The House last month passed a bill that would peg student loan rates to the interest rate of 10-year Treasury notes plus 2.5 percent. The rate for Stafford loans would fluctuate from year to year but could not exceed 8.5 percent. The rate for Direct PLUS loans for graduate students and parents would be set at 4.5 percent above the Treasuries rate and capped at 10.5 percent. […]Obama’s plan, contained in his budget, would set student lending rates to the 10-year Treasury rate plus 0.93 percent for subsidized loans but lock in those rates for the life of the loan. His proposal would cap interest at 10 percent of a borrower’s income. The rate for unsubsidized loans would be tied to the 10-year Treasury note rate plus 2.93 percent.
