Oil Spikes as U.S. Revokes Iran Sales Waiver; Chip Selloff Weighs on Stocks

Hyperdash NewsMacro

U.S. stocks closed lower as an energy spike and a semiconductor selloff pressured equities. The S&P 500 slipped to 7,504, down -0.45%, after the Treasury revoked a license allowing sales of Iranian Crude, sending oil sharply higher and lifting volatility.

Scoreboard

Crude surged after the U.S. revoked the waiver permitting sale of Iranian oil, a move that followed reported tanker attacks. WTI jumped to 71.87, up +4.84%, and Brent climbed to 75.66, up +5.10%. The Nasdaq fell -1.16% to 25,819 as chip stocks sold off after Samsung earnings missed a high bar for artificial-intelligence demand. The VIX jumped +3.66% to 16.14, with wires also citing a report on changes to Russia's nuclear doctrine as a risk-off driver. Treasury yields rose, the ten-year at 4.545%, up +7bp, while the dollar firmed.

Key headlines

The takeaway

The session showed geopolitics and rates working against equities at once. The revoked Iran waiver lifted Crude and Treasury yields together, an unusual pairing that squeezed both energy-sensitive costs and rate-sensitive valuations, leaving the chip-heavy Nasdaq the day's clear underperformer.

Attention turns to whether the loss of Iranian barrels tightens supply further, and to the fallout from Samsung's results ahead of Nvidia's report. Traders are also watching the reported shift in Russia's nuclear doctrine and the path of Treasury yields for direction across risk assets.
