The Federal Reserve’s overnight reverse repo facility took in just $30 million from six counterparties on Monday, a fraction of the $2 trillion in daily usage that marked the facility’s peak in 2021. The latest figure underscores how far the RRP tool — once a key indicator of excess liquidity in the banking system — has retreated as the Fed tightens policy and Treasury bills become more attractive.
Why the RRP facility shrank
During the pandemic-era easing, the Fed’s reverse repo facility was a sink for the flood of cash that money market funds couldn’t place elsewhere. At its high point in December 2021, daily usage hit $2.04 trillion, as funds parked cash to earn a guaranteed rate. But the Fed’s rate hikes and the corresponding rise in Treasury bill yields changed the math. Money market funds now find it more profitable to buy short-term government debt than to lend to the Fed via reverse repos.
The shift started in early 2023 and accelerated this year. The $30 million operation on Monday is among the lowest daily totals on record, a far cry from the trillion-dollar figures that dominated headlines two years ago.
What the $30 million operation means
Monday’s reverse repo operation involved just six counterparties, a tiny number compared to the dozens that regularly participated during the facility’s heyday. The small size suggests that money market funds are fully deployed in Treasury bills and other short-term instruments, leaving little need to use the Fed’s facility.
Some analysts had speculated that the RRP facility could serve as a buffer against reserve scarcity, but the current data shows that buffer has all but disappeared. The decline in RRP usage also coincides with a reduction in the Fed’s balance sheet, which is shrinking as the central bank lets Treasuries and mortgage-backed securities roll off without reinvestment.
Broader implications for money markets
The collapse of reverse repo usage is a sign that the financial system’s excess liquidity has been drained more than many expected. With the RRP facility now below $100 billion for weeks, the Fed’s next moves could have a direct impact on overnight lending rates. If reserves become too scarce, the federal funds rate could drift above the Fed’s target range, forcing the central bank to adjust its interest on reserve balances rate or even pause the balance sheet runoff.
Fed officials have said they are watching money market conditions closely. The next key test will come in mid-September, when a surge in corporate tax payments and Treasury auction settlements could temporarily tighten liquidity. That’s when the market will see whether the RRP facility really is a thing of the past.
For now, the $30 million reverse repo operation is a quiet milestone — a reminder that the era of trillion-dollar overnight parking has ended, and a new phase in the Fed’s liquidity management has begun.
