What is the difference between MT541 and MT540?

Both receive securities. An MT541 pays cash in exchange (receive against payment), an MT540 receives free of payment, with no cash moving through the settlement system, for example on a transfer between custodians.

Which MT541 fields must match the seller’s MT543?

In T2S: the ISIN, trade date, settlement date, quantity, the delivering and receiving agents, the CSD of each, and the settlement currency and amount (within a small tolerance). The direction and payment type are given by the two message types. Other CSDs use very similar lists.

How do I quote a bond quantity in an MT541?

Use the face amount with the FAMT code, for example :36B::SETT//FAMT/500000,. UNIT is for shares and fund units. For amortising debt some markets also need AMOR in a second 36B::SETT.

Does the MT541 settlement amount include accrued interest?

Yes for bonds: 19A::SETT is the cash that actually moves, so it includes accrued interest and any costs. You can show the parts in separate E3 blocks (19A::DEAL, 19A::ACRU) and flag it with 17B::ACRU//Y.

What confirms that an MT541 settled?

An MT545 receive against payment confirmation from the custodian, after MT548 status messages reporting acceptance, matching and any pending reasons.

MT541 Receive Against Payment

Written and maintained by ZagTrader. Last reviewed 21 October 2026. How this page is sourced and checked

The MT541 is the instruction an account owner sends to its custodian to receive securities from a counterparty and pay for them at the same time (receive versus payment). Brokers, asset managers and global custodians send it on trade date for every purchase, and it must match the seller’s MT543 at the CSD before anything settles.

When MT541 is used

An MT541 settles the buyer’s side of a trade. It tells the account servicer which securities to receive into which account, from whom (the delivering agent at the place of settlement), on which date, and how much cash to pay in exchange. The cash leaves the account only when the securities arrive.

The four settlement instructions form a two-by-two grid. Direction: receive or deliver. Cash: free of payment (FOP) or against payment (DVP for a delivery, RVP for a receipt). MT540 is receive free, MT541 receive against payment, MT542 deliver free and MT543 deliver against payment. A trade settles with one instruction from each side: the seller’s custodian receives an MT543 and the buyer’s custodian an MT541, and the CSD matches the two settlement instructions they produce. A free transfer pairs an MT542 with an MT540 in the same way.

The sender is the account owner and the receiver its account servicer. The account owner can be a broker-dealer or an asset manager with an account at its custodian, or a global custodian instructing its local sub-custodian on behalf of a client. The account servicer checks the instruction, turns it into a settlement instruction in the local CSD (or the ICSD) and reports back with MT548 status messages and, once the securities move, the MT545 confirmation.

Send the instruction on trade date, as soon as the trade is confirmed or affirmed, and before the account servicer’s cut-off, which sits ahead of the CSD’s own matching and settlement deadlines. Early instructions give both sides time to fix a mismatch before the intended settlement date. In the US the standard cycle has been T+1 since May 2024, and in the EU late settlement costs cash penalties under the CSD Regulation, so an instruction sent on the evening before settlement date is often already too late. A status reason LATE (market deadline missed) or ADEA (servicer deadline missed) in the MT548 tells you the instruction arrived after a cut-off.

Field 23G says what the message does. NEWM is a new instruction. CANC cancels an instruction sent earlier: put the SEME of the original in 20C::PREV in sequence A1, and repeat the details of the original so the servicer can find it. There is no amendment function: to change a matching field, cancel and send a new instruction with a new reference. Attributes that are not matched, such as a hold or the partial settlement flag, can often be changed with an MT530 transaction processing command where the servicer supports it. PREA pre-advises an instruction that will follow; servicers that support hold and release keep it on hold until a NEWM arrives that quotes it in 20C::PREA (status reason PREA while it waits). Check your servicer’s guide, since support for PREA differs.

The settlement chain sits in sequence E1, one party per occurrence, and is the part most often wrong. PSET is the BIC of the CSD or ICSD where the securities move. DEAG is the counterparty’s participant in that CSD; it is the one party (besides PSET) the network insists on. Further out come the counterparty’s intermediaries and custodian (DEI1, DEI2, DECU) and its client (SELL). Your own side (REAG and BUYR) is optional: the servicer knows it from your safekeeping account. Take the counterparty’s chain from its standing settlement instructions, not from memory.

What the CSD compares. In T2S (the ECB’s matching guide) the mandatory matching fields are: payment type (free or against payment) and direction (receive or deliver), both given by the message type; the ISIN (35B); trade date (98a::TRAD); intended settlement date (98a::SETT); quantity (36B::SETT); the delivering and receiving parties (95a::DEAG and REAG); the CSD of each party (PSET or derived from the account); and, for against payment, the currency and settlement amount (19A::SETT), within a tolerance. Additional matching fields, which must match once either side fills them, are the opt-out indicator (22F::STCO//NOMC) and the cum or ex indicator (22F::TTCO with CCPN or XCPN). Optional matching fields, compared only when both sides send them, are the common reference (20C::COMM), the client of each participant and their securities accounts. Other CSDs use similar lists. When the two sides differ, the MT548 reports NMAT with a reason such as DDAT, DQUA, DSEC, DMON, DEPT or ICAG; see why an instruction is unmatched.

After sending, expect a chain of MT548 messages: accepted (PACK) or rejected (REJT), then matched (MACH) or unmatched (NMAT), then pending (PEND) or failing (PENF) with a reason such as MONY (not enough cash), and finally the MT545 confirmation on settlement. A cancellation request is answered with CAND (cancelled) or CANP (cancellation pending). The settlement lifecycle guide walks through the whole flow.

MT541 format: sequences and fields

Sequence AGeneral InformationMandatory

Identifies the instruction and says what to do with it (new, cancel, pre-advice).

Tag	Qualifier	Name	Status	Format	Meaning
16R		Start of block	M	GENL	Opens the General Information block.
20C	SEME	Sender's Message Reference	M	:4!c//16x	Your own unique reference for this instruction (16 characters at most). The account servicer quotes it in every MT548 status message and in the MT545 confirmation, so it must be unique per instruction. Do not reuse the reference of a cancelled instruction for its replacement.
23G		Function of the Message	M	4!c[/4!c]	NEWM for a new instruction, CANC to cancel one sent earlier, PREA to pre-advise an instruction that will follow. An optional subfunction marks a copy (COPY), a duplicate (DUPL) or a copy of a duplicate (CODU). Many servicers ask for no subfunction on a live instruction.
98a	PREP	Preparation Date/Time	O	A: :4!c//8!n C: :4!c//8!n6!n E: :4!c//8!n6!n[,3n][/[N]2!n[2!n]]	When the message was created, usually as 98C::PREP with date and time.
99B	SETT	Current Settlement Instruction Number	O	:4!c//3!n	Position of this instruction in a set of linked instructions (for example 001 of 003), used with pools and linked settlement.
99B	TOSE	Total of Linked Settlement Instructions	O	:4!c//3!n	How many instructions the set contains. If TOSE is present, 99B::SETT must be present too (network error E90).
16S		End of block	M	GENL	Closes the General Information block.

Sequence A1LinkagesOptional, repeatable

One occurrence per reference. Field 20C is mandatory in every A1; each 20C row below is one qualifier to choose from. Common qualifiers only.

Tag	Qualifier	Name	Status	Format	Meaning
16R		Start of block	M	LINK	Opens the Linkages block.
22F	LINK	Linkage Type Indicator	O	:4!c/[8c]/4!c	How this instruction depends on the linked one: WITH (settle together), BEFO (settle this one first), AFTE (settle this one after) or INFO (link for information only). Not every servicer or CSD supports every code.

20C	PREV	Previous Message Reference	M	:4!c//16x	The SEME of the instruction you want to cancel. When 23G is CANC, at least one A1 must be present and exactly one of them must carry 20C::PREV (network error E08).
20C	RELA	Related Message Reference	M	:4!c//16x	Reference of a related message, for example a linked instruction or the account servicer’s own reference.
20C	PREA	Preadvice Message Reference	M	:4!c//16x	The SEME of the PREA message that this NEWM follows up. Servicers that hold pre-advised instructions use this link to release them.
20C	COMM	Common Reference	M	:4!c//16x	A reference both counterparties agreed on, such as a trade ID from a confirmation platform. In T2S it is an optional matching field: it may be blank on one side, but if both sides send it, it must be equal.
20C	POOL	Pool Reference	M	:4!c//16x	Groups several instructions that belong together, for example the deliveries that make up one large trade.
20C	TRRF	Deal Reference	M	:4!c//16x	The trade or deal reference from the order or trading system.
36B	PAIR	Quantity of Financial Instrument to be Paired-off	C	:4!c//4!c/15d	Quantity to pair off against the linked instruction. Allowed only when 22F::SETR is PAIR or TURN (network error C50). 36B::TURN works the same way for a turnaround.

25D	MTCH	Matching Status	O	:4!c/[8c]/4!c	MACH says the trade was already matched outside the CSD, for example by a central counterparty or a matching utility; NMAT says it was not. Mostly used by CSD participants. T2S turns an already matched instruction into two instructions.
70E	SPRO	Settlement Instruction Processing Narrative	O	:4!c//10*35x	Free-text processing instructions. Many account servicers route any instruction with narrative to manual handling, so keep it out of automated flows.

With DBNM, E1 no longer needs PSET and DEAG, but a SELL party is required (network error E70), and with VEND a vendor in sequence F (D71).
22F	STAM	Stamp Duty Indicator	O	:4!c/[8c]/4!c	Stamp duty treatment in markets that charge it, usually with a market code list in the data source scheme part of the field.

Sequence E1Settlement PartiesMandatory, repeatable

One occurrence per party, each holding one 95a party field (the field is mandatory in every occurrence; the qualifier is your choice). Network rules decide which parties must appear across the occurrences. The delivering chain runs from the CSD outwards: PSET, DEAG, DEI1, DEI2, DECU, SELL. Common qualifiers only.

Unless 22F::DBNM is used, one E1 must hold PSET and another must hold DEAG (network error E93). The occurrence with PSET must not carry 97a::SAFE (E52). A place of settlement that differs from the counterparty’s gives reason DEPT.

T2S compares the client of each participant as an optional matching field; which MT party carries it depends on the chain and the CSD’s mapping. Required when 22F::DBNM is used (E70).
97a	SAFE	Safekeeping Account	C	A: :4!c//35x B: :4!c/[8c]/4!c/35x	Account of the party in the same occurrence, for example the counterparty’s account at the CSD in the DEAG occurrence. Not allowed in the PSET occurrence (E52). In T2S the securities account of each party is an optional matching field.

One E3 must carry it (network error E92). A mandatory matching field: CSDs accept only a small difference (in T2S EUR 2 up to EUR 100,000 and EUR 25 above, per the ECB’s matching guide); beyond that the instruction stays unmatched with reason DMON, and a different currency gives NCRR.

Format notation: n digits, a upper-case letters, c upper-case letters and digits, x any character of the Swift character set, d a decimal number with a comma, ! fixed length, [ ] optional, 4*35x up to 4 lines of 35 characters. M mandatory, O optional, C conditional (a rule decides).

Rules worth knowing

Sequences A, B, C and E are mandatory, and E1 must occur at least once. A1, B1, C1, D, E2 and F are optional. E3 (amounts) is mandatory in an against payment instruction. There is no E1a: the party chain is built by repeating E1.
Unless 22F::DBNM is present in sequence E, one E1 occurrence must contain 95a::DEAG and another must contain 95a::PSET (network error E93).
With 22F::DBNM present, an E1 occurrence must contain 95a::SELL (E70); with 22F::DBNM//VEND, sequence F must contain 95a::VEND (D71).
Each party qualifier (BUYR, SELL, DEAG, REAG, DECU, RECU, DEI1, DEI2, REI1, REI2, PSET in E1, the cash parties in E2, and the parties of sequence F except INVE) may appear only once in the message (E84).
The chain must be complete going outwards: DEI2 needs DEI1, DEI1 needs DECU, DECU needs SELL; on the receiving side REI2 needs REI1, REI1 needs RECU, RECU needs BUYR (E86).
The E1 occurrence that holds PSET cannot also hold 97a::SAFE (E52).
When 23G is CANC, at least one A1 must be present and 20C::PREV must appear in exactly one of them (E08).
One E3 occurrence must contain the settlement amount 19A::SETT (E92). No amount qualifier may appear in more than one E3 (E87).
A value date (98a::VALU) is allowed only with 22F::STCO//SPST and with 19A::SETT in the same E3 (C28). An exchange rate (92B::EXCH) requires 19A::RESU in the same E3, and RESU is not allowed without a rate (E62).
36B::SETT may appear at most twice, and then once with FAMT and once with AMOR (C71). A quantity in sequence A1 (36B::PAIR or TURN) is allowed only with 22F::SETR//PAIR or TURN (C50). If 99B::TOSE is present, 99B::SETT must be present (E90).
The rule numbers (C1, C2 and so on) differ between MT540, MT541, MT542 and MT543 and between standards releases, so search for the error code, not the rule number. Newer releases added further rules, for example on the LEI options of 94a and 95a.

MT541 example

A London asset manager (FUNDGB2LXXX) bought EUR 500,000 nominal of a 4% bond (XS00ZAGT0013) at 101.25% from a broker (BRKRGB2LXXX). It instructs its custodian CUSTGB2LXXX to receive the bond at the ICSD (ICSDLULLXXX) against EUR 509,138.89: the deal amount of EUR 506,250.00 plus 52 days of accrued interest, EUR 2,888.89 (30/360 basis).

The broker’s custodian sends the mirror image, an MT543 with REAG CUSTGB2LXXX and the same ISIN, dates, face amount and settlement amount.

All BICs, accounts, the ISIN and the bond name are made up. The ISIN carries a valid check digit.

Common errors and rejects

Network reject: no DEAG or no PSET (E93)
Without 22F::DBNM, one E1 must name the delivering agent and another the place of settlement. The network rejects the message otherwise. Put each party in its own E1, and keep 97a::SAFE out of the PSET occurrence (E52).
Unknown safekeeping or cash account (REJT, SAFE)
The 97a::SAFE in sequence C is not an open account the custodian holds for you, so the instruction is rejected with reason SAFE. A cash account in 97a::CASH that does not belong to the same client is a common variant of the same problem.
How to fix it
Wrong place of settlement (DEPT)
The seller settles at a different CSD or ICSD from the one in your PSET, or the BIC is wrong. The instruction is rejected or stays unmatched with reason DEPT. Check the seller’s standing settlement instructions and your custodian’s market guide, especially when one side settles at a CSD and the other at an ICSD.
How to fix it
Settlement amount mismatch (NMAT, DMON)
The most common bond mismatch: one side computed accrued interest with a different day count or number of days, or used the clean amount. If the difference is above the CSD’s tolerance, the instruction stays NMAT with reason DMON. Recalculate from the confirmation and re-instruct the side that is wrong.
How to fix it
Wrong quantity type or SETR code (DQUA, SETR)
Sending a bond quantity as UNIT instead of FAMT gives DQUA. A 22F::SETR code that the market does not support, or that differs from the seller’s where it is compared, gives reason SETR.
How to fix it
Late instruction or not enough cash (LATE, MONY)
An instruction received after the cut-off is reported with LATE or ADEA. A matched receipt that cannot be funded on settlement date goes pending with MONY until cash is credited.
How to fix it

MT541 in ISO 20022

In ISO 20022 one message, sese.023 (Securities Settlement Transaction Instruction), replaces all four instructions. The direction and the payment type become data elements: an MT541 is a sese.023 with SttlmTpAndAddtlParams/SctiesMvmntTp = RECE and SttlmTpAndAddtlParams/Pmt = APMT. The status message MT548 becomes sese.024, the confirmation MT545 becomes sese.025, and a cancellation is a separate message, sese.020 (Securities Transaction Cancellation Request), instead of 23G CANC.

Securities messages (category 5) were not part of the November 2025 end of MT/MX coexistence for cross-border payments, and MT540 to MT543 remain in use on FIN alongside their ISO 20022 equivalents. T2S and the CSD participants connected directly to it work in ISO 20022 (sese and semt messages); many custodians and CSDs accept both formats and translate between them. See how the securities migration differs from payments.

MT541 questions

What is the difference between MT541 and MT540?: Both receive securities. An MT541 pays cash in exchange (receive against payment), an MT540 receives free of payment, with no cash moving through the settlement system, for example on a transfer between custodians.
Which MT541 fields must match the seller’s MT543?: In T2S: the ISIN, trade date, settlement date, quantity, the delivering and receiving agents, the CSD of each, and the settlement currency and amount (within a small tolerance). The direction and payment type are given by the two message types. Other CSDs use very similar lists.
How do I quote a bond quantity in an MT541?: Use the face amount with the FAMT code, for example :36B::SETT//FAMT/500000,. UNIT is for shares and fund units. For amortising debt some markets also need AMOR in a second 36B::SETT.
Does the MT541 settlement amount include accrued interest?: Yes for bonds: 19A::SETT is the cash that actually moves, so it includes accrued interest and any costs. You can show the parts in separate E3 blocks (19A::DEAL, 19A::ACRU) and flag it with 17B::ACRU//Y.
What confirms that an MT541 settled?: An MT545 receive against payment confirmation from the custodian, after MT548 status messages reporting acceptance, matching and any pending reasons.
What is the ISO 20022 equivalent of MT541?: sese.023 with the securities movement type RECE and payment type APMT.

The trading side of the trade: FIX

Before a settlement instruction is sent, the trade is usually executed, allocated and confirmed over FIX, and the instruction must copy what was agreed there. Read those messages on the free ZagTrader FIX Parser:

From FIX execution to settlement: which FIX field becomes which settlement field, and where breaks start
Allocation Instruction (35=J): how a block trade is split across accounts
Confirmation (35=AK): the confirmed economics per allocation
Settlement Instructions (35=T): standing settlement instructions over FIX
