Why the Indian Central Bank Had to Invent UPI (Unified Payments Interface)

原文:为什么印度央行必须发明UPI(统一支付接口)

Summary of the Key Points

This article discusses how India has addressed the challenges posed by problematic payment bank accounts and wallet companies that threaten the country's financial sovereignty. In the early stages, payment bank accounts became virtually inactive due to the inconvenience of making transfers. Wallet companies, with their user-friendly services, attracted customers, but this led to banks losing deposits, the state losing revenue from seigniorage (the cost of printing currency), the failure of monetary policy, and the government having to bear the consequences in times of economic crisis. Conventional approaches to solving these issues were ineffective. Ultimately, the Reserve Bank of India (RBI) came up with a novel solution using UPI (Unified Payment Interface), allowing internet companies to provide the user experience while keeping funds within the banking system. This approach not only meets users' needs for convenience but also preserves the country's financial sovereignty.

1. Why were early payment bank accounts “inactive”?

In 2014, India introduced payment banks that enabled ordinary people to open accounts, but these accounts remained largely unused until the launch of UPI in 2016. The reason was simple: transferring money was too cumbersome. For example, users had to remember long bank account numbers and IFSC (Indian Financial System Code) branch codes, fill out forms at branches, or use online banking/ATMs, a process that was both time-consuming and not real-time. For those new to digital finance, this was even more inconvenient than using cash, resulting in many accounts remaining inactive.

2. Why is the state so concerned about wallet companies attracting customers?

Wallet companies (non-bank payment services) offer attractive incentives such as “get 10 rupees for every 100 rupees you deposit” or the ability to book taxis and shop online, enticing users to move their money from bank accounts to their wallets. This seemingly competitive behavior actually poses a threat to the country’s financial foundation:

  • Banks become mere payment channels: Money in wallets is no longer considered bank deposits, depriving banks of lending opportunities and limiting their ability to assess customer credit for loans.
  • The state loses seigniorage revenue: The cost of printing 100 rupees is only about 0.1 rupee, with the remaining 99.9 rupees being the state’s “profit” (seigniorage), which could be used for infrastructure projects. If wallet companies create their own virtual currencies, this revenue goes to private entities.
  • Monetary policy becomes ineffective: During economic booms, wallet companies may stimulate spending by offering discounts; during downturns, they may restrict transactions to maximize profits. The state is unable to control these trends effectively.
  • The government bears the risks: If a financial crisis leads to customer withdrawals, the government has to intervene to protect public welfare, meaning private companies benefit while the state suffers losses. This essentially hands over financial control to capitalists.

3. Why didn’t conventional methods work?

The state tried two approaches but both failed:

  • Restricting usage: Forcing users to bank with traditional banks didn’t work; if banking services didn’t improve, users would revert to cash, which is more costly and difficult to regulate (e.g., through tax evasion).
  • Reforming the banking system: State-owned banks dominate the market, and the government wasn’t willing to let them fail. Without pressure, they wouldn’t make necessary changes. Moreover, upgrading their outdated systems would take years, by which time wallet companies would have monopolized the market.

4. How does UPI achieve a balance?

The RBI found a third way: UPI creates a unified payment platform that solves these issues while maintaining financial sovereignty:

  • Maintaining financial sovereignty: Regardless of the convenience of payment methods, money must remain in bank accounts, as banks are responsible for currency creation and capital management.
  • Innovative approach: A central technology layer is used to allow internet companies (like Paytm and Google Pay) to provide user interfaces (e.g., by registering virtual addresses), but all transaction commands must go through UPI. This ensures that users can register in minutes and transfer money quickly using virtual addresses, while banks maintain control over funds. Wallet companies can offer additional services, and the RBI retains regulatory authority. Everyone benefits.

5. The significance of UPI beyond its functionality

The design of UPI is more than a technical solution; it reflects national policy:

  • For international businesses: Companies operating in India must integrate UPI; trying to replicate China’s model of wallet companies (moving money directly to their own accounts) is not allowed.
  • For ordinary citizens: Payment systems reflect the balance of power in finance. Whoever controls payment also controls the flow of currency and economic activities. In other words, while payment tools make shopping easier, they influence a country’s ability to manage and allocate funds effectively, which affects everyday life (e.g., infrastructure development, tax policies, price stability).

This article highlights that payment systems are not trivial matters but crucial for maintaining financial sovereignty. The success of UPI demonstrates how technology can be used to balance user experience with national interests.
