As tensions in the Middle East soared following the joint US and Israeli military operations against Iran over the weekend, global financial markets responded with a striking shift in investor sentiment. On March 3, 2026, South Korea’s stock market provided a vivid snapshot of these reverberations, with defense and energy stocks surging while technology and automotive giants faltered, according to reporting from Money Today Broadcasting, Opinion News, and Seoul Economic Daily.
The immediate trigger for the market’s volatility was the US and Israel’s military assault on Iran, which, as reported by Seoul Economic Daily, resulted in the deaths of top Iranian officials, including Supreme Leader Ayatollah Ali Khamenei. Iran quickly retaliated, launching ballistic missile and drone attacks against US military bases and Israeli targets in the region. The prospect of further escalation sent shock waves through global investment circles, stoking fears of prolonged instability and supply chain disruptions.
These geopolitical tremors were felt acutely in South Korea’s pre-market trading. As of 8:17 AM on March 3, Samsung Electronics and SK Hynix, two of the nation’s tech heavyweights, saw their share prices drop by 2.08% and 2.26% respectively, according to Money Today Broadcasting. Other major stocks, including Hyundai Motor (-2.97%), LG Energy Solution (-3.51%), SK Square (-2.79%), Samsung Biologics (-2.59%), Kia (-3.21%), and Doosan Enerbility (-2.26%), also experienced declines. The weakness in these blue-chip stocks reflected a broader global retreat from risk, as investors braced for the economic fallout of heightened Middle East conflict.
Yet, amid the gloom, defense companies emerged as the day’s clear winners. Hanwha Aerospace, South Korea’s flagship defense contractor, saw its shares skyrocket by as much as 11.30% in early trading, reaching 1,327,000 KRW at 8:18 AM, as reported by Opinion News and Seoul Economic Daily. Other defense stocks followed suit: LIG Nex1 soared 14.93% to 585,000 KRW, Hyundai Rotem jumped 11.93%, and Korea Aerospace Industries (KAI) gained 8.36%.
The surge was fueled by a rush of investment into the defense sector, as investors anticipated that the expansion of geopolitical risk would drive up demand for military hardware. "The mention of a blockade of the Strait of Hormuz sent international oil prices soaring, increasing inflationary pressure," noted Seo Sang-young, an analyst at Mirae Asset Securities, in Money Today Broadcasting. He added, "The US 10-year Treasury yield rose by more than 8 basis points, which is also weighing on emerging market stocks."
Energy stocks, too, enjoyed a moment in the sun. S-Oil, a major South Korean refiner, surged 27.27% to 140,000 KRW, while SK Innovation climbed 13.94% and Kumho Petrochemical advanced 3.98%. The spike in oil prices, triggered by fears of supply disruptions in the Persian Gulf, provided a windfall for these companies. Meanwhile, on Wall Street, Nvidia bucked the broader downward trend with a 2.99% gain, but the positive momentum failed to lift Korean tech stocks, which remained mired in red.
Market watchers were quick to draw parallels with previous Middle East conflicts. Han Ji-young, an analyst at Kiwoom Securities, observed, "During past Middle East wars, stock markets initially fell but recovered over time." She added, "Given the learning effect, as well as governments’ ability to respond—such as the Korean government’s 100 trillion KRW liquidity support—and the possibility of oil-producing countries increasing output, this geopolitical crisis is unlikely to trigger a fundamental shift in market trends."
Looking beyond the immediate market reaction, the crisis is widely expected to reshape the global defense industry. Hana Securities, in a report released on March 3, predicted that even if the current conflict is resolved quickly, ongoing threats from Iran and persistent regional uncertainty will drive Middle Eastern countries to ramp up their defense spending and weapons imports. Many South Korean defense firms already have a strong foothold in the region, exporting advanced military systems to Middle Eastern buyers.
Hanwha Aerospace, in particular, stands to benefit from this shifting landscape. According to Biz Tribune, Korea Investment & Securities projected that Hanwha Aerospace would rapidly expand its European market share with its multiple launch rocket system (MLRS) known as Chunmoo. France is currently considering Chunmoo as a top candidate to replace its aging MLRS fleet, with the French Institute of International Relations (IFRI) describing Chunmoo as "the most balanced choice."
Chunmoo’s competitive edge lies in its rapid delivery and operational flexibility. Jang Nam-hyun, an analyst at Korea Investment & Securities, explained, "Chunmoo’s lead time is under two years, uniquely enabling delivery by 2027." This is a crucial advantage for France, whose existing equipment will soon be obsolete. Furthermore, Chunmoo’s open platform allows integration of ammunition from other countries, unlike US or Israeli systems that maintain strict controls. This operational openness has been highly praised, especially as more European countries—including Poland, Estonia, and Norway—adopt Chunmoo, boosting interoperability across the continent.
Hanwha Aerospace is also planning to build a missile production facility in Poland, enabling regional sourcing of ammunition and deepening its presence in the European market. The total export market for replacing aging M270 series and Soviet-era platforms in Europe is estimated to exceed 12 trillion KRW. With a diversified product portfolio—including the K9 self-propelled howitzer, Chunmoo, Redback armored vehicles, and propellant—Hanwha Aerospace’s 2026 export pipeline is projected to surpass 35 trillion KRW.
The company’s global ambitions extend beyond defense. On March 3, Hanwha Aerospace and US-based Venture Global (NYSE: VG) announced a landmark sales and purchase agreement. Under this deal, Hanwha Aerospace will buy 1.5 million tonnes of US liquefied natural gas (LNG) annually for 20 years, starting in 2030. This agreement expands Venture Global’s long-term contract portfolio to over 46 million tonnes per annum and marks its first long-term supply contract in Korea. Venture Global CEO Mike Sabel expressed pride in the partnership, stating, "This is another important step in expanding stable, long-term LNG supply to our Asian partners." He added, "We are proud to further strengthen the strategic energy partnership between the US and Korea, supporting long-term industrial and economic growth with secure, low-cost US LNG."
As the dust settles from the latest Middle East flare-up, South Korea’s defense and energy sectors find themselves in a rare position of strength, buoyed by global demand and strategic partnerships. For investors and policymakers alike, the events of March 3, 2026, will serve as a reminder of how swiftly the tides can turn—and how opportunity can emerge even in the midst of crisis.
