The climbing higher dollar since June 2014 has started to kill big parts of the economy. The same parts, higher commodity prices, that helped the so called recovery. Energy, mining, farming etc.
The lower rates only helped retail, houses, and cars and consumers too with lower energy costs.
So the Fed may be raising rates now so they can lower them for stimulation later on as things get worse. Worse? Could mean commodities get so low, producers go out of business, and supplies and shortages start happening.
