The Strait of Hormuz has reopened, and the Polymarket S&P 500 up or down on April 14 contract sits at
Market reaction
The reopening eased fears of a prolonged oil chokehold, and equity markets rallied on the news. The S&P 500 April 14 market at 100% YES reflects trader confidence that reduced geopolitical risk and lower energy costs will carry the index higher. For crude oil, the reopening makes a $90 price by June look less likely. The crude oil price by end of June market should see decreased odds as traders discount the probability of supply disruptions. The temporary ceasefire is tied to broader peace negotiations, but its conditional nature keeps the situation fragile.
Why it matters
The equity relief rally and the softening oil outlook are moving in opposite directions. The S&P 500 market benefits from the removal of immediate supply-disruption risk, but the oil market remains cautious because the ceasefire expires April 22. Actual vessel traffic through the Strait has not yet increased, meaning operational constraints are still in place even with the political agreement.
What to watch
The next signals are updates on peace talks and any extension of the ceasefire past April 22. A breakdown in negotiations or renewed tensions could reverse both moves quickly. Any announcement of a final peace deal would be the strongest catalyst for stabilizing both markets.
