The effect of the Federal Reserve's lending facility on PPP lending by commercial banks

We investigate whether the Federal Reserve's Paycheck Protection Program Liquidity Facility (PPPLF) boosted commercial bank Paycheck Protection Program (PPP) lending. To determine whether this facility had a causal effect, we use pre-existing familiarity with the Federal Reserve's discount window as an instrumental variable. We show that the PPPLF materially bolstered bank PPP lending and provided a meaningful funding backstop for banks that did not use the facility. Our paper is one of the first to quantitatively illustrate the effectiveness of a central bank facility as a funding backstop.
