What Role Can the Dollar Play in Investor Portfolios?

A Hedge against Market Uncertainty

As we have seen recently, foreign currency risk is undesirable in certain market environments. During periods of economic stress, investors flock toward stable, liquid assets when attempting to reduce their exposure to the markets. Given the U.S. dollar’s current role as the world’s reserve currency, it tends to appreciate during periods of increasing global uncertainty. When an investor buys a currency such as the dollar, he is implicitly selling short a foreign currency to gain this exposure. Given the simple laws of supply and demand, this trade has the effect of driving up the price of the dollar against the foreign currency that was sold.

Portfolio Diversification through Negative Correlation

Historically, currency returns generally have a positive correlation with local asset prices. When U.S. investors buy foreign assets such as stocks and bonds, they must convert their dollars to the local currency and purchase locally denominated assets. This causes an increase in demand for the local currency as well as a rise in asset prices. The dollar, by comparison, is seen as a “safe haven” currency in the current market environment. Therefore, as risky assets decline in value, the value of the dollar may tend to increase. This perhaps overlooked current market dynamic has the impact of creating a negative correlation for most foreign currency positions against the S&P 500.

Conclusion

Investments in the U.S. dollar against foreign currencies can be used in a variety of ways in an investor’s portfolio. Given the low opportunity costs associated with long positions in the U.S. dollar against many developed market currencies, the current role the U.S. dollar plays in the global financial system and the potential for diversification from a negatively correlated asset to traditional asset classes, we believe that certain market environments may create opportunities to benefit from a strengthening U.S. dollar.
