Since March 2020 the Eurosystem has provided conditional subsidies to some Euro Area banks, via the new terms of its Targeted Longer-Term Refinancing Operations (TLTRO). Under this program, banks can borrow from the Eurosystem at a rate as low as -1%, conditional on their lending performance to the real economy. By keeping the borrowed funds on their central bank accounts at -0.5%, banks can earn a 50 basis points profit, a significant margin by money market standards. This paper uses the new Euro-Area credit registry data (AnaCredit) to assess the effectiveness of this measure. To overcome reverse causality, we use a novel identification strategies based on the cut-off dates set before the pandemic and unexpected changes of parameters. We find a significant effect of TLTRO on credit supply.
