Hola Enrique; the simplest way is using forward or/and future contracts if available between the currencies. If not available, there might be some Government Bonds and you could use the interest coupons.

Enrique - Short to medium term, you can do this through derivatives (forwards/futures/options) or by borrowing/lending in the currency you receive revenues or incur costs. Long term, however, the only way to hedge is operationally, as it becomes more costly to hedge + harder to forecast revenue/cost streams the longer into the future you look. That is naturally hard for a fund investing in foreign currencies (i.e. it's not like a business where you may move operations to countries you have significant revenue in). In the end, there are some things you can do at the portfolio level, but you will likely have to accept some degree of currency risk. The more currencies you invest in, the more this tend to wash out, but there is always the chance the currency you "live in" strengthens long-term compared to the currencies you have invested in.
