Uncertainty around the Strait of Hormuz is rising as the market prices in a greater chance of US airstrikes on Iran and the possibility of longer shipping disruptions through one of the world’s most important oil routes.
Walter Bloomberg reported on July 21 that traders on prediction market Kalshi are now assigning a 31% chance that maritime traffic through the strait returns to normal before December 2026. The market is also pricing in the risk that disruption could stretch into 2027, a sign that traders see the threat as more than a brief flare-up.
President Donald Trump said the US would strike the “Pickaxe Mountain” area near Iran’s Natanz nuclear facility “soon.” The site is known as a deeply buried fortress tied to Iran’s nuclear program, and the comment sharpened concern that any military move could widen the conflict. That has put the narrow waterway back in focus for oil traders.
The Strait of Hormuz carries a large share of the world’s seaborne crude and fuel shipments, so even the threat of interference can ripple through energy prices, freight rates and broader risk assets. Crypto usually trades as a risk-sensitive market, and tensions in the Middle East often feed demand for defensive positioning while also lifting attention on inflation-linked headlines and oil.
For now, the key watch item is whether Washington follows through on the threatened strike and whether shipping traffic through the strait is affected in the days after any action. Traders are also watching Kalshi’s odds for any shift toward a faster normalization date, which would suggest the market is backing away from its worst-case timeline.
US strike threat on Iran raises risk of prolonged oil shipping disruption
Traders now see only a 31% chance that Strait of Hormuz shipping returns to normal before December 2026 after President Donald Trump threatened a US strike near Iran’s Natanz nuclear facility. Because the strait carries much of the world’s seaborne crude and fuel, a prolonged disruption could raise oil prices and freight costs while increasing pressure on risk-sensitive markets, including crypto.
