Midday Mashup
Published
The twin forces pressuring markets since Thursday, an escalating Strait of Hormuz conflict and an unwinding AI infrastructure credit trade, have both intensified through midday rather than stabilizing. Oil has pushed decisively higher, with US crude rising more than $3 to a session high above $101 a barrel and Brent near $107, as Iran's army chief vowed the strait will stay closed until Iranian demands are met and a Russian refinery halted a primary unit after an October 15 drone strike. The Department of Energy is now soliciting an exchange of up to 17 million barrels from the Strategic Petroleum Reserve as supply strain builds.
That has fed a sharp divergence on the tape. Energy producers are among the biggest gainers, with Matador Resources up 5.8%, SM Energy and Permian Resources both up 3.7%, as higher crude flows directly into upstream economics. Meanwhile the AI financing unwind has deepened into a broader risk-off move: the Nasdaq 100 has extended its decline to 2% and the Cboe Volatility Index has jumped 26.0% to a four-month high. CoreWeave is down 11.9% after short sellers reportedly booked roughly $806 million in paper profit on Wednesday's slide, and Nebius Group and Super Micro Computer are off 10.2% and 9.7% respectively. Moderna is down 10.1%, and the iShares MSCI Indonesia ETF has extended its post-MSCI-review slide to 14.2%.
Karman Holdings is a rare bright spot up 5.1% even as most growth and high-beta names are sold.
Politics added to the volatility narrative: White House press secretary Katie Zacharia is out after just five days on the job, with Trump saying she will stay on in some other role, while he separately reiterated confidence in a future nuclear arms deal with Russia and China and called the US economy "never stronger." Overseas, Germany's Merz said it is understandable if Ukraine strikes Russian energy and communications infrastructure, and von der Leyen flagged a 70 billion euro Ukraine funding gap for 2027, both signs that the European dimension of the conflict is widening alongside the oil shock.
Taken together, the session shows a market pricing a genuine energy supply shock on top of, not instead of, the AI credit stress, with volatility and crude moving up in tandem while growth and tech names absorb the damage.
