MSCI Retains South Korea in Emerging Markets Over FX Hurdles

Global index provider MSCI has decided to keep South Korea within its emerging-market index, citing persistent challenges regarding market accessibility. Despite significant structural reforms initiated by the government, the index provider noted that the onshore foreign exchange market still falls short of developed-market standards.

The Foreign Exchange Bottleneck

The primary reason for MSCI's decision lies in the liquidity and structure of South Korea's foreign exchange (FX) market. According to the index provider, the Korean won remains a non-deliverable offshore currency, which presents a hurdle for large-scale international institutional investors.

Furthermore, MSCI highlighted that liquidity during extended onshore FX trading hours is currently inadequate to meet the rigorous execution standards expected in developed markets. While the index provider acknowledged the reforms introduced by South Korean authorities, it emphasized that investors need more time to evaluate whether these changes will lead to sustained, long-term improvements in market stability and access.

Government Reforms and the Path to Developed Status

The administration of President Lee Jae Myung has made achieving "developed-market" status a core policy objective. Since taking office in June 2025, the government has rolled out a series of ambitious market reforms to address the very issues cited by MSCI.

One of the most significant planned interventions is the introduction of round-the-clock foreign exchange trading, expected to launch in the second half of this year. South Korean finance ministry and regulatory officials have noted that the country’s exclusion from the developed-market watchlist this year was a reflection of the fact that these reforms are still in the implementation phase. Authorities remain optimistic that continued progress in capital market reforms will eventually pave the way for inclusion in the developed-market index.

KOSPI Performance Amidst Classification Setbacks

Despite the lack of a "developed" classification, South Korea's equity markets have shown remarkable resilience and growth. The benchmark KOSPI index has emerged as the world's best-performing equity benchmark over the past year. This surge was largely driven by massive gains in semiconductor stocks, fueled by the global explosion in artificial intelligence (AI) infrastructure investment.

The market has experienced significant volatility following the MSCI announcement. While the KOSPI tumbled nearly 10% in a single session—marking its steepest one-day decline since March—it managed a rebound of more than 3% shortly after. Analysts suggest that while the MSCI decision was largely anticipated due to weak performance across accessibility criteria, the underlying strength of the semiconductor sector continues to provide a cushion for Korean equities.

Key Takeaways

  • Accessibility remains the main hurdle: MSCI cited inadequate liquidity in the onshore foreign exchange market and the non-deliverable nature of the Korean won as key reasons for maintaining emerging-market status.
  • Major reforms are underway: The South Korean government is implementing round-the-clock FX trading and other capital market reforms to meet developed-market standards.
  • Strong fundamental growth: Despite the classification, the KOSPI has been a top global performer, driven primarily by the AI-led semiconductor boom.
