Guides

End-to-end explanations of the processes behind the messages: who sends what to whom, in which order, and what each status means. Every guide links to the message and code pages and has examples you can open in the parser.

• The securities settlement lifecycle, message by message

  How a securities trade settles: MT540 to MT543 instructions, matching, MT548 statuses, MT544 to MT547 confirmations, statements and their sese equivalents.

• Settlement fails: reading MT548 and sese.024 to fix them faster

  Triage for unmatched, pending and failing trades: which MT548 or sese.024 status and reason you have, what it means, who must act, and where the fix is explained.

• Securities settlement messaging in the GCC and Egypt, market by market

  Which depository, clearing house and message standard each market uses: Saudi Arabia (Edaa), UAE, Kuwait, Qatar, Oman, Bahrain and Egypt, with sources.

• The corporate action lifecycle, from announcement to payment

  Corporate actions from announcement to payment: MAND, CHOS and VOLU events, key dates, MT564 to MT568 and seev.031/033/036, with example messages.

• How to read a custody statement (MT535, MT536, MT537 and semt.002/017)

  Read and reconcile custody statements: MT535 holdings, MT536 transactions, MT537 pending items and semt.002/017, balances explained, full MT535 example.

• ISO 15022 vs ISO 20022 for securities: what the payments switch changed and what it did not

  Why MT540-MT548, MT535 and MT564 stay in use after the November 2025 payments switch, where ISO 20022 is already required, and the MT to MX map.

• Payment message flow: serial vs cover (MT103, MT202COV, pacs.008, pacs.009 COV)

  How a cross-border payment travels: serial MT103 chains vs MT103 plus MT202COV cover, the pacs.008 and pacs.009 COV equivalents, UETR and reimbursement.

• MT to MX: what changed for payments in November 2025

  What the end of MT/MX coexistence on 22 November 2025 changed: which MT payments moved to ISO 20022, contingency conversion, what still runs on MT, and the dates after 2025.

• CBPR+: cross-border payments and reporting on ISO 20022

  What CBPR+ is, which ISO 20022 messages it covers (pacs.008, pacs.009, pacs.002, pacs.004, camt.053 and more), its key rules and the 2023 to 2027 timeline.

• HVPS+: ISO 20022 in high-value payment systems

  What HVPS+ is, how it differs from CBPR+, which messages it uses, and when T2, Fedwire, Lynx, HVCS and other high-value systems moved to ISO 20022.

• Swift gpi and the UETR: how a payment is tracked from end to end

  How Swift gpi tracks cross-border payments with the UETR: where the UETR sits in MT103 field 121 and pacs.008, the status codes banks report, and stop and recall.
