This is more of a go out with a whimper rather than a bang type thing. Being the world reserve currency (as well as the largest consumer market in the world) previously enabled the US to do things like relatively easily export inflation in spite of relatively reckless monetary policy. Now that inflation is sticking around far more persistently, even long term bonds have gone from 1-2% to 4%+, and so on. Stagflation is a conceivable longer term outcome.
The replacement will probably be a multinational currency with strictly controlled quantity tied to some sort of physical asset(s). Basically Bretton Woods 2.0, except with the learned experience of not just granting a single country immense power and having them pinky swear not to default on their obligations and then abuse that granted power. China's probably betting that that asset will be gold.
