EM Currencies Can Boost Bond Portfolios Amid Rising Inflation
Currencies of commodity-exporting countries are particularly attractive.
This year’s inflation surge has had multiple causes: easy monetary policy from central banks, coronavirus‑related supply chain disruptions, tensions with Russia over the Nord Stream 2 gas pipeline, and the ensuing rise in energy prices. Annual consumer price index inflation in the U.S. reached 6.2% in November, which was the highest recorded value in more than 30 years (the previous high was 6.3% in 1990). Similarly, eurozone inflation has been trending up and hit a multi‑decade high of 4.9% in December.
These trends have increased the pressure on central banks to tighten monetary policy, which spells trouble for bond investors. At the same time, coronavirus‑related disruptions and uncertainty caused by inflationary trends spell trouble for economic growth. Struggling growth coupled with persistent inflation demands a creative approach to bond portfolio management.
We have previously suggested a few tools that bond investors can considering using in this environment, including holding inflation‑linked bonds, positioning farther out the sovereign yield curve (curve flatteners), allocating credit across regions, and actively managing duration. Now, we would like to add another: allocating to emerging market (EM) currencies. EM currencies, especially of those countries that export lots of commodities (such as Russia and South Africa), have tended to outperform during inflationary periods as they stand to benefit from rising commodity prices and higher growth potential in emerging markets.
Figure 1 shows historical returns of EM currencies during months with rising/falling U.S. inflation expectations and rising/falling U.S. real rates (a key barometer of U.S. economic growth expectations). EM currencies, particularly those of resource‑exporting countries, provided the highest returns during periods with rising inflation expectations and falling real rates (falling U.S. growth expectations). However, they also performed well during periods with rising inflation expectations and rising real rates. This suggests that resource‑exporting EM currencies can improve bond portfolio returns during inflationary periods irrespective of whether real rates are falling or rising.
EM Currencies Have Typically Performed Well in Inflationary Periods

Figure 2 shows the returns of EM currencies during the period since the onset of Coronavirus—a much smaller, but more recent, sample. It reveals that EM currencies performed their role well during periods with rising inflation expectations and falling growth, which spanned about half the post‑coronavirus period.
Post‑COVID Onset, Rising Real Rates Hampered EM Currency Performance

Crucially, however, it also shows that EMs did not perform as well during inflationary periods with rising real rates. This was likely a reflection of the market’s recent fears around the U.S. Federal Reserve ending the quantitative easing program and starting to hike interest rates, which, if overdone, could cause market‑wide disruptions. However, history suggests that these fears were probably overblown and do not reflect the fundamental advantage of resource‑exporting emerging markets in an inflationary environment.
One final point: Never lose sight of thoughtful portfolio construction. EM currencies tend to behave like “risk on” assets and suffer in a sharp risk‑off environment along with credit. As such, we believe they should be treated as a substitute for credit risk in portfolios—not an enhancement.
