8.3.3.2 Large Unexpected Payments

This assumption allows introduction of unforeseen large payments in usual working day. The large payments can be either receipts or obligations or both. Introduction of large payments suddenly within the bank’s payment system causes a scenario of liquidity stress whereby the bank has to arrange such funds in very short notice. The assumptions allows the user to specify the payment system affected, the time bucket at which the payment(s) is introduced and the amount. The amounts introduced are included in the time buckets as specified in the assumption.

As with other intraday assumptions, all the intraday metrics are calculated post application of the assumption through a Stress Run.

The following is an example for this assumption:

This example contains actual payments made through a particular payment system and the impact of the introduction of a large payment within the other payments.

Actual payments with time stamp are as follows:

Table 7-43 Payment details

Payments made Payment system Time stamp Time bucket - 15 minutes
568 PS 1 12:08 12:01-12:15
876 PS 1 12:09 12:01-12:15
654 PS 1 12:12 12:01-12:15
655 PS 1 12:30 12:16-12:30
673 PS 1 12:31 12:31-12:45
890 PS 1 12:32 12:31-12:45
123 PS 1 12:44 12:31-12:45
876 PS 1 12:45 12:31-12:45

Time bucket is defined as follows:

  • Level 0: 1 minute
  • Level 1: 15 minutes interval.

The bucketed payments at level 1 are as follows:

Table 7-44 Payment details - level 1

Time bucket Payments made
12:01-12:15 2098
12:16-12:30 655
12:31-12:45 2562

Business assumption is defined as follows:

  • Based on: Payments made
  • Payment system: PS1
  • Time bucket: Level 1- 12:16 to 12:30
  • Amount: 6765

The new bucketed payments after the application of the assumption are as follows:

Table 7-45 Payment details

Time bucket Payments made
12:01-12:15 2098
12:16-12:30 7420
12:31-12:45 2562

The new payment can be introduced at any level of time bucket. In the above example, it is introduced in Level 1 of the definition.
