MUMBAI: UPI (Unified Payments Interface) transactions in September 2025 continued to show strong momentum, with growth evident in both daily transaction counts and values. While the total number of transactions for the month dipped slightly compared to August, the average daily dataโadjusted for the shorter 30-day Septemberโindicates a clear upward trend in activity on the platform.UPI processed 19.63 billion transactions in September, marginally lower than the 20.01 billion recorded in August. In value terms, the platform saw Rs 24.90 lakh crore transacted, almost flat compared to Rs 24.85 lakh crore in August. On a month-on-month basis, this translated into a 1.9% decline in volume but a 0.2% increase in value. The fall in aggregate numbers was largely due to September having one fewer day than August, making the daily averages more representative of underlying growth.On an average daily basis, UPI handled 654 million transactions worth Rs 83,000 crore each day in September. This marked a 1.37% increase in daily transaction count compared to Augustโs 645 million and a sharper 3.54% rise in daily value from Rs 80,160 crore. The stronger rise in value relative to volume indicates a growth in average ticket size, with users transacting higher amounts per payment in September. Julyโs daily averages were lower at 628 million transactions and Rs 80,900 crore, showing a clear three-month progression.The year-on-year picture remains more robust. Septemberโs total transaction volume was 31% higher than the same month last year, while August had posted 34% growth. In value terms, both August and September registered 21% growth over their respective 2024 levels. These double-digit gains underscore the platformโs continued expansion and deepening integration into everyday payments.
