Question

本币/辅币,用英文怎么说?

Answer 1

domestic currency（local currency）本币/fractional currency辅币
例如：
从根本上说,外汇储备的作用在于避免货币危机：当贬值趋势失控,就可以调用美元来够买本币.
At root, FX reserves exist to avert currency crises: when devaluation spirals out of control, dollars can be deployed to buy up the local currency.
fractional currency
也有说subsidiary money的,但没找到例句,只有：
美国的辅币包括一角的和五分的；辅币顾名思义就是比基本货币单位小的货币.
American divisional (fractional) coins include the dime and the nickel; fractional currency is currency in denominations less than the basic monetary unit.
