The Reserve Bank of India (RBI) introduced the Digital Payments Index (DPI) in January 2021 to measure the extent and growth of digitization in the Indian payment ecosystem. With March 2018 as the base year, the RBI-DPI provides a comprehensive framework for assessing the country’s progress toward adopting and implementing digital payment systems. This index tracks changes in the digital payment infrastructure, usage, and consumer behaviour over time, offering policymakers and stakeholders valuable insights into the performance and challenges of digital payment adoption in India.
