Oil prices dropped to a six-week low on Thursday after the U.S. and Iran tentatively agreed to extend a ceasefire by 60 days [1], [2].

The agreement aims to stabilize global energy markets by reducing geopolitical tension in the Strait of Hormuz. Because this waterway is a primary chokepoint for crude oil, any perceived increase in security encourages traders to anticipate improved supply flows and lower costs.

President Donald Trump announced the extension on May 28, 2026 [1]. The move sparked immediate market reactions, with some investors positioning themselves for a sustained decline in crude prices. Traders placed bets worth $430 million [2] on a decrease in prices 15 minutes before the announcement was made public, a Yahoo Finance report said.

Market analysts said the renewal of the truce eases the risk of conflict that previously drove prices higher. The optimism that the Strait of Hormuz may soon reopen fully has contributed to the downward pressure on oil [1].

However, the market response has not been entirely uniform. Bloomberg reported the drop to a six-week low [1], while other reports indicated that some prices rose as doubts persisted regarding whether the U.S. and Iran would hold further fresh talks [1].

Despite these contradictions, the prevailing sentiment among many high-volume traders remains bearish. The scale of the $430 million bet indicates a significant conviction that the ceasefire will prevent the supply shocks typically associated with regional volatility [2].

The volatility in oil pricing reflects a tug-of-war between short-term diplomatic optimism and long-term skepticism. While a 60-day extension provides a temporary window of stability, the market's sensitivity to the Strait of Hormuz means that any sign of the truce failing could trigger a rapid price reversal. The massive financial bets by traders suggest that the market is currently pricing in a diplomatic resolution over a military escalation.
