Oil Surges and Markets Slide as U.S.-Iran Tensions Flare

Fresh tensions between Washington and Tehran pushed oil higher and triggered selling in stocks and bonds, with Brent crude rising over 2% toward $107 a barrel. The two-year Treasury yield climbed about 5 basis points to 4.90%, the 10-year rose about 4 basis points, and the dollar strengthened against most major currencies. Bitcoin fell below $83,000 in 24 hours, while Asian equities and Nasdaq 100 futures also declined.
Renewed friction between Washington and Tehran lifted Brent by more than 2% to nearly $107 after Iran’s conditions over the Hormuz Strait were rejected. Its proposal tied reopening the strait and nuclear talks to looser limits on Iranian oil.
Shorter-dated Treasuries led the bond selloff, with the two-year yield up about 5 basis points to 4.90% and the 10-year up 4 basis points. A global bond gauge averaged above 4% for the first time since 2007. The dollar rose, metals fell, Asia-Pacific shares dropped 0.6%, Nasdaq 100 futures declined, and Bitcoin traded below $83,000.
Higher energy costs may feed through to fuel, transport, food and household budgets, while tighter financial conditions could weigh on borrowers and businesses. Investors with pensions or savings may see short-term swings as stocks and bonds reprice. Consumers in import-dependent economies could be especially exposed if oil stays elevated. Geopolitical uncertainty may also affect currency-sensitive sectors and crypto holders.
