Dow Slips 84 Points as 30-Year Yield Hits 5.446% Despite Hormuz Deal Hopes

Q: Could a sudden breakthrough in U.S.-Iran negotiations instantly reverse the massive spikes in global oil and bond yields?

No. A credible U.S.-Iran breakthrough could quickly knock down part of the geopolitical risk premium in oil and trim some inflation fears in bonds, but it would not instantly erase the full spike in either market. Oil would likely react fastest. Reports of possible talks already briefly capped losses in stocks and pulled crude off intraday highs, showing how sensitive prices are to any sign of progress. If a deal clearly reopened the Strait of Hormuz and reduced attacks on shipping, Brent and WTI could fall sharply in the short term because traders would reprice disruption risk, war-risk insurance, and freight costs. But prices would probably not snap all the way back at once. Physical flows, tanker routing, port operations, and insurance markets need time to normalize, and Red Sea and Saudi export risks could still keep a residual premium in place. Bond yields are even less likely to reverse instantly. Higher oil prices have fed inflation concerns, but the Treasury selloff is also being driven by strong U.S. PMI data, rising expectations of another Federal Reserve hike, and a broader increase in term premium for holding long-dated debt. That means even if oil dropped on a diplomatic breakthrough, yields would still reflect resilient growth, sticky input costs, heavy debt supply, and hawkish Fed expectations. So the most realistic market response would be a fast partial reversal in oil and a more modest, uneven decline in Treasury yields, not a full immediate unwind.

U.S. stocks wavered Thursday, with the S&P 500 and Nasdaq flat while the Dow fell 84 points after early losses eased on a Reuters report that U.S. and Iranian negotiators may strike a phased deal to reopen the Strait of Hormuz.
Treasury yields kept pressure on equities: the 30-year bond yield touched 5.446%, its highest since 2004, and the 10-year climbed to 5.15%, near a 2007 high.
Oil also limited any rebound, with Brent up 2% to about $105 a barrel and WTI up 2% to around $94, reinforcing worries that energy costs could feed inflation.
Rate expectations hardened alongside those moves, with Fed funds futures implying a 66% chance of another Fed hike in October, up from about 55% a week earlier.
The backdrop is a resilient U.S. economy—strong PMI readings suggested business activity is still booming—leaving investors focused less on recession risk than on how long rates above 5% can weigh on housing, borrowing and valuations.
