BlackRock’s CEO Larry Fink may now be the most powerful man in the world, overseeing not just the Fed’s new (potentially $4.5 trillion) corporate slush-fund, but also managing $27 trillion of the global economy (even before the March appointment). As the world’s largest asset manager, BlackRock already was managing $7 trillion for its global corporate investor-clients, along with another $20 trillion for clients through its financial risk-monitoring software (called Aladdin).
