Global crude oil prices fell this week after U.S. President Donald Trump announced a peace agreement with Iran [1].

The deal is critical because it aims to reopen the Strait of Hormuz, a vital artery for global energy shipments that had been restricted by a naval blockade.

Prices began to slide on Sunday, June 14 [3]. Brent crude dropped below $85 per barrel [1], while West Texas Intermediate (WTI) fell as much as five percent to approach $80 per barrel [2]. These declines follow a period of significant volatility; oil prices had jumped about 14% since Iran effectively closed the Strait of Hormuz [4].

President Trump said an agreement with Iran had been reached and the United States would end its naval blockade on the country [5]. He also said online that the Strait of Hormuz will reopen after the deal is signed [6].

The shift in geopolitical tension has already impacted consumer costs. Gas prices have fallen below $4 per gallon [7].

Traders are monitoring the formal signing of the agreement to ensure the naval blockade is fully lifted. The region has remained a flashpoint for global markets, with the Strait of Hormuz serving as a primary transit point for oil leaving the Persian Gulf [4]. The sudden drop in prices reflects a market reaction to the reduced risk of prolonged supply disruptions.

“Brent crude dropped below $85 per barrel”

The reduction in oil prices signals a market pivot from a 'war premium' to a stability outlook. By removing the immediate threat of a blockade in the Strait of Hormuz, the agreement restores confidence in the global supply chain, which directly lowers the cost of crude and refined petroleum products for consumers.
