Using supervisory data for US banks, we evaluate the alignment of Basel II/III AIRB (Advanced Internal Ratings Based) risk estimates with portfolio risk. We use loan performance as a direct measure of portfolio risk as well as less direct market-based measures. Our results document that loan...

This paper provides an overview of stress-testing methodologies in Europe, with a focus on the advancements made by the European Central Bank's Financial Stability Committee Working Group on Stress Testing (WGST). Over a four-year period, the WGST played a pivotal role in refining stress-testing...

In its October 2013's consultative paper for a revised market risk framework (FRTB), and subsequent versions published thereafter, the Basel Committee suggests that non-securitization credit positions in the trading book be subject to a separate Default Risk Charge (DRC, formally Incremental...

The United States is now committed to using two relatively sophisticated approaches to measuring capital adequacy: Basel III and stress tests. This paper shows how stress testing could mitigate weaknesses in the way Basel III measures credit and interest rate risk, the way it measures bank...

Our paper investigates Indonesia's systemically important banks (SIBs) using theoretical approaches-CoVaR, marginal expected shortfall (MES), and SRISK-to compare with the Basel guidelines as benchmark. We use Indonesian banks' market and supervisory data over the 2008-2019 period. The research...

The Basel capital adequacy ratios lost credibility with financial markets during the crisis. This paper argues that failure was the result of the reliance of the Basel standards on overstated asset values in reported equity capital. The United States' stress tests were able to assist in...

The internal ratings-based (IRB) approach maps banks’ risk profiles more adequately than the standardized approach. After switching to IRB, banks’ risk-weighted asset (RWA) densities are thus expected to diverge, especially across countries with different supervisory strictness and risk...

This article describes the Basel II capital rules for securitization exposures, explaining the considerations that influenced regulators' decisions, the approaches for calculating capital and how banks will apply them, the financial engineering that underlies the different approaches and the...
