Oil prices surged Wednesday after the United States carried out its 11th consecutive night of airstrikes on Iranian military targets, while Secretary of State Marco Rubio publicly declared that Tehran was failing to honor previously agreed terms and was "not serious about talks." Brent crude futures climbed 3.5% to $94.22 a barrel in early trading, their highest level in more than a month, while the front-month US West Texas Intermediate contract advanced 3.8% to $87.56.
Speaking at the ASEAN Foreign Ministers' meeting in the Philippines, Rubio said Washington remained committed to diplomacy but accused Iran of not following through on Strait of Hormuz commitments that had been part of a preliminary framework discussed at the Swiss Burgenstock talks in late June. Iran also intensified its own retaliatory operations overnight, with Kuwait reporting drone attacks on its territory by Iranian forces, and the US confirming strikes on US facilities in Bahrain and Jordan as well.
The breakdown in diplomatic progress sent shockwaves through financial markets. Deutsche Bank strategist Jim Reid noted in a morning client note that Brent closing above $90 a barrel for the first time in over a month had brought inflation fears roaring back. Money markets responded sharply: the probability of a Federal Reserve rate hike at this month's July FOMC meeting rose to 24.1% by Wednesday morning, up from roughly 10% immediately following last week's softer-than-expected US CPI print and back toward the 45% level seen before that data surprised to the downside.
The repricing of rate expectations rippled across US equity futures. Nasdaq-100 contracts fell 0.9%, while S&P 500 futures dropped 0.3% and Dow Jones Industrial Average futures declined 0.1%. The technology sector, which had led a sharp two-day rebound through Tuesday, was the hardest hit in pre-market trading as investors unwound risk positions ahead of a high-stakes evening that includes Alphabet and Tesla earnings reports after the close.
The energy sector was the standout gainer. Shares of major oil producers rose in pre-market, while defense and aerospace stocks also moved higher as the extended conflict reinforced expectations of sustained elevated government spending on military hardware and logistics. Airline stocks moved in the opposite direction, as the renewed spike in jet fuel costs threatened a round of margin guidance downgrades from carriers that had begun to benefit from a brief period of easing crude prices in late June.
The conflict has now run for more than four months, with each cycle of diplomatic progress followed by a resumption of hostilities that resets oil price risk premia. Analysts at Goldman Sachs noted that Brent remaining above $90 through summer would likely delay the Federal Reserve's first rate cut well into 2027, compressing equity multiples across the board and creating particular headwinds for rate-sensitive sectors including real estate, utilities, and long-duration growth names.
Market participants are also watching the Bank of Japan, with the yen hovering near 163.03 to the dollar — close to a 40-year low — as persistent dollar strength tied to higher-for-longer US rate expectations continues to weigh on the Japanese currency. Investor focus for the remainder of Wednesday centers on Alphabet and Tesla results after the close, which are expected to provide the clearest read yet on whether AI-driven corporate earnings can offset the macro headwinds accumulating from the energy price shock and rising rate expectations.
