South Korea Tightens Digital Asset Exchange Withdrawal Rules to Fight Voice Phishing

South Korea's financial authorities are taking decisive action to curb the growing threat of voice phishing by bolstering withdrawal delay systems at digital asset exchanges. Recognizing that vague exception criteria have allowed fraudsters to continue exploiting these platforms, regulators, in collaboration with the Digital Asset Exchange Alliance (DAXA) and individual exchanges, have developed a unified standard for these regulations. This move is crucial for protecting citizens from sophisticated financial scams where stolen funds are rapidly converted into digital assets and moved across platforms or to private wallets.

The current system, established in May 2025, imposes initial 72-hour withdrawal restrictions for new fiat deposits and 24-hour limits for subsequent deposits. However, a significant loophole has been the inconsistent and often lenient application of exception criteria across different exchanges. Some exchanges have granted exceptions based on trading history or membership status alone, while others have considered factors like transaction frequency or solely the amount of financial misconduct. This inconsistency has been exploited by criminals who establish accounts and meet these lax standards to quickly move illicit funds.

Data reveals the severity of the problem: between June and September 2025, 59% of voice phishing cases, amounting to 170.5 billion won (approximately $125 million USD), originated from accounts granted withdrawal exceptions. The new standard regulations aim to rectify this by clearly defining criteria based on transaction frequency, duration, and deposit/withdrawal amounts, along with stricter conditions for exceptions and enhanced monitoring of affected accounts. While this may introduce minor inconveniences for some legitimate users, the primary goal is to significantly reduce voice phishing damages and bolster the overall trust and integrity of South Korea's digital asset market.
