Oil Holds Above $100 as Fed Rate Hike Bets Stay Firm on Energy Inflation
CME FedWatch put hike odds at 72.4% before the September meeting as Iran-driven crude stays above $100 and producer prices run at 5.4% year-on-year.
ICE Brent crude front-month slipped to $103.84 per barrel on Thursday (2026-09-17), down about 1% on the day, but the pullback has done little to ease pressure on Federal Reserve policymakers weighing their first rate decision since crude broke $100. CME FedWatch data showed, as of September 10 (2026-09-10), that traders priced a 72.4% probability of a quarter-point increase at the Fed's September meeting, up from 49.4% just one week earlier.5
The shift in rate expectations tracks the oil rally tightly. NYMEX WTI front-month touched $100 for the first time since mid-May on September 10 (2026-09-10), while ICE Brent surpassed $105 that session, driven in part by comments from President Donald Trump on Wednesday night (2026-09-09).3 By Thursday (2026-09-17), WTI had eased to $100.74 per barrel, but the market has so far given back very little of the summer's gain.
Federal Reserve Bank of Kansas City President Jeffrey Schmid put the central bank's bind explicitly at a conference in Iceland on May 29 (2026-05-29): with inflation stalled near 3% and above the Fed's 2% target "for a long time," the bank cannot simply "look through" surging oil prices, he said.1 Those remarks were made when crude was well below current levels.
Producer price data reinforced the message. The Bureau of Economic Analysis reported on September 10 (2026-09-10) that wholesale business inflation rose 0.4% from June to July, with the Producer Price Index up 5.4% on an annual basis.3 Both prints arrived that morning, when crude was approaching $107, Yahoo Finance reported.4
The underlying supply disruption traces to the US-Iran war that began in late February. Before the conflict, the Strait of Hormuz carried roughly 20% of global daily oil supply, NBC News reported.2 Washington has blockaded Iranian ports; Tehran has threatened the strait repeatedly. ICE Brent has risen approximately 20% since August as a result, NBC News reported.2
Diesel carries the clearest signal to consumers and freight operators. NYMEX ULSD heating oil front-month stood at $5.14 per gallon on Thursday (2026-09-17). The contract reached $5.78 per gallon on September 3 (2026-09-03), up 53% since the Iran conflict began, with refineries running near capacity at that point, NBC News reported.2 Positioning data on ULSD futures carries a bullish supply signal, diverging from crude's modest pullback since September 10 (2026-09-10).
Treasury markets captured the stress on September 10 (2026-09-10): the 10-year yield touched 4.93%, its highest since 2023, while the 30-year spiked to 3.35%, its highest since 2007, NBC News reported.3 The Dow Jones Industrial Average fell 380 points that session, with the S&P 500 down 0.7% and the Nasdaq losing 0.6%.4 Gold on Thursday (2026-09-17) traded at $4,309 per ounce, up 0.31% on the day.
The Fed faces two readings of the same data. Hiking into $104 oil risks compressing consumer spending; oilprice.com cited analysis warning that economic growth and consumption would suffer if prices remain at these levels or spike further.5 But standing pat while PPI runs at 5.4% annually invites the charge that the bank is again behind the curve. Schmid's Iceland remarks effectively ruled out the transitory framing before the latest oil surge began.
Persian Gulf shipping shows no credible path to de-escalation, traders said, according to NBC News.3 A further tightening of passage through the Strait of Hormuz would push crude back toward September's $105-$107 highs, making any November FOMC pause harder to justify. The NYMEX WTI front-month contract's position above $100 — and whether it holds there through October — is the number to watch.
