What Happens When SOFR Spikes Above Fed Funds?
SOFR spikes signal acute funding stress in Treasury repo markets. What happens when overnight funding rates rise above the Fed target?
Trigger: SOFR spikes more than 20 bps above fed funds
The Mechanics
SOFR (Secured Overnight Financing Rate) is the benchmark overnight rate for Treasury-collateralized repo markets. It replaced LIBOR as the primary USD funding benchmark. Under normal conditions, SOFR trades within a few basis points of the Fed's target range, anchored by the interest rate on reserves (IORB) at the top and the reverse repo facility (ONRRP) at the bottom.
SOFR spikes above fed funds signal acute stress in the Treasury-collateralized funding market. Such spikes usually reflect a mismatch between reserves (the Fed's liability to banks) and demand for overnight financing. Drivers include quarter-end balance-sheet constraints, Treasury auction settlements that drain reserves, tax-date cash outflows, and structural balance-sheet pressures from quantitative tightening.
The 2019 repo spike is the canonical example: SOFR jumped from 2.2% to 5.3% in a single day on September 17, 2019. The Fed responded with emergency repo operations and resumed balance-sheet expansion within weeks. The episode revealed that the "ample reserves" framework had an unidentified lower bound that QT was approaching.
Historical Context
SOFR has existed since 2018. The September 2019 spike (SOFR to 5.3%, roughly 300 bps above fed funds) was the most severe funding disruption in the post-2008 era. Drivers included corporate tax payments draining cash, Treasury auction settlements absorbing reserves, and structural reserve scarcity from QT. The Fed responded with overnight repo operations totaling $75 billion, eventually expanding to $120 billion, and announced resumption of balance-sheet growth within weeks. Other SOFR stress episodes include March 2020 (COVID dollar shortage, Fed response with unlimited repo and swap lines), and late 2018 quarter-end. The Standing Repo Facility, established in 2021, was designed to prevent repeat of 2019-style episodes by providing elastic overnight Treasury repo at a pre-announced rate.
Market Impact
The Fed almost always responds to SOFR spikes with liquidity-providing operations. 2019 saw emergency repo operations; 2020 saw unlimited repo. Structural responses include balance-sheet expansion or slowing of QT.
WALCL typically expands following sustained SOFR stress. The 2019 episode directly triggered the "not-QE" Treasury bill purchases that restarted balance-sheet growth.
RRP balances often fall sharply as money-market funds deploy cash into repo at attractive rates above ONRRP. This reallocation shifts Fed liabilities from RRP to bank reserves, easing pressure.
Acute SOFR stress often coincides with dollar strength as global dollar shortage builds. The March 2020 episode saw DXY rally from 94 to 103 in two weeks before Fed swap-line expansion reversed it.
Sustained SOFR stress typically tightens overall financial conditions and pressures risk assets. Brief quarter-end spikes have minimal spillover, but persistent stress signals liquidity shortage and equity selloffs.
Bond yields typically rise initially as funding costs squeeze leveraged positions (basis trades) and force selling. Once Fed liquidity response begins, yields fall as QE-style operations resume.
What to Watch For
- -Bank reserves (WRESBAL) declining toward $3 trillion or below
- -Reverse repo (RRP) balances approaching zero
- -Quarter-end dates (March, June, September, December) for periodic stress
- -Treasury auction settlement dates draining reserves
- -Standing Repo Facility usage increasing (Fed intervention signal)
How to Interpret Current Conditions
Track SOFR daily against the fed funds target range. Compare against ONRRP balances, bank reserves (WRESBAL), and the Treasury General Account (WTREGEN). Rising reserves and falling RRP indicate elastic supply of repo financing. Falling reserves alongside rising SOFR signal approaching a funding-stress inflection point.

Frequently Asked Questions
What triggers the "SOFR Spikes Above Fed Funds" scenario?▾
The scenario activates when spikes more than 20 bps above fed funds. 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: Federal Reserve, Fed Balance Sheet (WALCL), Reverse Repo (RRP), Dollar (DXY). 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?▾
SOFR has existed since 2018. The September 2019 spike (SOFR to 5.3%, roughly 300 bps above fed funds) was the most severe funding disruption in the post-2008 era. Drivers included corporate tax payments draining cash, Treasury auction settlements absorbing reserves, and structural reserve scarcity from QT. The Fed responded with overnight repo operations totaling $75 billion, eventually expanding to $120 billion, and announced resumption of balance-sheet growth within weeks. Other SOFR stress episodes include March 2020 (COVID dollar shortage, Fed response with unlimited repo and swap lines), and late 2018 quarter-end. The Standing Repo Facility, established in 2021, was designed to prevent repeat of 2019-style episodes by providing elastic overnight Treasury repo at a pre-announced rate.
What should I watch for next?▾
The most important signals to track while this scenario is active: Bank reserves (WRESBAL) declining toward $3 trillion or below; Reverse repo (RRP) balances approaching zero. 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 SOFR daily against the fed funds target range. Compare against ONRRP balances, bank reserves (WRESBAL), and the Treasury General Account (WTREGEN). Rising reserves and falling RRP indicate elastic supply of repo financing. Falling reserves alongside rising SOFR signal approaching a funding-stress inflection point.
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.
