How Bank-To-Bank Funds Verification Works: MT799, MT199, POF Letters And Other Options
Bank-to-bank funds verification is used when a seller, lender, issuing bank, beneficiary, escrow agent, broker, commodity counterparty, acquisition seller, or project owner wants confirmation that a buyer or applicant has credible financial capacity. The right format depends on the transaction stage, the bank’s policy, the counterparty’s requirement, the amount, the source of funds, the requested wording, and whether the counterparty needs soft comfort, formal proof of funds, blocked funds, escrow evidence, or an operative bank instrument.
Bank-to-bank funds verification is often requested in commodity trades, business acquisitions, standby letter of credit arrangements, documentary letter of credit transactions, project finance negotiations, equipment purchases, real estate acquisitions, and other high-value commercial transactions. The phrase sounds simple, but several very different tools are used in practice: MT799, MT199, bank comfort letters, proof of funds letters, ready willing and able letters, blocked funds letters, escrow confirmations, custodial account confirmations, securities portfolio statements, and operative instruments such as MT760 standby letters of credit or MT700 documentary credits.
The first issue is purpose. A counterparty may want to know that funds exist. A supplier may want comfort before issuing a proforma invoice. A bank may want to know that margin is available before issuing a standby letter of credit. A seller may want evidence that an acquisition buyer can close. A receiving bank may want authenticated communication before accepting a bank instrument. Each case needs a different verification format.
Financely helps clients select and coordinate the right proof format for real commercial transactions. We support proof of funds, BCL, RWA, MT199, MT799, bank-to-bank messaging, SBLC readiness, documentary credit readiness, and structured trade finance verification where the file has a legitimate commercial purpose. For related services, see our pages on proof of funds, bank comfort letter, MT199 and MT799 support , MT799 bank-to-bank communication , and MT199 in trade finance.
What Bank-To-Bank Funds Verification Actually Verifies
Funds verification can confirm different things depending on wording. A bank may confirm that a client maintains a relationship, has funds on deposit, has access to a credit line, is ready to issue an instrument, has blocked funds for a transaction, or has instructed the bank to communicate with another bank. These are not the same commercial statement.
A verification message or letter should state exactly what is being confirmed. “Client is financially capable” is weaker than “client has available funds in the amount of USD X as of date Y.” “Ready, willing and able” is softer than a blocked funds confirmation. A bank comfort letter is not a payment undertaking. An MT799 is not a fund transfer. An MT760 SBLC or bank guarantee is different because it can create an independent bank undertaking if properly issued and accepted.
| Verification Type | What It Can Show | What It Does Not Do |
|---|---|---|
| MT799 | Authenticated bank-to-bank free-format communication about readiness, proof of funds, transaction intent, account capability, or pre-advice. | It does not transfer funds, guarantee payment, or create an operative SBLC by itself. |
| MT199 | Authenticated free-format bank message often used for commercial communication, clarification, readiness, or supporting proof communication. | It is not usually the legal core of the transaction and does not replace an operative credit instrument. |
| Bank Comfort Letter | Bank-issued letter confirming financial standing, account relationship, credit line, or general capability depending on wording. | It normally does not guarantee payment to the seller or beneficiary. |
| Proof Of Funds Letter | Written confirmation that funds are available, subject to the bank’s wording and policy. | It may not block the funds, reserve them, or commit the bank to pay unless expressly structured that way. |
| Blocked Funds Letter | Confirmation that funds are held or restricted for a defined purpose, if the bank agrees to issue that wording. | It still needs legal review, release conditions, account control mechanics, and counterparty acceptance. |
| Escrow Confirmation | Confirmation that funds are held by an escrow agent under agreed release conditions. | It is only as strong as the escrow agreement, account bank, agent, and release mechanics. |
| MT760 SBLC Or Guarantee | Operative bank undertaking if issued correctly through SWIFT and accepted under the agreed terms. | It is not just verification. It is a bank instrument with draw conditions, expiry, wording, rules, and fees. |
How MT799 Works In Funds Verification
MT799 is a SWIFT Category 7 free-format message used between banks. In proof of funds and trade finance contexts, it is commonly used to communicate readiness, confirm account capability, pre-advise a transaction, support proof of funds, or coordinate before an operative instrument such as an MT760 standby letter of credit or bank guarantee is issued.
The practical value of an MT799 depends on the sending bank, receiving bank, wording, client authority, transaction reference, and commercial context. A serious MT799 should be sent bank-to-bank, reference a real transaction, state a specific purpose, identify the parties, and avoid vague claims that a receiving bank cannot rely on.
Important distinction: an MT799 can communicate a bank’s position or client readiness, but it does not move money. If the counterparty needs an enforceable payment obligation, the discussion usually moves to an SBLC, bank guarantee, documentary credit, escrow, blocked funds, or direct payment mechanism.
MT799 Versus MT760 And MT700
MT799 often appears before the operative instrument. It may pre-advise readiness, confirm that a bank is prepared to proceed, or support the receiving bank’s internal checks. MT760 and MT700 are different because they relate to operative trade finance instruments.
An MT760 SWIFT message is used for bank guarantees and standby letters of credit. An MT700 documentary letter of credit supports payment against compliant documents in a shipment-driven trade. Those messages are tied to bank undertakings, draw mechanics, documentary presentation rules, expiry dates, charges, and legal obligations. MT799 is communication. MT760 and MT700 sit closer to the enforceable instrument layer.
MT799
Used for authenticated free-format bank communication, pre-advice, proof support, readiness messages, or transaction coordination before a binding instrument is issued.
MT199
Used for authenticated free-format communication in a different message category. It may support transaction communication, clarification, or proof-related dialogue where banks accept it.
MT760
Used for standby letters of credit and bank guarantees. This is the message category counterparties usually look to when they need an operative undertaking.
MT700
Used for documentary credits in trade transactions. This supports payment against compliant documents such as invoices, bills of lading, inspection certificates, and insurance documents.
Other Options For Bank-To-Bank Funds Verification
MT799 is not always the best option. Some banks will not send it for proof of funds. Some receiving banks do not want it. Some transactions are better served by a bank letter, escrow confirmation, blocked funds structure, account statement, custodian letter, documentary credit, or standby letter of credit.
| Option | Best Fit | Key Control Point |
|---|---|---|
| Bank Comfort Letter | Early-stage transaction comfort, supplier screening, acquisition seller comfort, or pre-closing credibility. | Wording must avoid overstating payment commitment. |
| Proof Of Funds Letter | Commercial transactions where the counterparty needs written evidence that funds exist. | Letter should be bank-issued, current, specific, and directly verifiable. |
| Blocked Funds Letter | Transactions where the counterparty needs comfort that funds are reserved or restricted. | Blocking mechanism, release conditions, account control, and bank authority must be clear. |
| Escrow Confirmation | Acquisitions, commodity trades, supplier deposits, and closing transactions with conditional release. | Escrow agreement, release triggers, account bank, and parties must be reviewed. |
| Custodial Account Letter | Securities-backed transactions, investor funds, private credit, or capital stack verification. | Custodian identity, asset liquidity, encumbrances, and authority to use funds must be checked. |
| Securities Portfolio Statement | Transactions where liquid securities may support margin, collateral, or securities-backed borrowing. | Haircut, pledgeability, custody, beneficial owner, and lender control matter. |
| Ready Willing And Able Letter | Preliminary confirmation that a buyer or applicant is prepared to proceed. | Often soft comfort only unless supported by bank verification, escrow, blocked funds, or instrument issuance. |
| SBLC Or Bank Guarantee | Where the beneficiary needs fallback payment protection rather than general proof. | Issuer, beneficiary, wording, expiry, draw conditions, rules, and bank acceptance control value. |
| Documentary Letter Of Credit | Where a seller wants payment against compliant shipment or delivery documents. | Document set, UCP 600 wording, shipment timeline, presentation path, and issuing bank risk matter. |
How A Proper Bank-To-Bank Verification Process Works
The process should start with the commercial reason for verification. A request for MT799, MT199, BCL, POF, escrow, blocked funds, or SBLC support should be tied to a real transaction, not a random document hunt. Banks are more likely to cooperate when the purpose, parties, amount, wording, and compliance file are clear.
- Define the transaction. Identify the buyer, seller, applicant, beneficiary, amount, currency, closing timeline, goods or assets, and reason proof is needed.
- Confirm the recipient’s requirement. Ask whether the counterparty wants MT799, MT199, a bank letter, escrow proof, blocked funds, SBLC, DLC, or another format.
- Review bank policy. The sending bank must be willing and able to issue the requested communication or document.
- Draft the wording. Wording should state the commercial purpose, amount, parties, transaction reference, and limitation of the bank’s statement.
- Complete KYC and KYT. The bank or arranger reviews the parties, source of funds, beneficial ownership, transaction purpose, sanctions profile, and payment route.
- Transmit or issue the proof. The document may be issued as a bank letter, MT799, MT199, escrow confirmation, blocked funds letter, or operative instrument.
- Recipient verifies directly. The receiving bank or counterparty confirms authenticity through bank-to-bank channels, direct verification, or agreed escrow or custodial procedures.
- Move to the next instrument if needed. If proof is accepted, the transaction may proceed to SBLC issuance, documentary credit issuance, purchase contract signing, escrow closing, or funding.
KYC, KYT And Source Of Funds Review
Funds verification without compliance review is weak. Banks and credible counterparties want to know who owns the funds, where they came from, whether the transaction is lawful, whether the parties are sanctioned, and whether the requested proof matches a legitimate commercial purpose.
KYC reviews the client. KYT reviews the transaction. In trade finance, KYT covers the buyer, seller, goods, route, vessel, warehouse, inspection, title transfer, payment instrument, bank route, and repayment path. In acquisitions, KYT covers the target company, purchase agreement, seller, buyer, source of funds, closing mechanics, escrow, and legal authority. In SBLC or DLC transactions, KYT covers the applicant, beneficiary, issuer, wording, margin, collateral, draw conditions, and use of proceeds.
KYC Review
Company documents, beneficial ownership, directors, passports, proof of address, bank statements, sanctions screening, and source-of-funds evidence.
KYT Review
Transaction contracts, counterparty chain, goods or assets, payment route, bank instrument requirement, closing timeline, and commercial purpose.
Wording Review
Amount, currency, date, account holder, bank responsibility, transaction reference, permitted recipient, limitations, and verification method.
Verification Route
Bank-to-bank SWIFT, direct bank letter, escrow confirmation, custodian letter, secure portal, attorney confirmation, or receiving bank verification.
Common Red Flags In Funds Verification Requests
The proof of funds market attracts low-quality requests because many parties confuse verification with financing, payment, or guarantee issuance. A real bank will not send arbitrary wording to unknown parties for an unclear transaction. A receiving bank will not rely on a vague document if it cannot verify the sender, client authority, amount, and purpose.
Commercial warning: MT799 is often misused by brokers who treat it as a tradable product. It is a communication format. The value comes from the sending bank, wording, account holder, source of funds, transaction purpose, and receiving bank acceptance.
- The requested wording says “irrevocable payment guarantee” when the bank only agreed to a proof letter.
- The counterparty demands MT799 but cannot explain what the receiving bank needs to verify.
- The buyer wants proof without providing KYC, source of funds, or transaction documents.
- The seller refuses to identify its receiving bank or beneficiary requirements.
- The request involves commodity broker chains with no direct buyer, no direct seller, and no clear payment path.
- The document is a screenshot, unsigned PDF, unverifiable letter, or template with no bank contact route.
- The applicant asks for MT799 as a substitute for cash margin, an SBLC, DLC, or escrow.
- The funds are claimed to exist but cannot be tied to an account holder, custodian, escrow agent, or bank relationship.
When MT799 Is Appropriate
MT799 can be appropriate when the parties need authenticated bank-to-bank communication before a binding instrument is issued. Examples include pre-advice before an SBLC, readiness before an MT760, confirmation of bank capability before a documentary credit, transaction coordination between receiving and sending banks, or proof-related messaging where both banks accept the format.
MT799 is less useful when the counterparty needs actual payment security. In those cases, the parties should consider an SBLC, bank guarantee, documentary letter of credit, escrow, blocked funds, or confirmed payment undertaking.

FAQ: Bank-To-Bank Funds Verification
What is bank-to-bank funds verification?
Bank-to-bank funds verification is a process where one bank communicates with another bank, or provides bank-issued documentation, to confirm a client’s financial capacity, account status, available funds, readiness, credit line, blocked funds, or transaction-specific financial standing.
What is MT799 used for in proof of funds?
MT799 is used for authenticated bank-to-bank free-format communication. In proof of funds contexts, it may communicate readiness, financial capacity, account capability, transaction intent, or pre-advice before an operative instrument is issued. It does not transfer funds.
Does MT799 guarantee payment?
No. MT799 is a communication message. It does not guarantee payment, move funds, or create an operative standby letter of credit by itself. Payment security usually requires an SBLC, bank guarantee, documentary credit, escrow, blocked funds, or direct payment structure.
What is the difference between MT799 and MT760?
MT799 is a free-format bank communication message. MT760 is used for standby letters of credit and bank guarantees. MT799 may support pre-advice or readiness communication, while MT760 is tied to an operative bank undertaking when properly issued.
What is the difference between MT799 and MT199?
Both can be used for free-format bank communication, but they sit in different SWIFT message categories and are used according to bank policy and transaction context. MT799 is common in trade finance and standby-related communication. MT199 may also support authenticated commercial communication where accepted by the banks.
What are alternatives to MT799 for funds verification?
Alternatives include proof of funds letters, bank comfort letters, bank confirmation letters, blocked funds letters, escrow confirmations, custodial account letters, securities portfolio statements, ready willing and able letters, SBLCs, bank guarantees, and documentary letters of credit.
Can a bank refuse to send MT799?
Yes. Banks may refuse to send MT799 messages for proof of funds, especially if the wording is unclear, the transaction is weak, the recipient is not acceptable, the client has not passed internal checks, or the message creates legal or compliance concerns.
What documents are needed to request bank-to-bank verification?
Typical documents include company KYC, beneficial ownership details, source-of-funds evidence, bank statements, transaction contract, counterparty details, requested wording, amount, currency, purpose, receiving bank details, and any escrow, SBLC, DLC, or purchase documentation.
Is a bank comfort letter the same as proof of funds?
No. A bank comfort letter may confirm financial standing, banking relationship, or credit capability. Proof of funds is more specific and should confirm available funds or assets. The exact value depends on the wording, issuing bank, date, amount, and verification method.
