Graham backs Iran blockade strategy with Trump, Hegseth amid nuclear deal collapse

Lindsey Graham’s endorsement of the Iran blockade strategy alongside Trump and Hegseth signals sustained conflict. The odds for a US-Iran nuclear deal by April 30 have dropped to 6.3%, down from 16% just 24 hours ago.

Market reaction

Traders have adjusted expectations across related markets. The nuclear deal market fell from 42% a week ago to its current level. The Hormuz blockade announcement market sits at 59.5% YES, showing skepticism around any near-term lifting of the blockade.

The market for Iran agreeing to end uranium enrichment by April 30 is now at 5.5%. With Graham backing the blockade, traders see less chance of Iran conceding to US demands under current conditions.

Why it matters

Graham’s support for the blockade as leverage against Iran’s oil exports keeps pressure high and diplomatic options narrow. The nuclear deal market collapsed from 42% to 6.3% in a single week, a move that tracks with the absence of any visible negotiation progress and the April 30 deadline now seven days away.

What to watch

Volume in the nuclear deal market hit $11,264 in USDC over the last 24 hours, with a 3-point spike at 10:09 AM. The order book is thin: just $1,307 would move the price 5 points, meaning even small trades can swing odds significantly. The Hormuz blockade market had $32,536 in daily USDC volume and still saw a 3-point drop in its largest move.

Buying YES in the nuclear deal market at 6¢ per share offers a potential 16.67x return, but that requires a diplomatic turnaround within seven days. Watch for direct statements from Trump or new sanctions, and Hegseth’s upcoming Pentagon briefings for operational updates.
