Although Japan has long restricted banks from holding cryptocurrencies, the Financial Services Agency is now considering rules that would permit banks to invest directly in Bitcoin and other crypto assets, signaling a potential integration of digital tokens into the traditional banking sector. The proposal reflects a shift in regulatory posture prompted by a rapidly expanding domestic market, which counted over 12 million crypto accounts as of February 2025, and by international developments that have seen other jurisdictions reconsider the role of banks in crypto markets. The FSA envisions a framework that treats certain crypto assets with parity to traditional securities, aiming to bring established investor protections and disclosure requirements to digital-asset investments.
Japan’s FSA is weighing rules to let banks directly hold Bitcoin and crypto, aligning some tokens with securities.
The FSA’s plan emphasizes the creation of a robust risk management framework, which would require banks to assess market, liquidity, and operational risks associated with crypto holdings, and to maintain capital buffers appropriate to those risks. Enhanced liquidity risk management will be critical to ensure banks can operate smoothly during periods of market stress. Regulatory alignment with the Financial Instruments and Exchange Act is under consideration, a move intended to subject crypto service providers and bank-held tokens to familiar statutory obligations, reporting standards, and oversight mechanisms. Such alignment seeks to reduce regulatory fragmentation and to provide clearer legal certainty for banks, institutional investors, and retail customers.
Discussions within the Financial Services Council, which advises the Prime Minister on financial policy, will examine how to integrate crypto assets into traditional banking while protecting financial stability, and the council’s recommendations may influence the detailed calibration of prudential rules. Practical measures under review include criteria for which tokens qualify as investable assets, capital and liquidity requirements for bank portfolios, and the conditions under which banks could register as licensed cryptocurrency exchange operators to expand market access. Policymakers are also weighing supervisory resources needed to monitor exchanges, custody arrangements, and counterparty exposures.
Cautionary considerations underpin these reforms, as regulators remain concerned about extreme price volatility, market manipulation, and technology-driven operational risks, and they intend to impose strict oversight to mitigate contagion risks affecting banks’ balance sheets. If adopted, the proposed changes could catalyze fintech innovation in digital banking across Asia, while setting precedents for how traditional financial institutions engage with crypto markets in a regulated environment. The FSA has also been discussing the possibility of allowing bank groups to register as crypto exchange operators to broaden retail access. The move is likely to attract institutional investment into Japan’s fintech sector, further boosting development and capital flows.
