Financial markets worldwide are preparing for potential widespread disruption as Middle East tensions escalate beyond what investors initially anticipated, according to market analysts.
What began as a peripheral concern has now evolved into a primary source of anxiety for Wall Street, particularly following weekend U.S.-Israel military operations that resulted in the death of Iranian Supreme Leader Ayatollah Ali Khamenei on Saturday. The strikes prompted Iranian retaliation against Gulf cities, forced airlines to cancel flights, and led to the suspension of oil tanker traffic through the crucial Strait of Hormuz.
Market experts are particularly concerned about the unpredictable nature of Iran’s political future, given the complex structure of the Islamic Republic’s government, its ideological foundation, and the influence wielded by the Revolutionary Guards.
These uncertainties are creating additional pressure on oil markets, which have already experienced weeks of price increases and now face potential disruption based on regional producer actions and shipping lane accessibility. The situation carries significant implications for global inflation rates and could even impact traditionally safe investment bonds.
Rong Ren Goh, a portfolio manager with Eastspring Investments’ fixed income division in Singapore, explained the market shift: “Middle East tail risks have increased. Markets will reprice from geopolitical shock to regime risk shock, prolonged conflict, not just retaliation, unless Iran says it wants to negotiate.”
Market specialists suggest a major concern is investor overconfidence, with many assuming the economic impact will remain limited, similar to last June’s “12-Day War” in Iran or Russia’s ongoing attacks on Ukraine. Many are also dismissing parallels to Iran’s 1979 regime transformation.
Current market indicators show Brent crude oil has risen by 20% this year, reaching approximately $73 per barrel. Investors have been purchasing U.S. Treasury bonds and gold as protective measures against various risks, including Middle East instability and unpredictable policies from President Donald Trump.
Gold experienced record performance last year and has gained 22% in 2026 so far, while the primary U.S. stock index has only increased by 0.5%.
Barclays analysts noted in a Saturday report: “History argues strongly in favor of selling geopolitical risk premium when hostilities start. What worries us is that investors have now learned this pattern and might be underpricing a scenario where containment fails.”
The Barclays team also highlighted additional factors that could worsen any market decline if conflict expands, including existing concerns about artificial intelligence market valuations and private credit sectors.
“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 to come a time to buy. But not yet,” the analysts advised.
Markets are expected to experience significant volatility in the upcoming week.
Charles Myers, chairman and founder of geopolitical investment consulting firm Signum Global Advisors, assessed the situation before the weekend strikes: “The markets are prepared for a limited surgical strike. What is not priced in is a major strike to decapitate the regime.”
William Jackson, chief emerging markets economist at Capital Economics, predicts that extended conflict affecting supply chains could push oil prices to around $100, potentially increasing global inflation by 0.6-0.7 percentage points.
Tariq Dennison, a wealth adviser at Zurich-based GFM Asset Management, offered a different perspective: “In my view, the market has already been overestimating inflationary forces, so I don’t think this will change much. There will be more impact on Europe than U.S. given the closer proximity of Hormuz oil and gas post-Russia.”
Dennison also noted: “Maybe a slight short term uptick on gold, but gold has already priced in maximum geopolitical uncertainty.”
Eastspring’s Goh pointed to the continuous decline in U.S. bond yields, which has brought 10-year rates below 4%.
“I’m not sure if buying US Treasuries here is a good trade, especially if oil prices spike and induce inflation, if this thing drags,” he stated.
However, some market observers believe Iran will be unable to significantly disrupt Gulf region commerce and that oil price impacts will remain manageable.
Ed Yardeni, president of New York-based Yardeni Research, suggested: “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 price of gold might also round-trip on Monday. Bond yields might fall due to both safe-haven demand and post-war prospects for lower oil prices,” Yardeni added.
