Overnight Reverse Repurchase Agreement Facility

A Federal Reserve facility where eligible non-banks lend cash to the Fed overnight against Treasury collateral, putting a hard floor under short-term interest rates.

Also called: reverse repo facility, overnight reverse repo.

Money market funds, government-sponsored enterprises and dealers hold enormous cash balances but cannot hold reserves. Without an alternative they must lend to banks at whatever rate banks offer. ON RRP gives them a risk-free option at a published rate, so they will not lend below it to anyone.

Take-up is a thermometer, not a policy setting. Large balances mean cash cannot find a better return in private markets; a decline usually means bill supply or repo rates have become more attractive.

The operation drains reserves without shrinking the Fed's balance sheet. Total liabilities are unchanged — the money simply moves from the reserves line to the reverse repo line, and only one of those is base money.

The mechanics

Direction of cash
From the fund to the Fed overnight; the Fed pledges Treasuries as collateral.
Effect on reserves
Down by the amount taken up, because the cash came out of a bank deposit.
Effect on the Fed's sheet
No change in size. Composition of liabilities shifts, nothing more.

The common misreading

That the Fed is 'printing money' when take-up rises. The opposite happens: ON RRP absorbs cash and shrinks the monetary base, even though the Fed's overall balance sheet stays exactly the same size.
