Global DXY - end of downtrend?!

As you can see on the chart for 60 years, the US dollar has been downtrending, but since 2014 the index has come out from under the downtrend line, during the same time the US Federal Reserve interest rate fell from 18% to zero (and now they promise to raise it) What is it, a false breakdown or really from by raising the interest rate Mr. Dollar will start to rise in price until it reaches the level of 110-120?
