Understanding Interest Rates

Interest rates are the rates at which individuals or financial institutions charge or earn over a specific period of time as a result of borrowing or investing. These rates are not limited to money but can also apply to other financial assets such as cars, houses, or cryptocurrencies.

When individuals borrow money, they are charged an interest rate. This rate is usually expressed as an annual percentage rate (APR), which represents the amount paid in interest each year relative to the total loan amount. For instance, a 5% APR means that 5% of the loan amount is paid in interest annually.

On the flip side, lenders and investors benefit from interest rates as they earn profit on their investments. This can include interest earned from holding cash in a savings account. The profit is typically expressed as an annual percentage yield (APY), which represents the expected yield earned per year from the investment.

In the realm of cryptocurrency, interest rates function similarly to traditional finance but with added complexity. Because of the volatile nature of cryptocurrencies, the absolute value of interest can fluctuate significantly over a given period, even if the APR or APY remains constant.

This fluctuation is due to the relationship between the interest rate and the principal amount, which refers to the borrowed or deposited amount. If the principal amount increases in value, the absolute value of the interest will also increase proportionally. However, this is not the case if the rates are pegged to a specific fiat currency like the US dollar at the time of borrowing or depositing.
