Secured Overnight Financing Rate (SOFR)
SOFR is the benchmark overnight repo rate that replaced LIBOR as the primary reference rate for US dollar-denominated financial contracts, calculated daily from Treasury repo transaction volumes.
The macro regime is unambiguously STAGFLATION DEEPENING. The hot CPI print (pending event, 24h ago) is not a surprise — it is a CONFIRMATION of the pipeline signals that have been building for weeks: PPI accelerating faster than CPI, Cleveland nowcast at 5.28%, breakevens rising +10bp 1M across the …
What Is SOFR?
The Secured Overnight Financing Rate (SOFR) is the benchmark overnight repo rate for US dollar-denominated financial contracts. It is calculated daily by the Federal Reserve Bank of New York from actual transaction data in the Treasury repo market, where dealers and money funds lend and borrow overnight against Treasury collateral.
SOFR replaced LIBOR as the primary USD reference rate following the 2008-2012 LIBOR manipulation scandal. The transition was completed by June 2023, when LIBOR ceased publication for major tenors. SOFR is the FRED ticker SOFR.
Why It Matters for Markets
SOFR is the reference rate for trillions of dollars of derivatives, floating-rate loans, mortgages, and securitisations. Every SOFR fixing flows into the pricing of these contracts. Daily SOFR levels also signal the health of money markets — persistent deviations from the Fed funds target range indicate plumbing stress.
The 1-month, 3-month, 6-month, and 12-month forward SOFR rates (derived from SOFR futures) are the primary inputs for Fed policy-path pricing. SOFR-OIS swap rates and SOFR futures are the cleanest read on near-term FOMC decisions.
How to Read the Print
SOFR vs Fed funds target range. SOFR should trade within the Fed funds target range (with IORB as the ceiling, ON RRP rate as the floor). Deviations above the target signal liquidity scarcity; deviations toward the floor signal liquidity abundance.
Daily SOFR volatility. Quarter-end spikes (typically 5-15 bp above the Fed funds target on the last day of March, June, September, December) are normal as bank balance sheets contract. Larger spikes signal stress.
SOFR vs Fed funds (IORB) spread. The SOFR-IORB spread reveals whether reserve balances are scarce or abundant. Negative spreads (SOFR below IORB) signal abundant reserves; positive spreads signal scarcity. The Fed monitors this spread for QT calibration.
Historical Context
SOFR was first published in April 2018. Through normal market conditions, daily SOFR has tracked within 1-2 bp of the Fed funds target range midpoint. The September 17, 2019 repo crisis pushed SOFR to 5.25% with Fed funds at 2.25%, the largest single-day deviation in the data series.
Through 2024-2025, SOFR has traded in the 3.50-3.75% range alongside the Fed's post-September-2024 rate-cut cycle. Quarter-end spikes have been modest (5-15 bp above the target) reflecting still-abundant reserve balances. A sustained breakout above the target range or above IORB would be the first sign that QT has approached reserve-scarcity thresholds.
