What is wire transfer?

A wire transfer is a real time, credit push transfer of funds between banks that settles with finality, meaning it cannot be unilaterally reversed once the receiving bank accepts it.

Also called Fedwire · CHIPS · funds transfer

Domestic United States wires move over Fedwire, operated by the Federal Reserve, or CHIPS, a private clearing house. Both are designed for high value, time critical payments and both settle with finality. Finality is the property that makes wires useful for closings and payroll funding, and the same property that makes wire fraud so damaging.

Recovery after a fraudulent wire is not a reversal. It is a request to the receiving institution to freeze funds that have not yet been withdrawn, often coordinated through the FBI IC3 Recovery Asset Team. The window is measured in hours.

Liability does not follow intuition either. Under UCC Article 4A a payment order the customer authorised, or one accepted under a commercially reasonable security procedure the customer agreed to, generally stays with the customer. Consumer protections such as Regulation E do not extend to a business wire. That is why the practical protection sits in the release process rather than in the aftermath.

In fraud the wire is rarely the first event. The instruction arrives as a change of remittance details, a new account for an existing supplier, or an urgent closing amendment, and it arrives through a channel the attacker already reads. By the time the payment is keyed, the deception has already happened upstream, so the only durable control is binding the payee to the account before release.

Common questions

Not unilaterally. Once settled, the funds belong to the beneficiary, so recovery depends on the receiving bank voluntarily freezing or returning them before they are moved.

Hours, in practice. Reporting immediately to the originating bank and to the FBI IC3 gives the best chance of a freeze at the receiving institution.

Usually the business. Under UCC Article 4A a payment order the customer authorised, or one accepted under an agreed commercially reasonable security procedure, generally remains the customer's loss, and Regulation E consumer protections do not apply to business wires.

A wire settles individually and with finality, usually the same day. ACH settles in batches and has defined return windows, so an ACH credit has limited return paths that a wire does not.

Call the originating bank and ask for a recall to the receiving institution, file with the FBI IC3 so the Recovery Asset Team can engage, preserve the original instruction and mail headers, and check whether other pending payments used the same account details.
