We use high-frequency interbank payments data to trace deposit flows in March 2023 and identify twenty-two banks that suffered a run, significantly more than the two that failed but fewer than the number that experienced large negative stock returns. The runs were driven by a small number of large depositors and were related to weak fundamentals. However, we find evidence for the importance of coordination because run banks were disproportionately publicly traded and many banks with similarly bad fundamentals did not suffer a run. Banks survived the run by borrowing new funds and raising deposit rates, not by selling securities.
