Plans to cap student loan interest rates could bring significant financial relief to thousands of graduates across Wales, following an announcement from the Welsh Government.

Vikki Howells confirmed that ministers have agreed in principle to a UK Government proposal to limit interest rates on Plan 2 and Plan 3 student loans to 6% from September 2026, covering the 2026–27 academic year.

However, the move is not yet final and will require approval from the next Welsh Government as well as the Senedd after the upcoming election.

If introduced, the cap would mark an important shift in how student loan debt grows for Welsh borrowers. In recent years, interest rates on student loans have risen sharply due to high inflation, at times exceeding 7%. Because the system links interest to inflation, many graduates have seen their overall debt increase rapidly, even while making repayments.

The proposed cap would effectively put a ceiling on that growth, offering more stability and predictability for borrowers. While repayments are still based on income and only begin once earnings pass a set threshold, the level of interest applied plays a major role in how much graduates ultimately repay over time. By limiting the rate to 6%, the Welsh Government hopes to ease some of the long-term financial pressure associated with higher education.

The current system has developed over more than a decade, following wider UK reforms that saw tuition fees rise and repayment models change. Under Plan 2 and postgraduate Plan 3 loans, interest rates are tied to the Retail Price Index, meaning they can fluctuate significantly depending on economic conditions. During periods of high inflation, such as those seen in recent years, this has led to growing concern among students and graduates about the rising cost of borrowing.

The proposed cap forms part of a broader response to those concerns, aimed at protecting borrowers from sharp increases while maintaining the overall structure of the student finance system.

Despite the positive reaction from ministers in Wales, the policy is not yet guaranteed. Any formal decision will be made by the next Welsh Government and will need to be approved by the Senedd before coming into force.

For now, the announcement signals a clear intention to provide greater protection for Welsh students and graduates, and could represent a step towards a fairer and more manageable system in the future.
