Japan’s Financial Services Agency was preparing to examine whether Japanese banks could acquire and hold crypto assets for investment purposes, the Yomiuri Shimbun reported on October 19, 2025. The reported review represented a potential reversal of supervisory treatment that effectively prevented investment holdings, but it did not authorize any bank to buy bitcoin or another crypto asset.

The report also said policymakers would consider whether members of banking groups could enter the registered crypto-exchange business. Both questions were expected to go before the Financial System Council’s working group on the crypto-asset system. No final rule, implementation date, eligible-asset list or exposure limit was announced on October 19.

What the reported change covered

The distinction between a legal prohibition and supervisory policy was important. Japan’s approach did not categorically make every bank acquisition of crypto unlawful. Instead, supervisory guidance required acquisitions and holdings to remain within the minimum necessary scope and excluded holding crypto for investment purposes.

According to the October 19 reporting, the FSA was considering treating crypto more like other investable assets, subject to controls addressing its distinctive risks. That was a balance-sheet question: whether banks could hold crypto for their own investment portfolios. It was separate from whether a bank could sell, broker or recommend crypto to customers.

Allowing a securities or other subsidiary within a banking group to register as a crypto-asset exchange operator would likewise differ from permitting the bank itself to conduct unrestricted crypto dealing. Corporate separation, licensing and prudential controls could determine where losses and operational risks sat within a group.

Why the review mattered

Japan had already built a registration and customer-asset framework for crypto exchanges. Bringing established banking groups further inside that perimeter could expand competition and connect digital-asset services more closely with conventional finance.

The same connection created the central policy problem. Crypto holdings exposed banks to sharp price movements, while exchange activity introduced custody, cybersecurity, money-laundering and reputational risks. A bank’s participation could also cause customers to mistake institutional availability for an assurance that an asset was safe or suitable.

The October 19 development was therefore consequential as a change in regulatory direction, not as evidence of immediate bank demand. The surviving event-day reporting did not identify a bank that had committed capital, quantify prospective purchases or establish that any proposal would become binding.

Evidence and market limits

A second contemporaneous account published late on October 19 repeated that the FSA was considering investment holdings and exchange registration. Bloomberg reported on October 20 that an FSA official confirmed the agency was weighing bank holdings where appropriate risk-management structures existed.

No reviewed source supplied a controlled event study connecting the report to bitcoin, bank shares or broader crypto-market prices. Crypto trades continuously across venues, and the report emerged during a volatile period. This reconstruction therefore makes no return, volume or causal market claim.

Later official confirmation

On October 22, 2025, three days after the report, official FSA materials directly confirmed the policy question. The agency’s working-group presentation described existing guidance as prohibiting investment-purpose holdings and proposed considering permission for bank and insurance-company portfolios, provided adequate risk-management systems were in place.

The October 22 record was more cautious about banks issuing, selling or intermediating crypto for customers. FSA staff argued that investor protections and a sound trading environment should be developed before those activities were reconsidered. The working group discussed the proposal; it did not convert it into a final authorization. That later primary record corroborates the October 19 report without changing the proposal’s event-day status.
