Oil prices are swinging sharply this week after President Trump’s latest comments on Iran and renewed concerns about shipping through the Strait of Hormuz. A prediction market now gives crude a 7.4% chance of reaching a new all-time high by September 30.
Why the Strait of Hormuz Matters
The Strait of Hormuz is a narrow waterway between Iran and Oman. About 20% of the world’s oil passes through it. Any disruption there can send prices soaring. Trump’s recent remarks, which included threats of military action against Iran if it blocks the strait, have traders on edge. The market is pricing in a small but real risk of a supply shock.
Trump’s Iran Rhetoric
Trump has repeatedly warned Iran not to close the strait. His latest comments, made during a press conference, were seen as more aggressive than usual. “We will not allow Iran to hold the world’s oil supply hostage,” he said. The White House later clarified that the president was not announcing a new policy, but the damage was done: oil futures jumped 3% in the hours after his statement.
What the Prediction Market Says
Polymarket, a decentralized prediction platform, shows a 7.4% probability that crude oil will hit a new all-time high by the end of September. That’s up from 4.2% a week ago. The current all-time high for Brent crude is $147.50, set in July 2008. Traders are watching for any escalation in the region.
What’s Next
The market’s next test comes Thursday, when the U.S. Energy Information Administration releases its weekly inventory report. A big drawdown could add to the upward pressure. For now, the Strait of Hormuz remains open, but the 7.4% probability is a reminder that the oil market is one tweet or one tanker incident away from a spike.
