Can US interest rate hikes go on till 2020?

CONTRARY to recent expectations for rate hikes till middle of next year, the Fed has signalled for increases until 2020.

Its projections are made based on expected strong growth in the US for three more years. Would the pace of rate hikes have to slow down sooner, as earnings, boosted by tax cuts this year, get normalised and higher interest costs pose downside risks to earnings, employment and consumer spending?
