Japan’s financial landscape is transforming digitally. The Financial Services Agency (FSA) has begun considering regulatory reforms permitting domestic banks to acquire and hold non-backed crypto assets, such as Bitcoin, for investment.

In addition, the nation’s three largest banking groups are pursuing a plan to issue yen-pegged stablecoins jointly. This dual push by regulators and traditional finance (TradFi) giants aims to rapidly integrate digital assets into the mainstream economy.

FSA Pushes to Integrate Bitcoin into Banking Balance Sheets

The FSA’s deliberation signals a significant re-evaluation of its conservative regulatory stance. Historically, supervisory guidelines revised in 2020 effectively barred bank groups from acquiring crypto assets for investment, citing extreme volatility concerns.

The domestic crypto market, however, is showing robust maturity. Data indicates that the number of crypto accounts opened in Japan surpassed 12 million by the end of February this year, representing a 3.5-fold increase over the past five years.

Allowing banks to allocate capital to digital assets would treat them as a recognized asset class. This would diversify bank portfolios and potentially enhance profitability.

Regulating Risk: Capital Requirements and Exposure Limits

Despite supporting institutional crypto investment, the agency remains focused on establishing robust safeguards. Key discussions at the Financial System Council will center on implementing measures to ensure financial soundness. Specifically, these measures will mandate strict requirements for banks.

Crucially, the working group will debate the imposition of exposure limits. These limits will restrict the volume of crypto assets banks can hold relative to their capital base.

Ultimately, this measured, two-pronged approach—allowing entry while strictly managing risk—aligns with the global regulatory philosophy of fostering innovation in a controlled environment.

Convergence: Institutional Infrastructure and Global Impact

The collaborative stablecoin effort is adding momentum to Japan’s digital asset integration. The nation’s three megabanks—Mitsubishi UFJ Financial Group (MUFG)Sumitomo Mitsui Financial Group (SMFG), and Mizuho Financial Group—are moving to issue corporate-use stablecoins jointly.

The focus is initially on a yen-pegged version, with plans to expand to a US dollar-pegged coin later. This initiative leverages the updated Payment Services Act 2023, establishing a clear legal framework for stablecoin circulation.

The banks plan to use the system developed by fintech firm Progmat Inc. The key innovation is the establishment of a unified standard for these stablecoins. This ensures interoperability and seamless fund transfers among the corporate clients of all three banks. They are targeting initial adoption for corporate settlements by a major trading house, Mitsubishi Corp., with expected real-world application within the current fiscal year.

The primary objective is to use blockchain technology for faster, cheaper, and more efficient corporate payments and cross-border remittances, which will help reduce Japanese corporations’ administrative burdens.

Moreover, the FSA is further supporting infrastructure build-out by considering allowing bank groups to register as Crypto Asset Exchange Service Providers. This solidifies the role of highly-compliant TradFi institutions in the entire digital asset ecosystem.
