Japan built a bank-led stablecoin market. No other country has.

Japan is the first country where banks, not fintechs, define the shape of the stablecoin market. The real market is two regulated, banking-adjacent issuers, JPYC and GYEN; SBI's much larger JPYSC is issued but not circulating, a premint that shows banks took the regulatory lane ahead of demand.

The numbers

The real-market legs are the two tokens with a live holder base. On-chain supply as of 2026-08-13, DB-confirmed:

SBI's JPYSC carries the largest issuance at 20.6 billion yen (20,602,864,448), but it is issued, not circulating. DB verification shows 8 holders, a 94.65% top holder and 114 lifetime transfers, a premint shape. The 8-holder JPYSC against an 11,428-holder GYEN is the issuance-versus-adoption spine: banks took the regulatory lane ahead of a live market.

Why it matters

The three issuers have different owners and one common feature: all are banking-adjacent. SBI is a financial group, its stablecoin issued through SBI Shinsei Trust Bank. JPYC is backed by Fujitsu and Access. GMO-Z.com Trust Company holds a trust licence. That inverts the global pattern, where exchanges and specialist issuers lead and banks lag. The trigger was the revised Payment Services Act, effective June 2023, which created a bank-trust wrapper for electronic payment instruments. Before it, Japanese stablecoins had no regulated lane and none scaled. After it, the banking-adjacent players moved in. The real-market sizes are still small, roughly $14 million across JPYC and GYEN, and even SBI's 20.6 billion yen issuance is a fraction of USDT. The structure is the finding: a regulatory framework handed stablecoin issuance to the banking sector ahead of demand, and it is the reference case for other regulators who want the same outcome.
