Japan’s Banking Regulators Turn Toward Crypto
Japan’s Financial Services Agency (FSA) is reportedly reviewing rules that could let banks hold cryptocurrencies such as Bitcoin for investment and operations. The move would be a dramatic shift from the country’s cautious stance on digital assets.
From Restriction to Reform
Until now, Japanese banks have been barred from holding crypto due to volatility and risk management concerns. The upcoming proposal, set for discussion at a Financial Services Council meeting, could align digital asset rules with those for traditional investments like stocks and bonds.
Crypto Rules Under the Microscope
If approved, the FSA would likely create strict capital and risk controls before allowing banks to hold crypto. Regulators are also expected to design safety frameworks to manage sudden price swings that could affect a bank’s balance sheet.
Banks Could Also Become Crypto Exchanges
In a bigger twist, the FSA is considering letting bank groups register as licensed crypto exchange operators. This means Japanese banks could soon offer direct trading and custody services.
Crypto Adoption Surges in Japan
Japan’s crypto market is booming — over 12 million accounts were registered by early 2025, a 3.5x increase from five years ago. The FSA also plans to shift crypto oversight from the Payment Services Act to the Financial Instruments and Exchange Act (FIEA), treating digital assets more like securities.
Big Banks Go Digital
Japan’s banking giants — MUFG, SMBC, and Mizuho — are already testing a yen-pegged stablecoin for cheaper and faster corporate payments. Meanwhile, regulators are preparing stricter rules against crypto insider trading.
