The global financial crisis has led to the increasing importance of regulation that relies on banks’ internal risk models. Model-based regulation aims at incentivizing banks to accurately measure risk via constantly evolving models. This paper offers a theoretical model that explores how banks’ risk tolerance affects the optimal trade-offs between capital requirements and penalties for underreporting risk. The model suggests that an increase in banks’ risk tolerance leads to higher penalties for underreporting risk. I then use hand-collected data on banks’ model revisions and outcomes. I document that banks systematically underreport risk and despite the pressure from regulators do not improve the internal models. The paper suggests that model-based regulation is flawed and calls for more supervisory training to alleviate the inefficiencies.
Strategic Risk-Modelling by Banks: Evidence from Inside the Black Box (with
Mike Mariathasan
and
Ouarda Merrouche)
Regulators condition bank capital on risk but face the challenge of measuring risk accurately. Capital requirements thus often rely on inputs from banks’ internal risk models. We investigate how banks’ modelling choices relate to predicted Value-at-Risk (VaR) and the frequency with which predictions are exceeded based on hand-collected data. We document systematic differences in VaR and VaR violations for the chosen simulation method, holding period and historical data use, and show that banks can get systematically lower capital requirements by making certain modelling choices. Our findings point to strategic modelling and corroborate recent evidence on banks’ adoption of similar models making the system as a whole more vulnerable.
