Strait of Hormuz traffic may normalize by month end, Polymarket shows skew

Developments

A fertilizer price surge in Japan linked to tighter imports amid the Strait of Hormuz disruption was reported by The Japan Times this week. Traders on Polymarket are now pricing the contract that asks whether Strait of Hormuz traffic will return to normal by the end of June, with activity picking up as investors weigh supply-chain risk and potential policy responses.

The Japan Times reported that fertilizers such as urea, ammonium phosphate, and potassium chloride saw price pressures in Japan due to the ongoing disruption at the Strait of Hormuz, a key transit chokepoint for global energy and raw materials. The article notes that Japan imports the majority of its essential fertilizer inputs, making domestic farmers sensitive to shifts in international trade flows. Government measures meanwhile include stockpiling fertilizer and diversifying import sources to buffer against further supply squeezes. The piece situates fertilizer costs within broader food-security concerns as markets monitor how long the disruption might persist and what alternative suppliers may emerge.

Prediction Market Reaction

Polymarket data shows the binary contract is trading with No as the leading outcome at odds of 69.5%, while Yes sits at 30.5% as of now. The contract has seen a modest uptick in probability since yesterday, with volume approaching the high tens of millions in USD terms, indicating steady participation from traders positioning for a potential late-June settlement. The current skew favors the No outcome, reflecting bets that traffic in the Strait of Hormuz could normalize by the end of June, though liquidity remains distributed across both sides.
