SOFR vs 10Y Treasury Yield

SOFR (Secured Overnight Financing Rate) is the volume-weighted median of overnight Treasury repo transactions, the cleanest market-implied overnight risk-free rate. April 2026: SOFR approximately 3.62 percent, daily volume approximately $2 trillion. SOFR is anchored to Fed policy through the Standing Repo Facility (cap) and Reverse Repo Facility (floor).

DGS10 (10-year Treasury yield) is the yield-to-maturity on the 10-year nominal Treasury bond, the global benchmark long-end risk-free rate. April 2026: 4.31 percent. The pair captures the slope of the entire risk-free curve from overnight to 10 years. Spread of plus 69 basis points reflects positive normal-shaped curve. Spread inversion (SOFR above 10Y) historically signals recession risk within 12 to 18 months, although the 2022 to 2024 episode was a 26-month false positive.

The SOFR-10Y spread is the cleanest curve trade in post-LIBOR rates because both legs are volume-anchored (SOFR $2 trillion daily, 10Y Treasury auctions $20 to $40 billion typical sizes). The spread captures three macro variables: expected fed funds path over 10 years (averages to approximately 3.5 percent), 10-year inflation expectations (breakeven 2.44 percent), and 10-year term premium (approximately 70 basis points).

Mathematics: 10Y yield equals expected average fed funds plus term premium plus inflation risk premium minus convexity adjustment. April 2026 decomposition: 4.31 percent equals 3.50 percent expected average fed funds plus 0.70 percent term premium plus small premium adjustments. SOFR 3.62 percent reflects current effective fed funds plus tiny credit risk component. The 69bp spread therefore represents the sum of expected Fed easing path plus term premium minus inflation pricing.

A 100 basis point parallel rise in rates has very different effects on SOFR and 10Y. SOFR resets daily at the new overnight rate (approximately zero duration). 10Y Treasury duration is approximately 9 years (price sensitivity), so a 100 basis point yield rise produces approximately 9 percent decline in a 10Y bond price.

This duration mismatch dominates trading. Positions long the spread (long 10Y duration plus short SOFR funding) profit from curve flattening (10Y yield falls faster than SOFR rises). Positions short the spread (short 10Y duration plus long SOFR funding) profit from steepening. The spread is the cleanest representation of the curve in liquid instruments and is a primary input to many recession-probability models including the NY Fed model (which uses the 10Y-3M spread, similar in spirit).

The 2022 to 2024 yield curve inversion was the deepest since 1981. The 10Y-2Y spread peaked inverted at minus 110 basis points in July 2023; the 10Y-3M spread peaked at minus 188 basis points; the 10Y-SOFR spread peaked at approximately minus 130 basis points in October 2023 when SOFR was 5.40 percent and 10Y was 4.10 percent.

The inversion lasted 26 consecutive months (July 2022 to August 2024), the longest in modern history. Traditional yield curve recession signal completely failed: no recession materialized despite the deepest inversion since Volcker. The episode produced the longest false-positive yield curve signal in 50-plus years, a key reason analysts now treat yield curve inversion with more skepticism. The 10Y-SOFR pair captured this episode cleanly, providing the cleanest single-pair representation of the post-LIBOR curve story.

The Fed cut 100 basis points from September 2024 to December 2024, taking SOFR from 5.40 percent (September 2024) to 3.62 percent (April 2026), a 178 basis point compression. 10Y yield moved from 3.85 percent (September 2024 trough) to 4.31 percent (April 2026), a 46 basis point rise reflecting term premium reconstitution.

The 10Y-SOFR spread expanded from minus 130 basis points (October 2023) to plus 69 basis points (April 2026), a 199 basis point swing. This is a textbook bull-steepener pattern: front-end falls faster than long-end as Fed cuts, and term premium rebuilds as the curve normalizes. Markets currently price 50 to 75 basis points of additional Fed cuts through 2026, which would extend the steepener if realized.

2008 to 2009 GFC (using fed funds as SOFR proxy before SOFR launch in 2018): Fed funds collapsed from 5.25 percent to 0.25 percent in 16 months, while 10Y yield fell from 5.00 percent to 2.00 percent. Spread expanded from minus 25 basis points to plus 175 basis points (200 basis point swing).

2020 COVID: SOFR (launched 2018) collapsed from 1.55 percent (February 2020) to 0.05 percent (April 2020). 10Y fell from 1.60 percent to 0.55 percent. Spread expanded from plus 5bp to plus 50bp. Then 2021 to 2022 reflation moved SOFR from 0.05 percent to 4.30 percent (430 basis point hike) while 10Y rose from 0.55 percent to 4.10 percent. Spread compressed from plus 50bp to plus 0bp by mid-2022, then inverted to peak minus 130bp in October 2023. 2024 to 2026 reversed the dynamic with current plus 69bp.

SOFR is fully anchored to Fed policy through the SRF and RRP corridor system. SOFR-EFFR correlation is approximately 0.99 daily. The Fed effectively determines SOFR through the corridor.

10Y is determined by markets through expected fed funds path (3.50 percent component) plus term premium (70 basis point component) plus inflation expectations component. Term premium has been rising structurally since 2020 (from negative 50 basis points in 2018 to 2019 to positive 70 basis points in 2024 to 2026). Drivers include foreign Treasury holdings declining 36 percent to 23 percent of total Treasury market 2014 to 2025, Fed QT removing the marginal long-duration buyer, and US fiscal trajectory concerns ($2 trillion annual deficits, debt-to-GDP approaching 130 percent).

Setup 1 (40 percent probability): Continued bull steepener. Fed cuts 50 to 75 basis points through 2026, SOFR drops to 2.85 to 3.10 percent, 10Y stable 4.20 to 4.40 percent. Spread expands to 110 to 155bp. Trade: long 10Y duration plus short SOFR funding.

Setup 2 (25 percent): Recession bull flattener. Fed cuts to 2.00 percent, SOFR drops to 2.00 percent, 10Y falls to 3.00 percent. Spread expands modestly to 100bp but both ETFs rally substantially. Trade: long 10Y duration broadly. Setup 3 (20 percent): Sticky inflation, term premium rises. SOFR holds at 3.62 percent, 10Y rises to 4.80 percent on bear steepener. Spread expands to 118bp on different mechanism. Trade: short 10Y duration, neutral SOFR. Setup 4 (15 percent): Stagflation. Fed forced to hike, SOFR rises to 4.50 percent, 10Y rises to 5.50 percent. Spread compresses to 100bp on bear flattener. Trade: short SOFR aggressively, short 10Y modestly.

Basic dashboard: track SOFR-10Y spread alongside 10Y-2Y and 10Y-3M for cross-validation. April 2026: SOFR 3.62 percent, 10Y 4.31 percent, spread plus 69bp.

Three rules. First, spread inversion sustained more than 30 days historically signals recession risk within 12 to 18 months (though 2022 to 2024 was a 26-month false positive). Second, spread above 200bp historically marks late-stage easing or recession dynamics with both legs at low absolute levels. Third, sustained spread in 50 to 100bp range is mid-cycle re-steepening territory, suggesting balanced positioning with modest cyclical bias. The current 69bp reading sits in the middle of the historical range and reflects the post-cycle re-steepening regime now in its fifth quarter.

SOFR futures (CME, ticker SR3) have replaced Eurodollar futures as the primary front-end rate hedging vehicle. CME daily volume in SOFR futures exceeds $2 trillion notional. 10Y Treasury futures (CME, ticker ZN) have daily volume of approximately $200 billion notional.

The SOFR-10Y curve trade is one of the most-traded macro trades in fixed income. Common implementations: 1x SOFR futures vs 0.13x ZN (10Y) futures (DV01-matched), or simple 1:1 ratio for directional view. The curve has roughly 300 basis points of total range historically (from minus 130bp peak inversion to plus 175bp peak steepener). Current 69bp sits in the middle. Position sizing should account for the asymmetry: tail risk from acute crisis re-pricing is higher than typical realized volatility, particularly when the Fed pivots between hiking and easing cycles.
