Iran declares Strait of Hormuz open, oil prices fall over 10%

Iran’s announcement that the Strait of Hormuz is “completely open” has sent oil prices down over 10%, and prediction markets on Strait traffic normalization are now repricing. The April 30 normalization market sits at 64.5% YES, down from 60% a day ago.

Market reaction

The drop in April 30 odds from 60% to 64.5% suggests traders are skeptical that Iran’s declaration alone will produce full normalization on that timeline. The May 31 market is stable at 87% YES, meaning traders still expect normalization but on a longer timeline. Combined 24-hour volume is $32,234 in USDC, and a move of just $354 can shift the price, which points to thin liquidity and sensitivity to small, possibly retail-driven bets. The largest recent move was a 4-point drop at 6:46 PM.

Why it matters

Iran’s announcement eases supply concerns and puts downward pressure on crude oil price forecasts for June. But sustained US naval blockades mean the gap between Iran declaring the Strait open and actual traffic normalization could be wide. The crude oil $90-by-June-30 market is directly affected by whether shipping volumes actually recover.

What to watch

The April 30 bet requires significant diplomatic progress within 14 days. Buying YES at 64.5¢ offers a potential 1.98x return if traffic normalizes by that date. Key triggers: statements from Iran’s Foreign Ministry, any US 5th Fleet announcements, or changes in Iranian naval activity that signal actual blockade removal rather than rhetorical positioning.
