US stock indexes slipped on Wednesday as Treasury yields rose and Brent crude climbed above $105 a barrel, but the bigger test lands today: the August consumer price report, the last major release before the Federal Reserve meets on September 15 and 16.
Futures markets currently price roughly a 70% chance that the Fed raises its benchmark by a quarter point at the meeting, up sharply from where those odds stood a month ago. The repricing tracks two inputs: a string of hot inflation prints and an oil market upended by the war involving Iran, which has pushed crude from below $90 to $105 in a matter of weeks. Energy costs feed into headline inflation with a lag, and traders assume the August report will start to show it. Gasoline prices at the pump have already climbed in recent weeks, and airline and freight surcharges tend to follow crude with a gap of one to two months, so the pipeline effect extends beyond the single print.
Wednesday’s producer price data added to the anxiety. Input costs rose 0.4% in August, hotter than forecast, and spot gold fell more than 1% as real yields climbed. When PPI surprises to the upside, economists treat it as a rough guide to the pipeline pressures that can surface later in consumer prices, and bond desks positioned accordingly. Two-year Treasury yields, the most sensitive to Fed expectations, have climbed alongside the hike odds, and the curve has flattened as short rates catch up to long ones.
A crowded central bank calendar
The Fed is not acting alone. The European Central Bank raised its deposit rate a quarter point to 2.25% on Wednesday, becoming the first major central bank to hike in direct response to the oil shock. ECB officials had leaned hawkish for weeks before the decision, warning that energy-driven inflation could unmoor wage expectations if left unanswered, and the governing council delivered without splitting its vote. The Bank of Japan meets September 18, with markets attaching roughly a 75% chance to a quarter-point rise there, and the Bank of England also decides next week. Japan’s case is the more delicate one: Governor Kazuo Ueda has hinted at normalization after years of ultra-loose policy, and a hike would push the 2-year JGB yield further past its multi-decade highs, tightening funding conditions across Asia in the process.
| Central bank | Meeting | Market expectation |
|---|---|---|
| ECB | September 10 | Hiked 25bp to 2.25%, delivered |
| Fed | September 15-16 | About 70% chance of a 25bp hike |
| Bank of Japan | September 18 | About 75% chance of a 25bp hike |
| Bank of England | Next week | Closely watched after ECB move |
Global bond markets have absorbed the shift. Yields across advanced economies have pushed to their highest levels of the cycle, with the 10-year Treasury trading near levels last seen before the 2008 financial crisis and European equivalents close behind. The next psychological marker for the US 10-year sits at 5.00%, a level that traded only briefly in late 2023 before this month’s move.
Currency markets tell the same story from a different angle. The yen has rallied as Bank of Japan tightening expectations build, which squeezes the global carry trade that borrowed in yen to fund positions elsewhere. A sustained yen rally forces those positions to unwind, and that dynamic helped knock bitcoin under $79,000 earlier this week alongside risk assets generally.
What the CPI report decides
Economists expect headline inflation to firm as energy passes through, while core readings matter more for the Fed. Chair Kevin Warsh has signaled that the committee will move if inflation does not cool, and governor Michael Barr has said he would support a hike without further improvement. The dissent-free path to a September hike runs through a core number that comes in at or above forecast. Economists expect core CPI to hold near its recent pace once the volatile food and energy components are stripped out, and shelter costs remain the stubborn line item that keeps the core elevated. A softer shelter reading is the one plausible surprise that could knock the hike odds back down before the meeting.
For households and companies the stakes are concrete. Mortgage rates track the 10-year yield, so every leg higher in the bond market flows into housing costs within weeks. Emerging market borrowers face dollar funding costs that rise with the Fed’s path, and the euro area’s own hike on Wednesday showed that the tightening is not just an American affair. Several emerging market central banks have already moved pre-emptively, and the World Bank has warned that a broad tightening cycle arriving alongside an oil shock would hit importers hardest.
The oil premium is the wildcard in either direction. If diplomatic channels with Iran open and Brent retreats toward $90, the inflation scare loses its main driver and the hike odds deflate quickly. If the Strait of Hormuz situation worsens, $105 crude becomes a waypoint rather than a peak, and central banks will face a stagflationary mix of rising prices and slowing growth that leaves no comfortable option.
Equity positioning reflects the tension. The S&P 500 has held within a narrow band through the oil spike, supported by strong corporate earnings, but strategists at several banks argue the market is underpricing a hawkish surprise. If the Fed hikes while oil sits above $105, the combination of tighter money and higher energy costs compresses the valuation multiples that carried stocks to their recent records. Defensive sectors have quietly outperformed since the crude rally began, which suggests some managers are already repositioning.
Today’s report will not settle the war, but it will decide the tone of the most consequential Fed meeting of the year. Markets want a number, and by this afternoon they will have one.
