The US economy and other countries that export fossil fuels will feel the impact over the next decade or so. The energy transition might go a lot quicker than people seem to expect. Currently about 20% of global car sales is electric. In some countries it's well over 50%. China of course being one of them. And they are making rapid progress with electrifying freight as well. This is already impacting their fossil fuel imports. They still import a lot.
One effect that I think people underestimate is that while it will take a long time for all the ICE vehicles to disappear, the new ones do most of the driving. So, new EVs have a relatively large impact on fuel consumption and imports pretty early on. E.g. Chinese diesel imports apparently already are being impacted by their rapid deployment of tens of thousands of electrical trucks. Soon hundreds of thousands. That's already a third of the market in China and will probably head for well over 50% in a few short years. The EU is not that far behind.
The ripple effect that's going to have on oil trading, refinery capacity, etc. is going to be substantial. Of course current geopolitics is speeding things up massively. LNG and oil scarcity is causing a lot of issues globally and countries are accelerating moves to reduce their dependence on that.
The euro is in a much better position to be adopted as an alternative, but its share of global reserves has been flat at around 20% for years.

while Yuan usage in trade will reduce the US influence, the amount of assets held in dollar nominated investments is so so much bigger, and this will very slowly change if it will at all.
Here is one hint. The reason why currencies like the Spanish dollar or Dutch guilder became standards were primarily questions of prestige and minting quality as you held those currencies in your own possession. But everyone could recognize a guilder and so when dealing with a foreigner, it was easier to have them.
In that type of environment, being a global export power meant that you were a global gold issuer because you sold your goods to the rest of the world, got their gold (or silver), melted it down, and issued your own stamped gold or silver coins, that circulated all over the world.
If that is your mental model of foreign trade today, then please read a bit further in your history books, because we live in the world of non-convertible fiat money. This means that when China sells $100 of stuff to America, it doesn't get to take that money home, the money is kept in an American bank account, with the name of that chinese seller as the beneficiary of the account. It's a non-convertible currency. A dollar is always a dollar, China can't melt it down and convert it to a Yuan.
So now, to be the reserve currency doesn't mean that your specialized minting tech is being stored in central banks all over the world, it means that central banks all over the world have deposit accounts in your banking system. And that can only happen by being the world's largest importer, the exact opposite of the situation in the age of the Dutch trading empire. Your entire analysis is backwards.
It seems likely that the dominance the US has enjoyed in the recent past will diminish somewhat as other blocks with larger population bases catch up on the technology and industrialization fronts, and eventually start flexing their industrial might to create peer-level militaries.
LBH PRC not dumb enough to dig itself into Triffin deindustrialization hole US has. IMO Yuan positioning itself to be better than a reserve currency, it'll be premium currency for PRC tech stack (everything do be primogem) once PRC overtake west in critical strategic goods - ultimately, whoever controls discounted society sustaining tech / commodities stack long term controls payment preference. In meantime, PRC more than fine USD continue it's decline into debt serviced casino where somehow now house net loses until US inevitably have to debase/inflate away leaving others holding bag. There's really no alternative scenario (i.e. default) for USD at this point. Downstream of that is FX re reevaluations etc, i.e. PRC nominal > US nominal is not going to take years, is not dependant on PRC vs US growth, in the end it will take a few months of FX swing outside of either party's controls.
So, yeah, it could happen to the US, slowly, over time (it already is). But nobody wakes up tomorrow and says they no longer want USD. Where are you parking the money, yuan?
But this is yet another indicator of the loss of soft power, which is much farther gone than, I'd say, 90% of Americans realize.
The supposedly smart people in the tech industry should be alarmed by the loss of soft power. A lot of tech revenue comes from overseas, but if US technology is seen to be the tool of an unreliable, belligerent, corrupt, authoritarian government, that revenue will evaporate, and it will happen faster than, for example, fundamental international finance changes. And yet these supposedly smart people have lined up behind our government.
It seems hard to say when that would change.
I also wonder how much political backing a bank needs to offer a service with the implications towards the status of an allied currency as reserve currency status - small as it may be for now.
It worked when the country wanted to be a globalist force and lead by example (albeit it was partially pretending to set an example, US exceptionalism is ingrained in US culture and politics).
It doesn't work in an anti-globalist world, especially one in which allies are bullied.
America is essentially just a debtor of last resort, that is the superpower of the dollar.
More and more it feels like a nation's kWh throughput is the new metric to track its global influence in manufacturing, industry, and financial services. In other words electric power now equates to global power.
Waiting for the dollar to collapse in the next 100 years and see what it brings to the political arena whether it's for better or worse. I am not afraid of the devil showing off its ugly face, whoever the new devil may be.
At some point china will loose the ability to keep its global currency (Yuan, should be inflating) decoupled from the domestic one (Renminbi is deflating). They have been keeping long running issues in Banking, and Relestate at bay but a global recession (and were on the cusp it seems) is going to be brutal to china.
I suspect that if (when?) that hits this will turn into another Deutsche scandal.
I don’t really see the sinophobia as relevant at this point in history, or the US dollar pride as beneficial to the world aside from its unparalleled and impressive liquidity.
Everything should be liquid and thats the project for the world in the finance sector, adding rails for major currencies is foundational infrastructure.
Reserve currencies and soft power should be antiquated concepts.
Nations will have to learn harmony a different way.
Soviet-China-Iran - Petro Yuan?
/edit for the pedantic. Russian Federation.
Pity about the USA....
