At the end of last week, the Federal Reserve released its weekly report on the U.S. banking system, which showed that amid the turmoil that's engulfed the banking sector, there was an outflow of deposits from smaller banks in mid-March — though not on a scale that appears overly worrisome. This is a sign that while bank deposit outflows are real, it does not appear to have amounted to a cascade of withdrawals.
Context: That amounts to the largest single-week drop in small bank deposits on record, in dollar terms, in data that goes back to 1973. However, in percentage terms, there were numerous weeks in the 1980s with steeper drops, as well as one in 2007.
