Oil plunges over 10% as Iran officially reopens Strait of Hormuz during ceasefire

Markets unwind risk premium as supply fears fade after Hormuz reopening
Global oil prices experienced a dramatic collapse of more than 10 percent on Friday, offering a wave of relief to the world economy following Iran's announcement that it would reopen the critical Strait of Hormuz to commercial shipping. The move, directly linked to a new ceasefire in the Middle East, saw Brent crude, the international benchmark, plummet to below $90 a barrel, a stark reversal from the near-record highs driven by weeks of escalating geopolitical tension. This development immediately eased fears of a prolonged global energy crisis that had threatened to derail economic stability.
The announcement came from Iranian Foreign Minister Abbas Araghchi, who stated that commercial vessels would be permitted to pass through the vital waterway for the duration of a 10-day ceasefire between Israel and Lebanon. This truce, which began Thursday, follows weeks of intense fighting that resulted in significant casualties and displacement. Before the recent conflict and subsequent closure, the Strait of Hormuz was a conduit for approximately 20 percent of the world's daily oil supply, and its blockage had sent shockwaves through energy markets. The reopening, even if temporary, signals a potential de-escalation of a conflict that had put the global oil supply chain under severe pressure.
The news rippled through financial markets, triggering a significant rally on Wall Street and providing a much-needed boost to industries heavily reliant on fuel, such as airlines and shipping. The easing of oil prices lowers the projected costs for gasoline, transportation, and manufacturing, which could in turn help to curb rising inflation. However, the optimism is tempered with caution. Analysts note that while prices have fallen sharply, they have not returned to pre-crisis levels, indicating that a significant risk premium remains embedded in the market.
Despite the positive step, the situation remains extremely fragile and complex. While Iran's foreign ministry announced the opening, the powerful Islamic Revolutionary Guard Corps offered only qualified support, and Iran's parliamentary speaker later warned that the strait would not remain open if a U.S. blockade of Iranian ports continues. In response to Iran's announcement, U.S. President Donald Trump declared that the American naval blockade would stay in effect pending a more permanent peace deal, creating uncertainty for shipping companies seeking to navigate the crucial passage.
The international community, including the United Nations and leaders of several world powers, welcomed the reopening as a positive development but urged a more lasting and workable solution. The immediate future of global energy prices and regional stability now hinges on several critical factors. These include the success of the fragile Israel-Lebanon ceasefire, the outcome of potential high-stakes negotiations between the United States and Iran, and the practical realities of whether commercial shipping can safely resume under the conflicting declarations of the involved nations.
