NEW YORK / LONDON — Global energy and financial markets faced a bruising end to the week as the war on Iran entered its 29th day. On Friday, March 27, 2026, oil prices surged by over 6%, while the major U.S. stock indices plummeted, reflecting deep investor skepticism over a potential ceasefire.
Energy: Brent Crude Surges Past $112
The international benchmark, Brent crude, jumped $4.56 (4.2%) to settle at $112.57 per barrel. Earlier in the session, prices spiked as high as $114 as traders reacted to new reports of Iranian strikes on Gulf infrastructure and the ongoing blockade of the Strait of Hormuz.
- WTI Performance: U.S. West Texas Intermediate (WTI) followed suit, rising 5.5% to settle at $99.64, briefly touching the $101 mark during intraday trading.
- The “Hormuz Premium”: Analysts estimate that the continued closure of the Strait has embedded a $15–$20 war premium into every barrel.
- The “Trump Factor”: While President Trump’s decision to delay infrastructure strikes until April 6 provided a brief respite earlier in the week, markets have developed what analysts call “immunity” to his optimistic rhetoric, focusing instead on the reality of a nearly month-long maritime blockade.
Wall Street: A Sea of Red
U.S. equities suffered their worst day in weeks, with the three major indices ending the week with significant losses as the “fear index” (VIX) spiked above 30.
| Index | Friday Change | Points | Status |
| Dow Jones | -1.73% | -793.47 | Near 8-month lows |
| S&P 500 | -1.67% | -108.31 | 5th consecutive weekly decline |
| Nasdaq | -2.15% | -459.72 | Correction Territory (10% off peak) |
- Tech Sector Rout: High-growth technology stocks led the decline. Nvidia and Microsoft fell 1% and 1.7% respectively, as investors fled “risk-on” assets in favor of gold and Treasury bonds.
- Inflation Fears: The spike in energy costs has reset expectations for interest rate cuts. The University of Michigan’s consumer sentiment index hit a yearly low of 53.3, with short-term inflation expectations jumping to 3.8%.
Global Impact: $11.5 Trillion Wiped Out
Since the conflict began on February 28, the total market capitalization of global stock exchanges has shrunk by an estimated $11.5 trillion.
- Europe: Germany’s DAX and France’s CAC 40 have seen even deeper monthly losses (over 10%) due to their higher dependency on Middle Eastern energy and Qatari LNG, which remains bottled up behind the Hormuz blockade.
- Asia: The Nikkei 225 and Kospi tumbled significantly on Friday, reflecting the vulnerability of Asian economies that rely on the Gulf for over 70% of their crude imports.
The April 6 “Energy Deadline”
Investment firms, including Goldman Sachs and JPMorgan, are now warning that if the April 6 deadline passes without a deal and the U.S. proceeds with the destruction of Iranian energy plants, oil could realistically test the $150–$200 per barrel range.
