A flood of cash poured into the Federal Reserve's reverse repurchase facility on Tuesday, the last trading day of 2024, pushing the facility's usage to its highest level since early summer. Money market funds and other eligible institutions had $473.5 billion sitting on the Fed's books. The surge in usage was not unexpected, with large inflows of cash often taking place at the end of the quarter and at the end of the year as companies manage their balance sheets, where there are typically brief adjustments. Tuesday's cash inflows were the highest since inflows of $664.6 billion began on the last trading day of the second quarter, and also topped the $465.6 billion seen at the end of the third quarter on Sept. 30.
