Global financial markets began in March 2026 under intense geopolitical stress. This followed a major escalation in Middle East history. The United States and Israel carried out their biggest attack on Iranian targets. This happened over the weekend. They killed Iran’s longtime Supreme Leader, Ayatollah Ali Khamenei. This act led to a rising conflict. Tehran responded with air strikes throughout the Middle East.
The fallout was swift and wide. Stocks fell, and oil prices jumped when war broke out between the US and Iran. This rattled global markets. Gold and the dollar jumped as people sought safe options. Meanwhile, S&P 500 futures dropped 1.5% as stocks fell worldwide. Nasdaq 100 contracts fell by 1.9%. Brent crude was close to $80 a barrel. This drop follows the conflict that has shut the Strait of Hormuz. This strait is crucial, carrying about one-fifth of the world’s oil and a lot of gas.
Equity Markets Take a Hit Worldwide
Global stock markets began in March 2026 with major geopolitical tensions. Military strikes by the United States, Israel, and Iran caused the Strait of Hormuz to close. This caused a sharp rise in commodity prices while equity indices fell.
In Asia, Japan’s Nikkei 225 was the first to feel the impact. It dropped nearly 2% at the start, but closed at 57,833.79, down 1.73%. The Hong Kong Hang Seng Index fell 1.58% to finish at 26,209.91. This decline was mainly due to technology stocks dropping. Consumer discretionary stocks also fell.
In Europe, the UK’s FTSE index opened 0.6% lower. Germany’s DAX was down 1.5%, France’s CAC 40 fell 1.4%, and Italy’s FTSE MIB dropped 1.2%.
On Wall Street, the Dow Jones Industrial Average futures fell 627 points, or 1.27%. The S&P 500 futures lost 1.32%, while the Nasdaq 100 futures declined 1.71%.
Oil, Gold & Safe Havens Surge
Energy and defence stocks rose, while airlines fell across Asia.
Global equities began the week cautiously. Oil saw the biggest shift, with Brent crude rising by up to 13% before settling.
The swift conflict unsettled investors. This led to more safe-haven trades, including Treasuries, gold, and the Swiss franc. The US dollar strengthened, and the Swiss franc also gained against major currencies.
COMEX Gold increased by 2.53% to $5,362.70 per ounce. Investors turned to this safe-haven asset due to worries about a broader regional war. Gold’s rise fits a larger trend; it had a record year last year and is up 24% so far in 2026.

The Strait of Hormuz: The World’s Most Critical Chokepoint
In 2025, more than 14 million barrels per day flowed through the Strait of Hormuz. This made up one-third of global seaborne crude exports. About three-quarters of these barrels went to China, India, Japan, and South Korea. Any lasting disruption to this corridor could impact every major economy.
Capital Economics chief emerging markets economist William Jackson expects a prolonged conflict affecting supply could cause oil prices to jump to around $100, potentially adding 0.6–0.7 percentage points to global inflation.
Wall Street’s Worst-Case Scenarios
Major banks have already begun stress-testing their models. Wells Fargo strategists mapped out a sharp downside for equities: “In the event of prolonged Hormuz closure and an oil shock to $100+ per barrel, we forecast 6,000 on the S&P 500 as the worst-case scenario” — a near 13% decline from Friday’s close of 6,878.88. Still, Wells Fargo emphasized this is a tail risk, with its base forecast calling for the S&P 500 to reach 7,500 by the end of 2026.
Barclays analysts warned: “We would recommend not buying any immediate dip — risk-reward doesn’t seem compelling. If equities pull back enough, say over 10% in the S&P 500, there is likely a time to buy. But not yet.”
Defense Stocks: The Unlikely Winners
Not all sectors are suffering. Defense stocks have historically served as geopolitical hedges, and the current US-Iran conflict has proven no exception.
The iShares US Aerospace & Defense ETF has jumped 14% in 2026. The rally sped up significantly after hostilities began. Lockheed Martin shines, rising about 14.9%. Investors see growing demand for missile defence systems, fighter jets, and precision-guided munitions.

Aviation Chaos Adds to Economic Damage
Airlines cancelled hundreds of flights. Many were rerouted mid-flight due to closed airspace in the Middle East. On Saturday, over 1,800 flights to and from the region were cancelled. Qatar Airways stopped all flights. Emirates paused its service at Dubai International Airport. This airport is one of the busiest in the world.
Impact on Emerging Markets & India
For oil-importing countries like India, high crude prices pose risks. These risks include inflation, fiscal balance problems, and fears about rate cuts. Regional exchanges also took direct hits — Kuwait’s stock exchange suspended trading, while the UAE’s Capital Market Authority announced that trading on the Abu Dhabi and Dubai stock markets would be suspended for multiple days as a precautionary measure.
What Comes Next?
Conflict in the Middle East has shifted from a fringe risk to a major concern for investors. They worry about a power struggle in Iran and a long regional war. This situation could affect global trade and inflation.
Some analysts remain cautiously optimistic. Ed Yardeni, president of Yardeni Research, said: “We wouldn’t be surprised if any selloff in the S&P 500 on Monday morning turns into a rally, driven by expectations of lower oil prices once the latest Middle East war ends.”
The consensus is clear: volatility will dominate the coming weeks, and the durability of the energy shock — not just the headlines — will determine how deeply global markets are wounded in 2026.
