Vanguard, the world’s second-largest ETF issuer, recently announced its largest fee cuts in its 50-year history. The company has reduced fees

Vanguard Group Inc., the world's second-largest ETF issuer, is making what it says is its biggest fee cuts in the company's 50-year history, trimming the expense ratios of dozens of mutual fund and ETF share classes that it claims will save investors more than $350 million in 2025.

As one of the world’s largest asset managers, Vanguard’s move will pass on significant savings to investors while also putting significant margin pressure on ETF competitors. However, the implications for the ETF industry will vary by ETF category.
