The 10-year U.S. Treasury yield hit a recent high of 1.56% last week as key inflation data showed consumer prices spiking to multi-year highs in the U.S. and the euro zone.
While consensus among central bank policymakers remains that higher inflation is transitory, the result of a confluence of surging energy prices and global supply problems, investors have begun to seek protection, with major stock markets snapping multi-month winning streaks in September.
The return of a regime of higher and less stable inflation across major economies would cause a spike in exchange rate volatility, and ultimately the depreciation of currencies in countries experiencing the highest inflation prints, according to Jonas Goltermann, senior markets economist at Capital Economics.
"Although the near-term relationship between inflation differentials and exchange rates is weak, over longer time horizons countries with relatively high inflation tend to experience depreciation of their nominal exchange rates," Goltermann highlighted in a research note last week.
"Indeed, on a long enough period, this effect often dominates other factors affecting exchange rates, such as relative productivity and terms of trade."

Goltermann noted that in general, nominal exchange rates weakened over that period in countries with higher inflation, but when central banks tightened pol...
