South Korea's Crypto Tax Enforcement and Its Impact on Institutional Adoption

South Korea's 2025 cryptocurrency tax enforcement and regulatory reforms have positioned the country as a pivotal player in the global digital asset landscape. By introducing a 20% capital gains tax on profits exceeding 2.5 million KRW (approximately $1,795) and aligning with international financial standards, the government has created a structured environment that balances innovation with oversight. This regulatory clarity is proving to be a catalyst for institutional adoption, as evidenced by the phased rollout of investment guidelines and the emergence of stablecoin-driven liquidity.
