Deep Dive
An interest rate represents the cost of borrowing money or the return on lending it, typically expressed as a percentage of the principal amount over a specific period, usually annually. For borrowers, it's the fee paid for the use of borrowed funds, impacting everything from mortgage payments and personal loans to corporate financing decisions. For lenders, it's the compensation received for relinquishing immediate use of their capital, reflecting factors like inflation expectations, the borrower's creditworthiness, and prevailing economic conditions set by central bank policies.
