RTGS (Real-Time Gross Settlement)
Real-Time Gross Settlement (RTGS) is an RBI-operated high-value interbank payment system that settles each fund transfer instruction individually and immediately on a gross (non-netted) basis, with a minimum transaction amount of Rs 2 lakh and 24×7 availability since December 2020.
RTGS was introduced in India on 26 March 2004 by the RBI as a systemically critical payment infrastructure for large-value, time-sensitive fund transfers. The defining characteristics of RTGS are the real-time settlement (each transaction is settled individually as it is received, not deferred to a batch) and gross settlement (each payment is settled for its full value without netting against other payments), eliminating the settlement risk inherent in deferred net settlement systems like NEFT.
The minimum transaction threshold for RTGS is Rs 2 lakh, with no upper limit, making it the preferred channel for large property purchases, bulk corporate payments, capital market settlements, and interbank money market transactions. The mandatory lower bound ensures RTGS handles genuinely large-value flows and does not compete with NEFT and IMPS for retail transactions.
RTGS was extended to 24×7 operations in December 2020, making India one of the few countries to offer round-the-clock real-time gross settlement for high-value payments. Prior to this, RTGS operated from 7:00 AM to 6:00 PM on bank working days, creating settlement risk in overnight and weekend periods. The extension to 24×7 aligned Indian payment infrastructure with international best practices and supported continuous trading in money markets.
The RTGS system is technically underpinned by a queue management mechanism and an intraday liquidity facility. When a bank's settlement account has insufficient funds at the time a payment instruction is received, the instruction enters a queue and settles when sufficient funds become available — either through incoming payments or by drawing on intraday credit from the RBI collateralised by government securities. This prevents settlement failures while managing systemic credit risk.
Charges for RTGS were abolished for customers in December 2019 by the RBI, removing the fee barrier to digital payment adoption. Banks may charge corporates minimal fees. Savings account holders are typically not charged for RTGS transactions initiated through internet or mobile banking.
For the financial system, RTGS is the backbone of India's large-value payment infrastructure — it settles interbank money market deals, securities settlement through Clearing Corporation of India (CCIL), and government securities auctions. The daily RTGS transaction value consistently exceeds Rs 100–200 lakh crore, reflecting its dominance in the high-value segment.
