South Korea Leads East Asia With $449 Billion Crypto Economy Powered by AI Tokens

South Korea's digital asset economy reached $449.1 billion between July 2025 and June 2026, solidifying its rank as East Asia's largest crypto market, according to an annual regional report released by Chainalysis on Oct. 5, 2026 ¹. South Korea recorded 12.3% period-over-period growth, propelled by a 16.3% increase in its domestic centralized exchange ecosystem and retail trading focused on artificial intelligence-themed tokens ¹.

Regional runners-up included Japan at $228.3 billion, Hong Kong at $192.2 billion, China at $176.3 billion, and Taiwan at $140.4 billion ¹. Across East Asia, divergent domestic regulations shaped distinct trading behaviors ¹. In Hong Kong, institutional platforms accounted for 16% of service inflows—nearly three times the proportion in neighboring jurisdictions—with prime brokerages, market-making desks, and custody providers representing 85% of that activity ¹. In Mainland China, peer-to-peer stablecoin transactions saw active unique sender wallets climb 43-fold from the first quarter of 2024 to the second quarter of 2026 ¹.

Retail AI Bets and Impending Regulatory Shifts

South Korea's trading activity heavily favored AI tokens, echoing retail equity enthusiasm for semiconductor leader SK Hynix ¹. By June 2026, AI-linked cryptocurrencies represented the single largest thematic trading category by Korean won volume ¹. The won-denominated share of AI token transactions was 19.5 times higher than the equivalent market share in Japanese yen and sharply outpaced trading volumes recorded in euros, British pounds, and Brazilian reals ¹. Worldcoin ($WLD) led individual AI asset volumes in the jurisdiction at $7.41 billion, followed by $SAHARA with $3.2 billion, $VIRTUAL with $2.7 billion, $BIO with $2 billion, and $NEAR with $1.7 billion ¹.

Meanwhile, Japan distinguished itself via decentralized finance adoption, recording a 34.5% decentralized exchange (DEX) market share among service platforms ¹. Retail trades drove Japan's DEX engagement, with 65.7% of swaps falling within the $10 to $1,000 bracket ¹.

South Korea's retail dominance has been sustained by a tax-free regime, but policy shifts could alter market structure ¹. A 22% tax on crypto gains is scheduled for implementation at the start of 2027 following multiple postponements ¹. In parallel, domestic banks and securities firms have established digital asset units to pilot custody, tokenization, and stablecoin solutions after the Financial Services Commission presented an institutional onboarding roadmap in February 2025 ¹.
