending channel based on aggregate data. In this paper, we bring new evidence using Uganda's supervisory credit register, with microdata on loan applications, volumes and rates, coupled with unanticipated variation in monetary policy. We show that a monetary contraction reduces bank credit supply—increasing loan application rejections and tightening loan volume and rates—especially for banks with more leverage and sovereign debt exposure. There are associated spillovers on inflation and economic activity—including construction permits and trade—and even social unrest.

Within the Highly Cited Articles in Economic Policy

Abstract: We analyse the impact of standard and non-standard monetary policy on bank profitability. We use both proprietary and commercial data on individual euro area bank balance-sheets and market prices. Our results show that a monetary policy easing – a decrease in short-term interest rates and/or a flattening of the yield curve – is not associated with lower bank profits once we control for the endogeneity of the policy measures to expected macroeconomic and financial conditions. Accommodative monetary conditions asymmetrically affect the main components of bank profitability, with a positive impact on loan loss provisions and non-interest income offsetting the negative one on net interest income. A protracted period of low monetary rates has a negative effect on profits that, however, only materializes after a long time period and is counterbalanced by improved macroeconomic conditions. Monetary policy easing surprises during the low interest rate period improve bank stock prices and CDS.

Abstract: To study the impact of macroprudential policy on credit supply cycles and real effects, we analyze dynamic provisioning. Introduced in Spain in 2000, revised four times, and tested in its countercyclicality during the crisis, it affected banks differentially. We find that dynamic provisioning smooths credit supply cycles and, in bad times, supports firm performance. A 1 percentage point increase in capital buffers extends credit to firms by 9 percentage points, increasing firm employment (6 percentage points) and survival (1 percentage point). Moreover, there are important compositional effects in credit supply related to risk and regulatory arbitrage by nonregulated and regulated but less affected banks.

Macroprudential policy, countercyclical bank capital buffers, and credit supply: Evidence from the spanish dynamic provisioning experiments

Ippolito, F., Peydró, J.-L., Polo, A. & Sette, E. (2016). Double bank runs and liquidity risk managementJournal of Financial Economics, 122(1), 135–54. DOI. PDF

Abstract: By providing liquidity to depositors and credit-line borrowers, banks can be exposed to double-runs on assets and liabilities. For identification, we exploit the 2007 freeze of the European interbank market and the Italian Credit Register. After the shock, there are sizeable, aggregate double-runs. In the cross-section, credit-line drawdowns are not larger for banks more exposed to the interbank market; however, they are larger when we condition on the same firms with multiple credit lines. We show that, ex-ante, more exposed banks actively manage their liquidity risk by granting fewer credit lines to firms that run more during crises.

Double bank runs and liquidity risk management

Abstract: We analyze securities trading by banks during the crisis and the associated spillovers to the supply of credit. We use a proprietary data set that has the investments of banks at the security level for 2005–2012 in conjunction with the credit register from Germany. We find that—during the crisis—banks with higher trading expertise (trading banks) increase their investments in securities, especially in those that had a larger price drop, with the strongest impact in low-rated and long-term securities. Moreover, trading banks reduce their credit supply, and the credit crunch is binding at the firm level. All of the effects are more pronounced for trading banks with higher capital levels. Finally, banks use central bank liquidity and government subsidies like public recapitalization and implicit guarantees mainly to support trading of securities. Overall, our results suggest an externality arising from fire sales in securities markets on credit supply via the trading behavior of banks.



Securities trading by banks and credit supply: Micro-evidence from the crisis

Peydró, J.-L. (2016). Macroprudential policy and credit supply. Swiss Journal of Economics and Statistics, 152(4), 305–318. DOI  Open Access

Based on the Keynote speech at the CEPR St-Gallen FGN conference on “Banks, Financial Markets and Economic Growth”.

Abstract: In this paper we analyze financial crises and the interactions of macroprudential policy and credit. Financial crises are recurrent systemic phenomena, often triggering deep and long-lasting recessions with large reductions in aggregate welfare, output and employment. Importantly for policy, systemic financial crises are typically not random events triggered by exogenous events, but they tend to occur after periods of rapid, strong credit growth. Moreover, a credit crunch tends to follow in a financial crisis with negative aggregate real effects. Macroprudential policy softens the credit supply cycles, with important positive effects on the aggregate real economy in crisis times.
