I am interested in how bank regulation might be a major contributor to crises, by constraining how bank balance sheets can be deployed. This might be contributing to obscured risk taking, transforming risks or regulatory arbitrage. 1. How much did basel risk weights for short term interbank lending contribute to the asian financial crisis? Rather than lending directly to businesses, banks lent to other institutions that would lend to businesses. risk weights encouraged large A-L mismatches. 2. GFC - basel risk weights encouraged holding triple-A securities which were really obscuring much larger subprime risks. (AAA tranche of a CDO holding mezzanine MBS) 3. 2023 - Banking crisis caused by duration exposure encouraged by basel risk weights which don't accoutn for duration risk. Banks have to take duration risk to make money, smb lending is heavily penalized? 4. How does bank regulation contribute to the S&L crisis?
