Iran tightens grip on Strait of Hormuz, impacting US oil sanction relief odds

Iran has tightened its grip on the Strait of Hormuz in retaliation against the US. Trump’s Iranian oil sanction relief by April now sits at 36.5% YES, down from 62% yesterday.

Market reaction

The odds for Trump agreeing to Iranian oil sanction relief dropped sharply, consistent with escalation rather than progress toward a deal. The market for a US-Iran diplomatic meeting by June 30 remains at 3.7% YES, showing little expectation of near-term diplomatic engagement.

Why it matters

The term structure in the permanent peace deal market tells the story. The probability of a deal by April 22 is at 16.5% YES, down from 40% yesterday. That collapse shows how directly Iran’s Hormuz actions hit traders’ expectations for a quick resolution. Further out, June 30 odds sit at 67.5% YES, suggesting traders still see a deal as more likely than not over a longer horizon.

The US-Iran peace deal market has $1.6M in actual USDC traded. It takes $14,798 to move the odds by 5 points, which means the book has enough depth to absorb one-off trades without wild swings.

What to watch

The Strait of Hormuz is the transit point for roughly a fifth of global oil supply, so Iran’s move here has real leverage. A YES share for Trump agreeing to sanctions relief by April is priced at 48¢, offering a potential 2.08x return. That bet requires a rapid diplomatic breakthrough, which the current trajectory makes hard to justify.

Watch for official statements from Trump or the White House on military actions or sanctions. The next Pentagon briefing or any confirmation of diplomatic talks could move these markets fast.
