What Is ON RRP?

What Is the Overnight Reverse Repo (ONRRP)?

The Overnight Reverse Repo facility is a tool operated by the New York Federal Reserve that allows eligible counterparties — primarily money market funds — to park excess cash at the Fed overnight in exchange for Treasury securities as collateral. The facility pays the ONRRP rate (currently in the 4.5-5.0% range) and serves as a floor for short-term interest rates.

From a liquidity perspective, ONRRP acts as a reservoir. When the ONRRP balance is high (it peaked at $2.55 trillion in December 2022), it means a massive amount of cash is parked at the Fed rather than flowing into the private financial system. When ONRRP drains, that cash moves into T-bills, bank deposits, repo markets, and eventually risk assets.

The Great ONRRP Drain of 2023-2024

Between January 2023 and early 2025, the ONRRP balance declined from over $2.2 trillion to roughly $100 billion — a drainage of more than $2 trillion. This was one of the most significant liquidity events of the decade, yet it received relatively little mainstream media attention.

The mechanism was straightforward: the Treasury issued large quantities of T-bills with yields above the ONRRP rate, incentivizing money market funds to move cash from the ONRRP facility into T-bills. This effectively transferred liquidity from the Fed back into the private sector.

During this period, the S&P 500 rallied approximately 35% and BTC went from $16,500 to over $70,000. That episode is why ONRRP cannot be reduced to one monotonic sign: the drain released cash into private markets, but it also consumed the buffer that later made QT and TGA rebuilds more binding.

How to Interpret ONRRP on DollarLiquidity.com

ONRRP is not read as a standalone level signal inside the DLI headline. It is subtracted inside the net-liquidity flow (Fed balance sheet - TGA - ON RRP): a falling balance releases liquidity, while a rising balance absorbs it.

This keeps a near-zero ONRRP balance from dominating the score after the release phase is over. Once ONRRP is low and flat, the primary liquidity levers are TGA, the Fed balance sheet, and direct funding-price signals such as SOFR-IORB and SRF usage. Track these together with TGA Balance, Fed BS Size, Net Liquidity.

Common Mistakes and Better Workflow

Mistake: Treating a depleted ONRRP balance as a permanent tightening input. Once the balance is near zero, the remaining flow impulse is small unless it starts rising again.

Better approach: Watch the ONRRP contribution inside net liquidity and confirm whether funding markets show pressure after the buffer is gone. If the balance is low and stable without SOFR-IORB or SRF stress, ONRRP should not dominate the score.
