Little knowledge here about Blackrock. I only got interested when I heard the name entering BTC ETF. I was surprised after learning that sovereign wealth funds, pension funds, big businesses (GE, IBM, and Microsoft), and insurance firms trusted this company with their funds. Central banks (BOE, ECB, and BOJ) are part of its clients. Moreover, the company is also "responsible for managing universities like Stanford University and Harvard University as well as charitable organizations like the Bill and Melinda Gates Foundation."

I wonder what would be the impact on those funds and clients and the global economy as well once such an epic demise takes place.
