In a global economy, the real return on CDs increases when the U.S. dollar appreciates relative to the currencies of our trading partners. There is nominal interest rate and there is real interest rate. Normally, real rate = nominal rate - inflation rate ; however an appreciating currency can mimic a lower inflation rate. So for those on fixed income or dependent on CD yield an appreciating currency is beneficial. (Very few retirees, if any, have their entire retirement portfolio in nothing but CDs.!)
Given the present economic conditions, the Fed will most likely wait and monitor inflation, since the appreciating dollar is already doing the "heavy lifting" for them, so to speak. They don't have to raise interest rates right now.
The U.S. has primarily a consumer driven economy. Only a small percent, ~13%, is export dependent. So an appreciating currency, on balance, should be good, rather than bad, for the economy. This effect will be bolstered by low crude prices, which are expected to remain low for a considerable period.
