Banks of a feather: The informational advantage of being alike

No 09/2023, Discussion Papers from Deutsche Bundesbank

Abstract: Banks lend more to banks that are similar to them. Using data from the German credit register and proprietary supervisory data on the quality of banks' loan portfolio, we show that a similar portfolio of the lending and borrowing bank helps to overcome information asymmetries in interbank markets. While interbank lenders generally do not adjust their lending to information on the counterparty's portfolio quality, banks with an exposure to similar industries and regions strongly react to this private information. Lending between similar banks is particularly important for borrowers with an opaque loan portfolio, which do not obtain credit from dissimilar peers.
