US/World divergence about 15%

We face a clear 15% world divergece between US an the rest of the World markets.

So the main question is, which central bank can injekt most in the world?


US?
China?
Europe?


China is the biggest creditor to US state deficit.

So the US Economy gain runns on China credit to buy China goods.


Trading,

in fact we easy can move down 10% without any problems.
In case of China corona i face, that we are a litte overbought in
the US.


Ideas?
