South Korea Declares Martial Law: Impacts on Economy and Markets

• 7 min read

South Korea’s martial law declaration rattles markets, with the won hitting a two-year low. Key sectors, including exports and consumer goods, face heightened risks amid political uncertainty. Investor confidence wanes as capital outflows and slowed growth threaten stability. Defense stocks, however, may see gains, reflecting increased government focus on security. The declaration of martial law by South Korean President Yoon Suk Yeol marks a pivotal moment for the nation, introducing significant political and economic challenges. While the move aims to address alleged anti-state threats, it has triggered substantial market volatility, with the won plunging to a two-year low. The stock market, heavily reliant on foreign investment, faces potential outflows, impacting sectors like exports, consumer goods, and manufacturing. Meanwhile, South Korea’s economic fundamentals, including slowing exports, subdued consumer confidence, and a downgraded growth outlook, remain under pressure. This development poses risks to investor confidence and long-term economic stability. Martial Law Declaration South Korean President Yoon Suk Yeol declared martial law in a nationally televised address, citing threats to constitutional order and national security. The move, he argued, was necessary to combat opposition efforts to destabilize governance and address “anti-state elements.” The liberal opposition Democratic Party has strongly opposed the declaration, signaling potential political unrest. This drastic measure marks the most severe political action during Yoon’s presidency, highlighting tensions in a divided parliament.

The South Korean won has weakened to 1,427.10 per USD, its lowest level in over two years. This steep depreciation indicates capital flight as foreign investors reassess risks in the face of political uncertainty. South Korea’s stock market, heavily reliant on foreign participation (accounting for approximately 30% of market capitalization), is particularly vulnerable to these dynamics. Prolonged outflows could exacerbate declines in equity prices, further straining market stability. Sectoral ImpactsConsumer and Retail StocksConsumer and retail-focused sectors are expected to face headwinds due to declining consumer confidence. The Consumer Confidence Index has already slipped below the neutral mark, at 96.4 in October 2024, reflecting diminished household spending power. Major retail companies like Lotte Shopping and Shinsegae could see declining revenues as discretionary spending contracts. September retail sales fell 1.2% year-on-year, a trend likely to worsen amid ongoing unrest. Export-Oriented CompaniesSouth Korea’s export-heavy economy, with exports contributing approximately 40% to GDP, is particularly sensitive to disruptions. Political instability adds to existing trade challenges with major partners like China (20% of South Korea’s exports) and the United States (14%). Key exporters, including Samsung Electronics and Hyundai Motors, may face supply chain bottlenecks and reduced demand as trade relations come under strain. In October 2024, exports declined by 7.2% year-on-year, and further reductions could have ripple effects across dependent sectors like manufacturing and logistics. Defense and Security StocksIn contrast, defense-related sectors may benefit from the government’s focus on national security under martial law. Companies like Hanwha Defense and LIG Nex1, which produce advanced military technology, could see speculative inflows. Increased government spending on defense is likely as the administration seeks to project stability and strength, bolstering short-term demand for these stocks. Economic Context Export DependencyExports account for approximately 40% of South Korea’s GDP, making the economy highly sensitive to global trade dynamics. In October 2024, exports contracted by 7.2% year-on-year, reflecting weakening demand from key partners like China (South Korea’s largest trading partner, with 20% of export volume) and the United States (14% of exports). The semiconductor industry, which constitutes about 20% of total exports, witnessed a steep decline due to global oversupply and falling prices. Monetary Policy and InflationThe Bank of Korea (BoK) recently implemented an interest rate cut, lowering its base rate to 3.25% to support the flagging economy. This move reflects growing concerns over domestic economic performance. Inflation has eased significantly, with the consumer price index (CPI) growth slowing to 1.3% in October 2024, well below the BoK’s target of 2%. However, subdued inflation may also indicate sluggish demand, a worrying sign for long-term growth prospects. Growth ForecastsThe BoK revised its GDP growth forecast for 2024 to 1.9%, down from earlier projections of 2.2%, amid declining industrial output and muted investment activity. Gross fixed capital formation, a measure of investments, grew by just 0.8% in Q3 2024, highlighting limited private sector expansion. Industrial production fell by 2.6% year-on-year in September, with key sectors like manufacturing and construction reporting continued weakness. Consumer ConfidenceConsumer sentiment remains fragile, with the consumer confidence index (CCI) slipping to 96.4 in October 2024, below the neutral threshold of 100, indicating pessimism. Weak retail sales, which declined 1.2% year-on-year in September, further underscore reduced household spending power. Global and Regional ImplicationsPresident Yoon’s declaration underscores the geopolitical and economic vulnerabilities of South Korea. Regionally, it raises concerns about stability in a volatile East Asian environment, especially given its proximity to China and strained relations with North Korea. Globally, investors are weighing the long-term consequences of martial law on South Korea’s democratic image and its integration into global markets. Medium-Term Concerns The declaration of martial law in South Korea introduces significant medium-term risks for its stock market and economy. Policy uncertainty looms large, as martial law may further delay critical reforms and hinder effective governance, compounding issues caused by legislative gridlock in an opposition-controlled parliament.Capital outflows are a pressing concern, as political instability tends to drive foreign investors away. South Korea’s currency, the won, could face continued depreciation, increasing import costs and straining market stability. Persistent outflows could also deepen stock market losses, eroding investor sentiment further.Investor confidence in South Korea’s stability as a democratic and economically vibrant nation is at risk. The move tarnishes the country’s reputation, potentially deterring multinational corporations and long-term investors. Companies with significant operations in South Korea may reevaluate their risk exposure, while domestic firms might hold back on investments, stifling growth. Consumer confidence, a key driver of domestic demand, could also weaken amidst
