New to this? Start with the explainer: Why Does College Keep Getting More Expensive? →

For decades the fix for expensive college was more lending. In 2026 Washington reversed the logic and started limiting it, on the exact theory this explainer describes.

In Brief

• A 2025 law overhauled federal student lending, capping graduate borrowing and ending unlimited Grad PLUS loans starting July 2026.
• The stated rationale is pure Bennett hypothesis: unlimited lending let colleges raise prices, so capping loans should pressure them down.
• Critics warn the caps could price lower-income students out rather than force schools to cut costs.
• Both fears can be true, which is what happens when you finally act on the incentive but only from one side.
• The test isn't whether loans fall. It's whether tuition follows or students just get shut out.

For half a century American policy treated expensive college as a problem to be solved with more generous loans. In 2026 that logic flipped. A sweeping law began capping how much students, especially graduate students, can borrow, and ended the program that let them borrow up to the full cost of a degree. The explainer laid out the theory that easy lending inflates tuition. Now Washington is betting on that theory in reverse.

The policy is the Bennett hypothesis turned into law

The reasoning behind the caps is striking because it's the exact mechanism from the explainer. The Education Department argued that when the government promises to lend whatever a degree costs, a college could simply raise the price and the federal government would be required to write a check. Remove the blank check, the logic goes, and colleges lose the ability to raise prices at will. After decades of the opposite approach, the government is treating easy loans as the cause of high tuition, not the cure.

For fifty years we fought high tuition by lending more. Now we're fighting it by lending less: same theory, opposite lever.

But capping loans only touches one side of the machine

Here's the catch the explainer predicts. The incentive problem has two halves: subsidized demand and unconstrained price. Capping loans attacks the demand side, but nothing in the law forces colleges to actually lower tuition. So there are two possible outcomes. Either schools cut prices to stay within what students can now borrow (the intended result), or prices stay high and students who can't cover the gap simply don't enroll. The policy assumes the first; critics fear the second.

Remove the easy money and a college must either drop its price or lose the student. The law is a bet on which.

Who absorbs the shock decides if it worked

The honest uncertainty is about who bears the cost. If well-resourced universities with big endowments absorb the hit and trim prices, the caps work as intended. If instead the squeeze lands on students, particularly lower-income ones who relied on those loans to reach graduate and professional programs, then the policy will have reduced debt by reducing access, which is a very different achievement. Early on, that distribution is exactly what's unresolved.

A cap that makes colleges cheaper is reform. A cap that just makes them exclusive is retreat dressed as reform.

What to actually watch

Don't watch the loan totals. Of course they'll fall; that's mechanical. Watch tuition. If sticker prices at affected programs start dropping in the years after the caps bite, the Bennett logic held and the policy worked. If tuition holds steady while enrollment among lower-income students falls, the caps shifted the pain onto students instead of the schools. That's the number that tells you which bet paid off.

The loans will shrink no matter what. Whether the price shrinks with them is the entire question.
