This paper reviews the cost-benefit analysis, or “regulatory impact analysis” (RIA), in US bank regulators’ risk-based capital (RBC) rule proposals. We review the principles of cost-benefit analysis and its application by US bank regulators. We provide a brief background on RBC rules and...

The traditional approach to the stress testing of financial institutions focuses on capital adequacy and solvency. Liquidity stress tests have been applied in parallel to and independently from solvency stress tests, based on scenarios which may not be consistent with those used in solvency...

This paper presents the analysis underpinning the ESRB Recommendation on guidance on setting countercyclical buffer rates (ESRB 2014/1). The Recommendation is designed to help authorities tasked with setting the countercyclical capital buffer (CCB) to operationalise this new macroprudential...

We propose an improved methodology for modelling potential scenario paths of banks' riskweighted assets, which drive the denominator of capital adequacy ratios. Our approach centres on modelling the internal risk structure of bank portfolios and thus aims to provide more accurate estimations...

A bank's liquidity risk lays in the intersection of funding risk and market liquidity risk. We offer a mathematical framework to make Economic Capital and RAROC sensitive to illiquidity. We introduce the concept of a liquidity cost profile as a quantification of a bank's illiquidity at balance...

The Basel 3 Liquidity Coverage Ratio (LCR) is a micro prudential instrument to strengthen the liquidity position of banks. However if in extreme scenarios the LCR becomes a binding constraint, the interaction of bank behaviour with the regulatory rule can have negative externalities. We simulate...

Banks may be unable to refinance short-term liabilities in case of solvency concerns. To manage this risk, banks can accumulate a buffer of liquid assets, or strengthen transparency to communicate solvency. While a liquidity buffer provides complete insurance against small shocks, transparency...

We propose a methodology for measuring the market-implied capital of banks by subtracting from the market value of equity (market capitalization) a credit-spread-based correction for the value of shareholders' default option. We show that without such a correction, the estimated impact of a...
