Relationship Lending during a Trust Crisis on the Interbank Market: A Friend in Need is a Friend Indeed

We exploit uncertainty regarding banks' involvement in money laundering activities as a natural experiment to study the functioning of the interbank market in uncertain times. We show that bank couples with a stronger relationship (i.e., more frequent and reciprocal interactions before the event) are more likely to continue lending to one another, and at lower interest rates. This is in line with a “helping hand” or “flight to friends” hypothesis during crisis.
