Through history and the way that card payments have been designed, the action of clearing a payment and settling the payment became inextricably intertwined: one could just not clear a payment without also settling it. It was the only way to implement a multi-party payment model with limited resources in days gone by. When a customer from a different bank to the one that the merchant banks at pays, the merchant needs to know that that specific payment will ultimately end up in the right bank account.
The process of moving money from one bank to another, effectively for every payment made, is called settlement and through the decades it evolved to become one of the most complex systems in the payment world. It also contributes significantly to the cost of a payment. In order to be able to verify that every payment has been settled (individually), a complex structure of processes, reconciliation and managing exceptions was developed and is now in operation.
But what if we can decouple the settlement of a payment from the payment itself?
In this scenario, the money that a merchant makes from payments, will accumulate at the bank of the customer that purchased goods at the merchant. After a while, the merchant may have quite a tidy sum at another bank (or probably other banks), that represents the sum of all the payments received from clients from that bank. If it is a high volume business, the amount could be made up of thousands or even hundreds of thousands of transaction that were conducted in a short time.
If the merchant had the right tools, this money could then be transferred to the bank of choice of the merchant. The intervals of transferring the money, the logic and the amounts can be adjusted to support the needs of the merchant and can be totally decoupled from the actual payments. This would be called sweeping cash from one bank to another and would eliminate the need for settlement completely.
In a next post, I will discuss the merits of such a system and why it would make sense to consider deploying something like this.
