an agreement to exchange two currencies is called a(n)
Currency swap [1][2]A cross-currency swap's (XCS's) effective description is a derivative contract, agreed between two counterparties, which specifies the nature of an exchange of payments benchmarked against two interest rate indexes denominated in two different currencies. It also specifies an initial exchange of notional currency in each different currency and the terms of that repayment of notional currency over the life of the swap.
New Zealand dollar The New Zealand dollar (sign: $; code: NZD, also abbreviated NZ$) (Māori: Tāra o Aotearoa) is the official currency and legal tender of New Zealand, the Cook Islands, Niue, the Ross Dependency, Tokelau, and a British territory, the Pitcairn Islands.[1] Within New Zealand, it is almost always abbreviated with the dollar sign ($), with "NZ$" sometimes used to distinguish it from other dollar-denominated currencies. In the context of currency trading, it is often informally called the "Kiwi" or "Kiwi dollar",[2] since New Zealand is commonly associated with the indigenous bird and the one-dollar coin depicts a kiwi.
