Fed Opens September FOMC With 85% Hike Odds

The Federal Reserve begins its first rate-setting meeting since the December 2025 pause as futures price an 85% probability of a 25-basis-point increase in interest rates to a target range of 3.75-4.00%, with August PPI at 5.4%.

Lead

The Federal Open Market Committee convened its September two-day meeting Monday in Washington, reopening the rate-setting debate after a nine-month pause. Fed funds futures price an 85% probability of a 25-basis-point increase in the federal funds rate to a target range of 3.75-4.00%, the highest level since the prior tightening cycle. August producer price index data showing a 5.4% year-over-year gain and Brent crude trading above $107 a barrel have sharpened the case for renewed action. The rate decision and press conference are expected Tuesday afternoon, alongside the Federal Reserve's updated Summary of Economic Projections.

Why Are Interest Rates Rising Again?

The 85% probability reflects a sharp deterioration in the inflation outlook since the Fed signaled its pause last December. The August PPI print of +5.4% year-over-year came in well above consensus, driven by energy costs, transportation, and industrial inputs. Services inflation has remained sticky, and Brent crude above $107 - a level that historically transmits to consumer prices within two to three months - has erased the disinflationary progress logged earlier in 2026. Equity markets have repriced accordingly: SPY slipped roughly 1.3% over the five sessions preceding the meeting, and QQQ fell 1.8% as rate-sensitive growth valuations contracted.

What Does the Dot Plot Signal for 2026?

The September Summary of Economic Projections carries as much weight as the rate decision itself. The critical question is whether a majority of FOMC participants project a second 25-basis-point increase before December 31 - which would push the fed funds rate toward 4.00-4.25%. The December 2025 projections showed a divided committee that ultimately voted to hold; any consolidation toward a higher median projection would signal unusual unanimity on the inflation threat and reset the rate path sharply upward. A hawkish dot plot would also widen the spread between two-year Treasury yields, already at 4.62%, and longer-dated instruments, deepening the inversion that has persisted since February.

Energy and PPI: The Twin Drivers

Brent crude above $107 complicates the Federal Reserve's calculus in two ways. First, it directly pressures input costs for manufacturers and logistics operators, keeping PPI elevated. Second, it raises the risk that headline consumer inflation - which had been trending toward 3% - reverses course before year-end. NVDA, AMZN, and other large-cap technology and logistics names with heavy power and supply-chain cost exposure have underperformed as energy costs climbed. SOXL, the leveraged semiconductor ETF, dropped more than 4% in the week before the meeting as rate-sensitive growth stocks repriced. TSLA fell 2.8% Monday on rate and margin concerns.

Market Reaction Into the Meeting

MSFT and AAPL each declined roughly 1.5% Monday as rate sensitivity reasserted across the large-cap technology sector. The SCHD dividend ETF, a proxy for income-oriented equity strategies, fell 0.9% - a signal that higher short-term rates are reducing the relative attractiveness of dividend yields versus risk-free Treasuries. The two-year Treasury yield reached 4.62%, its highest since February, while the 10-year yield held near 4.35%. Regional bank stocks, exposed to net interest margin compression if the yield curve steepens rapidly, traded mixed.

What Comes Next for the Prime Rate?

If Tuesday's hike proceeds as futures anticipate, the prime rate - the commercial lending benchmark that moves in lockstep with the federal funds rate - would rise to 7.00%, the highest since 2007. Mortgage rates, already above 7%, would extend their climb. A second hike before December would push the prime rate to 7.25%, intensifying pressure on leveraged buyout activity, variable-rate commercial real estate debt, and consumer credit. Prime rate history shows that the last time this benchmark held above 7% for more than two consecutive quarters, housing transaction volumes fell by roughly 18% year-over-year.

Outlook

The September FOMC meeting marks a pivotal inflection point after nine months of policy stability. With August PPI at 5.4% year-over-year and Brent crude sustaining above $107, the conditions for a 25-basis-point hike to 3.75-4.00% are firmly in place. The dot plot will determine whether Tuesday's move is a one-off recalibration or the opening of a renewed tightening sequence. A hawkish projection cadence would put the prime rate at a multi-decade high before year-end and cement a higher-for-longer rate environment through at least the first quarter of 2027.
