US stocks traded lower through Tuesday morning as Crude prices jumped after President Trump rejected an Iranian proposal to reopen the Strait of Hormuz, and Treasury yields climbed amid a global selloff in government bonds. The S&P 500 fell -0.83% to 7,679.

The morning's main driver was energy. WTI jumped +3.39% to 95.54 and Brent rose +3.51% to 107.98 after the White House rebuffed Iran's offer to reopen the Strait of Hormuz. Treasury yields moved higher as global government bonds came under pressure, with the US 10-year rising +8bp to 5.263%. Reports that President Putin updated Russia's nuclear doctrine were cited as a driver of the move in futures and yields. The VIX jumped +9.62% to 16.30. The dollar edged up, the DXY gaining +0.24% to 101.2150. The Nasdaq fell -1.00% to 26,799.

The takeaway

Nvidia added a one-hundred-fifty-billion-dollar boost to its share buyback plan, and a reported US-China tariff cut on sixty billion dollars of goods offered a counterweight to the morning's risk-off tone. Neither was enough to offset the pull of higher oil and rising yields across the tape.

Attention turns to whether oil holds its morning gains as the Hormuz standoff develops and to any further reports on Russia's nuclear doctrine. Traders will watch the afternoon path of Treasury yields after the global bond selloff, the dollar at 101.2150, and whether the Nvidia buyback and US-China tariff news lend support into the close.
