Oil Rockets to $105 as Iran Vows to Escalate, Dow Falls for a 4th Day

Brent crude spiked to $105 a barrel Thursday morning as escalating tensions in the Middle East heightened concerns over global oil supply, while WTI crude traded above $100. The move extended a run-up that's now weighing on stocks for a fourth straight session and pushing Treasury yields to levels not seen in nearly three years.

Iran signaled it has no intention of standing down in the face of an American naval blockade and warned it will escalate its strikes if the U.S. continues attacking Iranian territory — language that markets read as a sign the conflict is more likely to widen than de-escalate in the near term. President Donald Trump added to the grim outlook for energy prices, saying the war would only end after the November midterm elections and that meaningful gasoline price relief would not arrive before then.

Oil's relentless climb

Brent's move to $105 and WTI's push above $100 mark a meaningful escalation from earlier in the week, when crude was trading in the mid-$90s on the same underlying conflict. Iran's explicit warning that it will escalate strikes if U.S. attacks continue removes any near-term hope of a de-escalation-driven pullback in prices, and Trump's comment that the war won't end before the midterms effectively extends the timeline markets have to price around.

The real-economy impact is already visible at the pump. According to a note from veteran economist Gary Shilling, the national average for regular unleaded gasoline has spent 122 days — roughly half of 2026 so far — at or above $4 per gallon. With Trump now explicitly ruling out relief before November, that streak looks likely to extend rather than break.

Dow falls for a fourth straight session

The Dow is on track for its fourth consecutive down day, with the S&P 500 and Nasdaq also lower as oil prices and Treasury yields climb in tandem. It's the same rate- and energy-driven pressure that's defined this week's tape: a market that isn't reacting to a single new shock so much as absorbing a steadily worsening combination of higher-for-longer oil and higher-for-longer rates.

Treasury yields hit a 34-month high

The 10-year Treasury yield climbed to 4.914% intraday, its highest level since October 31, 2023, taking its cue from both the relentless run-up in oil prices and this morning's producer price index, which showed wholesale inflation rising 5.4% year-over-year in August. Yields move inversely to bond prices, so the climb reflects sustained selling in the Treasury market.

The parallel move in oil and yields today is hard to miss. While inflation hasn't been the primary driver of this year's rise in yields, it's becoming a bigger factor lately — and the mechanism is straightforward: higher energy prices feed expectations for higher inflation, and when investors expect prices across the economy to rise, they demand a bigger payout from bonds to compensate. This morning's hot PPI print did nothing to interrupt that selling pressure; if anything, it reinforced it.

What it means

Today's moves tie together three threads that have each been building independently this week: an Iran conflict that shows no sign of a near-term resolution, a Treasury market that's demanding more yield as inflation risk creeps back into the conversation, and a stock market that's now absorbed four straight days of that pressure. With gasoline relief explicitly pushed past the midterms and Iran signaling further escalation rather than restraint, the setup argues for continued volatility in both energy and rates markets rather than a quick reversal.
