UPI Settlement Process

-

 We will look at settlements and understand how money exchanges hands.

In the last part, we debited Alice’s account and credited that money to Bob’s account. Alice banks with HDFC Banks and Bob banks with SBI.

Although, bob received money in his account realtime, their banks didn’t really exchange money.

That’s where the settlement function of NPCI comes into the picture.

Every member bank of UPI needs to have an account with Reserve Bank of India. In short, RBI is the bank of all banks.

In the example we saw, Alice sent Rs. 1000 to Bob. Over time, many more transactions happen. Once in few hours, NPCI combines all the transactions that happened during the last period and creates a bulk settlement file. It creates settlement reports that are customized to every bank and sends it to every member bank involved. All banks do an internal computation to find how much do they owe someone or how much some other bank owes to them.

Let’s take a look at files sent to HDFC and SBI.

In the report sent to HDFC, the net settlement for SBI is at +500 crores. It means that HDFC has received 500 crores in excess of what it sent to SBI.

On the other hand, in the report sent to SBI the net settlement for HDFC stands at -500 crores. It means that SBI has sent 500 crores in excess of what it has received from HDFC.

The conclusion is that HDFC owes SBI 500 crores.

If we recall, both HDFC and SBI have accounts with the RBI (the bank of banks). Now, HDFC issues an authorization to RBI to transfer 500 crores from its account and credit it to SBI’s account. RBI checks the authorization and finally updates the ledger.

The transaction is now complete.

That’s a wrap of the series, now you know how the UPI Payment System works.

SWIFT MT – SERIAL AND COVER METHOD

  SWIFT MT – Serial and Cover Method This is one of the most important articles from SWIFT payments’ perspective and it is critical that you fully understand the concepts laid out here. Payments are cleared and settled via 2 primary methods: Through a payment market infrastructure (PMI) Through correspondent banking Through payment market infrastructure: This is the case where bank A and bank B are direct participants of this PMI aka CSM. IN General usage the concept of serial and cover does not apply here but if you put a gun to my head, I would say is very close to the serial method. Through correspondent banking: This is the case where banks open accounts with each other (Nostro/Vostro) and settle funds directly. The prerequisite here is that banks need to open accounts with each other or in other words they need to have an  accounting relationship  with the other bank. Now, let us try to understand the connection between sending/receiving SWIFT messages and the moveme...

  Payment Engines: I am really excited about this topic as it’s my favorite and the one in which I have the most experience. In this article, we will be discussing about a piece of software called “payment engine” . They are part of the bank’s IT ecosystem and they help banks process hundreds of thousands of payments a day seamlessly. In the previous articles, we discussed the different message types and how banks send these messages to each other. Payment engines help banks to send, receive and process payments. We will discuss only credit transfers here. Direct debits can be parked for the Future. We will approach this subject  without any particular payment engine or message scheme in our minds . Once we get the bigger picture knowing specifics will be much easier. A0501 From a payment engines’ perspective there are 4 types of payments: Incoming Outgoing Book Redirect We will briefly see what these types are and then dive right into the flows. Banks processes each of these ...
