It says: "BlackRock, HSBC among largest buyers of Evergrande debt"

Those are relatively recent purchases and they were tiny re BlackRock -

"BlackRock added 31.3 million notes of Evergrande's debt between January and August 2021, pushing its stake in the company to 1% of the assets in its $1.7 billion Asian High Yield Bond Fund, according to Morningstar."

1% of $1.7 billion, or $17 million.

That's equal to 1/100th of 1% of BlackRock's assets. And they've got $9+ trillion under management.

BlackRock has taken a hit on their equity in Evergrande, which is already largely toast:

"The data also shows that BlackRock, the world’s largest asset manager, has suffered a $95.3m book loss on its Evergrande holding, which at the start of the year stood at just over $111m."

The Financial Times in late September estimated BlackRock's total exposure to Evergrande at $400 million. At their scale they can take a $250-$400 million loss and shrug it off. Evergrande represents a several hundred billion dollar problem for China domestically, and that's before you get to the cascade risk for their property market (which represents 65-70% of all household assets in China).
