The Won’s Paradox: Structural Imbalances in a High-Performance Economy

Executive Summary

South Korea’s economy presents a study in contrasts: robust export performance and AA- credit ratings coexist with a persistently weak currency and capital flight. The U.S. Treasury’s re-designation of Korea as an exchange rate monitoring country—while absolving it of currency manipulation—spotlights structural vulnerabilities that defy traditional macroeconomic narratives. This tension between strong fundamentals and market dislocations reveals deeper challenges in capital allocation, industrial concentration, and geopolitical positioning that will define Korea’s economic trajectory.

Structural Capital Exodus Undermining Currency Stability

The won’s 15% depreciation against the dollar since 2024, deemed “inconsistent with fundamentals” by U.S. authorities, stems not from policy failure but structural capital flight. Private portfolio outflows doubled to $107 billion in 2024-2025, driven by:

• Retail investors (“Seohak ants”) chasing higher returns in U.S. equities
• Institutional frustration with domestic market limitations: conglomerate-dominated industries, sub-1x PBR ratios, and dividend yields trailing global peers by 2-3 percentage points

While the Bank of Korea’s $7.3 billion FX intervention and expanded NPS swaps temporarily stabilized markets, these measures address symptoms rather than causes. As BOK Governor Lee Chang-yong noted, the “poverty in abundance” paradox—strong export dollar earnings trapped offshore by bearish expectations—highlights a crisis of confidence in domestic capital deployment.

Semiconductor Supremacy Veils Industrial Fragmentation

Korea’s 0.5% industrial production growth in 2025 masks a K-shaped divergence:

• Semiconductors (+13.2%) and shipbuilding (+23.7%) powered by global tech demand and Chinese supply chain diversification
• Construction collapse (-16.2%), worst since 1998, as property markets buckle under 7% mortgage rates
• Non-semiconductor manufacturing contraction (-0.1%) exposing overreliance on cyclical sectors

This bifurcation complicates monetary policy: rate cuts needed for construction revival could exacerbate won weakness and imported inflation (currently at 3.8%), while hikes risk strangling the tech golden goose.

The Fiscal Tightrope: Growth Ambitions vs. Debt Realities

Fitch’s maintained AA- rating underscores Korea’s fiscal credibility but warns of debt sustainability risks as public debt/GDP approaches 60% by 2026. The dilemma:

1. Stimulus required to counter construction slump and boost non-tech sectors
2. Constitutional debt ceiling (60% of GDP) limiting response capacity
3. Demographic headwinds (working-age population -0.8% CAGR) pressuring pension liabilities

The NPS’s $765 billion portfolio, now pivotal in currency stabilization via FX swaps, faces conflicting mandates—propping up markets versus generating returns for aging beneficiaries.

Geopolitical Crosscurrents: Between Tariffs and Tech Wars

Trump’s renewed tariff threats (“could be much steeper”) and U.S.-China currency tensions place Korea in a strategic vise:

• 25% alleged yuan undervaluation pressures competitive positioning of Korean exports
• Semiconductor dominance attracts both U.S. investment demands and Chinese import substitution pushes
• BOK’s predicted forex market reforms within 3-6 months must navigate Treasury scrutiny and domestic capital flight

Conclusion: The High-Wire Act of Structural Reform

Korea’s economic managers face a trilemma: stabilize the currency without capital controls, diversify growth beyond semiconductors without fiscal profligacy, and navigate U.S.-China tensions without sacrificing export competitiveness. Success requires:

• Corporate governance reforms to boost domestic equity appeal
• Strategic FDI incentives in AI/EV sectors to broaden industrial base
• Coordination with Japan on stabilizing regional FX markets

Failure risks cementing Korea’s status as a perpetual “strong fundamentals, weak currency” economy—a cautionary tale of how structural rigidities can undermine macroeconomic vitality.
