What If Bitcoin Falls? Jeonbuk Bank Bitcoin-Backed Loans

Seoul, South Korea — October 12, 2026 — Jeonbuk Bank has begun lending Korean won to corporate borrowers against Bitcoin collateral, but it has not publicly set out the price levels that would trigger a collateral call or sale, according to reports published Monday.

What happens to the loan when Bitcoin falls?

A lower BTC price reduces the value of the collateral while the amount owed does not fall with it. That pushes up the loan-to-value ratio, or LTV: the outstanding loan divided by the current collateral value. Interest and fees can also increase the balance due.

For illustration only, a company borrowing 50 million won against Bitcoin worth 100 million won starts at a 50% LTV. If BTC falls 30%, the collateral is worth 70 million won and the LTV rises to about 71.4%, before interest or fees. These figures are not Jeonbuk Bank’s loan terms.

The bank has not disclosed its opening LTV, any price or LTV trigger, a deadline to add collateral, or a mandatory sale threshold. IT Chosun reported that a bank spokesperson said the collateral-monitoring and recovery arrangements would be developed further as the rules change. On the information made public so far, a BTC price drop alone cannot be said to trigger an automatic sale.

What Jeonbuk Bank has disclosed

Edaily reported that the product is for companies seeking operating funds and accepts Bitcoin only. A specialist custodian holds the pledged BTC; Jeonbuk Bank is reported not to own or directly manage the coins. The bank says it uses a reference price based on weighted prices from multiple global exchanges and volatility indicators, and says it has stress-tested sharp falls. The bank has not released the test scenarios or results.

• The loans are for corporate borrowers and business operations, not a disclosed retail product.
• Bitcoin is the only collateral described in the reports.
• The first borrower’s identity and loan amount have not been disclosed.

Default is different from a price dip

Reports describe a recovery route in which the bank would enforce its security rights and seek sale proceeds through court procedures if a default or other enforcement event occurs. That is not the same as a published rule to sell BTC whenever its market price crosses a particular level. The public reports do not disclose the contract’s cure period, sale timetable, or how any shortfall would be treated if sale proceeds do not cover the debt.

IT Chosun reported that the bank has made an actual loan, while the borrower’s identity remains private. The outlet also quoted the bank as saying it would refine monitoring and recovery systems. Until the bank publishes more detail, borrowers and lenders cannot calculate from the public information exactly when a falling BTC price would require action.

Frequently Asked Questions

What happens to a Bitcoin-backed loan if BTC falls?

The collateral loses value while the loan balance remains, so the loan-to-value ratio rises.

Will Jeonbuk Bank automatically sell the Bitcoin after a price drop?

The reports do not disclose an automatic-sale rule or price trigger. They describe a court-based recovery process if a default or other enforcement event occurs.

What loan-to-value ratio or margin-call threshold does the bank use?

That information has not been made public in the reports reviewed. The opening loan-to-value ratio, collateral-call threshold, and time to add collateral are undisclosed.

Who can apply for the loan?

Reports describe loans for companies’ business operating funds, with Bitcoin as the eligible collateral. They do not describe a retail product.

Who holds the pledged Bitcoin?

A specialist custodian holds it, according to the reports. Jeonbuk Bank is reported not to own or directly manage the coins.

What if selling the collateral does not cover the debt?

The reports do not explain how a shortfall would be treated. The available public information does not establish whether it would be forgiven or remain payable.
