There is so much. If you start from why did SOFR start in the US and go back and research it you will find out. Thats why I said do some reading. Even Google will confirm what I stated above. Read anything on the Fed website . Anything written by Tom Luongo--gold goats and guns. Anything by Alex Krainer. You need to look at world financial centre history to see the City of London world influence today . There are players with the same interests in both the US and UK that align and those that don't. The two countries are not homogenous blobs-- there are different factions in both which create lots of differences.
