Interest rate risk is a crucial concept in the world of finance. It refers to the potential impact of fluctuating interest rates on the value of an investment. Simply put, it is the degree to which a financial instrument is affected by changes in interest rates. As interest rates rise or fall, the value of an investment may also rise or fall accordingly. This is an important consideration for investors, as it can influence their decision-making and portfolio management strategies. So, understanding interest rate risk is essential for any investor looking to make informed financial decisions.
