What role did the Unified Payments Interface (UPI) play in the growth of digital payments in India between 2016 and 2023?

The Unified Payments Interface (UPI) significantly contributed to the growth of digital payments in India between 2016 and 2023 by facilitating a rapid increase in digital retail payments. During this period, digital payments experienced a compounded annual growth rate (CAGR) of 51% in volume and 27% in value, largely attributed to UPI's convenience and security.

The UPI has been a driving force behind the substantial rise in digital payments in India, with its implementation aligning with government initiatives aimed at promoting a cashless economy. The UPI's role was particularly pronounced during the demonetization period and the COVID-19 pandemic, which accelerated the shift towards digital transactions. This transition not only formalized the economy but also improved tax compliance and increased Goods and Services Tax (GST) collections, demonstrating UPI's impact on both consumer behavior and economic policy.
