US stock futures fall as Middle East tensions push oil prices and bond yields higher

US stock futures are down, led by a 1% drop in the Nasdaq-100, due to escalating tensions in the Middle East. President Trump's threats against Oman and Iran have driven oil prices up to their highest in two weeks, with Brent crude at $91 a barrel. Rising oil prices stoke inflation fears, causing US Treasury yields to climb to multi-year highs amid heavy government borrowing and strong demand for AI investments. Despite the turmoil, Home Depot shares rose 1% pre-market, while Toll Brothers and Klarna await earnings reports.
