There are two things that motivate the Dollar: its leading interest rate outlook (which is currently active) and its position as a liquidity-anchored safe haven (not yet in full swing). Here we have USDollar
versus two key benchmarks for these themes. The purple line is the CBOE's EURUSD volatility
measure. The orange line indicates the inverse Fed Funds futures
contract for December 2015 which is indicative of interest rate expectations through the end of the year.
