Why Do interest rates fall and rise?

Interest rates rise and fall primarily due to changes in monetary policy, inflation expectations, and economic conditions. Central banks, such as the Federal Reserve, adjust rates to influence borrowing and spending; lowering rates encourages economic growth, while raising rates aims to curb inflation. Additionally, factors like supply and demand for credit, global economic trends, and market sentiment can also impact interest rates. Overall, these fluctuations reflect the balance between economic growth and inflation control.
