Powell has pretty much the same mindset as Yellen, so things should continue along the same course at the Fed. March will almost certainly see a rate increase, and right now odds are we'll see three increases in 2018, which would get us to 2.25%.
However, there are signs of wage inflation, and that could force the Fed to begin raising rates more aggressively. I also think Europe will be surprised by an unexpected uptick in infaltion, forcing the ECB to move faster than they would like. And then there's Japan with its negative interest rate policy - crazy.
And underpinning all of this is the race to the bottom for currencies. It's been very surprising to see the USD tanking even as the U.S. is one of the few major economies raising interest rates. Shit is looking wonky, and then we also have the very old bull market in equities - not to mention the uptick in commodities pricing.
2018 could be quite a turbulent year, especially considering how low volatility has been in the markets. The normal investor isn't used to or prepared for normal market volatility.
