South Korean lawmakers are pushing legislation that would expand the Financial Intelligence Unit's (FIU) authority over unregistered crypto firms, a move that would give regulators broader power to monitor and act against virtual asset operators working in the country without proper registration. The push fits into a wider tightening of South Korea's crypto oversight.

What the Legislation Would Change

The legislative effort centers on equipping South Korea's FIU with stronger oversight tools aimed specifically at crypto businesses that operate without registering under the country's virtual asset rules, according to reporting on the proposed bill.

The target is clear: unregistered crypto firms. Under South Korea's existing framework, virtual asset service providers are required to register with the FIU, and the proposal seeks to close the gaps around operators that fall outside that registration net. The measure focuses on unregistered virtual asset service providers rather than licensed exchanges alone.

That framework dates to amendments of the Act on Reporting and Using Specified Financial Transaction Information that took effect in March 2021, which require VASPs to register with the FIU and pair with a local bank for real-name customer deposit accounts. When the first registration deadline arrived in September 2021, dozens of smaller exchanges shut down rather than meet the conditions. The FIU, which operates under the Financial Services Commission as the country's anti-money-laundering supervisor, already polices registered firms, and the bill would aim its new tools at operators beyond that perimeter.

Why Regulators Are Focusing on Unregistered Firms

Unregistered status matters in financial regulation because operators outside the registration system sit outside the FIU's normal monitoring and anti-money-laundering reporting obligations. Expanded authority would allow the unit to reach firms that current rules do not fully cover, and the proposal signals that lawmakers see limits in existing enforcement tools.

South Korea has already moved on several fronts to tighten its regime, including lowering the travel rule threshold for crypto transfers — cut from 1 million won to 1,000 won in 2023 — and pressing exchanges toward stricter compliance. A user-protection law that took effect in July 2024 added custody, insurance and market-abuse obligations for licensed exchanges, and those duties bind registered operators rather than firms outside the system. The direction is consistent with regulators' broader stance. The country's Financial Services Commission has also advanced measures affecting exchange ownership and licensing, part of what officials describe as tighter market supervision, per the commission's regulatory notices.

What Broader FIU Powers Could Mean for the Market

For crypto businesses, broader FIU powers would raise compliance expectations. Firms currently operating without registration would face greater scrutiny and pressure to either register or exit the market.

The shift arrives alongside other structural changes to the sector, including a proposed 20% ownership cap for crypto exchanges and continued debate over a won-backed stablecoin framework. Together, these moves point to a market being steered toward tighter regulatory boundaries. The registered market those rules act on is also narrow: a small set of FIU-registered exchanges — including Upbit, Bithumb, Coinone, Korbit and Gopax — have been the only platforms with the real-name banking partnerships needed for full KRW trading, leaving most other registered operators without won deposit access.

Enforcement momentum has been visible elsewhere as well, including a 15-year sentence in a major South Korean crypto fraud case, underscoring how authorities are pairing rulemaking with prosecution.

The balance regulators face is a familiar one: stronger oversight can improve consumer protection and monitoring, but it also adds compliance burdens for operators. Local coverage has framed the FIU push within that ongoing tension over how far supervision should extend, as reported in South Korean media. Any expanded powers would still require passage through the National Assembly, sitting alongside the separate ownership-cap and stablecoin measures, which makes the legislative timetable and the exact tools the FIU ultimately receives the practical questions to watch.
