Iran warns of a closed Strait of Hormuz as market predictions indicate possible U.S. blockade updates by late May.

Is the Strait of Hormuz truly closed? An Iranian lawmaker has stated that the strait has reverted to its previously closed status, casting doubt on any immediate easing of tensions in the region. Current market indicators reflect a very high likelihood—set at 85%—that President Trump will announce the lifting of the U.S. blockade by May 31. Traders are currently predicting that a resolution may be reached sometime between late April and late May, as shown by an 11% likelihood for discussion progress by April 19, compared to the 85% for May 31.

What do these percentages say about market expectations? The substantial difference—ranging from 17.5% to 82%—suggests that while traders hold an optimistic view for late May, they are not expecting any major developments in the immediate days ahead.

Trade activity reflects moderate conviction regarding these projections. The market for UK warship passage by April 30 stands at an 8% YES, aligning with warnings concerning the strait's status. Over a recent 24-hour period, total USDC trading volume across these markets was approximately $33,928. This figure points to trader activity that, while active, does not indicate heavy investment or a definitive trend.

Ebrahim Azizi's remarks signal that Tehran remains firm in its stance, impacting prospects for diplomatic advancement before April 19. Should Trump announce the blockade's end before this date, the current market pricing for a YES share—trading at 11¢—would yield a return of 5.5 times the investment. This bet could only be rationalized if investors believe substantial diplomatic progress is likely to occur in the next few days.

Investors should remain vigilant for any official communications from Trump regarding the blockade. Additionally, updates from the Pentagon could significantly influence these markets, especially if they indicate any changes in enforcement strategies.
