A borrower who has already repaid nearly double her original loan still owes $137,000, exposing the harsh mechanics of private student debt that millions more Americans may soon face.
Samantha Ferguson borrowed just over $104,000 from Sallie Mae in 2003 to study politics in Scotland, a path that disqualified her from federal student loans. Over the past 17 years, she has paid roughly $200,000 toward that debt. Her remaining balance sits at $137,000. The culprit is interest capitalization: unpaid interest gets folded into the principal, and the balance compounds. Ferguson, now 40 and recently laid off from a media job that paid about $116,000 a year, is struggling to secure any meaningful relief on her $1,500 monthly payments. As Business Insider reported, she has received conflicting guidance from servicer MOHELA and feels trapped in a system designed to extract payments indefinitely.
Her situation is not an outlier. It is a preview of what could await a much larger group of borrowers. President Trump's repayment overhaul, bundled into his broader spending legislation, introduces new borrowing caps for advanced degrees. When those caps take effect in July, students who hit their federal lending limits will have two choices: drop out or turn to private lenders. The private lending industry is already positioning itself for the influx. SoFi, Navient, College Ave, and Sallie Mae told Democratic lawmakers in February they are preparing for a surge. Sallie Mae CEO Jonathan Witter explicitly said the company views the federal reforms as an opportunity.
The core difference between federal and private student loans is not interest rates, though those matter. It is structural flexibility. Federal loans offer income-driven repayment plans that cap monthly bills at a percentage of discretionary income, along with forgiveness programs like Public Service Loan Forgiveness and options for discharge in bankruptcy that have become somewhat more accessible since 2024. Private loans offer none of these protections as standard practice. Borrowers who refinance federal debt into private loans permanently surrender those safeguards, and there is no mechanism to reverse the transaction.
This trade-off becomes especially dangerous during job losses, medical emergencies, or recessions. Ferguson's case illustrates exactly why. Her lender's primary relief option is forbearance, which pauses payments but allows interest to keep accruing and capitalizing. That means the debt grows while the borrower catches their breath. She has no children, no retirement savings, and no other debt. Her student loans have consumed her financial life for nearly two decades.
The Market Stakes
The outstanding student debt in the United States has surpassed $1.77 trillion, according to data from the Education Data Initiative. Roughly 92 percent of that is federal. But the private segment, which serves an estimated 7 to 8 percent of all student borrowers, carries outsized risk precisely because it lacks the safety valves built into the federal system. Interest rates on private loans in 2026 range from 4 percent to over 12 percent depending on creditworthiness, often exceeding the fixed rates available to federal graduate borrowers in prior years.
For investors and lenders, the coming wave of federal borrowers entering the private market represents growth potential. For policymakers and consumer advocates, it represents a systemic vulnerability. Borrowers pushed into private loans during periods of economic stress are more likely to default, more likely to face collections, and far less likely to recover financially. The Consumer Financial Protection Bureau has repeatedly warned that refinancing federal loans into private ones exchanges long-term flexibility for short-term rate savings, a calculation that can look smart in a stable economy and catastrophic in a downturn.
There is also a bankruptcy dimension. While the Justice Department introduced streamlined processes for discharging federal student loans in bankruptcy proceedings during 2024, private student loans remain subject to the much stricter undue hardship standard, making discharge in court exceedingly rare. Borrowers like Ferguson have essentially no legal exit ramp.
The broader warning here is not just about one borrower or even one servicer. The Trump administration's borrowing caps for graduate and professional programs will funnel a new cohort of students into a market designed without their protections. If the economy softens, which TD Economics and other analysts have cautioned is increasingly plausible given tightening financial conditions, those borrowers will enter a system where the only real option is to keep paying on a balance that refuses to shrink.
