Banks' holding of reasonable capital buffers in excess of minimum requirements could alleviate the procyclicality problem potentially exacerbated by the rating-sensitive capital charges of Basel II. Determining the required buffer size is an important risk management issue for banks, which the...

We show in a theoretical model that the introduction of the leverage ratio requirement, when it interacts with the risk-based IRB capital requirements, might lead to less lending to low-risk customers and to increased lending to high-risk customers. If such allocational effects are...

We study the effects on credit allocation and bank stability of introducing a leverage ratio requirement (LRR) on top of risk-based capital requirements, as in Basel III. For the current 3% LRR, both low-risk and high-risk loan rates and volumes remain essentially unchanged, because banks...

Basel III has introduced a non-risk-weighted leverage ratio requirement (LRR) which complements the internal ratings based (IRB) capital requirements. It provides a backstop against model risk which arises if some loans get incorrectly rated and become toxic. We study the effects of the LRR on...

This paper tests how closely the three leading market-based systemic risk measures (SRM) agree with the list of global systemically important banks (G-SIB) from the Financial Stability Board (FSB) and how closely they match the categorization of G-SIBs into the five systemic risk buckets used by...
