What is money market yield（MMY）？

Money market yield (MMY) is the annualized return on investment for short-term, low-risk financial instruments such as Treasury bills, certificates of deposit (CDs), and commercial paper. It represents the interest rate earned by investors on their money market investments and is calculated by dividing the annual interest earned by the investment by the investment's face value. The MMY is often used as a benchmark for other short-term investments and is an important metric for investors seeking low-risk, stable returns.
