Strait of Hormuz blockade threatens oil supply, market skeptical of price spike

A potential loss of a billion barrels of oil through the Strait of Hormuz has raised supply shock concerns, but the Polymarket contract for crude oil reaching an all-time high by April 30 sits at just 1.3% YES, down from 2% yesterday.

Market reaction

The crude oil all-time high market prices in heavy skepticism about crude surpassing $120/barrel by end of April, with odds at 1.3% YES. The blockade has cut off the Strait of Hormuz, which previously carried 20% of global oil supply. Traders appear unconvinced that prices will spike to record levels, even after a ceasefire announced on April 8 failed to restore flows.

The market is thin. Daily volume is $2,513 in actual USDC against a $100,828 face value. It takes only $695 to move the price 5 points, meaning a single large order could swing it significantly. The biggest move was a 1-point spike at 5:31 AM, suggesting cautious activity rather than conviction.

Why it matters

If the blockade persists and infrastructure remains unrepaired, oil prices could challenge current market expectations. At 1.3¢, a YES share pays $1 if crude hits a new high, a 76.9x return. Anyone who believes supply constraints will last long enough to push crude past its all-time high can take that position cheaply.

What to watch

Diplomatic breakthroughs or OPEC+ production decisions are the main catalysts. Resumed flow through the Strait or increased output from other producers would likely cap prices. US-Iran relations and military developments in the region are the key variables over the coming days.
