ETF investors erring on the side of greenback strength can look to the Invesco DB US Dollar Bullish (UUP) to capture this potential momentum. UUP tracks the price movement of the U.S. dollar against a basket of currencies, including the European Union's euro, the Japanese yen, the British pound, the Canadian dollar, the Swedish krona, and the Swiss franc. Inflationary pressures in Japan could be a harbinger of what's to come for the rest of the world, which could support the case for more bullishness for the U.S. dollar.
