The Cost-Revenue Gap Redefining Asset Management

August 20, 2026

For over a decade, rising markets followed by rising AuM has been the industry’s growth story. That formula is breaking down.

Average management fees have fallen 23% since 2010. Costs have outpaced revenues for 15 consecutive years, a persistent 34bps gap between cost and revenue growth.

Scale alone no longer protects margins. Firms that close this gap deliberately, rather than relying solely on AuM growth, stand to unlock meaningful value – the difference between being a 30% margin business and an industry leading 50%+.
