Option One.
They anticipate a recession sparked by a real estate and or stock market correction, and wanted room (ammo) to drop rates later.
Option two.
Just like running out to buy a house before rates go up. They could have raised the dollar so the US retailers of whatever they like to retail, could fill their inventories on the cheap before the tariffs get started.
Option three.
The Federal Reserve, manager and dictator of the so called global commune-ity is going to shove it up, or rater show Trump and the masses that voted him in, who the REAL boss is.
