South Korea Tightens Crypto Oversight: New Registration Rules and 2027 Tax Loom

Context The amendment to the Foreign Exchange Transactions Act creates a new “virtual‑asset transfer service” category, putting exchanges, custodians and other cross‑border crypto firms under finance‑minister oversight. This move follows a year‑long push to bring overseas virtual‑asset flows into the country’s foreign‑exchange monitoring system.

Key Facts - Firms that shift crypto assets between South Korea and foreign countries must register with the finance minister (Fact 1). - The Travel Rule, which currently applies to transfers above 1 million won, could be expanded to every crypto transfer, potentially adding verification steps and delays for exchanges (Fact 2). - Beginning January 1 2027, gains exceeding 2.5 million won (about $1,900) will face a combined 22% tax – 20% national income tax plus 2% local tax (Fact 3).

What It Means For traders, the registration requirement adds a compliance layer for any service moving assets overseas, while broader Travel Rule checks could slow down withdrawals and deposits during volatile periods. The upcoming tax will affect holders with sizable profits, prompting early planning for 2027 liabilities. Market reaction was muted: Bitcoin (BTC) traded at $27,300, down 3.2% on the day, with a market cap near $530 billion; Ethereum (ETH) sat at $1,800, down 2.8%, market cap around $215 billion.

Watch for how exchanges implement the new registration process and whether the Travel Rule expansion leads to measurable delays in cross‑border flows as the 2027 tax deadline approaches.
