We then build a quant- itative model of bank behavior taking as exogenous inputs the aggregate and idiosyncratic components of problem loans, interest rate spreads and deposit shocks, seeking to under- stand decisions regarding new loans provision, access to wholesale funding and defaults. The model generates highly procyclical loan supply and banks can curtail new lending very ag- gressively in response to background risk shocks, such as an increase in bad loans. Bank failures, though, are strongly countercyclical. Relative to a baseline recession, in a reces- sion simultaneously accompanied by a temporary freeze in the money market, bank defaults increase by a factor of three and credit supply drops by 2.5 percentage points more.enBankingLeverageUninsurable RiskCapital AdequacyBank FailuresQuantitative ModelsUninsurable Risks, Bank Defaults and Loan Supplyworking paper
