The USD is more likely to go higher against EUR and JPY in 2018 as a result of Trump tax cuts. While this author may be right about corporate tax cuts facilitating additional dividends and stock buybacks...which got their real boost from 10 years of central bank policies, the net effect of tax cuts will be more money pumped into the U.S. and global economy and higher GDP. The real questions are how inflationary? as well as the effect on gold prices. Indeed, the FED is even more likely to continue raising rates and reducing it's balance sheet, and may even accelerate the process.
