Middle East tensions dominated markets again, with Brent crude holding near a six week high as the US and Iran traded strikes for a 12th straight night. CENTCOM confirmed the latest round of attacks on Iranian military targets was ordered directly by President Trump, aimed at further degrading Iran’s ability to threaten commercial shipping, following Tuesday’s use of a B-1 long-range bomber, the first such mission since this phase of the conflict began 12 days ago. Reports from Axios and the Wall Street Journal added that Washington is surging special forces, jets and medics into the region alongside an extra $73bln in war funding, underscoring how quickly the conflict is escalating on the ground even as diplomatic channels through Qatar remain open.
The other major thread overnight was the widening threat to shipping. Iran’s Revolutionary Guards declared the Strait of Hormuz fully closed, warning no tanker will transit without their coordination and threatening to halt oil flows entirely if Iranian infrastructure comes under attack, a claim that followed reports of one tanker catching fire and two others turning back near the strait’s mined southern route. Simultaneously, the Houthis extended their own campaign into the Red Sea, claiming strikes on the Saudi tankers Layla and Encelia, though UKMTO said only one vessel had actually been hit. Around 9 to 10 ships have now abandoned plans to transit Bab el-Mandeb, and Kuwait reported intercepting drones over its own airspace, a sign the conflict’s shipping and airspace risks are spreading beyond the two original chokepoints. Gold’s pullback on the news marked a reversion to a more conventional risk reaction, even as the US dollar softened modestly against most peers.
That said, not every part of the market was in risk-off mode. Asian equities extended a sharp rally, with the Kospi up more than 3% and the Nikkei around 1% higher, as Google’s raised full year capex guidance of $195bln to $205bln, alongside strong Tesla earnings, reinforced the view that AI infrastructure spending remains firmly intact, a boon for chipmakers including SK Hynix and Samsung. Australia added its own data point to the mix, with June employment surging 76.3k against a 15k forecast. Taken together, markets are juggling a genuinely escalating Middle East conflict against a resilient AI driven equity rally, a combination likely to keep volatility elevated across oil, currencies and regional equities in the sessions ahead.
