> alternative payment systems enables take it or leave it deals in medium/long term.

Assuming of course that the lender is interested in the alternative payment currency. Or that the borrower is willing to accept the consequences of default.

I don’t see accepting other forms of currency to be relevant in the short term—there is little use for the Yuan outside of China, for example. I suppose creditors can use them to buy more trinkets, or trade for dollars with people who want more trinkets.

And defaults can happen at any time, but the credit rating system is still widely respected.

Things can certainly change, but I doubt overnight.

> It's why PRC is now using their 3T USD surplus to basically do their own shadow USD lending without IMF conditionalities... countries now don't need to buy USD from US.

So they’re using US dollars, not Yuan.

That trend is changing; before 2021, most of China’s loans were in USD. After COVID, loans denominated in RMB have grown to 20%.

Again, I can see how that would change conditions in the long term, but not overnight.

I am not optimistic for the dollar in the long term but I used to fear waking up one morning to hyperinflation. Not anymore.

Yes, hence "medium/long term", though for me that's potential 10-20 year horizon.

> buy more trinkets

RMB buys capita goods, energy goods... and as PRC domestically moves way from oil, it still has massive refining/petchem infra generating surplus, so they'll likely be net hydrocarbon seller (refined products), as in RMB can even buy oil / oil products. This part important, 2025 PRC has parity/exceeded the US as worlds largest crude refiner by capacity. Together with massive, massive SPR for storage... aka they have like 1B+ barrels of oil in storage which gives them pricing power (as in they have artifical oil field to influences oil prices). They will not be retiring all the oil infra as they electrify, they'll use freed up surplus for reselling hydrocarbon in rmb. Right now, outside of high end commercial aviation and semi conductor, PRC can underwrite 99% of development goods for affordable prices. This not 10/20 years ago where countries still had to through host of western industries to get factory/city off ground, PRC more or less one stop shop now. The TLDR is rmb buys entire physical layer that enables modernity.

> credit rating system is still widely respected.

Respecting western credit rating =/= fear of being locked western credit rating. People don't default from eurodollar because they fear losing access to energy, food, commodities. Things already changed in the sense RU has demonstrated BRICS makes surviving outside of western finance system feasible. Fear is what enforces/maintains system. Respecting is about keeping options open not avoiding death sentence anymore.

>US dollars, not Yuan.

They're doing both, refinancing or inking new contracts in RMB. But main point is PRC shadow dollar lending is part of their dedollarization effort = getting rid of / recycling / lending their surplus USD at expense of US treasury. People may keep using USD, but US gov not getting exorbitant privilege. As long as USD is being used, and as long as PRC can maintain trade surplus, PRC can feasibly maintain pool of USD to ensure USD liquidity remains costly. It's like the oil/SPR reserve, PRC having pool of USD to reprocess/recycle gives them some pricing power to undermine oil/and USD.

>hyperinflation

IMO this more likely than not, and not really something to fear. Not end of society hyperinflation but if US debt gets too unsustainable, geopolitically much better to inflate away debt and fuck creditors than default. Like it's still reputationally technical/soft default, but less "embarassing", and more importantly, because dedollarization takes time, mechanically US can inflate debt faster than holders can ditch USD without crashing value. If things get desperate to that point, USD has the dollar is our currency but your problem nuclear option. Not saying this good for US, but least bad for US.
