South Korea’s Financial Services Commission (FSC) and Financial Supervisory Service (FSS), along with the Digital Asset Exchange Association (DAXA), are rolling out uniform rules for withdrawals across all registered cryptocurrency exchanges.
Unified crypto withdrawal system
From now on, all local cryptocurrency exchanges will be forced to follow a strict and uniform withdrawal delay system by South Korean financial regulatory bodies. According to what was reported by the Korean newspaper News1The goal of a new withdrawal delay system for cryptocurrency exchanges is to prevent damage from speed-based voice phishing.
The new criteria will be standardized for “delayed withdrawal exceptions”, which according to News1 were previously vulnerable to criminal exploitation. Intensive monitoring will also be conducted on accounts to which these exceptions apply.

The above vulnerability was created by “exchange-by-exchange vulnerabilities” exploited by scammers, The Korea Times claims. In many of these phishing schemes, dirty money is transferred into the account, then quickly converted into cryptocurrencies, and then quickly returned back before investigators can track it down or shut it down.
What change really entails
South Korean exchanges have been forced to suspend cryptocurrency withdrawals for 24 to 72 hours after a deposit since May 2025. This creates a buffer window that allows banks and regulators to detect and stop suspicious transfers. However, the rules include exceptions based on factors such as how long the account has been open, previous activity, trading volume, and any history of misconduct. Each exchange has developed and implemented these standards on its own so far.
In some cases, accounts slipped into the exempt group with minimal checks, allowing scammers to avoid the waiting period and withdraw funds almost immediately. Between June and September 2025, 59% of fraud-related exchange accounts identified were in these “exclusion” groups that avoided delays. Under the new standards, the authorities want to reduce exclusion accounts to less than 1% of users. Exchanges are also required to tighten their know-your-customer (KYC) policy, verify sources of funds and monitor those accounts
Regulators also plan to tighten scrutiny of exempt accounts, and roll out stronger and more frequent checks for customers. This includes routine verification of the source of funds, at least once a year. Alongside this, a new system designed to track and analyze withdrawal patterns more systematically will also be needed.
To keep inconvenience to a minimum, exemptions will still be available where there is a genuine need for immediate withdrawals, for example, to settle accounts.
Market effects
This new measure comes in addition to other stringent Korean encryption regulations recently issued, such as AI-powered transaction monitoring and possible early freezing of accounts of suspected manipulators. Just this Monday, the Financial Services Commission (FSC) ordered all local cryptocurrency exchanges to have a new 5-minute asset matching system.Regulators have found that the current kill switches of some major exchanges are unreliable.

All new users and large new deposits will face predictable “cooling off” windows of 24 to 72 hours before they can move coins to self-custody or offshore locations, dampening fast money flows and banking activity.
Uniform delays and stricter exemptions make it harder for scam rings to set up new accounts across multiple exchanges, but they also push experienced traders toward longer-term setups, derivatives on regulated venues, or non-Korean liquidity centers.
If the model succeeds and fraud metrics fail, Korea’s standardized delay model will likely emerge in other high-risk jurisdictions as a “best practice” for managing fraud-intensive retail flows.
