The Strait of Hormuz has reopened under restrictions, and the Polymarket contract on crude oil hitting $90 by the end of June is showing increased odds as tensions and transit controls persist.

Market reaction

The market is reacting to mixed signals. The strait has reopened, but Iranian traffic controls and a US naval blockade remain in place. The reopening points to a slight stabilization in oil supply, though risks persist if diplomatic efforts break down. The probability of crude oil reaching $90 by June continues to track these geopolitical conditions.

Why it matters

The shift from complete closure to controlled passage directly affects the oil supply chain. Iran’s imposition of quasi-tolls and the possibility of renewed blockades keep the market on edge. Any disruption to transit could push prices higher.

What to watch

Current trading volumes and market depth data are sparse, but the potential for price movement is significant. With the market’s face value at zero, traders are largely in wait-and-see mode. The strait’s reopening, combined with upcoming US-Iran talks in Pakistan, complicates the picture.

For traders, this is a contrarian setup. At current levels, a YES share for crude oil hitting $90 by the end of June could pay off if tensions escalate or supply disruptions worsen. But the market’s direction depends heavily on the outcome of diplomatic talks and whether current controls hold.

Key signals to monitor: the upcoming US-Iran negotiations in Pakistan, any changes in Iranian traffic control measures, statements from the International Maritime Organization, and US naval operations in the strait.
