Wire transfer

A wire transfer is the heavyweight of bank payments: an electronic credit transfer settled individually, bank to bank, with same-day speed and finality once settled. The name survives from the telegraph era, when payment instructions literally travelled by wire; the modern version travels as a message between banks and settles across a high-value payment system.

Domestically, a wire is a clean product. In the United States it settles over Fedwire, the Federal Reserve’s real-time gross settlement system, in central bank money, transaction by transaction. In the United Kingdom the equivalent is CHAPS, operated by the Bank of England. Settlement takes seconds during operating hours, and the transfer is irrevocable once made. The cost, typically tens of dollars, reflects the individual processing and the finality; the contrast is ACH, which batches and nets payments for cents each but settles on a cycle.

The phrase “international wire” describes something structurally different. There is no global Fedwire. A cross-border wire is a relay: the instruction travels via messaging between banks while the money settles hop by hop through intermediary banks along a correspondent chain. Each hop adds checks, fees deducted in flight, and exposure to another cut-off. The result is the familiar cross-border experience: a “wire” that takes days, arrives short of the amount sent, and cannot say where it is mid-journey. Same word, different machine.

Irrevocability is the property that defines the product in both settings. A settled wire belongs to the recipient; recovery of a mistaken payment is a request, and its refusal is lawful. That makes wires the instrument of choice where certainty matters, real estate closings, securities settlement, interbank funding, and makes pre-release controls, confirmation of payee, and sanctions screening the load-bearing safeguards.
