South Korea’s cryptocurrency landscape is undergoing a seismic shift. As regulatory pressure intensifies, a wave of exchange closures has swept across the nation, leaving only a few major players standing. With stricter compliance demands and heightened scrutiny from financial authorities, the future of digital assets in Korea is being redefined—not through unregulated trading, but through institutional-grade solutions like digital asset custody.
This transformation isn’t sudden. It’s the result of a months-long regulatory campaign aimed at bringing transparency, security, and accountability to one of Asia’s most active crypto markets.

The Regulatory Crackdown on Korean Crypto Exchanges
Since March 2025, South Korea has enforced sweeping changes under the revised Act on Reporting and Using Specific Financial Transaction Information. These regulations require all entities involved in virtual asset exchange, storage, and management to register with the Korea Financial Intelligence Unit (KoFIU) and comply with strict anti-money laundering (AML) and know-your-customer (KYC) standards.
The law, effective from March 25, includes severe penalties for non-compliance:
- Fines up to 100 million KRW (~$90,000)
- Suspension of operations
- Revocation of business licenses
A key rule prohibits exchange employees from trading on their own platforms—a move designed to eliminate insider advantages and market manipulation.
By August 1, the Financial Services Commission (FSC) had identified 11 mid-sized exchanges using fraudulent collective accounts, initiating plans to suspend their services and report them to law enforcement.
Timeline of Regulatory Actions
- March 25: Revised AML law takes effect, mandating registration with KoFIU.
- April 18: Government announces crackdown on crypto-related crimes, including money laundering and fraud.
- April 21: Customs Authority begins monitoring cross-border crypto transactions to combat "kimchi premium" arbitrage.
- April 22: Financial regulators ban internal staff from sharing or acting on crypto investment information.
- June 7: National Assembly considers legislation to criminalize market manipulation in crypto.
- June 16: Over 20 exchanges ordered to disclose delisted or high-risk tokens.
- August 1: Enforcement escalates—11 exchanges face shutdowns.
These coordinated actions signal a clear government intent: bring virtual assets into the formal financial system or remove them entirely.
Why Is Korea Tightening Crypto Regulations?
Three primary motivations drive this regulatory push:
1. Combatting Illicit Financial Activities
With crypto trading volumes surging in early 2025, concerns over money laundering and fraud have intensified. The anonymity once associated with blockchain transactions poses a risk to financial integrity. By enforcing real-name account systems—where users must verify identity through bank-linked accounts—Korea aims to close loopholes exploited by bad actors.
Only exchanges partnered with banks for real-name deposit and withdrawal services can operate legally. This requirement effectively filters out platforms unable to meet stringent compliance standards.
2. Enforcing Exchange Compliance Through Banking Ties
Under the new rules, exchanges must partner with traditional banks to offer verified accounts. However, most local banks are hesitant due to liability risks—if an account is used for illicit activity, the bank shares responsibility.
As a result, only four major exchanges—Upbit, Bithumb, Coinone, and Korbit—have secured these partnerships. The remaining ~100 smaller platforms have been forced to wind down operations as the six-month grace period expired.
3. Addressing Tax Evasion
Another critical driver is tax compliance. In early 2025, Korea’s National Tax Service revealed that 2,416 individuals were under investigation for evading taxes using cryptocurrency holdings—a figure that sparked national attention and media coverage.
To close this gap, regulators are ensuring that all crypto transactions leave a traceable, taxable footprint. By centralizing trading activity through regulated exchanges with real-name verification, authorities can better track capital gains and enforce tax collection.
Digital Asset Custody: A New Path for Korean Finance
While many exchanges face extinction, a new opportunity is emerging—digital asset custody.
Given legal restrictions preventing banks from directly offering crypto custody, Korean financial institutions are partnering with blockchain firms to enter the space indirectly.
This hybrid model allows banks to participate in the digital asset economy while mitigating regulatory and reputational risks.
Key Developments in Institutional Custody
- KB Financial Group, Korea’s largest bank, launched KODA (Korea Digital Asset) in late 2024 with blockchain leaders Haechi Labs and Hashed. KODA supports custody for Bitcoin, Ethereum, and KLAY.
- Shinhan Financial Group became a strategic investor in KDAC, expanding its presence in secure digital asset infrastructure.
- NH Bank (NongHyup) announced plans in July 2025 to collaborate with tech firms Hexlant and Korea Information & Communications Co. to launch digital asset services.
- Woori Bank entered a joint venture with Coinplug Inc., a Bitcoin-focused fintech firm, to develop a regulated custody solution.
These moves reflect a broader trend: traditional finance embracing blockchain not through speculative trading, but via secure, compliant infrastructure.
Why Custody Could Be Korea’s Crypto Future
Digital asset custody offers several advantages over unregulated exchange models:
- Lower Risk for Banks: Unlike trading platforms exposed to volatility and fraud, custody is a fee-based, low-risk service focused on security and compliance.
- Regulatory Alignment: Custodians enforce KYC/AML protocols, aligning with government oversight goals.
- Institutional Adoption: Secure custody solutions encourage pension funds, corporations, and asset managers to allocate capital to crypto.
- User Protection: Funds are stored offline (cold storage), reducing exposure to hacks and exchange failures.

Moreover, custodial services inherently support real-name verification—making them a natural fit for Korea’s regulatory framework. They act as a bridge between decentralized assets and centralized oversight.
Frequently Asked Questions (FAQ)
Q: Why are so many Korean crypto exchanges shutting down?
A: Due to new regulations requiring real-name banking partnerships. Only four major exchanges have secured these ties; others lack compliance infrastructure and face closure.
Q: Can Korean banks offer crypto services directly?
A: No—current laws prohibit direct involvement. Banks instead form joint ventures with licensed blockchain firms to provide custody services.
Q: What is digital asset custody?
A: It’s a secure service for storing and managing digital assets like cryptocurrencies, typically used by institutions needing protection against theft and regulatory compliance.
Q: Is personal crypto ownership banned in South Korea?
A: No. Individuals can still hold and trade crypto on registered exchanges with real-name accounts. The crackdown targets unregulated platforms, not retail investors.
Q: How does custody help prevent tax evasion?
A: Custodial providers maintain auditable records of transactions and holdings, making it easier for tax authorities to monitor and enforce reporting.
Q: Will digital asset custody replace crypto exchanges in Korea?
A: Not replace—but complement. Exchanges will focus on trading; custody will handle secure storage, especially for institutional clients.

Conclusion: Regulation as a Catalyst for Innovation
South Korea’s aggressive stance on crypto regulation isn’t stifling innovation—it’s redirecting it. The closure of dozens of unregulated exchanges marks the end of an era defined by speculation and opacity. In its place, a more sustainable model is emerging: one built on security, transparency, and institutional trust.
Digital asset custody represents more than just a business opportunity—it’s a strategic evolution. For Korean banks, it’s a way to participate in the blockchain revolution without overstepping legal boundaries. For regulators, it ensures oversight without suppression. And for investors, it promises safer access to digital wealth.
As global markets watch Seoul’s approach, one thing becomes clear: the future of crypto may not lie in wild price swings—but in the quiet strength of secure, regulated infrastructure.
