Intermediary Institution

An intermediary institution is a financial institution that takes part in a funds transfer without being either the institution of the person sending the money or the institution of the person receiving it. It receives the payment instruction and funds from one institution and passes them on to the next, until the payment reaches the beneficiary institution. Intermediary institutions are common in cross-border payments, where the originating institution and the beneficiary's bank do not hold accounts with each other and must route the payment through correspondents.

The term is used in payment messaging standards, in the FATF recommendations on wire transfers and in national laws. It is close in meaning to intermediary bank, but "institution" is broader and can include non-bank payment providers. An intermediary is often also a correspondent institution for one of the other parties.

A cross-border payment typically involves four types of party: the ordering customer who sends the money, the originating institution, one or more intermediary institutions and the beneficiary institution, which credits the beneficiary customer. For example, a business in Germany paying a supplier in Thailand in US dollars may send the payment through its bank, which instructs its US dollar correspondent in New York. That correspondent pays the Thai bank's correspondent, which credits the Thai bank. The two New York banks are intermediary institutions.

Intermediaries may perform several functions: moving funds through domestic clearing in the payment currency, converting currencies, checking and repairing payment data, screening for sanctions and passing on the payment message. Each may charge for its services, as described under intermediary bank fee.

Payment messages identify intermediaries in specific fields. In legacy SWIFT MT103 messages, field 56a names the intermediary institution, and field 57a names the account with institution, meaning the beneficiary's bank. In ISO 20022 messages such as pacs.008, up to three intermediary agents can be listed in structured elements, alongside the debtor agent and creditor agent. Senders who know the routing, for example from standard settlement instructions published by the beneficiary's bank, include the correct intermediary to avoid delays. If the intermediary is missing or wrong, the payment may be repaired, delayed or returned.

FATF Recommendation 16 sets specific duties for intermediary institutions in wire transfers. They must ensure that all originator and beneficiary information accompanying a transfer is kept with it as it passes through the chain. They must take reasonable measures, consistent with straight-through processing, to identify cross-border transfers that lack required information, and must have risk-based policies for deciding whether to execute, reject or suspend such transfers and what follow-up action to take. Where technical limits prevent information from being passed on, records must be kept. These obligations form part of the travel rule and are implemented in laws such as the EU's regulation on information accompanying transfers of funds and US recordkeeping rules.

Intermediaries process payments for customers they do not know directly, so they rely on the originating institution's due diligence while carrying out their own controls. Key controls include sanctions screening of all parties in the message, monitoring for unusual patterns across respondent banks, and investigating messages with missing or suspicious data. Intermediaries can be liable for processing payments that breach sanctions, which is why US dollar correspondents in particular apply strict screening. They also face requests for information from other banks and from authorities about payments that passed through them.

When a payment goes missing, arrives short or is credited late, the originating institution usually starts an investigation, sending enquiries along the chain to find where the payment was held, repaired or charged. Intermediaries must answer these enquiries and may be asked to return funds sent in error. Under rules such as Article 4A of the US Uniform Commercial Code, an intermediary that fails to complete a transfer may be required to refund the amount it received, and payment system rulebooks allocate responsibility for errors between participants. Clear records of each step therefore protect intermediaries as well as their customers.

Each intermediary adds time, cost and operational risk. Efforts to shorten payment chains include direct participation of more institutions in domestic payment systems, links between national instant payment systems, regional payment systems and providers that settle locally in many currencies. Tracking through SWIFT gpi makes each intermediary's role and timing visible. Despite these developments, intermediaries remain essential for many currency pairs and smaller markets, where direct relationships between banks are not economical.
