Traditionally, borrowers have benefited more from inflation, because the money they pay back is worth less than when they borrowed it. That is why, when inflation rises, the interest rate charged by lenders also rises.
e.g. If I borrow 3% money to buy a house for $50,000, and inflation rises to 6%, over time I have paid back significantly less than the purchasing power equivalent of my original loan.
Real intrest rate decreased during inflation times. Inflation rate is deducted from nominal intrest rate ( actually paid or received amount) is called real intrest rate. Based on real intrest rate can calculate the interest paid or received. Here creditors are lose and debtors are gains because of the depreciation of currencies.
