The correct answer is Real Time Gross Settlement Explanation & Key Takeaways: • Real Time Gross Settlement (RTGS) is a system where the transfer of money or securities happens from one bank to another on a "real-time" and on a "gross" basis. • This is the fastest possible money transfer system through the banking channel. • RTGS is primarily meant for large value transactions that require and receive immediate clearing. • The minimum amount to be remitted through RTGS is ₹2 lakh with no upper limit. • RTGS transactions are processed continuously throughout the RTGS business hours. Related Concepts: • The Reserve Bank of India (RBI) maintains the RTGS system. • RTGS is different from NEFT (National Electronic Funds Transfer) where the transactions are processed in batches and there is no minimum or maximum limit on the amount that can be transferred. • RTGS is available on all working days of the week except Sundays and bank holidays. • The RTGS service window for customer's transactions is available from 7:00 AM to 6:00 PM on weekdays and from 7:00 AM to 1:00 PM on Saturdays. • RTGS ensures that funds are transferred without any delay, making it an essential part of the financial system.
