Haruhiko Kuroda: Evolution of payments - payment systems for
"Neoteric Individuals"
Remarks by Mr Haruhiko Kuroda, Governor of the Bank of Japan, at the Fintech
Summit FIN/SUM 2023, Tokyo, 28 March 2023.

Introduction
I am delighted to be given this opportunity to speak to you at the FIN/SUM 2023.
The main theme of this year's FIN/SUM is "Fintech, the era of 'Neoteric Individual."
While the term "neoteric" is open to interpretation, I will be speaking today within the
context of "moving forward" or "evolution."
In a world where information proliferates owing to widespread access to the Internet
and smartphones, the diverse decisions and actions of consumers - neoteric individuals
- are based on the vast array of readily available information. Consequently,
diversification of user needs related to financial services has increased rapidly;
continuing to merely provide uniform services is no longer sufficient for meeting the
various user needs.
Under these circumstances, financial services are undergoing continuous progress and
innovation as they capture cutting-edge technologies and business ideas. The field of
payments, an example of financial services, is no exception. My first opportunity to
speak at the FIN/SUM was in September 2019. Even if we focused exclusively on the
period since, efforts by the private sector toward realizing novel payment services have
proven to be remarkable.
Unbundling of Services and Functions
Of the notable developments in payment services, some have drawn my attention in
particular, the first of which is progress being made in the unbundling of services that
have been provided as tightly coupled thus far.
To give an example, with fintech businesses utilizing payment functions provided by
banks through an open Application Programming Interface (open API), moves to
innovate customer services as well as develop a convenient and comfortable user
experience are growing increasingly common.
Shifting our focus to overseas, various stablecoins circulated on permissionless
blockchains are emerging. This can be considered an unbundling of two payment
functions: one for issuing liabilities, or put differently, settlement assets, and the other
for recording interest in settlement assets.
This unbundling also applies to "programmability," a popular term these days. While
additional functions such as conditional payments have thus far been provided by the
entity in charge of the payment functions, the unbundling of functions allows for a wide
range of entities, including service users, to carry out the programming of such
functions other than core payment functions themselves. This point warrants attention.
Simplification of Payment Arrangements through Creation and
Discharge of Financial Liabilities
The second area of focus is efforts to proceed with the simplification of payment
arrangements, which have involved the creation and discharge of financial liabilities.
For example, many of the Fast Payment Systems introduced overseas in recent years
feature real-time gross settlement between banks. This is a byproduct of technological
advancement allowing for the elimination of the process involving the calculation of net
positions, and further, the replacement of obligations between banks, resulting in the
simplification of arrangements for the creation and discharge of liabilities.
If we take a step back and think, we realize that quite a few of the existing
arrangements have been shaped amid technical constraints in the past. One such case
involves correspondent banking arrangements for cross-border payments, in which
funds were transferred from the payer to the payee through multiple entities, creating
and discharging liabilities in the process. Attempts to utilize stablecoins issued by the
private sector and wholesale central bank digital currency (CBDC) for interbank
settlement in cross-border payments can be considered to have stemmed from the idea
that simplifying the existing banking arrangements would significantly enhance
efficiency.
Emergence of Novel Domains of Economic Activities
The third area warranting attention is the emergence of novel domains of economic
activities. Given that payments discharge any financial obligations resulting from
economic activities, it goes without saying that economic activity and payments are
closely related to each other. With various economic activities taking place online,
online payments will become even more prevalent.
Recently, the terms Web3 and Web 3.0 have become familiar to the ear. While the
implications of these notions may differ from person to person, the Web3 Foundation -
founded by Gavin Wood, who coined the term Web 3.0 - defines it as "a decentralized
and fair internet where users control their own data, identity and destiny."
How such ideas will evolve in reality and how economic activity will be shaped under
those circumstances have yet to be seen. In considering the evolution of payments, it is
necessary to also bear in mind how novel domains of economic activities will emerge
alongside this evolution.
The Roles of Central Bank Money
The evolution of payments that I have just mentioned carries the potential to bring about
enhanced user convenience, new business opportunities, and ultimately, economic
growth. Even amid such notable evolution, however, some things ought to be
maintained.
By this, I am referring to the coexistence of various forms of money. I say this because,
under the appropriate arrangements and regulations, such payment instruments as
cash, bank deposits, electronic money, and stablecoins compete against one another,
building on their respective strengths. Only by doing so can a payment system as a
whole remain safe, efficient, and resilient over the course of time.
Under these circumstances, central bank money, such as cash and central bank
deposits, is expected to assume a leading role in a world where various forms of
privatesector money - including bank deposits, which serve a key function, namely, financial
intermediation - coexist. When central bank money, which provides the unit of account,
is converted without friction to and from other forms of money, this makes it possible to
ensure the uniformity of money; in other words, maintaining a situation where "one yen
is one yen," regardless of payment instrument. Even if novel domains of economic
activities continued to emerge to the extent that payment services were provided in
these unprecedented domains, it would be desirable that the unit of account in such
novel domains was connected with that of the real world.
Closing Remarks
As I bring my remarks to a close, let me briefly touch upon CBDC. Ensuring the
coexistence of CBDC with various other forms of money, and upon doing so, providing
in collaboration with the private sector a payment instrument in digital form that is safe
and usable anywhere, anytime - this is something that we need to and will in fact
achieve in the future. With various options lying before us in terms of how and when to
carry this out, preparing ourselves so as to respond flexibly to any change in
circumstance is indeed the central bank's duty.
From the viewpoint of preparing thoroughly for the future, the Bank of Japan, two years
ago, began its technical experiments for retail CBDC assuming a wide range of users
including individuals and firms. Taking the findings into account, the Bank has decided
to launch a pilot program this April. In the pilot program, we will fully utilize the skills and
insights of private businesses engaged in retail payments or in related technologies
through the soon-to-be established CBDC Forum. We would like to ask for your
continued invaluable support so that the evolution of payments will lead to the
establishment of payment systems for neoteric individuals.
Thank you for your attention.
