Understanding Interest Rates
Imagine you borrow $100 from a friend. In return, you agree to pay back more than $100 — say $110. The extra $10 is the interest rate. This cost of borrowing is what we call an interest rate. When banks lend money to individuals or businesses, they charge this rate as compensation for the risk and opportunity cost of lending.
A deeper explanation
Interest rates are a price mechanism in financial markets that determine how much it costs to borrow money or how much you earn by lending it. They influence consumer spending, business investment, and inflation. For example, when interest rates rise, borrowing becomes more expensive, which can slow down economic activity. Conversely, lower rates encourage spending and investment. Central banks adjust these rates to manage the economy’s health.
