Oil prices plummeted to levels not seen since the early days of the Iran war, while U.S. stocks soared to record highs Friday after Iran declared the Strait of Hormuz open for commercial tankers. The S&P 500 jumped 1.2%, marking its third consecutive week of gains, the longest streak since Halloween. The Dow Jones Industrial Average surged 868 points, and the Nasdaq composite climbed 1.5%.
The reopening of the Strait of Hormuz, a critical maritime chokepoint for global oil shipments, immediately reduced oil prices. Benchmark U.S. crude dropped 9.4% to $82.59 per barrel, while Brent crude fell 9.1% to $90.38. Despite the decline, prices remain above pre-war levels, reflecting lingering market caution.
President Donald Trump emphasized that the U.S. Navy’s blockade of Iranian ports remains 'in full force' until a deal is reached.
The easing of oil prices provided relief to industries with high fuel costs. United Airlines shares rose 7.1%, and Southwest Airlines climbed 5.1%. Cruise operators Royal Caribbean Group and Carnival gained 7.3% and 7%, respectively. Lower energy costs also boosted housing and auto-related companies, with Carvana climbing 7% on hopes of reduced loan rates.
A sustained drop in oil prices could alleviate inflationary pressures, potentially prompting the Federal Reserve to lower interest rates. The yield on the 10-year Treasury fell to 4.24%, which could lower mortgage and loan rates for American households and businesses. Companies like Builders FirstSource and PulteGroup saw significant gains, reflecting optimism about increased homebuying activity.
The strong start to earnings season also supported market gains, with financial institutions like State Street and Fifth Third Bancorp reporting better-than-expected results for the latest quarter.
