After the US currencies rapid rise as an alternative to weaker global currencies the cycle is about to change as US continues to see low economic readings and political pressure mounts. The low numbers in the US mean that for now the risk of higher brought on by a weak dollar is an acceptable risk to protect businesses and avoid tantrums in the White House. US 10 year yields are going through the floor. Investors have already started pulling funds out of the USD.
This unusual situation has been brought about by donald trump's weaponization of trade tariffs and has only served to isolate the USA in the commercial world.
China is no free to allow the market to dictate the slide of the Yuan and make Chinese imports into the USA competitive regardless of trump's attitude.
USA has only two options: 1) Negotiate a compromise with China, or 2) reduce it's own interest rates to devalue the USD thereby making Chinese import more expensive and making it's own export cheaper.
the dollar will continue the slide regardless.
