Larry Fink, the man who oversees roughly $11 trillion in assets at BlackRock, has a message for the roughly 40% of Americans who keep their money out of capital markets: you’re doing it wrong.

Speaking at the Milken Institute Global Conference on May 5, Fink called keeping money in a bank account “one of the worst financial decisions of a lifetime.” Coming from someone whose entire business model depends on people investing rather than saving, the statement carries an obvious asterisk. But the underlying math is harder to dismiss.

The case against cash

Fink’s argument isn’t particularly new, but he’s making it with sharper language than usual. Wages alone, he told the audience, don’t guarantee meaningful participation in economic growth. The only way most people can ride the wave of an expanding economy, particularly one being reshaped by artificial intelligence, is to have skin in the game through investments.

He reinforced this theme in his 2026 Annual Chairman’s Letter to Investors, where he highlighted that roughly 40% of Americans have zero exposure to capital markets. That’s not a rounding error. That’s nearly half the country watching economic growth happen to other people.
