What will change when smartphone payments such as PayPay are connected to the Zengin system?[Deep digging]

Funds transfer companies such as PayPay will be able to participate in the “Zengin System,” which was previously restricted to financial institutions such as banks.

This is something that has been discussed among the people concerned for the past few years, and there is no new information at this time. Opening up the Zengin system is the default route.

What will change in daily life and what will be convenient if this becomes a reality?

In the first place, what does it mean to be “connected to the Zengin system”?

The Zengin System has supported operations such as inter-account remittances at banks and credit unions (the photo is an image).

The Zengin Data Communication System (Zengin System) operated by the Zengin Net is an infrastructure in which almost all financial institutions in Japan participate and connect with each other through a network.

Banks can transfer money to other banks, and banks to credit unions because the Zengin System is in operation.

In 2018, the “More Time System” started operating, making it possible to send and receive money transfers 24 hours a day, 365 days a year.

The Zengin System is a so-called domestic exchange transaction*1It is an infrastructure targeted at financial institutions that conductUntil now, operators of cashless services such as PayPay = fund transfer operators*2was unable to participate.

*1 What is domestic exchange trading?…a domestic transaction involving the transfer of funds between individuals or businesses without the exchange of cash. For example, if bank A instructs bank B to transfer 1 million yen, bank A’s account will be negative and bank B’s account will be positive without transporting cash.

*2 Funds Transfer Service Provider……Business operators other than banks that conduct exchange transactions must be registered with the country based on the Fund Settlement Act. There are three types: Type 1 with no remittance limit, Type 2 with a remittance amount of 1 million yen or less, and Type 3 with a remittance amount of 50,000 yen or less, but currently only Type 2 is registered. Businesses such as payment services such as PayPay, d payment, au PAY, Merpay, and overseas remittance services are registered.

However, with the expansion of payment methods by fund transfer service providers and the progress of cashless payments, discussions began on whether to allow fund transfer service providers to connect to the Zengin System. ” and set up the same working group to discuss with related parties.

The Zengin system itself is an expensive system. It forms the core of Japan’s foreign exchange trading, and if this system fails, it will have such an impact that all Japanese foreign exchange trading will stop.

The Zengin System has multiple payment computers installed in Tokyo and Osaka in a redundant configuration, and the cost of stable infrastructure operation is high.

It goes without saying that Mizuho Bank and KDDI are the examples of society’s scrutiny of infrastructure failures, and a certain amount of cost will be necessary.

“Burden” and “Benefits” of Connecting Operators

The cost of maintaining the system is borne by each participating financial institution. In addition, there are fees for individual transactions, and for example, the system cost for FY2021 is estimated to be about 9.2 yen per foreign exchange transaction.

In addition, the operating costs of the domestic exchange system for transactions between banks*3is 62 yen per item. Fees and other charges are incurred in transactions with each financial institution.

These costs don’t simply add up for each transaction, but the more you do, the more it costs.

*3 Domestic exchange system operating expenses……Until then, the interbank fees, which had been set individually between banks, were abolished, and from October 2021, they became the domestic exchange system operating expenses as a unified expense. The fee, which was generally more than 100 yen, has been reduced.

Nonetheless, in response to requests from the government and reports from the Japan Fair Trade Commission, the newly established domestic exchange system operating costs have reduced interbank transaction fees and reduced costs for fund transfer service providers. (However, depending on the fund transfer service provider, a different network service may be used to connect with the bank, and the timing of the cost fluctuation may differ depending on the contract).

This cost burden is also necessary when depositing from a bank to a payment service such as PayPay. By reducing this, the burden on business operators should gradually decrease.

Bank of Japan

In order to connect to the Zengin System, it is necessary to have a current account at the Bank of Japan.

For these reasons,Considering the balance between the burden and benefits that will be incurred, it is difficult to imagine that simply connecting a fund transfer service provider to the Zengin System will have a significant effect.

In the first place, in order to connect to the Zengin System, it is necessary to pay a joining fee and share expenses, and it is necessary to have a current account at the Bank of Japan (the Bank of Japan will conduct an examination).

Since the Financial Services Agency and others will be required to continuously monitor and ensure safety, it will be a heavy burden for emerging companies, many of which are fund transfer service providers.

That said, the Zengin System also has a mechanism for indirect connections. Shinkin already does this. Shinkin Central Bank is directly connected to Zengin System, and individual Shinkin Banks are connected to Shinkin Central Bank. In this method, the Shinkin Central Bank acts as an agent for remittance instructions and connects to the Zengin system.

For example, with PayPay, there is PayPay Bank that is directly connected to the Zengin System, so instead of PayPay itself connecting to the Zengin System, it is possible to connect via PayPay Bank.

Although the cost burden is lighter than direct connection, it is not zero. Funds transfer service providers will consider such costs and benefits before deciding to connect.
