So I just put it in 5 USTs (yielding 1.4% or so) and BZF (Brazilian Real ETF, pays 10% a year. A lot of my costs are in real) and that's it
Is there a particular reason you prefer BZF to the CME futures (http://www.cmegroup.com/trading/fx/emerging-market/brazilian-real.html) ?
It's funny, IBKR allows trading of RUB,

but BRL is not provided, even though the latter is a more stable currency.
