The International Fischer effect (IFE) considers nominal interest rates. When considering the U.S. relative to other countries assume the U.S. interest rates are generally above foreign interest rates. Applying IFE, what would the conclusion be regarding future strength or weakness of the dollar? Where should foreign (non- U.S.) investors invest if they believe IFE? Should U.S. investors invest in U.S. securities or foreign securities if they believe IFE?
