South Korea's first Bitcoin-backed bank loan: Jeonbuk Bank accepts BTC as collateral

South Korea's first Bitcoin-backed bank loan: Jeonbuk Bank accepts BTC as collateral

Jeonbuk Bank, part of JB Financial Group, launched South Korea's first won-denominated loans backed by Bitcoin on October 12. By October 18, the news had spread widely across industry media.

For the Korean market, this is a notable step. For the first time, Bitcoin has become collateral at a regular bank, not just an asset on an exchange.

Who can get a Bitcoin-backed loan

The product is aimed only at companies. The money is issued for working capital, and loans are not yet available to individuals.

Only Bitcoin can serve as collateral. The bank does not accept other digital assets at launch.

Who holds the collateral and what happens in a default

The bank does not hold the coins itself. The collateral is kept by a specialized custodian from among providers registered under Korea's financial information disclosure law.

In a default, the bank does not take ownership of the Bitcoin. The coins are sold through court auctions under the updated civil enforcement rules in force since October 1.

In our view, this setup removes the regulator's main fear. The bank gets collateral but does not become a holder of cryptocurrency on its balance sheet.

How the bank values Bitcoin

Jeonbuk Bank built its own system to value the collateral. It takes prices from several global exchanges and accounts for volatility metrics.

For an arbitrage trader, this is the most interesting detail. The price of Bitcoin differs across venues, and in Korea the gap with the global market has historically been more noticeable than anywhere else.

Where the kimchi premium comes in

The kimchi premium is the markup at which crypto trades in won on Korean exchanges relative to global venues. It grows, shrinks and sometimes turns negative.

We believe that valuing collateral across several global exchanges makes it less dependent on local distortions. If the bank looked only at the Korean market, the value of the collateral would jump along with the premium.

From what we see, cross-exchange spreads are most visible precisely at such moments, when the local and global markets diverge. Bank demand for Bitcoin as collateral may eventually add one more source of such gaps.

What comes next

The bank allows that its client base may expand and that other digital assets may be added alongside Bitcoin. It will all depend on demand and regulation.

The bank has not named the timing or parameters of such an expansion. For now, it is a product for companies and for Bitcoin only.
