How does SWIFT realistically know how widely used is the Yuan when the Yuan's usage is not captured by going through the SWIFT system? Not counted does not mean not existing. That is already an open indication of how propaganda works.
The whole idea behind the de-dollarization motive of BRICS was and is to not let SWIFT capture and control the trade deals done outside the US$. It is true that China is now demanding that Chinese exports to the USA be settled in gold, silver or Yuan, the USA can keep pretending that de-dollarization is just an irritant, that is until the shit hits the fan.
How realistic are USA and Western intelligence when China blindsided them in the EV sector as an example? These Western and Japanese carmakers have presence in China yet were basically sleepwalking while Chinese EV makers were eating their breakfast, lunch and dinner.
It is the arrogant mindset of the West that China cannot overtake them in any sector which is going to be the downfall of the West. Even Elon Musk, a decade earlier had laughed at the mention of Chinese EVs, brushing them aside as minor irritants at best. Today, Elon is not laughing anymore and is instead worrying about Tesla losing market share to BYD. Tesla sales had been propped up by subsidies inside the USA market, but after the split with Trump, those subsidies are now gone, together with the sales advantage.
And the irony of the arrogance mindset is extended to behavior of ASML, boasting that the Chinese will not be able to make a lithography machine even if ASML gives them the blueprints. How arrogant was that? I think ASML is regretting its arrogance already and eating its words with the progress that Huawei and SIMC are making in the chip-making hardware business. Remember that ASML still depends largely on Chinese rare earth elements and should not be boasting too arrogantly when its existence is at stake. Again, people in glass houses should not throw stones thinking they are immune. Their glass house will crash down when others retaliate.
