The Japanese banks are exploring new horizons in the financial sector through the use of stablecoin. 

The three main banking institutions of Japan—MUFG (Mitsubishi UFJ Financial Group), SMBC (Sumitomo Mitsui Banking Corporation), and Mizuho—have announced their participation in a new platform based on stablecoin to facilitate cross-border transfers. 

This ambitious project, nicknamed “Project Pax”, also involves major companies in the blockchain sector such as Progmat, Datachain, and TOKI. The goal is to create an efficient and secure system for international payments, leveraging stablecoin and blockchain technology.

Stablecoin: their role in Japanese banks

The stablecoin are cryptocurrencies designed to maintain a stable value, usually pegged to a fiat currency like the dollar or the yen. Unlike traditional cryptocurrencies like Bitcoin, stablecoin offer price stability, making them ideal for payments and international transfers. 

Japan, always at the forefront in adopting new technologies, sees in stablecoins an opportunity to transform the way global financial flows are managed.

For Japanese banks like MUFG, SMBC, and Mizuho, the use of stablecoins represents an innovative solution to reduce transaction costs, accelerate payment times, and improve transparency in international operations. 

These banks are ready to explore the advantages that blockchain and stablecoin can offer in the banking sector, especially in a context where cross-border transactions are often complicated by high costs and long timeframes.

What is the “Project Pax”?

The Project Pax is an experimental platform that aims to facilitate international transfers through the use of stablecoins issued by participating banks. The platform will be managed by blockchain companies such as Progmat, a Japanese company specializing in digital infrastructure for the financial sector, Datachain, which provides interoperability solutions between blockchains, and TOKI, a provider of platforms for international payments based on blockchain.

The project, which will initially involve MUFG, SMBC, and Mizuho, aims to expand and include other banks globally. This will allow the creation of an international banking network, where transactions can be executed more efficiently thanks to the use of stablecoins.

The platform Project Pax will use stablecoins as a means of transferring value between participating banks. Each bank will issue its own stablecoin, anchored to its national currency or another reference currency. 

These stablecoin will be used to execute international payments in real-time, eliminating the long clearing and settlement processes typical of traditional banking systems.

Furthermore, the blockchain will ensure that transactions are secure, transparent, and immutable. This aspect is fundamental for banks, which must guarantee regulatory compliance and the security of operations. Datachain and TOKI will provide the interoperability technologies that will allow different blockchains to communicate with each other, ensuring that transactions can be executed smoothly even between different platforms.

Advantages of using stablecoin for international transfers

The use of stablecoin within Project Pax will bring numerous advantages to Japanese banks and their customers. Firstly, transaction costs will be significantly reduced compared to traditional methods, such as the SWIFT system, which involves high fees. 

Stablecoins allow the elimination of various intermediaries and the direct transfer of money between the parties involved.

Secondly, the tempi di pagamento will be drastically reduced. While international bank transfers can take several days, the use of stablecoins will allow for almost instantaneous transactions, with a significant improvement in operational efficiency.

Finally, the aspect of transparency will be strengthened thanks to the use of blockchain. Every transaction will be recorded in a public ledger, which can be consulted by the competent authorities to ensure regulatory compliance and prevent illicit activities such as money laundering.

Although the Project Pax originated in Japan, the ambitions of the project are global. The inclusion of other international banks in the platform is one of the main objectives, with the intention of creating a global infrastructure for cross-border payments based on stablecoin. In this way, banks around the world will be able to leverage the platform to execute international payments more efficiently.

The participation of various banking institutions at a global level will not only increase the adoption of stablecoin, but will also create greater interconnection between the financial systems of different countries, improving liquidity and reducing operational barriers.

Future implications for banks and the financial sector

The Project Pax represents a significant example of how Japanese banks, such as MUFG, SMBC, and Mizuho, are driving innovation in the financial sector. The use of stablecoins could redefine the future of cross-border transfers, creating a faster, cheaper, and more secure system compared to traditional methods.

If the project is successful, it will not only strengthen Japan’s position as a leader in the adoption of blockchain and cryptocurrencies, but it could also influence how banks around the world handle international payments. Stablecoins could become a standard for global transactions, paving the way for an increasingly digital and interconnected financial future.


The initiative Project Pax, led by MUFG, SMBC, and Mizuho, represents an important step forward towards the adoption of stablecoins in the Japanese and international banking sector. Thanks to this platform, cross-border transfers could become more efficient, secure, and transparent, marking a significant change in the global payments landscape.
