Typically this sort of stuff is the tip of the iceberg, especially in places where bad news that makes leaders look like idiots are suppressed. I wouldn't be surprised if this was the sort of 2007 event that got 2008 rolling.

Aside from potentially rawdogging a massive economic meltdown based on extremely shaky loans, market speculation and corruption, building a lot of half built buildings is also terrible for the environment now that they are occupying lands that used to be habitat. Some people probably bought places that will also never be finished, now.

You can no longer dump your worthless stock.

meteor means things high in the sky. from Greek ta meteōra "the celestial phenomena, things in heaven above," plural of meteōron, literally "thing high up,"

if they considered "ejecta" rising after the metorite crashes and sends material into space.

Mostly likely yes (insofar as a single bank can matter). When banks collapse it sets off a cascade of debt defaults which rapidly contracts the real money supply in an economy, since most actual wealth (and, in turn, the physical creation and transfer of goods, services, and labor that facilitates) is created via fractional reserve lending. This causes a recession. If it was only this bank, it probably wouldn't be that huge of a deal for China more broadly. But it's not only this bank, and it is a huge number of provincial pet banks all tied to the same development and speculation industry. There's a reason economists have been sounding alarm bells. That's not to say China doesn't have the resources to deal with this and/or the fallout, but it is at least a problem to be dealt with.

Trading in Evergreen was closed already 1½ year ago, when the company entered liquidation.
So the delisting was inevitable and is not really significant.

Hong Kong High Court ordered the company to be wound up in January 2024.
Evergrande's shares had been under threat of delisting ever since because they were suspended from trading after the court order.

Wound up means liquidation.

But yes people and banks have absolutely lost money on this, but the ripple effect started already before the liquidation, it's been going on for at least 2 years now.
But for a country of 1.3 billion people, $45 billion is only $35 per capita, so not something that will likely destroy an economy as big as Chinas.

It's been pretty much party line that they want this to happen for some time now. Pooh bear famously made this houses are for living in speech and directly wanted to knock out speculation. They do not want to be the West and define themselves by asset prices rising with no relationship to productivity. What the West would view as a major crisis then is the CCP's intended effect. They specifically targeted these highly leveraged developers with the theory (correct in my opinion) that the loans themselves are what are driving this "growth" and it's largely creating a situation of extraction that's pricing out regular Chinese from housing. Even making noises in that direction would seriously spook Western housing prices. Harris's solution was famously increasing lending if you remember.

Here's the thing, they can sweep this one under the rug but this is just a symptom. There will be more.
