South Korean Banks Race Into Crypto as Overseas Users Abandon Traditional Remittance Rails

South Korea's crypto exchanges processed 163.55 trillion won ($125.8 billion) in cross-border payments in 2025. That total is up 380% from 2022 and surpassed the country's traditional bank transfers for the first time. The growth is tied to cheaper and faster transfers used by overseas workers and traders. Crypto transfers typically cost less than half of bank wire fees, and settlement times drop from days to minutes, industry data show.

Traditional banks face pressure to cut fees or lose remittance volume. Some of the biggest lenders have rolled out crypto custody and trading services. None have matched the price and speed of exchange-based transfers for cross-border use. Banks with heavy remittance exposure carry the clearest risk.

The 2025 figure is the highest on record for crypto in South Korea's payments system.
