If I invest in securities denominated in a foreign currency, should I hedge my currency risk?
So far we have a case for yes and no.  I believe the correct answer is... maybe. You mention that most of your expenses are in dollars which is definitely correct, but there is an important complication that I will try to simplify greatly here.  Many of the goods you buy are priced on the international market (a good example is oil) or are made from combinations of these goods.  When the dollar is strong the price of oil is low but when the dollar is weak the price of oil is high. However, when you buy stuff like services (think a back massage) then you pay the person in dollars and the person you are paying just wants dollars so the strength of the dollar doesn't really matter. Most people's expenses are a mix of things that are priced internationally and locally with a bias toward local expenses.  If they also have a mix of investments some of which are international and depend on the strength of the dollar and some are domestic and do not, then they don't have to worry much about the strength/weakness of the dollar later when they sell their investments and buy what they want.  If the dollar is weak than the international goods will be more expensive, but at the same time international part of their portfolio will be worth more. If you plan on retiring in a different country or have 100% of your investments in emerging market stocks than it is worth thinking about either currency hedging or changing your investment mix.  However, for many people a good mix of domestic and international investments covers much of the risk that their currency will weaken while offering the benefits of diversification.  The best part is you don't need to guess if the dollar will get stronger or weaker. tl;dr: If you want your portfolio to not depend on currency moves then hedge.  If you want your retirement to not depend on currency moves then have a good mix of local and unhedged international investments.
