In late April and early May, Moody's and Fitch issued three higher education credit downgrades in rapid succession. Northern Illinois University was pushed below investment grade to Ba1, making it the first public university in this cycle to land in junk territory, with 301 million dollars in outstanding debt and what Moody's called "a difficult operating environment" of wage pressures and spending growth. The University of Chicago was cut from AA+ to AA by Fitch, which noted that "operating deficits persist" and "macro expense pressures have mounted, particularly labor and supplies." American University dropped to A2 from A1, with Moody's projecting operating deficits through fiscal 2028. These are not obscure community colleges. One of them charges over 103,000 dollars a year. Columbia University sold 487 million dollars in bonds in May after Moody's revised its outlook to negative, the step that typically precedes a downgrade. The agency kept Columbia's Aaa rating intact but flagged a number that should concern anyone lending to a university: Columbia's total cash and investments stand at 2.7 times operating expenses, against a median of 10.7 times for Aaa rated private universities. Its operating surplus fell 63 percent in fiscal 2025. Private giving declined nearly 10 percent. Endowment gifts dropped over 25 percent. International students, who make up 39 percent of enrollment and contributed an estimated 903 million dollars in economic activity in 2023, represent over 60 percent of net tuition revenue. Columbia is borrowing at the top of the credit scale while holding reserves closer to the middle. The downgrades are not isolated events. All three major rating agencies, Moody's, Fitch, and S&P, issued negative sector wide outlooks for higher education in 2026, the first time the three have converged on that signal simultaneously. Moody's projects sector expenses growing at 4.4 percent against revenue growth of 3.5 percent. S&P recorded 30 higher education downgrades in 2025 and only 3 upgrades in the first quarter of 2026. Fitch Senior Director Emily Wadhwani warned that the 2025 26 academic year "is expected to be the high point for enrollment with declines projected every year afterward," a reference to the demographic cliff created by falling birth rates after the 2008 financial crisis. The Western Interstate Commission for Higher Education projects high school graduates will decline by 13 percent by 2041, eliminating roughly 576,000 potential students over a four year cycle. Yet universities are borrowing more, not less. According to Janney Montgomery Scott, 99 colleges and universities issued 20.8 billion dollars in public debt in 2025, up from 17 billion by 71 institutions the prior year. The borrowing is driven by deferred maintenance, competition for students through campus amenities, and rising construction costs. For institutions with strong credit, the math still works: an Aaa rating gives Columbia access to billions at favorable rates, and its bond sale was fully subscribed. But for schools at the lower end, downgrades widen the yield spread they must offer investors, shrink the pool of buyers willing to hold their paper, and make refinancing existing debt more expensive. Northern Illinois now borrows at junk rates. The cost of that capital is passed, eventually, to students and taxpayers. The bond market sees what enrollment dashboards and strategic plans often obscure. Credit analysts are not evaluating mission statements or campus culture. They are modeling whether an institution's revenue will cover its obligations over 20 to 30 years. When Fitch downgrades the University of Chicago, it is not making a statement about academic quality. It is saying that the gap between what the school earns and what it spends is widening, and the trajectory is not convincing. When Moody's flags Columbia's cash ratio at one quarter of the Aaa median, it is quantifying fragility that no amount of brand prestige can offset. More than 40 colleges have announced closures since 2020. Pennsylvania State University plans to shutter seven of its 20 branch campuses after spring 2027. For bondholders, the question is no longer which universities will thrive. It is which ones will still be open when the debt matures.
