On March 3, 2026, South Korea’s financial markets awoke to a jolt that echoed far beyond the country’s borders. As trading opened in Seoul, the won-dollar exchange rate surged to 1,462.3 won per dollar—an increase of 22.6 won from the previous day—breaching the 1,460-won threshold for the first time since early February. The culprit? Escalating military conflict in the Middle East, with the United States and Israel launching airstrikes on Iran, and Iran responding in kind. The global financial community braced for turbulence as risk aversion swept across major markets, sending investors scrambling for safe havens like the US dollar and gold.
According to Yonhap News Agency, the sudden spike in the won-dollar rate was driven by mounting geopolitical risks after the death of Iran’s Supreme Leader and a string of retaliatory airstrikes. The Iranian Revolutionary Guard Corps tightened control over ships navigating the critical Strait of Hormuz—a bottleneck for world oil supplies—prompting some global shipping giants to suspend or delay operations. As concerns mounted over possible disruptions to oil supply, international oil prices climbed sharply, adding fuel to inflationary fears and pushing investors toward the perceived safety of the dollar and gold.
These developments set the stage for classic market dynamics: as Business Post pointed out, “geopolitical risks have increased demand for safe-haven assets and pushed up international oil prices, fueling inflation concerns and strengthening the dollar.” The US Dollar Index, which measures the greenback’s value against a basket of major currencies, jumped from the mid-97 range before the Iran conflict to the mid-98 range after, while the yen weakened to over 157 yen per dollar. Gold prices, too, soared past $5,300 an ounce internationally and surged more than 4% domestically in South Korea, with prices exceeding 250,000 won per gram.
The impact was immediate and widespread. On the first trading day after the US and Israeli attacks, the won-dollar rate hovered around 1,460.5 won, as reported by Kyunghyang Shinmun. This wasn’t the first time in recent months that the rate flirted with such highs—back in January, it had touched 1,480.4 won—but the current spike was directly tied to the sudden escalation in the Middle East. In the words of KB Securities analyst Oh Jae-young, “If the US-Iran military conflict lasts more than one month, the won-dollar exchange rate could rise again to around 1,480 won.” He added, “If the conflict ends within one month, the dollar is expected to rise temporarily then decline; if prolonged, the dollar could remain strong throughout 2026.”
East Asia’s heavy reliance on oil imports only compounds the problem. As Oh further explained, “Korea and the broader East Asia region are highly dependent on oil imports, so sharp oil price rises could worsen trade and current account balances, further weakening the won.” In such a scenario, he warned, the won-dollar exchange rate could “re-enter the 1,480 won range.”
Meanwhile, the global financial markets were not immune to the shockwaves. The New York Stock Exchange’s Dow Jones Industrial Average closed down 521.28 points (1.05%) at 48,977.92 on March 2, 2026, as reported by Global Economic. The S&P 500 and Nasdaq Composite also dipped, by 0.43% and 0.92%, respectively. The sell-off extended to bank and asset management stocks, which plunged amid renewed credit concerns. The mood was further soured by a surprise jump in the US Producer Price Index (PPI) for January—up 0.5% month-over-month, exceeding forecasts and stoking inflation worries. The spike in PPI, especially in the services sector, was interpreted as a sign that companies were passing on higher costs to consumers, raising the specter of persistent inflation and complicating the Federal Reserve’s interest rate trajectory.
Risk aversion spread like wildfire. Major countries, including the US, UK, Canada, India, and China, issued evacuation advisories for their citizens and diplomats in the Middle East. China’s foreign ministry cautioned that “external security risks facing Iran have risen significantly,” urging its nationals to leave the country. The CBOE Volatility Index (VIX), a barometer of market fear, jumped 6.6% to 19.86.
Oil and gas markets were equally rattled. West Texas Intermediate (WTI) crude for April delivery surged about 8% to around $72 per barrel, while European natural gas prices spiked over 26%, topping 40 euros per megawatt-hour. The Strait of Hormuz, which handles about 20% of global LNG shipments and a third of China’s oil imports, was at the center of these anxieties. According to AP, if Iranian oil exports are disrupted, China may be forced to seek alternative suppliers, driving energy prices even higher. Russia, meanwhile, stands to benefit, as it ramps up discounted oil sales to India and China amid Western sanctions.
On the ground, the conflict was intensifying. Iran’s military launched missile strikes on US naval bases in Bahrain and Hezbollah fired rockets into Israel from Lebanon, all following the death of Supreme Leader Ayatollah Ali Khamenei. The US Central Command reported three American fatalities and five serious injuries as of March 1. President Trump, in a video address, vowed that military operations would “continue until all objectives are achieved.” In retaliation, Iran’s proxies expanded their attacks, turning the confrontation into a broader regional showdown.
Back in Seoul, the government wasted no time in responding. On March 3, 2026, South Korea’s finance authorities convened an emergency “Financial Market Situation Review Meeting,” bringing together the Ministry of Economy and Finance, the Bank of Korea, the Financial Supervisory Service, and other key institutions. They pledged 24-hour monitoring of market volatility and reaffirmed their readiness to deploy a market stabilization program worth “100 trillion won plus alpha” if needed. Officials also vowed a zero-tolerance approach to unfair trading practices, such as spreading false information or manipulating prices.
Support for the real economy was also on the agenda. With many small and medium-sized Korean exporters heavily exposed to Middle Eastern markets, major banks announced emergency liquidity support programs totaling tens of trillions of won. Hana Financial Group, for example, offered 12 trillion won in emergency funding and up to 500 million won in stabilization loans per affected company. KB Financial provided special interest rate discounts and facility loans, while Shinhan, Woori, and Nonghyup banks rolled out similar packages to help companies weather the storm.
Despite the turmoil, some experts see reasons for cautious optimism. Kim Doo-eon, a researcher at Hana Securities, noted that while the Iran crisis is a “risk-off variable” that could push the won-dollar rate toward 1,480 and trigger foreign outflows from Korean stocks, the shock may prove temporary. “The impact is likely to be short-lived, with a quick recovery possible,” he said, citing structural strengths such as robust semiconductor earnings and recent legal reforms favoring Korean equities. He added, “Bond yields are unlikely to rise much due to safe-haven demand, and the won-dollar rate should gradually stabilize around 1,430.”
Still, the consensus is that markets will remain on edge, sensitive to every headline and development out of the Middle East. Until the current geopolitical storm subsides, volatility is here to stay—and policymakers, investors, and businesses alike are bracing for whatever comes next.
