With currency options trading mostly over the counter and outside public exchanges, one way to trade options with FX rates exposure is currency ETF options.
There are optionable ETFs on major currencies by Invesco CurrencyShares, with all their symbols starting with "FX". However, their options are very illiquid, typically trading low hundreds of option contracts or less per day.
The currency ETF with most liquid options is UUP, which tracks the US dollar index - a weighted geometric mean of the USD rate against a basket of major currencies. EUR has by far the greatest share at 57.6%, followed by JPY, GBP, CAD, SEK, and CHF.
