Why are interest rates essential in an economy?

Interest rates play a crucial role in an economy as they determine the cost of borrowing money and the returns on savings. When interest rates are low, borrowing becomes cheaper, encouraging individuals and businesses to take loans for investments, which can stimulate economic growth and consumer spending. Conversely, higher interest rates can discourage borrowing, potentially slowing down economic activity.

Additionally, interest rates directly influence the returns that savers receive on their deposits, impacting household savings behavior and overall financial stability. This dual function of facilitating borrowing and incentivizing saving makes interest rates a pivotal factor in economic decision-making, investment strategies, and overall economic health.
