Heavy investment in private equity backfires, Princeton endowment fund lowers "return expectations," seriously impacting university development.

Due to the decline in long-term returns caused by crowding in the private equity market, Princeton University has been forced to sharply cut its long-term return expectations for its $36 billion endowment fund. This marks a severe challenge to the longstanding investment model of relying on illiquid assets for high returns, and has directly triggered budget cut plans within the university. On February 3, according to the Financial Times, Princeton University President Christopher Eisgruber stated in his annual letter released this Monday that, due to excess capital chasing limited investment opportunities, “market fundamentals are changing,” which will lead to a continued decline in long-term returns. Therefore, the Princeton endowment has reduced its expected return from 10.2% to 8%. The financial impact of this change in expectations is enormous. It is estimated that over the next decade, this will cause Princeton’s endowment assets to decrease by about $11 billion, a figure that exceeds the total proceeds of the university’s past two major fundraising campaigns. As a result, Princeton has sought to reduce university-wide spending by 5% to 7% over the past 12 months. Eisgruber made it clear that the continuing decline in endowment returns will require “more targeted, and sometimes even larger reductions” over the next few years. It is noteworthy that previously, many institutional investors—including pension funds and university endowments—rushed into the private market without fully accounting for risk. As Britt Harris, former Chief Investment Officer of University of Texas/Texas A&M Investment Management Company said: “They rushed into a crowded parking lot, and now no one can get out.” Double-digit Return Era Ends Reportedly, Princeton’s move reflects a reassessment of the long-term market environment by institutional investors. Britt Harris pointed out that in the current environment, “it is nearly impossible to hold a diversified portfolio and achieve double-digit return targets for a long period of time.” He believes Princeton has merely “returned to normal.” Over past decades, Princeton’s endowment had greatly benefited from aggressive bets on private equity. By June 2025, private equity accounted for over two-fifths of its investment portfolio. Eisgruber explained, “This strategy worked in the past because elite institutions like Princeton had access to highly attractive investment opportunities. However, as more investors have crowded into the sector, these advantages have vanished.” A high interest rate environment has, in the short term, suppressed IPOs and mergers and acquisitions, slowing exits; in the long run, oversupply of capital has intensified competition for deals, directly squeezing returns. Performance Declines and Long-term Concerns Reportedly, “the data decline proves this trend.” Eisgruber revealed that Princeton’s endowment fund achieved a historic high of 47% in 2021, but in the following years delivered “one of the worst periods in the university’s history.” This is the first time the fund has reported two consecutive years of negative returns. From a longer-term perspective, the outlook is equally worrying. Princeton endowment’s 20-year rolling return rate has steadily fallen from over 14% in 2005 to less than 10% by 2025. Faced with this trend, Eisgruber candidly stated: “We may be too pessimistic, but it’s very possible we’re still too optimistic.” A Warning Against Over-Betting on PE Reports say that for Princeton University, which relies heavily on its endowment fund, cutting return expectations has far-reaching impact on institutional development, especially against the backdrop of federal funding cuts under the Trump administration. Britt Harris warned: “Princeton’s overexpansion into private equity is a lesson for other university endowments. ‘If you do a good thing to excess, now you have to pull it back.’” This case shows that the once-golden “Yale model”—heavily investing in illiquid assets in exchange for hefty premiums—is now facing an unprecedented stress-test.
