The cost of Brent crude oil for August delivery took a significant hit on Monday, dropping 4.67% to $83.27 per barrel. This decline followed the announcement of a peace agreement between the United States and Iran, which is expected to lead to the reopening of the strategic Strait of Hormuz.
At 7:00 a.m. on Monday, Brent crude, the benchmark oil price for Europe, reached its lowest point since early March 2026. This comes just days after the onset of armed conflict in the Middle East, as reported by EFE.
The drop occurred after President Donald Trump revealed on Sunday via his social media platform, Truth Social, that an agreement had been reached with Tehran to reopen the Strait of Hormuz. The closure of this vital passageway had caused significant disruptions to the global energy supply.
"The agreement with the Islamic Republic of Iran is now finalized. Congratulations to everyone! I hereby authorize the toll-free opening of the Strait of Hormuz and simultaneously approve the immediate lifting of the U.S. naval blockade. Ships of the world, start your engines! Let the oil flow!" Trump posted, offering no further details about the deal.
In exchange for reopening the strait, Washington will lift the naval blockade that had restricted the movement of ships in and out of Iranian ports.
The conflict, which now seems to be nearing resolution, began on February 28, 2026, with "Operation Epic Fury," a joint military offensive by the United States and Israel targeting Iranian nuclear and military facilities.
On March 4, Iran responded by closing the Strait of Hormuz, a route that accounts for approximately 20% of the world's oil and between 20% and 25% of global liquefied natural gas. This action caused Brent crude prices to soar above $100 per barrel.
On April 13, the U.S. imposed a naval blockade on Iranian ports, which pushed crude prices to $102, and by May, Brent prices had surpassed $120 per barrel. Projections from Goldman Sachs and Citi had suggested prices could reach $140-150 if the blockade continued.
Pakistan, acting as a mediator between Washington and Tehran, was the first to publicly announce the agreement, with Prime Minister Shehbaz Sharif confirming an immediate and permanent cessation of military operations.
The pact was reached after weeks of draft exchanges and contradictory statements. As recently as last Friday, Iran was dampening Pakistan's optimism about an imminent signing.
The announcement coincided with President Trump's 80th birthday on Sunday, a date he had pushed to align with the agreement's announcement.
The agreement reportedly includes the unfreezing of approximately $12 billion in Iranian assets, though specific details, particularly regarding Iran's nuclear program, remain undisclosed.
Both parties are scheduled to sign a memorandum of understanding, referred to as the "Islamabad Agreement," in Switzerland on Friday, June 19, to formally conclude all hostilities, according to Iran's Deputy Foreign Minister Ali Gharaibabadi.
