Iran’s declaration that the Strait of Hormuz is fully open sent oil prices tumbling and lifted global equity markets on Friday, with U.S. Crude falling more than 10% and the S&P 500 rising 1.4% as traders welcomed a de-escalation in Middle East tensions.
The Strait, a vital chokepoint for about one-fifth of global oil trade, had been under threat of disruption for weeks as regional hostilities flared. When Iran confirmed commercial traffic could resume unimpeded, benchmark Brent crude dropped 10.6% to $88.85 a barrel while West Texas Intermediate slid 12% to $82.88, erasing recent premiums tied to supply anxiety.
Airlines, which treat jet fuel as their largest variable cost, were among the clearest beneficiaries. In Europe, easyJet gained 6.1%, Wizz Air rose 7.6%, and International Consolidated Airlines Group climbed 6.2%. Lufthansa, which had warned of grounding planes due to fuel costs the prior day, erased its morning losses to close 5.6% higher.
In the U.S., American Airlines shares jumped in afternoon trading, though the move was measured against the stock’s volatility. The carrier has seen 24 single-day swings exceeding 5% over the past year, meaning today’s gain reflected meaningful but not transformative news. At $12.77, the stock remains 21.5% below its 52-week high of $16.26 set in December 2025 and down 17.5% year-to-date.
Broader markets responded to the shift in risk sentiment. The pan-European Stoxx 600 rose 1.6%, led by a 4.7% gain in travel and leisure stocks. On Wall Street, the Dow Jones Industrial Average added 2.2% as the dollar weakened and bond yields steadied, reflecting reduced demand for safe-haven assets.
Energy stocks stood apart as the notable decliners. BP fell 7.4% in London, Shell dropped 5.6%, and Norway’s Vår Energi lost 6.2%, underscoring how swiftly commodity markets react to geopolitical shifts that ease supply fears.
Meanwhile, technology stocks continued their independent rally. The Nasdaq Composite rose 1.52% to close at a record 24,468.48, buoyed by strong earnings from Taiwan Semiconductor Manufacturing Company and renewed investor confidence in artificial intelligence-related capital expenditures. Among the week’s top performers, Strategy gained 28.04% as Bitcoin broke resistance, AppLovin rose 26.91%, and DoorDash climbed 18.98%.

The market’s reaction also revealed a divergence in how investors interpret geopolitical news. While the Strait’s reopening eased immediate fears of oil shocks, it did not alter the underlying calculus for airlines facing structural challenges like labor costs, fleet aging, and competitive pressures — factors that left American Airlines well below its peak despite the fuel-price tailwind.
That disconnect was echoed in Europe, where Lufthansa’s rebound came after it had just announced capacity cuts due to fuel costs, illustrating how quickly market sentiment can pivot on single data points even as operational realities lag.
By late afternoon, the rally had extended beyond traditional sectors. Bank stocks gained on resilient consumer balance sheets, while software and semiconductor firms extended their gains, suggesting the market was pricing in a broader reduction in systemic risk rather than sector-specific relief.

The move also highlighted how quickly narratives can shift. Just days earlier, markets had been braced for a potential blockade of the Strait as U.S. Officials signaled heightened vigilance; the sudden reversal underscored the fragility of risk assessments built on diplomatic flashpoints rather than structural supply fundamentals.
Why did airline stocks rise if fuel is only part of their cost structure?
Airlines gained given that jet fuel typically represents 20-30% of operating expenses, making it a significant lever for profitability when prices move sharply, even if other costs like labor and maintenance remain unchanged.

Did the drop in oil prices hurt energy companies across the board?
Yes, integrated oil majors and exploration firms declined as lower crude prices directly compress future revenue expectations, with BP, Shell, and Norwegian producer Vår Energi all falling between 5.6% and 7.4% on the day.
Was the market’s reaction to the Strait’s reopening disproportionate to the news?
For some stocks, yes — particularly volatile names like American Airlines, where today’s move was meaningful but not enough to alter the long-term view of a share still down 17.5% year-to-date and trading well below its 52-week high.
