RTGS (Real-Time Gross Settlement) is a payment system in which large-value interbank transfers settle continuously and individually in real time, rather than in batches at end of day. Most countries operate an RTGS system as the backbone of their financial infrastructure — examples include Fedwire (US), CHAPS (UK), TARGET2 (EU), and RTGS in India. These systems process high-value transactions where immediate finality is critical.
Unlike batch payment systems (ACH, BACS) that aggregate and net transactions, RTGS settles each transaction individually the moment it is received. Funds are immediately irrevocable — the recipient bank has final, settled funds. This makes RTGS suitable for large transactions (corporate treasury, securities settlement, central bank operations) where settlement finality matters.
Fedwire (US): real-time, business hours, used for $1M+ transactions. CHAPS (UK): real-time, business hours, used for mortgages and large payments. TARGET2 (EU): real-time, processes €2T+ daily. India RTGS: real-time, 24/7 since December 2020, minimum ₹2 lakh ($2,400). Most central banks operate their own RTGS.
RTGS systems are domestic — they don't directly connect to foreign RTGS. International large-value transfers use SWIFT + correspondent banking, with each bank using its domestic RTGS for the final leg. Digital asset rails (Stellar, Tron) achieve RTGS-like instant finality without the correspondent bank overhead.
RTGS: real-time, minimum ₹2 lakh, large value. NEFT: batch processed every 30 minutes, no minimum, smaller amounts. IMPS: real-time, 24/7, up to ₹5 lakh, for retail use. For NRI remittances arriving in India, funds typically clear via NEFT or IMPS at the receiving end, not RTGS.

₹2 lakh (200,000 INR, approximately $2,400). For amounts below ₹2 lakh, NEFT or IMPS is used. India's RTGS operates 24/7.
RTGS settles each transaction individually in real time. NEFT processes in batches every 30 minutes. RTGS has a minimum amount (₹2 lakh in India), NEFT does not.
Indirectly. Each domestic leg of an international transfer may use the local RTGS. But cross-border settlements use SWIFT + correspondent banking, not a direct RTGS-to-RTGS connection between countries.
For consumer remittances, yes. Stablecoins on Stellar or Tron offer RTGS-like instant finality at much lower cost. For institutional/corporate transfers requiring legal certainty and central bank settlement, RTGS remains the standard.
