Global oil prices plunged Sunday as investors anticipated a potential agreement between the U.S. and Iran [1].

The shift in pricing reflects the high stakes of the Strait of Hormuz, a critical maritime chokepoint. If a deal opens the waterway, it could resolve a severe global supply shock that has kept energy costs elevated.

West Texas Intermediate (WTI) crude oil prices gapped lower to $92 a barrel [1]. This figure represents the lowest level for WTI since May 7 [1]. Brent crude also saw a significant decline, dropping roughly seven percent [2]. Overall, oil prices fell below $100 per barrel during the session [3].

Traders priced in the growing hope that a diplomatic resolution would stabilize the market [3]. The prospect of a deal led to a sharp retreat in prices as the risk of prolonged disruption in the Gulf region diminished.

However, the market remains volatile. While optimism drove prices down on May 24 [4], subsequent reports indicated a more complex situation. The U.S. said it had carried out strikes on missile launch sites in Iran [4]. These military actions cast a shadow over the promised peace deal and caused prices to rise again [4].

Investors have not yet fully celebrated the prospect of a deal due to these conflicting signals. The tension between diplomatic hopes and military action continues to create sharp swings in crude valuations [2].

The extreme volatility in oil prices highlights how sensitive global energy markets are to geopolitical stability in the Middle East. While the market reacts quickly to the possibility of increased supply through the Strait of Hormuz, the immediate reversal caused by U.S. military strikes suggests that traders view diplomatic progress as fragile. Until a formal agreement is ratified and enforced, oil prices will likely remain reactive to tactical military developments rather than long-term diplomatic trends.
