KOSPI Up 85%. NIKKEI Up 22%. Nifty 50 Down 3%. What’s Really Driving Asia’s Market Divergence?

Everyone Thinks Asia’s Rally Is AI. They’re Missing the Real Story.

The recent outperformance of Asian equity markets — particularly Japan’s Nikkei and South Korea’s KOSPI — is largely being framed as an AI and semiconductor story.

That explanation is incomplete.

AI and the memory-cycle recovery have clearly driven earnings and index performance, especially in Korea through companies like SK Hynix and Samsung Electronics. SK Hynix shares have risen more than 120% over the past year as demand for HBM memory and AI infrastructure exploded globally. But the broader rerating of Japanese and Korean equities has also coincided with something deeper: a deliberate restructuring of capital-market architecture.

Japan’s Nikkei recently touched fresh multi-decade highs after the Tokyo Stock Exchange launched an unprecedented push for companies trading below 1x book value to improve ROE, unwind cross-shareholdings and increase shareholder returns. Nearly 50% of Prime Market companies had historically traded below book value. Japanese buybacks crossed record levels above ¥18 trillion in FY2025, while foreign investors poured more than $60 billion into Japanese equities over the last year. The result has been a broad rerating across banks, industrials, trading houses and holding companies — not just technology beneficiaries.

South Korea is now attempting a similar transition. Since launching its Corporate Value-up Program in 2024, the government has pushed phased English-disclosure mandates, governance reforms and capital-efficiency measures aimed at reducing the long-standing “Korea discount.” Foreign investors own roughly 30% of the KOSPI market, making governance credibility and disclosure quality critical drivers of capital flows. The rerating has similarly expanded beyond semiconductors into financials, industrials and conglomerate holding structures.

In both cases, markets are not just repricing earnings. They are repricing institutions.

India, however, faces a different challenge. Unlike Japan or Korea, India’s primary bottleneck is not entrenched governance opacity inside mature conglomerates. India’s larger opportunity lies in building the financial architecture required to absorb, compound and recycle capital at scale over the next two decades.

That means better structures for raising and exiting capital across both private and public markets, deeper domestic pools of long-duration risk capital, more efficient taxation frameworks, and regulatory systems designed for capital formation rather than friction management.
