South Korea’s Foreign Currency Deposits Plunge to Record Low Amid Won Volatility

Seoul, South Korea – South Korea witnessed an unprecedented exodus from foreign currency deposits in March as corporations rushed to convert dollar holdings into the weakening won, signaling growing anxiety over exchange rate instability and its impact on the nation’s trade-dependent economy.

Sharpest Decline on Record

According to Bank of Korea data released this week, foreign currency deposits held by residents—including companies and individuals—plunged by $7.96 billion in March, the steepest monthly drop since records began in 1999. The total pool shrank to $85.8 billion, marking a stark reversal from February’s $1.3 billion increase. Analysts attribute the flight to the won’s dramatic depreciation, which slid nearly 3% against the U.S. dollar in March amid global risk aversion and Federal Reserve rate hike expectations.

“The scale of this withdrawal reflects corporate South Korea’s defensive maneuvering,” said Park Jeong-woo, an economist at KB Securities. “Exporters are bracing for prolonged currency turbulence by locking in dollar revenues now rather than risking further erosion of their won value.”

Won Weakness Triggers Corporate Exodus

The Korean won, Asia’s worst-performing currency this year after the Japanese yen, has been battered by a resurgent greenback and geopolitical tensions in the region. With over half of South Korea’s foreign currency deposits held by exporters—including tech giants like Samsung and Hyundai—the mass conversion underscores concerns about profitability. A weaker won, while traditionally boosting export competitiveness, now threatens to inflate import costs for critical energy and raw materials, exacerbating inflationary pressures.

“Companies are caught in a vicious cycle,” noted Hana Bank currency strategist Kim Hyun-ki. “They need dollars to settle imports but face mounting pressure to liquidate dollar assets as hedging costs rise. This selloff may intensify if the Fed delays rate cuts.”

Global Context: Dollar Dominance and Regional Ripples

South Korea’s deposit drain mirrors broader emerging-market strains as the U.S. dollar tightens its grip. The Bloomberg Dollar Spot Index climbed 2.7% in Q1 2024, pressuring currencies from the Thai baht to the Indian rupee. Neighboring Japan has intervened to prop up the yen, while China’s yuan hit five-month lows—a trend that could further destabilize regional exchange rates.

For South Korea, which relies on exports for 40% of its GDP, the stakes are particularly high. The nation’s foreign reserves, while substantial at $419 billion, have dipped for two consecutive months, raising questions about policymakers’ capacity to smooth volatility.

Policy Dilemmas Mount

The Bank of Korea faces a precarious balancing act. After hiking rates to 3.5% in 2023 to combat inflation, policymakers now confront slowing growth and household debt exceeding 100% of GDP. Analysts say further rate increases to defend the won could stifle consumption, while intervention risks depleting reserves.

“Authorities may need to jawbone markets or impose capital flow measures if this accelerates,” warned Standard Chartered’s Chong Hoon Park. During the 2008 crisis, Seoul introduced dollar liquidity guarantees to calm markets—a tool that remains on the table.

Long-Term Risks and Sectoral Strains

The deposit slump also exposes vulnerabilities in specific industries. Small manufacturers with dollar-denominated loans now face steeper repayment burdens, while airlines and energy importers grapple with soaring fuel costs. Meanwhile, retail investors who piled into overseas assets during the pandemic are retreating, with offshore equity purchases falling to a four-year low.

Economists caution that prolonged dollar strength could force painful adjustments. “If corporations continue repatriating funds, it may strain domestic dollar liquidity and push borrowing costs higher,” said Citigroup’s Kim Jin-wook.

Looking Ahead

With U.S. interest rates likely to stay elevated and Middle East tensions fueling safe-haven dollar demand, South Korea’s currency woes may persist. The government has signaled readiness to act, with Finance Minister Choi Sang-mok vowing to “respond sternly to excessive herd behavior.” Yet markets remain skeptical: credit default swaps on Korean sovereign debt have widened to November 2023 levels, reflecting growing investor unease.

As the global dollar squeeze tests emerging economies worldwide, South Korea’s record deposit drop serves as a stark reminder of the trade-offs between currency stability and economic growth. For now, businesses and policymakers alike are bracing for more turbulence ahead.
