Oil prices saw a 10% decrease following the announcement from President Trump that the Strait of Hormuz is fully operational, confirming Iran's statement. Currently, there's an 87% probability in the market regarding an announcement for the lifting of the US blockade by May 31.

What does the market say about the likelihood of a blockade announcement?The trading market closed on April 17 with an 8% prediction of a positive announcement, indicating that traders were not expecting any news until now. By April 19, this figure rose to 27%, up from 13%, reflecting a cautious optimism among traders about a formal announcement.

Why is this development significant?The steady 87% probability for May 31 suggests a strong confidence in the resolution of this issue in the longer term. This trading market has a daily value of about $7,205, with actual USDC volume reported at $5,868. To influence price movements by 5 points requires an investment of approximately $3,730. The most significant price change recorded was a 2-point rise at 2:38 AM, moving from 79% to 81%.

What should investors monitor moving forward?As the April markets edge closer to resolution, the May 31 market emerges as the focal point of trading. A YES share priced at 82¢ will yield $1 if the blockade is lifted by the end date, equating to a return of 1.22 times the investment. Traders are anticipating continued compliance with ceasefire terms by both the US and Iran. The next major indicator for this situation will likely be a formal announcement from either the White House or Iranian state media related to the blockade’s termination.
