There is no way these moves can be natural market forces. The global economy master planners made a sudden panic adjustment. Their past MO has been to fight deflation in wages and some other things, and get spending money into people’s pockets any way possible.
The only possible logical angles that comes to mind are….
#1 Cheaper gasoline and cheaper heating oil, and cheaper diesel fuel in the USA are net big pay raises.
#2 The foreign currencies that DROP inverse the dollar helps those countries gain some sorely needed inflation, and helps the exporting businesses to export.
#3 If these are natural market forces, then we can figure prior over production cause by very high prices $140 oil etc. or…
#4 The global economy is imploding or transitioning to more separatist independence trends.
