Trump Threatens Kharg Island Seizure, Oil Jumps Past $90

OPEC+ has roughly 5 million bpd of spare capacity, mostly in Saudi Arabia and the UAE. That cushion assumes the strait stays open. If Hormuz is blocked, spare capacity inside the Gulf is as trapped as Iranian barrels. The only swing barrels outside the strait are in the US, Brazil, and Guyana – about 2 million bpd of combined spare capacity.

The US Strategic Petroleum Reserve holds about 370 million barrels, down from 638 million in 2021. The IEA's coordinated release mechanism could add another 1.5 million bpd for six months, that assumes member states have the logistics to deliver.

Diplomatic track is still alive

CNN reported Thursday that US-Iran talks continued overnight despite the exchange of strikes, citing a diplomatic source. Trump's post came hours after those reports. The mixed signals – simultaneous threats and negotiations – are consistent with the administration's approach to Venezuela, where sanctions pressure and back-channel talks ran in parallel for months.

Traders are watching for any confirmation that the Kharg Island threat is operational planning rather than negotiating posture. A US naval buildup near the island would be the clearest signal. So far, Centcom has not announced any change in force posture beyond the existing carrier strike group in the Arabian Sea.

What would confirm the risk

The threat is real if the US moves amphibious or Marine assets into the northern Gulf. It is posture if the diplomatic track produces a framework deal within days. The Venezuela comparison cuts both ways: the US took control of Citgo's refineries and PDVSA's US assets, never seized Venezuelan oil infrastructure inside the country.

For crude, the next marker is the Strait of Hormuz. If Iran reopens it, the Kharg Island threat becomes a premium on Iranian barrels only. If it stays closed, the entire Gulf supply chain is disrupted, $100 crude becomes the floor, not the ceiling.
