Currency-hedged ETFs are designed to protect investors from currency risk. They are a simple, cheap and effective way for small investors to access currency management techniques that were once the preserve of major financial institutions.
Currency risk affects you negatively when your home currency strengthens against a foreign currency – reducing the value of your assets held in that foreign currency. That means UK based investors are exposed to currency risk on all non-hedged ETFs that trade in overseas securities.
Currency-hedged ETFs are useful because they remove the uncertainty of exchange rate fluctuations. They sterilise your portfolio against the effect of currency so that your overseas investment doesn’t gain when the pound falls or lose when the pound rises.
