Interest is a price of money, which is considered as a function of inflation, where nominal interest includes real interest plus rate of inflation. It also takes into consideration the factors like opportunity cost, risk of default and tenor of borrowing.
Expectations concerning inflation and economic stability are of crucial importance for any market. It is difficult to prepare a formula as to how interest rate expectations are generated. Confidence in the inflation target may provide an anchor. Past inflation rates will influence the inflation in future.
Confidence in monetary policy makes interest rates move with the expected inflation target. This contributes to stabilizing inflation around the target. The expectations channel thus amplifies the effects of monetary policy.
When interest rates are low, demand of credit for consumption and business will be higher. Higher demand leads to higher output and employment. Wage growth also picks up. The wage growth combined with higher profit margins will lead to higher demand for goods and services. High growth of money causes rise in inflation. Inflation can also change due to fluctuations in real demand for goods and services or sometimes due to the changes in the supply or demand for money. The current rise in interest rates is due to expectation of higher inflation movement. |
