Lower expected returns create a math problem. Private foundations, for example, must pay out about 5% of assets each year. Add operating costs, and the hurdle rate climbs. “If you don't earn returns of 8% the model doesn't work,” said Carlos Rangel of the W.K. Kellogg Foundation, one of the largest U.S. philanthropic foundations in the U.S.
That pressure is pushing investment teams to search further afield. Lew said generating outperformance may require going “a little bit further on the risk curve” and exploring strategies they have not used before.
That search has, in some cases, led endowments into cryptocurrency markets, which were once viewed as too volatile or operationally complex for traditional institutions. Early university investors such as Yale and Harvard backed crypto-focused venture funds years ago, gaining indirect exposure to digital assets through private vehicles. More recently, the approval of spot bitcoin BTC$66,923.39 and ether (ETH) exchange-traded funds in the U.S. has offered a simpler route.
Harvard University and Brown University, for example, have disclosed positions in both bitcoin and ether ETFs in their latest 13F filings. While the allocations appear small relative to their overall portfolios, the disclosures show how digital assets have moved from the fringe of institutional finance into the mainstream toolkit.
For endowments facing lower expected returns from stocks and bonds, crypto ETFs can serve as a high-risk, high-volatility satellite position.
Still, panelists made clear that the broader challenge extends beyond any single asset class. Many institutions are tempering expectations after years of strong market performance. Equity risk premiums look thin, private markets hold record amounts of unsold assets and macro uncertainty remains elevated.
“I think it's a really hard setup for outstanding returns,” Lew said.
