A regional South Korean lender has just done something none of the country’s banks had done before. Jeonbuk Bank now lets corporate clients borrow Korean won using Bitcoin as collateral.
The product launched on October 12, 2026, and is described as the first won-denominated loan in South Korea secured by Bitcoin.
Jeonbuk Bank, a subsidiary of JB Financial Group, says it plans to expand the offering depending on market demand and how regulations develop. For now, the door is open only to businesses.
How the loans actually work
Jeonbuk Bank does not take custody of the Bitcoin pledged against these loans. Instead, it works with qualified virtual asset service providers that meet South Korea’s custody standards.
Those custodians must comply with local rules, including ISMS certification and the Virtual Asset User Protection Act. ISMS is South Korea’s information security management certification, essentially a government-backed stamp saying a firm’s data and systems meet a defined security bar.
The bank’s role is narrower. It handles valuation and lending, and it does not own or manage the Bitcoin sitting in custody.

The loans are restricted to corporate clients. The money is meant for business operating funds, which covers payroll, suppliers, and keeping the lights on.
Only Bitcoin qualifies as collateral. The bank chose Bitcoin because of its superior liquidity and higher trading volume compared with other digital assets.
Pricing a volatile asset without losing sleep
Jeonbuk Bank’s answer is a layered valuation process. It prices the collateral using weighted average prices drawn from multiple global exchanges rather than relying on a single venue.
The model also factors in volatility medians and runs stress tests.
Recovery in a default runs through court-ordered auctions under revised Civil Execution Rules, which took effect on October 1, 2026. The Bitcoin does not simply transfer to the bank when a borrower misses payments.
The timing is hard to ignore. The rule change landed less than two weeks before the product launched, giving the bank a legal path to recover value from seized digital assets.
A bank that wants to be a crypto bank
The bank’s president has expressed a desire for Jeonbuk Bank to evolve into a “crypto bank.”
The product has been framed as paralleling offerings from global institutions such as JPMorgan Chase.
By outsourcing custody to licensed providers and routing defaults through the courts, the bank keeps a clear line between lending money and holding crypto directly.
What this means for Korean banking and crypto
The most immediate impact falls on Korean companies that already hold Bitcoin. Until now, getting cash out of those holdings usually meant selling them.
Jeonbuk Bank has indicated it might eventually open the product to a wider range of clients and potentially accept other digital assets, depending on demand and the regulatory framework.
