Global oil markets saw a sharp decline on Friday after Iran announced that the Strait of Hormuz—one of the world’s most critical oil transit routes—had been fully reopened to commercial shipping following a ceasefire agreement in Lebanon.
Iranian Foreign Minister Seyed Abbas Araghchi stated that, “in line with the ceasefire in Lebanon, the passage for all commercial vessels through the Strait of Hormuz is declared completely open” for the duration of the truce. His remarks signaled a temporary easing of tensions in a region that had been on edge for weeks.
The announcement came nearly ten days after a fragile ceasefire arrangement involving the United States, Israel, and Iran was reached on April 8. A key obstacle to stability had been ongoing hostilities between Israel and Hezbollah, which were only brought to a halt on April 16.
Despite the reopening of the vital waterway, U.S. President Donald Trump made clear that Washington’s naval blockade targeting Iranian ports would remain in place. In a statement posted on Truth Social, Trump emphasized that while the strait was “completely open and ready for business,” restrictions on Iran would continue until bilateral negotiations were fully concluded.
The Strait of Hormuz, through which roughly 20% of the world’s oil and liquefied natural gas supplies pass daily, had seen traffic nearly collapse in recent weeks. This followed a wave of U.S.-Israeli strikes on Iran beginning February 28, and retaliatory Iranian actions targeting tankers and regional energy infrastructure.
The disruption had pushed global oil prices sharply higher. Brent crude oil surged to nearly $120 per barrel in March—levels not seen since the early stages of the Ukraine war in 2022. However, with the easing of tensions and the ceasefire taking hold, prices dropped by around 10% on April 17, falling below $90 per barrel.
The volatility in energy markets has had broader geopolitical and economic implications. Russia, a major energy exporter, benefited significantly from the earlier price surge, as increased demand and temporarily relaxed sanctions boosted its revenues. However, the United States allowed its sanctions waiver on Russian oil purchases to expire on April 11.
The International Monetary Fund recently revised Russia’s economic outlook, citing higher energy prices as a key factor. The IMF now expects Russia’s economy to grow by 1.1% in 2026, an upward revision of 0.3 percentage points.
Speaking on April 17, Alfred Kammer noted that rising oil and gas prices had been the primary driver behind the improved forecast. At the same time, he highlighted ongoing risks, including Ukrainian strikes targeting Russian energy infrastructure. Reports indicate that up to 40% of Russia’s oil export capacity was disrupted in March due to long-range drone attacks and tanker seizures.
As markets respond to the shifting geopolitical landscape, analysts warn that the situation remains fragile. While the reopening of the Strait of Hormuz has brought temporary relief, continued military tensions and strategic blockades could quickly reverse recent gains in global energy stability. (ILKHA)
