Crude oil posted its sharpest one-day advance in weeks on Monday, jolting a stock market that had been drifting near record highs and pushing Treasury yields toward their highest levels since spring, as talks between the United States and Iran over reopening the Strait of Hormuz showed no sign of a breakthrough.
West Texas Intermediate crude settled at $82.13 a barrel, up 5.05%, while global benchmark Brent crude finished at $87.72, a gain of 4.99% — the best single-day performance for both benchmarks since July 29, according to Yahoo Finance. The rally lifted energy shares even as the broader market slipped: the S&P 500 and Dow Jones Industrial Average each eased roughly 0.1%, and the Nasdaq fell as much as 0.34% in Monday's session, according to TheStreet. The yield on the 10-year Treasury note climbed toward 4.70%, a level not seen since the spring, as traders weighed the inflationary bite of costlier crude against a Federal Reserve that remains divided on its next move.
A Waterway Still Effectively Closed
The pressure traces back to the Strait of Hormuz, the chokepoint through which roughly one-fifth of the world's seaborne oil normally passes. Shipping through the strait has been in disarray since a regional conflict escalated in late February, with daily tanker transits collapsing from around 130 before the war to as few as eight to fifteen in recent days, according to Al Jazeera's review of shipping data. The International Maritime Organization has documented at least 64 violent incidents involving commercial vessels since the conflict began, with 17 deaths.
Iran has continued to tie any reopening to conditions that go well beyond the strait itself. "As long as the U.S. naval blockade continues, the necessary conditions for the reopening of the Strait of Hormuz do not exist," an Iranian Foreign Ministry spokesman said, according to CNBC. Tehran is also demanding sanctions relief, the withdrawal of U.S. naval forces from the region, and compensation for war damage. President Trump said Monday that Iran "must pay compensation for all of the people that they have killed and gravely wounded," according to Reuters reporting carried by Yahoo Finance. Oman has been shuttling between the two sides to broker interim shipping arrangements, but negotiators have yet to announce an agreement as both governments' public positions harden.
Wall Street Weighs the Inflation Math
Energy shares were the rare bright spot in Monday's session — Chevron climbed 4.48% and the S&P 500's energy sector rose 4.46% — but the broader market's muted reaction masked real unease about what sustained $80-plus oil means for the inflation outlook. U.S. Strategic Petroleum Reserve stocks have fallen to their lowest level since January 1983, leaving Washington with less room to soften supply disruptions through releases.
The lack of concrete movement, together with lingering questions about the practical details of any agreement, is keeping a risk premium in the price.

"Each day that passes without a breakthrough is making traders a little more cautious," Waterer added. That caution is showing up across asset classes: gold has climbed toward $4,400 an ounce on safe-haven demand even as bond yields rise — an unusual pairing that traders say reflects genuine uncertainty about whether the Fed will need to hold rates higher for longer even as the labor market softens.
The next major test arrives Wednesday, when the Bureau of Labor Statistics releases its Consumer Price Index reading for July. Economists had penciled in a modest monthly increase before oil's latest leg higher; a hotter print, layered on top of a crude market still pricing in geopolitical risk, could harden the case for the Fed to stay on hold well into the fall — testing a market that had grown accustomed to a steadily improving rate outlook.
