Warsh's First Real Test: Why the 10-Year, Not the Funds Rate, Decides 16 September

By Ruslan Averin · RFC Capital Research

Fed decision 16 September 2026: a quarter-point hike to 3.75–4.00% is 91 to 93% priced, the 10-year sits near 5%, and three scenarios split the long end.

Warsh's First Real Test: Why the 10-Year, Not the Funds Rate, Decides 16 September — Ruslan Averin, RFC Capital Research
Analysis: Ruslan Averin · RFC Capital Research

Thirty-three basis points contain the entire argument

The 2-year Treasury trades at 4.66% and the 10-year at 4.99%. That gap is the market's verdict in a single number: the Federal Reserve is expected to lift rates toward 4.5% and stop, and investors want a term premium stacked on top for the deficit and for oil. The decision lands at 14:00 ET.

For the first time since 26 July 2023, the expected verb is "raise". Futures price a quarter-point move to 3.75–4.00% at 91 to 93%, sixteen of twenty banks agree, and the 10-year spent Tuesday above 5% for the first time since July 2007. Kevin Warsh, chair since 22 May, meets a session where statement, dot plot and press conference all lean the same way.

The vote tally that explains the drift

The target range has been 3.50–3.75% since the cut of 10 December 2025. Five holds followed in 2026, and the ballots show the direction of travel: 10–2 in January, with Miran and Waller seeking a cut; 8–4 in April, the most dissents since 1992; 12–0 at Warsh's first meeting in June; then 9–3 in July, with Hammack, Kashkari and Logan voting to raise.

The July minutes recorded that "several" participants judged "policy tightening would likely be necessary if inflation did not decline". Inflation did not decline.

A supply shock the Committee is being asked to tighten into

June's projections assumed 2026 PCE inflation of 3.6%; July printed 3.7% year over year. Core PCE was pencilled at 3.3% and came in at 3.3%. August CPI ran 3.4% headline, up 0.4% month over month, while core fell to 2.4% year over year, up 0.3% monthly and the lowest reading since 2021. Unemployment is 4.1% against a 4.3% assumption, with payrolls up 162,000.

The wedge is energy. Energy CPI is up 16.3% year over year, gasoline up 27.4%, Brent settled at $108.75 on 15 September after a 20% September rally, and the Saudi East-West pipeline has been shut since 11 September without a restart date. Mark Cabana at Bank of America framed the choice as hiking "or risk a disorderly selloff at the long end".

The dot plot outranks the rate

June's median dot showed 3.8% for end-2026 and 3.6% for end-2027, with nine of eighteen participants already above the current range. The market sits far beyond that: 4.18% implied for December, roughly 56 basis points across the next three meetings, and a path toward 4.4–4.6% in 2027.

ScenarioProbabilityStatement and dots2-year10-yearDollar and gold

C. Hold~8%No change; hawkish trio dissents; statement promises action "if inflation does not decline"down sharplyup 10 basis points or more on credibilityDollar weaker; gold above $4,500; EUR/USD 1.165–1.17

The odds blend CME FedWatch, the Robinhood prediction market at 88 cents on a hike and 15 on a hold, and published bank calls; the market levels are the ranges FXEmpire set out on 15 September. Scenario B matches Robin Brooks of Brookings, who argued "there's no way he can live up to all the hikes priced, so the press conference will likely disappoint markets". Goldman sits there implicitly: a hike now, two cuts still pencilled for 2027.

The counter-intuitive part: hawkishness helps long bonds

For a mortgage borrower, a homebuilder or a holder of long paper, the funds rate is a rumour and the 10-year is the fact. Freddie Mac's weekly average was 6.76% on 10 September, while Mortgage News Daily's index ran 7.07%, 7.12%, 7.17% and 7.22% across the four sessions to Tuesday, the highest since January 2025.

Scenario A is the friendliest for duration: a Fed that raises and signals more shifts inflation premium out of the 10-year into the 2-year, the curve flattens and the 30-year at 5.36% attracts buyers. A hold does the damage. Joachim Schallmayer of Deka told Handelsblatt that "if the Fed does not act, uncertainty remains and long-term rates keep rising". Der Aktionär applies the same logic to the DAX, where reluctance steepens the curve and threatens 25,170 support.

In the view of analyst Ruslan Averin, the dovish surprise that would hurt long Treasuries is precisely the outcome the central bank has spent three weeks steering away from. Warsh at Jackson Hole: "We must be confident that underlying inflation is moving to our objective, clearly and at sufficient speed. Otherwise, we have work to do."

Where markets stood into the announcement

The DAX closed at 25,402 on Tuesday, opened higher and sat at 25,459 at midday, up 0.2%, with the Stoxx 600 up 0.4% for its first gain in three sessions. S&P 500 futures were up 0.2% at 7,675 after Tuesday's 7,585.73 close, a sixth loss in seven sessions; VIX 16.96.

The dollar index is 99.65, EUR/USD 1.1539 and below its 100-day average, USD/JPY touched 155.43 overnight. Gold trades at $4,339 spot, up 1.3% from a $4,291.60 settle, its three-week slide from $4,603 paused rather than reversed. Brent is $107.93 after the API reported a 7.1 million barrel US crude build; bitcoin is $75,800, down 1.5%.

The day is calm, the quarter is not

Since December 1999 the S&P 500 has averaged +0.23% on decision days and closed higher 52.6% of the time, with an average absolute move near 2% against 1.25%

How likely is a rate hike at the 16 September 2026 meeting?
Futures price a quarter-point move to 3.75–4.00% at 91 to 93%, sixteen of twenty banks call it, and the Robinhood prediction market shows 88 cents on a hike against 15 on a hold.
Why would the Fed tighten while core inflation is falling?
Core CPI is 2.4% year over year, the lowest since 2021, but headline is stuck at 3.4% on energy, with energy CPI up 16.3% and gasoline up 27.4%. The bond market treats 3.50–3.75% as insufficiently restrictive.
Which scenario is worst for long-dated Treasuries?
A hold. The 2-year would rally, but the 10-year sells off 10 basis points or more on credibility concerns, with gold above $4,500 and EUR/USD at 1.165–1.17.
What else moves markets this week?
NAHB at 10:00 ET, Lennar after the close with consensus EPS of $1.30, housing starts Thursday, the Bank of England at 3.75%, the Bank of Japan at 1.00% and the National Bank of Ukraine at 15.5%.
