Interest rates

When A lends money to B, B repays the amount lent by A (the capital) as well as a supplementary sum known as interest, so that A has an interest in agreeing to this financial operation. The interest is determined by the interest rate, which may be high or low. To take a very simple example : if A borrows 100 million dollars for 10 years at a fixed interest rate of 5%, the first year he will repay a tenth of the capital initially borrowed (10 million dollars) plus 5% of the capital owed, i.e. 5 million dollars, that is a total of 15 million dollars. In the second year, he will again repay 10% of the capital borrowed, but the 5% now only applies to the remaining 90 million dollars still due, i.e. 4.5 million dollars, or a total of 14.5 million dollars. And so on, until the tenth year when he will repay the last 10 million dollars, plus 5% of that remaining 10 million dollars, i.e. 0.5 million dollars, giving a total of 10.5 million dollars. Over 10 years, the total amount repaid will come to 127.5 million dollars. The repayment of the capital is not usually made in equal instalments. In the initial years, the repayment concerns mainly the interest, and the proportion of capital repaid increases over the years. In this case, if repayments are stopped, the capital still due is higher…

The nominal interest rate is the rate at which the loan is contracted. The real interest rate is the nominal rate reduced by the rate of inflation Inflation Hausse cumulative de l’ensemble des prix (par exemple, une hausse du prix du pétrole, entraînant à terme un réajustement des salaires à la hausse, puis la hausse d’autres prix, etc.). L’inflation implique une perte de valeur de l’argent puisqu’au fil du temps, il faut un montant supérieur pour se procurer une marchandise donné. Les politiques néolibérales cherchent en priorité à combattre l’inflation pour cette raison. .
