Interest is the cost paid for the use of money over a certain period of time. It is determined by banks, central banks, and other financial institutions and plays a critical role in guiding economic activity and financial markets.

In the forex market, interest rates directly influence currency values, as changes in rates affect capital flows between economies. In the cryptocurrency ecosystem, interest opportunities are offered through decentralized finance (DeFi) applications. DeFi protocols allow investors to earn interest by lending cryptocurrencies or providing liquidity to decentralized platforms.

Understanding interest rates is essential for evaluating investment opportunities, managing risk, and analyzing market movements across both traditional finance and digital asset markets.
