Secretary of State Marco Rubio warned that Iran's push to control and collect tolls in the Strait of Hormuz could endanger global shipping and the world economy. He made the warning at an ASEAN gathering in Manila, as Polymarket odds show a 24.6% probability that there will be no US-Iran talks by September 30.
Warning at ASEAN Gathering
Speaking at the Association of Southeast Asian Nations meeting in Manila, Rubio said Iran's reported efforts to impose tolls on vessels passing through the Strait of Hormuz threaten a vital chokepoint for global energy and trade. The strait handles about a fifth of the world's oil supply. Rubio did not specify what actions the US might take, but his remarks signal growing concern in Washington over Tehran's ambitions in the region.
Market Odds on Talks
Polymarket, a decentralized prediction platform, currently prices a 24.6% chance that no US-Iran talks will occur by September 30. That leaves a 75.4% probability that some form of dialogue will take place before the deadline. The odds reflect uncertainty among traders about whether the two countries can find common ground amid escalating tensions over Iran's nuclear program and its regional activities.
The Strait of Hormuz is a narrow waterway connecting the Persian Gulf to the Gulf of Oman. Any disruption there could send oil prices soaring and choke supply chains that rely on tanker traffic. Iran has previously threatened to block the strait in response to sanctions or military pressure. Rubio's warning suggests the US views the toll plan as a new form of economic coercion that could destabilize markets.
The warning comes as the Biden administration continues to explore diplomatic channels with Iran, though no formal talks have been announced. The 24.6% probability on Polymarket indicates that a significant minority of bettors see a path to no negotiations by the end of September. Whether that reflects optimism about a deal or pessimism about the chances of talks remains unclear.
For now, the situation remains fluid. The next concrete milestone is September 30, when the Polymarket contract expires and the world will know whether US-Iran talks happened or not.
