English and Welsh graduates who have taken out student loans since 2012 can expect a "rollercoaster ride" when it comes to interest rates, new analysis shows.
This will mean students are charged higher rates of interest on their loans than homeowners paying off mortgages.
The Institute for Fiscal Studies (IFS) has calculated that because of current RPI inflation rates, the maximum interest rate on loans - paid by those earning £49,130 or more - will rise from current rates of 4.5% to an "eye-watering" 12% for half a year.
