KOSPI's Meteoric Rise: Why South Korea Still Isn't a Developed Market

South Korea's KOSPI has been on an incredible ride, skyrocketing 112% in 2026. It's even managed to outpace the UK's FTSE 100, claiming the title of the world's top-performing major index in 2025. But despite these impressive feats, MSCI's recent review keeps the country firmly in the 'emerging markets' camp. Why?

The Currency Conundrum

Here's the crux of the matter: the Korean won. According to MSCI CEO Henry Fernandez, South Korea isn't lagging in economic or technological prowess. It's the won that's the real hurdle. For foreign investors, trading South Korean equities means dealing with the won, restricted to Seoul's business hours for trading. That's a dealbreaker when other developed markets offer 24-hour currency trading from any major financial hub.

This limitation isn't just a minor inconvenience. With a third of the world's index assets managed globally, funds can't rebalance their South Korean positions outside of Seoul's trading hours. It's like trying to catch a bus that only runs a few hours a day.

Is Change on the Horizon?

In a bid to address these concerns, South Korea plans to start 24-hour dollar-won spot trading from July 6. Fernandez acknowledges this as a genuine step forward. But will a night shift in Seoul deliver the liquidity and tight bid-ask spreads needed to satisfy institutional investors? He's skeptical, seeing the proposed reforms as a patch rather than a solution.

Beyond the currency issue, other barriers remain. MSCI points to strict investor ID requirements, limitations on in-kind transfers, and constraints on exchange data usage, which continue to frustrate investors. These factors collectively contribute to South Korea still being seen as an emerging market despite its economic achievements.

The Bigger Picture for Crypto

So, what does all this mean for the crypto space? The delay in South Korea's upgrade is a mixed bag. On one hand, investors seeking exposure to emerging markets might find solace in KOSPI's growth potential. On the other, the hesitancy of MSCI to reclassify South Korea might push local investors toward the flexibility and accessibility of crypto. Crypto remains a global market, available 24/7, with none of the won's constraints.

And then there's the matter of perception. If South Korea's market is considered an 'emerging' one despite its performance, could this boost the allure of digital assets perceived as more accessible and democratic? The crypto world thrives on inclusivity and constant availability, something the traditional markets in Seoul still struggle to provide.

Ultimately, the July trading launch will be a real test. If it succeeds in creating a deep, liquid market, MSCI's next annual review might paint a different picture. Until then, both traditional and crypto investors will be watching closely, weighing their options in a shifting market.
