Seoul: The persistent decline of the Korean won against the U.S. dollar has escalated beyond ordinary fluctuations, signaling a deeper imbalance that Seoul's policymakers can no longer overlook. With the won trading consistently near the 1,470 mark, and discussions of reaching 1,500 becoming plausible, this situation reflects a structural reshaping of foreign exchange equilibrium that poses risks of eroding stability, triggering cost-push inflation, and unsettling crucial industries.
According to Yonhap News Agency, despite South Korea's substantial trade surpluses this year-with exports exceeding imports by approximately $56.4 billion and a current account surplus of about $82.8 billion-there is still a noticeable demand for dollars driven by factors outside of trade. The country's foreign exchange reserves were ample at about $428.8 billion at the end of October, yet the demand for dollars outpaces supply due to capital flows and changing corporate and household behaviors.
Key developments include a significant outflow of capital due to increased overseas investments by Korean residents, creating a demand for dollars that often surpasses the monthly trade surplus. Last month alone, retail investors bought about $6.8 billion in U.S. stocks. Additionally, foreign investors have been net sellers of Korean equities, selling approximately 9 trillion won ($6.1 billion) this month, which has intensified the demand for dollars. These sales reflect concerns over an AI valuation bubble and broader global risk aversion.
Global forces further amplify these domestic shifts, as the strengthening U.S. dollar, in light of adjusted expectations regarding Federal Reserve rate cuts, and a weaker yen, contribute to the won's depreciation. In this context, Korea's relative yield position and the prospect of further outward investment maintain persistent demand for dollars, resulting in a structural rather than episodic depreciation of the won.
The immediate consequences are significant, with imported energy and raw materials becoming more expensive in won terms, leading to an increase in consumer prices. Given Korea's reliance on imports for coal, oil, and numerous industrial inputs, a strong dollar likely raises production costs across sectors such as refining, steel, chemicals, food, and aviation. Companies with tight margins and limited ability to pass on costs in a subdued domestic market are already experiencing profit compression.
Policymakers face a challenging environment where verbal intervention and discussions with key market participants may help moderate volatility, but cannot address the structural causes. Aggressive fiscal easing or premature monetary policies aimed at stimulating growth could exacerbate the dollar shortage and increase imported inflation, necessitating fiscal prudence as part of the response.
In the long term, Korea needs supply-side strategies to raise domestic returns and reduce dependence on imported inputs. Supporting corporate hedging, broadening foreign exchange liquidity sources, and assisting small and medium-sized enterprises are crucial steps for mitigating import price shocks. Authorities must also maintain strategic coordination with major foreign exchange players, such as the National Pension Service, to manage dollar supply effectively and restore market confidence.
The decline of the won reflects a transformation in Korea's external finances that requires acknowledgment and action from policymakers. Failing to address these issues could lead to higher inflation, weaker consumption, and limited policy options. Restoring confidence necessitates measured intervention, clearer fiscal discipline, and structural reforms to enhance Korea's capacity to earn and retain foreign currency, thereby addressing the deeper shifts and turning the warning light back to green.
