South Korea’s central bank is calling on lawmakers to require crypto exchanges to install built-in emergency trading halts, and one of the most expensive operational errors in crypto history is the reason why.
What the Bank of Korea Is Proposing
The Bank of Korea published a payments report on Monday calling for crypto exchanges to adopt mechanisms similar to the Korea Exchange’s trading curbs, circuit breakers that automatically suspend trading when prices suddenly spike or crash. The central bank hinted that the virtual asset industry currently lacks internal control mechanisms and faces lower regulatory intensity compared to established financial institutions.
Beyond trading halts, the BOK also wants exchanges to have automated systems that detect and block erroneous transactions caused by human error, and tools that continuously verify whether a platform’s internal ledger matches its actual on-chain assets.
The $40 Billion Blunder Behind the Push
On February 6, 2026, South Korean exchange Bithumb accidentally credited roughly 620,000 Bitcoin to hundreds of users during a promotional campaign. The intended payout was 620,000 Korean won, worth about $450. Instead, a staff member entered the reward unit as Bitcoin rather than won, briefly pushing the total value of the error above $40 billion.

Users who suddenly saw massive balances in their accounts rushed to sell. Bitcoin’s price on Bithumb plunged as much as 17%, briefly trading near $55,000 while prices on other exchanges remained stable. Bitcoin-backed loans were forcibly liquidated, and ordinary users who panic-sold suffered real losses. Bithumb froze affected accounts within 35 minutes and recovered 99.7% of the misallocated Bitcoin. However, 1,788 BTC worth roughly $125 million had already been sold before the exchange could act, a shortfall the company covered from its own reserves.
The Bank of Korea’s report revealed that Bithumb had allowed staff to distribute Bitcoin without supervisor approval or verification by internal monitoring departments, and that the exchange’s fraud detection system failed to trigger during the incident. Bithumb’s CEO later admitted the erroneous payout amounted to 15 times the exchange’s actual Bitcoin holdings at the time.
Regulators Have Been Moving Fast Since February
The circuit breaker proposal is the latest layer in a broader crackdown. The Financial Services Commission (FSC) has already ordered all domestic exchanges to implement automated five-minute reconciliation between internal ledgers and actual wallet balances by end of May, after finding that three of South Korea’s five major exchanges were still running 24-hour balance checks.
The FSS launched on-site inspections across all exchanges, deployed AI tools to flag suspicious trading in real time, and indicated Bithumb may face sanctions under the Virtual Asset User Protection Act. Bithumb has since been hit with a six-month partial suspension of operations.
On X (formerly Twitter), South Korea’s Financial Services Commission confirmed it ordered inspections of internal control frameworks industry-wide, framing the Bithumb incident as a systemic failure, not an isolated one.
Crypto analysts on X flagged a wider concern: Upbit and Bithumb together handle roughly 96% of South Korea’s crypto trading volume, meaning operational failures at either exchange move markets well beyond Korean borders.
The Bigger Shift: TradFi Standards Are Coming to Crypto
South Korea has about 11 million crypto users holding an estimated $48 billion in digital assets. The Bithumb incident has accelerated a regulatory reset that was already building. South Korea’s comprehensive Digital Asset Basic Act remains stalled due to a dispute between the FSC and the Bank of Korea over stablecoin oversight, but the circuit breaker push signals the central bank is advancing its own agenda.
The country has also lifted an eight-year ban on corporate and institutional crypto investment, with roughly 3,500 firms now permitted to trade. What South Korean regulators are assembling, circuit breakers, real-time reconciliation, kill switches, executive accountability, monthly audits, is effectively a bank-grade risk framework for crypto exchanges. It may well become a blueprint other markets follow.
