California State Teachers’ Retirement System (CalSTRS) is to consider investing in infrastructure debt as part of its $10.9bn (€9.2bn) “inflation sensitive� portfolio.

In an investment committee report, the $307bn pension fund said “the team will explore and evaluate the merits of establishing an infrastructure debt strategy�, citing the potential for “portfolio diversification and attractive risk-adjusted returns and cash yield�.

CalSTRS has been expanding its infrastructure equity portfolio in recent years, which is expected to make up between 65% and 70% of inflation-sensitive portfolio over the coming 12 months, but it has yet to invest in infrastructure debt.

In a report for its investment committee this week, CalSTRS said it expects the inflation-sensitive portfolio to rise from 4% to 6% of total assets by 2023, and the expansion would “focus on infrastructure investments�.

Infrastructure assets held by the pension fund are expected to rise by $1.5bn over the coming fiscal year.

“The team was very busy in the infrastructure market during the past year and we continue to expect there to be a growing number of opportunities both in the US, Asia and Europe,� it said.

CalSTRS will also monitor opportunities in emerging markets.

The pension fund said it would also increase its exposure to renewables, which make up part of its $1.58bn sub-portfolio of low-carbon investments, but only where the risk-return metrics were justified.

“However, we are very much aware of the heated competition for many of these assets and have walked away from assets that we believe are overpriced,� it said.

As for the pension fund’s larger $37.2bn real estate portfolio, which represents around 12% of total assets, CalSTRS said it would focus on assets that can provide “durable income�, including multifamily, industrial, and specialist property types, together with private debt investments.

It will also pursue “develop-to-core� strategies in the industrial, life-sciences and certain residential sectors, and “seek out opportunities to take advantage of the dislocation cause by COVID and the pending economic recovery�.

CalSTRS also plans to expand its use of “highly controlled joint ventures� and strategic investments in real estate operating companies.

“Expanding these highly aligned structures will generate higher returns through improved deal flow and fee savings,� it said.
