Have you noticed that in the central banking world there is no difference in action between supposed communist or supposed capitalism regimes? Constant bail outs, constant intervention, the only variable being the degree of intervention at any given time, for whatever reason.
How is the PBOC doing anything different than the US Fed? Cut rates, repo, liquidity injections, it’s all the same script. The BOJ buys ETFs, the SNB buys US FAAMNG stocks, all is centered and focused and organized to prevent any market damage.
