Explanation:

For example, I borrow $50,000 at an 8% interest rate while my neighbor has a CD that pays him 4% yearly interest. If the inflation rate unexpectedly increases by 2%, then the real interest that I will pay will be 6% (I will pay less), while the real interest rate that my neighbor will get will be only 2% (he will earn less).
