CalPERS Ignites a Historic $620B ‘Total Portfolio’ Investment Revolution
America’s largest public pension fund, the California Public Employees’ Retirement System (CalPERS), has officially initiated a groundbreaking transformation in its asset management. Effective July 1, 2026, CalPERS became the first U.S. pension fund to replace its traditional Strategic Asset Allocation (SAA) model with a pioneering Total Portfolio Approach (TPA).
Previously, the CalPERS board assigned fixed allocation targets to each asset class under the old framework. The innovative TPA model now evaluates every investment based on its contribution to the entire portfolio’s performance. This change provides the fund’s investment team with significantly greater flexibility to respond to market opportunities across asset classes in real time.
As part of this transition, CalPERS has adopted a single unified benchmark — a reference portfolio set at 75% equities and 25% bonds. This replaces the 11 separate benchmarks previously used. The fund’s assumed rate of return (discount rate) remains steady at 6.8%. Chief Investment Officer Stephen Gilmore anticipates that the new approach could add 50–60 basis points annually to returns.
“The CalPERS Board made history today,” said Investment Committee Chair David Miller. “We are the first pension fund in the United States to do this, and I believe it will give CalPERS staff the edge they need to make sound investment decisions.”
The fund’s private equity portfolio, now exceeding $119 billion, returned 21.5% for the 12 months ending March 31, 2026 — the best result among large U.S. public pension funds.
