How do changes in the money supply affect the cost credit?

Changes in the money supply directly influence the cost of credit, typically reflected in interest rates. When the money supply increases, there is more liquidity in the economy, which tends to lower interest rates, making borrowing cheaper. Conversely, when the money supply contracts, credit becomes scarcer, leading to higher interest rates and increased borrowing costs. Thus, adjustments in the money supply can significantly impact the availability and affordability of credit.
