South Korea’s central bank is weighing whether to bring ‘circuit breaker’ style safeguards from traditional markets into the world of crypto, as regulators grapple with how to contain risks in fast-moving digital asset trading.
The discussion is informed in part by how traditional markets manage volatility. In the U.S., the stock market relies on circuit breakers to curb panic selling and stabilize trading when sharp declines threaten to spiral. These protections are designed to halt trading once predefined thresholds are breached, giving markets time to cool and preventing disorderly sell-offs.
These circuit breakers are triggered when specific thresholds are met, and the Bank of Korea may consider similar guardrails for South Korea’s digital assets market following a disastrous incident at crypto exchange Bithumb.
In February, the exchange ran a promotion offering a small cash reward. However, a Bithumb employee selected the wrong denomination and mistakenly transferred 620,000 bitcoin (valued at roughly $43 billion at the time) instead of South Korean won. The error caused bitcoin prices on Bithumb to plummet 17%, triggering widespread losses for some users.
In a recent report, the Bank of Korea argued that this incident highlights the urgent need for guardrails in crypto markets that mirror those in traditional financial systems. This could include requiring exchanges to implement stronger early-detection mechanisms, as well as circuit breakers capable of blocking anomalies and pausing trading during periods of high volatility.
Clawing Back Funds
While Bithumb identified the error within about 20 minutes, the central bank noted that the exchange failed to prevent the mistakenly distributed bitcoin from being traded or withdrawn, exacerbating user losses.
Although Bithumb was able to claw back the lion’s share of the bitcoin, it’s still working through the courts to freeze seven bitcoin that remain unrecovered.
Tech Outpaces Regulations
The rapid pace of technological innovation has consistently outstripped regulatory frameworks. For example, the open banking zeitgeist has been fueled by partnerships between fintechs and banks. Yet the collapse of Synapse—which left $265 million in consumer funds in limbo—intensified calls for tighter oversight of such arrangements.
Another challenge is that payments are far faster. Like crypto markets, real-time payment rails eliminate the settlement buffers that institutions have historically relied on to detect fraud or operational errors. As a result, some financial institutions are now exploring ways to reintroduce friction into these processes as a form of risk control.
As seen in South Korea, these vulnerabilities are likely to prompt regulators worldwide to consider implementing stronger safeguards for increasingly powerful, and instantaneous, financial systems.
