Currency Hedging: Aiming for Efficiency

Institutional investors: Are your currency hedging strategies efficient?

Institutional investors often hedge currency exposure in their portfolios because swings in exchange rates can easily overwhelm returns from investments, especially in today’s low-return environment. A common practice among investors is to build currency hedging strategies specific to various asset classes. Many also hedge investments at a uniform rate, either at the portfolio level or at the asset-class level.

Our research suggests it may be more efficient to make hedging decisions at the portfolio level on a currency-by-currency basis, especially for non-U.S. dollar-based investors. Hedging decisions made at the asset level ignore the relationship between currency exposure in one asset and other parts of a portfolio; imposing uniform hedge ratios at the portfolio or asset level limits one’s ability to benefit from the diverse risk/return trade-offs offered by different currencies.

In fact, our research found Australian and Japanese investors may be able to reduce tail risks (as measured by conditional value at risk (CVaR)) in a standard 60/40 portfolio by up to 1.5 percentage points and 3.0 percentage points, respectively, without sacrificing returns, relative to having a uniform hedge ratio at the portfolio or asset level.

For U.S. investors, hedging may be simpler: Our research showed the potential for no loss in efficiency even with a uniform hedge ratio. However, much depends on the investor’s return assumptions, risk model and portfolio allocations. In general, we believe that portfolio-level currency-by-currency hedging will always be optimal.

Although forecasting currency volatility and returns has always been a challenge, especially for non-U.S.-dollar-based investors, an efficient hedging strategy remains an important way to try to mitigate uncompensated risk. And in a period of low prospective returns, every basis point counts.
