What Happens When the Fed Reverse Repo Facility Drains to Zero?
What happens when the Fed RRP facility drains? Liquidity implications, money market dynamics, and impact on bank reserves.
Trigger: Overnight Reverse Repo declines below $100B
The Mechanics
The Fed's overnight reverse repo (RRP) facility allows money market funds and other eligible counterparties to deposit cash with the Fed at the administered rate, earning a risk-free return. RRP balances peaked at $2.5T in late 2022 as excess liquidity accumulated in money markets post-COVID stimulus. As these balances drain, funds flow back into T-bills, repo, and bank deposits, with important implications for liquidity.
When RRP drains to zero, the money market transition is largely complete: excess cash has been redeployed into higher-yielding short-term debt. This removes the liquidity "buffer" that has absorbed Treasury issuance and Fed QT without pressuring bank reserves. Further Treasury issuance or QT then directly reduces reserves, potentially triggering stress.
The 2019 repo spike occurred when bank reserves declined below a critical threshold. A fully drained RRP combined with continued QT raises the risk of reserves falling below minimum comfortable levels, potentially forcing the Fed to end or reverse QT.
Historical Context
RRP balances ranged from $0-$400B before 2021, spiked to $2.5T in late 2022, and began draining in 2023 as T-bill supply expanded and rates rose. By early 2024, balances had declined to roughly $400B, freeing liquidity for Treasury absorption. Similar dynamics in 2018-2019 saw reserves drain aggressively, culminating in the September 2019 repo spike that forced the Fed to restart balance sheet expansion.
Market Impact
Draining RRP has historically supported risk assets by recirculating liquidity into markets.
T-bill yields decline as money fund demand increases. Bill-OIS spread narrows.
Reserves become more vulnerable once RRP cushion is exhausted. Repo rate volatility may rise.
Mixed. Near-term liquidity support positive, but Fed being forced to end QT could be positive longer-term.
Banks benefit from stable deposit environment but vulnerable if repo stress emerges.
Dollar typically neutral to slightly negative as excess dollar liquidity recirculates.
What to Watch For
- -RRP balance below $200B
- -Bank reserves declining below $3T
- -SOFR-IORB spread widening
- -Treasury bill supply continuing to expand
- -Fed statements signaling possible QT adjustment
How to Interpret Current Conditions
Track RRP alongside bank reserves (WRESBAL) and TGA balance (WTREGEN). The interplay determines whether total liquidity is rising or falling.

Frequently Asked Questions
What triggers the "the Fed Reverse Repo Facility Drains to Zero" scenario?▾
The scenario activates when declines below $100B. The trigger metric and its current reading are shown on this page, so the live state of the scenario is always visible rather than abstract. Convex tracks this trigger continuously and flags crossings within hours.
Which assets are most affected when this scenario unfolds?▾
The Market Impact section lists the full asset-by-asset response, but the primary affected assets include: Risk Assets (SPY, BTC), Treasury Bills, Bank Reserves, Long-Duration Treasury (TLT). Each asset has historically shown a characteristic pattern of response that is described in detail on the per-asset deep-dive pages linked below.
How often has this scenario played out historically?▾
RRP balances ranged from $0-$400B before 2021, spiked to $2.5T in late 2022, and began draining in 2023 as T-bill supply expanded and rates rose. By early 2024, balances had declined to roughly $400B, freeing liquidity for Treasury absorption. Similar dynamics in 2018-2019 saw reserves drain aggressively, culminating in the September 2019 repo spike that forced the Fed to restart balance sheet expansion.
What should I watch for next?▾
The most important signals to track while this scenario is active: RRP balance below $200B; Bank reserves declining below $3T. The full list is on this page under "What to Watch For." These signals are the ones that historically preceded the scenario either resolving or accelerating.
How should I interpret the current state of this scenario?▾
Track RRP alongside bank reserves (WRESBAL) and TGA balance (WTREGEN). The interplay determines whether total liquidity is rising or falling.
Is this a prediction or a conditional analysis?▾
This is conditional analysis, not a prediction that the scenario will happen. Convex describes what typically follows once the trigger fires and shows how close or far the current data is from that trigger. The page is informational; it does not constitute financial advice.
