Gold-man seems to think more rather than less rate hikes by 2019:
"In order to ensure it achieves the growth slowdown we think is needed to contain overheating risks, the Fed will likely still need to deliver significantly more hikes than embedded in current market pricing. As a result, we remain comfortable with our call for 5 more hikes—2 more than priced—through the end of 2019."
