The probability of a Federal Reserve interest rate hike at the September 16 FOMC meeting has climbed to approximately 65 to 68 percent as of September 1, more than doubling from roughly 36 percent before Fed Chair Kevin Warsh delivered his keynote address at the Jackson Hole Economic Policy Symposium on August 28. The CME Group’s FedWatch Tool, which derives implied policy odds from federal funds futures trading, now prices a 25-basis-point increase to a target range of 3.75 to 4.00 percent as the most likely outcome. The shift followed Warsh’s explicit recommitment to the Fed’s 2 percent inflation target and his characterization of current price data as “concerning,” language that markets interpreted as a signal that the central bank is prepared to tighten policy if incoming data does not show meaningful improvement before the September decision.
Key Takeaways
- The CME FedWatch Tool places September rate hike odds at approximately 65 to 68 percent as of September 1, up from roughly 36 percent on August 21 and 40 percent just one week before Warsh’s speech.
- Fed Chair Kevin Warsh cited headline PCE inflation at 3.7 percent and the six-month PCE change at 4.1 percent in his Jackson Hole address, calling both figures “concerning” and stating that the Fed has “work to do.”
- Core PCE inflation has held at 3.3 percent for four consecutive months (April through July), producing almost no net improvement toward the Fed’s 2 percent target.
- Barclays now anticipates two rate hikes this year, in September and December, totaling 50 basis points, which would raise the federal funds rate target range to 4.00 to 4.25 percent.
- The 10-year Treasury yield rose to approximately 4.77 to 4.79 percent on September 1, its highest level since January 2025; the 30-year yield has spent 55 days above 5 percent in 2026, the most since 2006.
- July JOLTS job openings data and August ISM Manufacturing PMI were both scheduled for September 1 release at 10:00 a.m. ET, with the September 5 nonfarm payrolls report and early September CPI data completing the pre-decision data window.
Warsh’s Jackson Hole Speech Broke With His Own July Ambiguity
The market reaction to Warsh’s August 28 address was as much about contrast as content. Warsh’s first two news conferences as Fed chairman, following the May and July FOMC meetings, left traders uncertain about his policy direction. Multiple analysts described his July remarks as “word salad,” and the lack of clarity contributed to a bond market sell-off as investors added a risk premium to account for the unpredictability of the new chairman’s communication style. The August 28 speech, delivered on Warsh’s 100th day as Fed chairman, was a deliberate correction.
Warsh used the Jackson Hole platform to deliver three points that the market read as sequentially hawkish. First, he cited specific inflation figures rather than speaking in generalities. The 12-month PCE price index at 3.7 percent and the six-month change at 4.1 percent were presented as data points that demand a policy response, not background context. Second, he recommitted to the 2 percent PCE inflation target without qualifying language, stating that “market prices show confidence that we will deliver price stability” and framing that confidence as something the Fed must validate through action. Third, he described financial conditions as “not broadly restrictive,” a shift from his July characterization of conditions as “uneven.” That distinction matters because it removes a potential argument against tightening: if conditions are not yet restrictive, the current rate level may be insufficient to bring inflation back to target.
Warsh also pushed back on critics of his communication approach, stating that the Fed “can be held accountable for delivering on our remit” and dismissing calls for more explicit forward guidance. His formulation, “I stand here today committed to a discipline, not to a decision,” preserved deliberate ambiguity about the September outcome while making the inflation mandate unmistakable. The market interpreted the combination as a chairman who is willing to hike but unwilling to pre-announce the timing, which in practice means the data between now and September 16 will determine whether the probability converts into action.
The Data Window Between Jackson Hole and September 16 Is Narrow and Consequential
Five business days of economic data releases separate the Jackson Hole speech from the September 16 FOMC decision, and each report now carries outsized weight because of the near-even probability split. The July JOLTS job openings report and August ISM Manufacturing PMI were both released on September 1, providing the first post-Jackson Hole reads on labor market demand and manufacturing activity. The September 5 nonfarm payrolls report follows, delivering the employment data that the Fed historically weighs heavily in rate decisions. An early September CPI release will provide the most recent consumer price reading before the meeting.
The sequence matters because Warsh explicitly declined to identify which data points would trigger a hike. Unlike his predecessor, who used dot plots and forward guidance to telegraph rate moves months in advance, Warsh has rejected what he views as the Fed’s over-reliance on managing market expectations. The result is a decision framework where each data point functions less as an input to a known formula and more as evidence in an argument that the committee will resolve internally. For market participants, this means the payrolls and CPI reports will produce immediate repricing in the FedWatch probabilities, with little cushion from advance guidance about how the Fed will weight the numbers.
The July PCE data released on August 26 set the baseline for this window. Headline PCE inflation came in at 3.7 percent year-over-year, 0.1 percentage point above the Dow Jones consensus. Core PCE matched forecasts at 3.3 percent. Month-over-month, both measures rose 0.2 percent. The personal saving rate edged up to 3.0 percent from 2.6 percent in June, while real consumer spending was essentially flat, rising less than 0.1 percent. Personal income grew 0.4 percent, outpacing the 0.2 percent increase in nominal spending. The data shows an economy where consumers are still spending but decelerating, income is growing faster than expenditures, and inflation remains stubbornly above target with no meaningful downward trajectory across the last four months.
The Bond Market Has Already Priced a Tightening Trajectory
While the equity market debate centers on whether the Fed will hike or hold, the bond market has moved with less ambiguity. The 10-year Treasury yield rose to approximately 4.77 to 4.79 percent on September 1, its highest level since January 15, 2025. The 30-year Treasury yield climbed to 5.24 to 5.30 percent, and the long bond has now spent 55 days above 5 percent in 2026, the most in any calendar year since 2006. The global dimension of the sell-off underscores that the repricing is not confined to U.S. policy expectations. Japan’s 10-year government bond yield reached 3 percent for the first time since 1996. Germany’s benchmark yield rose to a level not seen since 2011. UK yields broadened the move higher.
Ross Mayfield, investment strategist at Baird, noted that stocks will “always and forever struggle to digest big and kind of volatile moves in the bond market,” framing the yield pressure as a structural headwind rather than a one-week event. Daniela Hathorn, senior market analyst at Capital.com, identified three forces sustaining the elevated yield environment: heavy government borrowing, an elevated term premium, and growing competition for capital across global bond markets. Those forces operate independently of the September rate decision, meaning that even a Fed hold may not produce meaningful relief in long-term borrowing costs.
The downstream implications for borrowers are already visible. The Freddie Mac 30-year fixed mortgage rate stood at 6.66 percent as of August 27, near two-decade highs. A 25-basis-point hike would not directly move the 30-year fixed rate, which tracks the 10-year Treasury more closely than the federal funds rate, but it would signal that the Fed prioritizes inflation control over growth support, potentially pushing long-term yields higher if the market reads the hike as the beginning of a sequence rather than a one-off adjustment.
Wall Street Is Split on Whether September Is the Meeting
The disagreement between futures markets and prediction platforms illustrates the genuine uncertainty surrounding the September decision. CME FedWatch, derived from institutional futures trading, places hike odds at 65 to 68 percent. Prediction markets Polymarket and Kalshi, which aggregate individual bettor positioning, narrowly price a hold at 52 percent. The divergence means that how the probability is measured changes the base case, an unusual condition for a rate decision less than two weeks away.
Barclays has taken a firm position, forecasting two rate hikes this year, in September and December, totaling 50 basis points. That would lift the federal funds rate target range from the current 3.50 to 3.75 percent to 4.00 to 4.25 percent by year-end. The forecast reflects Barclays’ read that Warsh’s Jackson Hole rhetoric was not performative but directional, and that the stickiness of core PCE at 3.3 percent across four months provides the data justification for action.
Not all analysts agree that September is the inflection point. Heather Long, chief economist at Navy Federal Credit Union, said Warsh “opened the door to a Fed rate hike” but predicted the action would more likely come in October or December. Her reasoning centers on the limited data available before September 16 and the Fed’s institutional preference for acting on a fuller information set. A September hold followed by a hike later in the fall would allow the committee to incorporate August employment data, September CPI, and additional signals about whether the consumer spending deceleration visible in the July PCE report is deepening or reversing.
The equity market’s response reflects the uncertainty. The S&P 500 closed at 7,631 on September 1, down 0.71 percent. The Nasdaq Composite fell 1.03 percent to 26,100, with the technology sector bearing the largest decline as rate-sensitive growth stocks repriced. The Dow dropped 419 points, or 0.79 percent, to 52,767. Gold declined 1.62 percent to $4,409. The sell-off was orderly rather than panicked, suggesting that institutional positioning is adjusting to the new probability landscape rather than fleeing risk assets entirely.
What the September Decision Means for Business Owners and Borrowers
For entrepreneurs and small business operators tracking borrowing costs, the practical calculation has shifted. A 25-basis-point hike would raise the prime rate, which directly affects variable-rate business loans, SBA loan products tied to prime, and commercial lines of credit. Businesses carrying variable-rate debt would see immediate cost increases on existing balances. Those planning to draw on revolving credit facilities or negotiate new loan terms face a decision window measured in days rather than weeks.
The mortgage market presents a parallel consideration. The 30-year fixed rate at 6.66 percent already reflects the bond market’s anticipation of tighter policy. A hike that the market has largely priced in may not produce a significant additional move in fixed mortgage rates. However, a hike accompanied by hawkish dot-plot projections or a statement suggesting further tightening ahead could push the 10-year yield above 5 percent, dragging fixed mortgage rates toward 7 percent and further constraining housing affordability and residential investment activity.
The five-day data window ahead of September 16 will determine whether the 66 percent probability holds, rises, or reverses. A strong payrolls report on September 5 would reinforce the case for a hike by demonstrating that the labor market can absorb tighter policy. A weak report would give Fed officials cover to wait. For businesses and investors, the actionable signal is not the probability itself but the direction it moves after each data release. The September FOMC meeting is no longer a background event. It is the central variable in the near-term cost of capital for every borrower in the United States.

FAQs
What Are the Current Odds of a Fed Rate Hike in September 2026?
As of September 1, the CME FedWatch Tool places the probability of a 25-basis-point rate hike at the September 16 FOMC meeting at approximately 65 to 68 percent. Prediction markets Polymarket and Kalshi price a hold at roughly 52 percent. The probabilities shifted sharply after Fed Chair Kevin Warsh’s hawkish Jackson Hole speech on August 28.
What Did Fed Chair Warsh Say at Jackson Hole?
Warsh cited headline PCE inflation at 3.7 percent and the six-month PCE change at 4.1 percent, calling both “concerning.” He recommitted to the Fed’s 2 percent inflation target, described financial conditions as “not broadly restrictive,” and stated the Fed has “work to do.” He declined to pre-commit to a specific September action, saying he was “committed to a discipline, not to a decision.”
What Is the Current Federal Funds Rate?
The federal funds rate target range is currently 3.50 to 3.75 percent. A 25-basis-point hike in September would raise it to 3.75 to 4.00 percent. Barclays forecasts two hikes this year (September and December) that would bring the range to 4.00 to 4.25 percent by year-end.
How Would a Rate Hike Affect Mortgage Rates?
The 30-year fixed mortgage rate stood at 6.66 percent as of August 27, according to Freddie Mac. A rate hike would not directly move the 30-year fixed rate, which tracks the 10-year Treasury yield more closely than the federal funds rate. However, a hawkish Fed statement suggesting further hikes could push long-term yields higher, potentially dragging fixed mortgage rates toward 7 percent.
What Economic Data Is Released Before the September 16 Decision?
Key releases include July JOLTS job openings and August ISM Manufacturing PMI (September 1), the September 5 nonfarm payrolls report, and an early September CPI release. The next PCE inflation report covering August data is not scheduled until September 30, after the FOMC decision. Each report will likely produce immediate moves in FedWatch probabilities given the near-even split in market expectations.
