Recalculate after a default - Lerian

Adjust the cycle when a participant with a net debit does not deposit the full amount, whether it is another participant or your own institution.

This flow is a suggested reading of the Núclea and BACEN manuals. The manuals prevail over this page. Your institution, as the participant, validates the flow and implements it on the Lerian APIs. See how to read the diagrams.

Participants

Your institution. The participant that runs the journey and books its effects.
Lerian. Lerian SLC, Lerian SILOC and Lerian SPB. They exchange the messages with Núclea and STR, and expose the API and the events your institution uses.
Núclea. Runs the SLC and SILOC clearinghouses and their settlement windows.
STR (BACEN). The BACEN reserve transfer system. It moves the money between reserve accounts.

Recalculated cycle

Recalculate after a default: Recalculated cycle

#	From	To	Message	Lerian API	What happens
1	Núclea	Núclea	Internal step		At the end of the deposit window, Núclea excludes the defaulter and recalculates the balances.
2	Núclea	Lerian	`LDL0021`		Núclea sends a new request with the recalculated balance and a new deadline.
3	Lerian	Your institution	Lerian API	Event `clearing.cycle_recalculated`	Lerian publishes the recalculated cycle with the new amount and deadline.
4	Your institution	Lerian	Lerian API	Pending	If your institution is a debtor, command the new amount or the difference within the new deadline.
5	Lerian	STR (BACEN)	`LDL0022`	Pending	Lerian sends the deposit to STR.
6	STR (BACEN)	Lerian	`LDL0022R1`	Pending	STR returns the result of the entry.
7	Núclea	STR (BACEN)	`LDL0020`		At settlement time, Núclea orders the transfer to the creditors.
8	STR (BACEN)	Lerian	`LDL0020R2`		If your institution is a creditor, STR reports the credit in its reserve account.
9	Lerian	Your institution	Lerian API	Pending	Lerian publishes the card cycle credit.
10	Núclea	STR (BACEN)	`LDL0006`		If your institution deposited more than the new amount, Núclea refunds the excess.

12	Lerian	Your institution	Lerian API	Pending	Lerian publishes the refund.

Until the deposit through Lerian is available, your institution sends LDL0022 on its own STR connection and records the result with POST /v1/funding/settlement-instructions/{instructionId}/ack.
