South Korea to Enforce Bank-Grade Liability on Crypto Exchanges After Upbit Hack, Report Finds

In a landmark shift for digital asset regulation, South Korea is considering bank-level, no-fault liability rules for crypto exchanges. The push aims to close gaps in consumer protection exposed by the Upbit hack and rising concerns about system reliability across the country’s crypto ecosystem. If enacted, the changes would place exchanges on par with traditional financial institutions under the Electronic Financial Transactions Act, shifting some risk from users to platforms and potentially reshaping the economics of operating in Korea’s crypto market.

What “bank-level liability” would mean for crypto exchanges

No-fault compensation explained

Under a no-fault compensation framework, customers would be compensated for losses arising from hacks or significant system failures regardless of fault, much like deposit protection in banks. In practical terms, users could recover funds even if an exchange is determined not to be negligent, creating a stronger safety net that buttresses consumer confidence in digital assets.

Comparison with banks and electronic payment firms

Today, South Korea applies no-fault protection to banks and certain electronic payment firms under the Electronic Financial Transactions Act. Crypto exchanges operate outside that shield. The proposed shift would elevate exchanges to the same standard of care, with consequences for how they manage risk, maintain reserves, and communicate with customers during incidents.

Implications for exchanges and customers

For exchanges, the regulatory tilt could mean higher compliance costs, stricter cyber hygiene requirements, and more robust incident response plans. For customers, it promises quicker redress after breaches and outages, potentially reducing the financial sting of cybercrime. Yet higher costs for platforms could influence fee structures, trading spreads, and product innovation in a market already navigating volatility and regulatory scrutiny.

The Upbit incident: timeline, impact, and what it signaled

Timeline of the hack

On November 27, a breach at Upbit, operated by Dunamu, led to the transfer of more than 104 billion Solana-based tokens to external wallets within a single hour. The scale of the event drew intense scrutiny from lawmakers, regulators, and market participants who wondered how such a large exfiltration could unfold so swiftly.

Financial impact

The tokens involved were valued at roughly 44.5 billion won, about $30.1 million at the time. While not the largest crypto theft on record, the incident highlighted vulnerabilities in security architecture and monitoring across major exchanges in Korea.

Response and transparency concerns

Critically, authorities noted that Upbit detected the breach around 5 a.m., but did not alert the Financial Supervisory Service (FSS) until nearly 11 a.m. That reporting delay sparked questions about governance, incident disclosure timelines, and possible political theater surrounding a broader consolidation in the fintech sector following Dunamu’s merger with Naver Financial.

Legislative revisions under consideration

The Financial Services Commission (FSC) is examining rules that would impose bank-level oversight on crypto exchanges, aligning them with the standards that govern banks and paperless payment providers. A core element is ensuring that losses from cybersecurity incidents and service disruptions are covered for customers, even when the platform is technically not at fault.

IT security standards and penalties

Proposed revisions would mandate stronger IT security controls, including routine security audits, resilience testing, and more robust incident response protocols. Lawmakers are contemplating penalties that would deter lax practices, with fines potentially scaling up to 3% of annual revenue for breaches, matching the penalties banks face for serious violations.

Fines and enforcement

Currently, crypto exchanges face a maximum fine of about $3.4 million. The new framework would intensify enforcement, creating a direct link between market integrity and corporate governance in Korea’s crypto sector.

Timeline to debate

Officials are aiming to bring the related draft stablecoin bill to the National Assembly by December 10, with discussions anticipated during the extraordinary session in January 2026. If lawmakers miss the deadline, regulators have signaled they may proceed without a government-aligned timetable.

System reliability and outages: a pattern regulators are trying to break

Data from the FSS on outages

Data submitted to lawmakers show a pattern of outages across the five largest exchanges—Upbit, Bithumb, Coinone, Korbit, and Gopax—amounting to 20 system failures since 2023. These incidents affected well over 900 users and led to more than 5 billion won in combined losses, underscoring the fragility of some critical digital asset platforms in the region.

Upbit’s six outages and their impact

Upbit alone reported six failures affecting approximately 600 customers. While not all outages result in losses, each disruption erodes trust and underscores the need for resilient infrastructure, continuous monitoring, and transparent disclosure practices that communities can rely on during turbulent times.

Costs to exchanges and potential pass-through

More stringent security standards and bank-level oversight will raise operating costs for crypto exchanges. Exchanges may respond with higher withdrawal or trading fees, tighter liquidity requirements, or reduced product flexibility in the short term as they adapt to the new risk framework.

Protection, trust, and market growth

From a consumer protection perspective, the shift aims to restore trust in Korea’s crypto markets. Investors often weigh security, recourse options, and regulatory clarity when deciding whether to participate in digital asset ecosystems. A credible no-fault regime could attract institutional players seeking safer on-ramps for crypto investments while pressuring platforms to demonstrate stronger governance.

Impact on investors and the broader market

In the medium term, clearer liability rules may influence the risk appetite of traders and funds, potentially stabilizing price swings tied to security incidents. Conversely, if penalties or compliance costs compress margins, liquidity on some exchanges could waver, especially for smaller platforms competing with larger incumbents.

United States and Canada

In North America, liability for exchange outages and hacks varies by jurisdiction and contractual terms. Regulators emphasize customer protections, response timelines, and transparent disclosures, with ongoing discussions about enhancing disclosures and capital requirements for custodial wallets and trading venues.

European Union and the UK

The EU has moved to harmonize crypto rules through MiCA (Markets in Crypto-Assets) and related consumer protection standards, elevating the duty of care for issuers and platforms. The UK, while still refining post-Brexit frameworks, maintains robust monitoring of crypto firms under its financial conduct authority and emphasizes cyber resilience and consumer protections.

Comparative takeaway for Korea

South Korea’s proposed model aligns with a global trend toward stronger accountability for digital asset platforms, especially where customer funds and data are involved. The emphasis on bank-level standards signals a maturing market that prioritizes risk management and consumer confidence as essential rails for sustainable growth.

Pros

Stronger consumer protections that reduce the financial fallout from hacks and outages.
Incentives for exchanges to bolster IT security, risk controls, and incident response capabilities.
Improved trust from retail and institutional investors, potentially widening the market base.

Cons

Increased compliance costs that could raise barriers to entry and slow innovation.
Potential shifts in pricing, liquidity, and trading options as platforms adapt to higher risk management standards.
Challenges for smaller exchanges that may struggle to meet stringent IT and governance requirements.

Implementation challenges

Balancing enforcement with competitive dynamics will be critical. Regulators must define clear standards for incident notification, reserve and insurance requirements, and how no-fault compensation would be funded in practice. Industry groups will likely press for phased implementation, pilot programs, and measurable milestones to ensure smooth transitions.

What investors should watch

Follow updates from the FSC and FSS regarding new rules, timelines, and proposed penalties. Monitor which exchanges publish detailed incident reports and disclose security measures publicly. Diversify holdings and consider using regulated custodians when available.

What exchanges should prioritize

Investors expect transparent disclosure, real-time risk monitoring, and robust backups. Exchanges should invest in encryption, incident response drills, third-party audits, and clear customer-funding protection schemes to meet evolving expectations and regulatory demands.

What consumers can do now

Keep track of exchange security histories, enable multi-factor authentication, diversify across platforms cautiously, and stay informed about consumer protections in your jurisdiction. In markets with evolving rules, informed users act as a check against complacency and poor risk management.

The push toward bank-level liability for crypto exchanges in South Korea reflects a broader realignment between innovation and protection. As Upbit’s incident underscored vulnerabilities, policymakers are signaling that consumer safety must come first, even if it means higher compliance costs and tighter controls for platforms. The coming months will reveal how aggressively the FSC, FSS, and lawmakers push these reforms and how the industry adapts. For participants in Korea’s crypto economy, the era of uncertain governance may give way to a clearer, more accountable framework that supports sustainable growth while defending users against losses from hacks and system failures.

What does “bank-level liability” mean for crypto exchanges?

It means exchanges would be held to the same no-fault, customer-protection standards that banks currently face, including compensating users for certain losses from hacks or outages, even when the exchange isn’t at fault.

How would compensation work if there is no fault?

In a no-fault regime, customers could be eligible for compensation from the exchange or a required protection mechanism, such as a compensation fund or mandatory insurance, regardless of negligence findings.

When will the new rules come into effect?

Official timelines are still being debated. Lawmakers expect to discuss the draft regulations in the National Assembly, with a view toward a formal vote during the January 2026 extraordinary session. A separate stablecoin bill is also in motion with a December deadline for a draft, potentially signaling parallel pace for related reforms.

Which entities would be affected?

Primarily cryptocurrency exchanges operating in Korea, including the top-tier platforms like Upbit, Bithumb, Coinone, Korbit, and Gopax, along with their custodial and risk-management partners. Providers of electronic payment services and banks already subject to similar protections could see alignment in broader financial regulation efforts.

How does this affect Upbit and the Dunamu-Naver Financial relationship?

The Upbit incident has intensified scrutiny of reporting timelines and governance. A faster, more transparent response regime would be expected regardless of corporate structure, and policymakers may seek to ensure that mergers or acquisitions do not dilute protection standards or delay critical disclosures.

What should users do to protect themselves?

Staying informed about regulatory changes, using reputable exchanges with strong security practices, enabling protective measures like MFA, and diversifying assets across safe storage options can mitigate risk as the regulatory landscape evolves.

Is stablecoin regulation part of this package?

Not directly in the same clause, but lawmakers have highlighted a broader push on crypto regulation, including a stablecoin bill due for debate. The two tracks are interlinked in terms of overall market integrity and consumer protection in Korea’s digital asset ecosystem.
