Assuming anaemic GDP growth of just 1.5% a year as opposed to 2.6%, and a nominalinterest rate of 4% rather than 2.8%, us debt rises to 157% of GDP in 2020.
Because the given period isn't campatibile, the real interest rate of bank deposits or loans isn't in accord with the nominalinterest rate announced by bank.
Other things being equal (such as roughly similar real interestrates across countries) nominalinterest rates should be higher incountries with higher inflation rates.
