The $13 billion San Diego City Employees’ Retirement System is deepening its push into private debt while broadening its real estate exposure into alternative property sectors. Trustees this month approved a $25 million commitment to the TPG Twin Brook Direct Lending Fund, part of a $265 million private debt portfolio slated to rise from 2% to 5% of plan assets under the system’s long-term targets. 

Managed by TPG Twin Brook Capital Partners, the evergreen vehicle focuses on senior secured, sponsor-backed loans to lower middle-market companies, targeting $2 billion in assets with 1.25 times leverage and emphasizing first-lien loans in non-cyclical sectors. Consultant Callan told trustees the strategy complements SDCERS’ earlier allocations to upper-middle-market funds such as the Blue Owl Diversified Lending Fund and sits alongside core direct lending mandates with Golub, Antares, Ares, KKR and Blue Owl. 

On the real estate side, consultant Meketa recommended, and trustees approved, a $35 million allocation to the Clarion Alternative Sectors Fund. Managed by Clarion Partners, the fund aims to generate cash flow and long-term value by investing in senior housing, industrial outdoor storage and build-to-rent communities, with plans to expand into alternative housing, healthcare, logistics and storage. Clarion is targeting a $1 billion initial raise and net IRRs of 9% to 10.5% over a full cycle, with roughly 50% to 60% of total return coming from income. 

Through September 2025, SDCERS posted a 9.7% annualized return, led by strong global equities and 9.2% gains from private debt, outpacing its 6.5% actuarial assumption. Real estate stands at $1.2 billion, or 9% of assets, versus an 11% target.
