‘兑汇’ (duì huì) is a formal financial term meaning ‘foreign exchange transaction’ — the act of exchanging one currency for another, typically at a bank or authorized FX service. The character 兑 (duì) originally means ‘to exchange’ or ‘to redeem’, and 汇 (huì) means ‘to gather’ or ‘to remit’, often used in financial contexts like ‘remittance’ or ‘exchange’. Together, they form a compound noun emphasizing the conversion process between currencies.

This term appears primarily in banking, finance, and official documents — not in everyday casual speech. It’s commonly used in phrases like ‘兑汇业务’ (FX services), ‘兑汇额度’ (FX quota), or ‘办理兑汇’ (to conduct an FX transaction). While similar to ‘换汇’ (huàn huì), ‘兑汇’ carries a more institutional, procedural connotation — implying authorized, regulated exchange rather than informal swapping.
