Recognizing that many banks suffered trading losses that notably exceeded their minimum capital requirements during the recent crisis, the Basel Committee on Banking Supervision (2011) revised its regulatory framework for trading portfolios. In this paper, we compare: (1) the relative...

In setting minimum capital requirements for trading portfolios, the Basel Committee on Banking Supervision (1996, 2011a, 2013) initially used Value-at-Risk (VaR), then both VaR and stressed VaR (SVaR), and most recently, stressed Conditional VaR (SCVaR). Accordingly, we examine the use of SCVaR...

The purpose of our study is to provide an overview of the revisions made to the Basel III regulatory framework in the aftermath of the 2007 crisis, with regard to measuring the risk associated with positions included in the trading book. The calculation of the regulatory capital requirement...

Euro area governments have committed to break the doom loop between bank risk and sovereign risk. But policymakers have not reached consensus on whether and how to reform the regulatory treatment of banks' sovereign exposures. To inform policy discussions, this paper simulates portfolio...

Euro area governments have committed to break the doom loop between banks and sovereigns. But policymakers disagree on how to treat sovereign exposures in bank regulation. Our contribution is to model endogenous sovereign portfolio reallocation by banks in response to regulatory reform....

In this paper, we use detailed data on the sovereign debt holdings of all German banks to analyse the determinants of sovereign debt exposures and the implications of sovereign exposures for bank risk. Our main findings are as follows. First, sovereign bond holdings are heterogeneous across...

Banks and other lenders often transfer credit risk to liberate capital for further loan intermediation. This paper aims to explore the design, prevalence and effectiveness of credit risk transfer (CRT). The focus is on the costs and benefits for the efficiency and stability of the financial...

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...

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...
