Event Summary

The seventh annual Conference on Bank Regulation of the Bank Policy Institute & Columbia University School of International and Public Affairs took place on March 1, 2023. Each year, the conference brings together academics, banking agency economists, and market participants to discuss the latest research on banking and bank regulation. This year’s theme was bank regulation and the business cycle. The conference covered bank capital and lending dynamics through the cycle, evidence on countercyclical capital buffers and temporary regulatory actions, and expected next steps for capital and liquidity regulation.  The conference was held under Chatham House rule.

The first session consisted of one empirical and one theoretical paper examining effects of market discipline and counter-cyclical buffer requirements on bank capital and lending dynamics.

The empirical paper in this session, presented by Cyril Couaillier from the European Central Bank,  examines how firms choose and then attain their target capital ratio. The analysis is based on quarterly, target capital ratios manually collected from reports and investment presentations of 74 European banks, merged with bank-level financial and balance sheet information and macroeconomic data, covering the period from  the first quarter of 2014 through fourth quarter of  2021. One key takeaway is that changes in the target move with change in regulatory capital requirements, which makes the internal target pro-cyclical. However, the co-movement is less than one-to-one, which a panel discussant suggested might reflect conservatism in the regulatory requirements. Another empirical finding is that banks adjust faster from the downside than the upside to the target.

The theory paper, presented by Yasuo Terajima from the Bank of Canada, develops a dynamic simulation model with a stochastic macroeconomic state (normal and crises), bank-specific loan failure rate shocks and an endogenous bank default that generates a risk premium on the bank’s wholesale funding that entails market discipline. Banks in the model also are subject to capital requirements that allow for a  countercyclical buffer (CCyB). Simulations are conducted for banks differentiated by initial capital ratio. The results confirm the benefits of a CCyB over constant capital requirements: smoother credit supply and reduced bank failure probabilities. Effects of a CCyB and of market discipline vary by bank capital level; for instance, a CCyB is particularly beneficial for banks with lower capital ratios.

The second panel of the conference consisted of two empirical studies examining effects of capital relief during the COVID-19 pandemic.

The first paper, presented by Aniruddha Rajan from the Bank of England, examines the effects of easing of the CCyB on mortgage lending in the UK. The authors find that banks used the CCyB relief in part to increase their precautionary capital surpluses over the regulatory threshold, and that this effect was larger for low surplus banks. In addition, the study tests the benefits of releasability by exploiting the fact that the cut to the CCyB in the UK at the onset of the crisis varied across banks based their relative exposure to UK credit risk-weighted assets. Results indicate that banks for whom a greater proportion of their regulatory buffers would have been released did not materially increase capital surpluses over 2020 and were able to lend more and take on more credit risk.

The second paper, presented by Alessio Reghezza from the European Central Bank, examines the effects on bank lending of three different regulatory capital relief measures in Europe: change in the composition of capital instruments required (a permanent reduction in CET1), release of the CCyB, and the easing of prudential guidance. The empirical approach compared effects across different banks that are lending to the same borrower, using credit registry data. The analysis finds that the more concrete capital relief offered by the first two measures led to increased lending while changes in guidance had little effect. Effects were stronger for banks that were closer to the regulatory buffer threshold.

The keynote address by former Federal Reserve vice chairman Randall Quarles covered a range of timely topics in monetary policy and banking regulation.

The third panel focused on instances of temporary change to regulatory policy during the pandemic: the exemption of bank reserves and Treasury securities from the denominator of the Supplementary Leverage Ratio in the U.S., and suspension of dividend payouts in the EU. 

The first paper of the panel, presented by Marcelo Rezende, Federal Reserve Board, examines the effects of the SLR and temporary SLR relief on banks’ participation in U.S. treasury markets. The paper first considers banks’ responses to the large, unexpected increase in credit line drawdowns that occurred at the start of the pandemic, which  mechanically increased the denominator of the SLR ratio as some assets moved from off-balance sheet to on-balance sheet. The analysis finds that credit line drawdowns led to a large decline in treasury market participation by banks, but this effect is weaker for banks with large SLR buffers. These effects diminished  after the Federal Reserve exempted reserves and Treasuries from the denominator of the SLR formula. The study suggests that banks’ ability to participate in markets for safe assets may be curtailed by leverage regulations.

The second paper, presented by Ernest Dautović, European Central Bank, examines the impact of the ECB’s dividend distribution recommendations on banks’ lending and loss absorption capacity during the pandemic, differentiating across banks based on their pre-pandemic dividend plans. Banks that reversed previously planned dividend distributions increased their lending and their loss provisions relative to banks that did not revise their plans. The results suggest that the recommendations were successful in helping to maintain the flow of credit and enhancing resilience to credit losses.

A final, policy panel focused on what is next for banking regulation. The panel discussion commenced with lessons learned from the Covid-19 crisis, including recognition of procyclical elements of the regulatory framework and ways to mitigate them. Panel participants were Tomoko Amaya from the Japanese Financial Services Agency, Mark Van Der Weide from the Federal Reserve Board, Paul Glasserman from Columbia University, and Andrew Nash from Morgan Stanley.
