Japan is witnessing a significant shift in its financial landscape as the Financial Services Agency (FSA) initiates discussions on regulatory reforms that would allow domestic banks to acquire and hold non-backed crypto assets, including Bitcoin, for investment purposes. This move signifies a marked departure from previous restrictions and reflects the maturation of the domestic crypto market.
Historically, Japan’s supervisory guidelines, revised in 2020, effectively prohibited banking groups from acquiring crypto assets, citing concerns over their extreme volatility. However, recent data indicates a thriving ecosystem, with the number of crypto accounts surpassing 12 million by the end of February this year—a 3.5-fold increase over the past five years. By recognizing digital assets as a legitimate asset class, this new regulatory consideration could lead to diversification in bank portfolios and enhance profitability.
As part of its approach, the FSA is prioritizing risk management alongside the promotion of institutional crypto investment. Key discussions at the Financial System Council will focus on implementing measures to safeguard financial stability, including the introduction of strict capital requirements and exposure limits that would regulate the volume of crypto assets banks can hold relative to their capital base. This balanced approach is designed to foster innovation while ensuring financial soundness, aligning with global regulatory trends that embrace controlled experimentation.
In parallel, Japan’s three largest banking groups—Mitsubishi UFJ Financial Group (MUFG), Sumitomo Mitsui Financial Group (SMFG), and Mizuho Financial Group—are collaborating on issuing yen-pegged stablecoins. The plan also includes the potential expansion to a US dollar-pegged version. This initiative is made possible by the updated Payment Services Act 2023, which presents a clear legal framework for stablecoin circulation.
The banks intend to utilize a system developed by fintech firm Progmat Inc., which will establish a unified standard for these stablecoins. This standardization is aimed at ensuring interoperability and seamless transactions among corporate clients of the three banks. The initial target for adoption includes facilitating corporate settlements for Mitsubishi Corp., with the goal of real-world application within the current fiscal year. The overarching aim is to harness blockchain technology to streamline and enhance the efficiency of corporate payments and cross-border remittances, thereby alleviating administrative burdens for Japanese corporations.
In further support of this digital asset integration, the FSA is contemplating the possibility of allowing banking groups to register as Crypto Asset Exchange Service Providers. This move would bolster the role of compliant traditional finance institutions within the expanding digital asset ecosystem, solidifying their influence and operational capacity in this burgeoning financial sector.
