Woofun AI reports that South Korean authorities have executed a stringent crackdown on digital asset crimes, resulting in near-universal convictions for violations of the Foreign Exchange Transactions Act.

The aggregate scale of illicit activity reached 3.1 trillion won, equivalent to $2.2 billion, across 52 criminal cases. The dominant vector for these offenses involved using digital assets to mediate illegal exchanges between the Chinese yuan and the South Korean won, which accounted for 17 of the analyzed cases.

Secondary crime vectors included illegal remittances tied to Vietnam (13 cases) and activities linked to the Philippines and casino-related operations (seven cases each). Another seven cases targeted the "kimchi premium" price gap, while four additional cases involved gift certificates, duty-free goods, "suitcase traders," and XRP exchange violations.

Among the 95 defendants—comprising 93 individuals and two corporations—only one was acquitted.

Woofun AI data shows that of the 94 convicted, 46 (48.9%) received suspended prison terms, 28 (29.7%) were fined, 19 (20.2%) received prison sentences, and one (1.0%) received a suspended sentence for a fine.

This 99% conviction rate underscores the rigorous legal framework established to combat the use of digital assets in foreign exchange violations. Prosecutors are increasingly focusing on how cryptocurrencies bypass controls on cross-border capital movements, particularly exploiting arbitrage opportunities created by the kimchi premium for illegal fund transfers.

The combination of $2.2 billion in illegal swaps and a 99% conviction rate demonstrates South Korea’s firm regulatory posture. As digital asset adoption expands, other jurisdictions may adopt this enforcement model to curb illicit financial flows.
