The global financial crisis has highlighted the limitations of risk-sensitive bank capital ratios. To tackle this problem, the Basel III regulatory framework has introduced a minimum leverage ratio, defined as a banks Tier 1 capital over an exposure measure, which is independent of risk...

This paper presents a general equilibrium model with a dynamic banking sector to characterize optimal size-dependent bank capital regulation (CR). Bank leverage choices are subject to the risk-return trade-off: high leverage increases expected return on capital, but also increases return...

We study the transmission mechanisms of liquidity and capital regulations as well as their effects on the economy and welfare. We propose a macro-economic model in which a regulator faces the following trade-off. On the one hand, banking regulations may reduce the aggregate supply of credit. On...

This paper provides some general lessons for the design of counter-cyclical capital buffers. Its main empirical contribution is to analyze conditioning variables which could guide the build-up and release of capital. A major distinction for counter-cyclical capital schemes is whether...

This study outlines a methodology for mapping the increases in capital and liquidity requirements proposed under Basel III to bank lending spreads. The higher cost associated with a one percentage point increase in the capital ratio can be recovered by increasing lending spreads by 15 basis...

Bank capital ratios have increased steadily since the financial crisis. For a sample of 94 large banks from advanced and emerging economies, retained earnings account for the bulk of their higher risk-weighted capital ratios, with reductions in risk weights playing a lesser role. On average,...

We assess the dynamics of volatility spillovers among global systemically important banks (G-SIBs). We measure spillovers using vector-autoregressive models of range volatility of the equity prices of G-SIBs, together with machine learning methods. We then compare the size of these spillovers...

Do macroprudential regulations on residential lending influence commercial lending behavior too? To answer this question, we identify the compositional changes in banks' supply of credit using the variation in their holdings of residential mortgages on which extra capital requirements were...

Banks allocate capital across business units while facing multiple constraints that may bind contemporaneously or only in future states. When risks rise or risk management strengthens, a bank reallocates capital to the more efficient unit. This unit would have generated higher constraint- and...

To the best of our knowledge, this is the first study to estimate the effect of liquidity regulation on bank balance sheets. It takes advantage of the fact that not all banks were made subject to tighter liquidity regulation by the UK Financial Services Authority (FSA) in 2010. Under this new...
