Under the system proposed by Obama, the government would cut private lenders out of the picture entirely, setting the interest rates and collecting payments directly for all student lending.
Whether or not the government saw a profit or a loss from the new, federal loans would depend on the rate at which the government borrows money. For instance, the law currently sets the interest rate for direct loans at a maximum of 6.8 percent.
Under Obama’s proposal, if the government can borrow money at a rate lower than 6.8 percent, it would realize the difference as profit. If the government’s borrowing rate were to fall in the future, its profit on student loans would grow.
The idea to nationalize student lending was first put forth in President Obama’s fiscal-year 2010 budget and marketed as a way to save the government billions of dollars. According to a CBO estimate, the proposal would save the government $87 billion over 10 years.
The savings estimate results from the fact that the government believes it will collect more in interest payments from students than it would otherwise have to pay in fees to lenders
