FYI: Currency hedging mitigates the additional volatility that exchange rates impose on foreign assets. But these currency-hedged strategies bear additional costs and can have tax implications. Our recent research paper, "The Currency-Hedging Dilemma,"addresses these various considerations. It reviews the fundamentals of currency hedging, explores the extra costs, and outlines a framework that investors can use to aid in their decision to choose a currency hedged fund.
