Why the Dollar Was Key to the 1st Half

As Russ explains the key to asset returns in the first half of 2018 was the dollar, not interest rates.

Like most years since the most recent financial crisis, investors began 2018 with one big question: Is this the year interest rates finally rise? After several years of anticipation, this year the answer turned out to be yes. Short-term rates rose as the Federal Reserve (Fed) stuck to their script of gradual tightening, while U.S. 10-year Treasury yields rose above 3% for the first time in over four years.

Still, despite the fulfillment of this long-held prophecy, rates have not dominated markets. Instead, it has been the byproduct of higher U.S. rates that has been most impactful: a resurgent U.S. dollar. To understand the markets in the first half of 2018, and to have a chance of navigating them successfully in the back-half, investors need to focus on the dollar.

During the first six months of the year, the best performing asset or sub-asset classes were those that either benefited directly from a strong dollar, such as U.S. consumer discretionary stocks, or those that are perceived as relatively resilient to a strong dollar, like U.S. small caps. As for the laggards, they tended to have one thing in common: a negative beta or sensitivity to a strong dollar. Examples include Chinese equities, broader emerging market (EM) stocks, EM debt and gold (see Chart 1).


Emerging market equities are probably the best example of an asset class that rose and eventually fell with the dollar. From mid-December of last year through the January peak, EM stocks rose roughly 15% in dollar terms. Even after surrendering much of those gains, as late as March EM stocks were still up for the year. Then everything abruptly changed. The dollar surged over 7%; EM stocks lost approximately 13%.

Despite the potential export benefits that some EM stocks receive from a strengthening USD, investors in locally denominated EM assets suffer FX losses during periods of dollar strength. In addition, many EM companies borrow money in USD; when it strengthens, the real economic cost of their balance sheet liabilities increase. Recent losses in emerging markets are completely consistent with previous bouts of dollar strength. During the past eight years, monthly changes in the DXY have explained approximately 30% of the variation in emerging market equity returns. For every 1% increase in the value of the dollar, EM equities have typically lost about 1.15%.
