Speaker explicitly said "stay long the Greenback," calling the USD "the only high-quality hedge." The US has stronger growth indicators than Europe/Asia, offers high-quality carry, and is more insulated from the energy shock. The dollar is also needed to fund a global liquidity crunch for dollar-priced oil. LONG as the USD combines defensive hedging properties with positive carry and relative economic strength in a risky macro environment. The Fed turns decisively dovish while other central banks hike, undermining the rate and growth differentials.
The dollar is strengthening as yields rise and global growth concerns mount. The U.S. is energy independent relative to Europe/Asia. An energy shock hurts net-importers (Europe/Japan) more than the U.S., widening the growth differential. Higher U.S. yields attract capital to the USD. LONG USD. Specifically against low-yielders like EUR or currencies exposed to trade shocks. Coordinated central bank intervention to weaken the dollar.
