What Is a Money Market Mutual Fund?
A money market mutual fund is a type of debt mutual fund that invests exclusively in money market instruments, which are short-term debt instruments with maturities up to one year, such as treasury bills, commercial paper, certificates of deposit, and call money. SEBI defines money market funds as those investing in instruments with maturities up to one year. They offer very low risk, high liquidity, and returns moderately above savings account rates, making them suitable for short-term cash parking and conservative investors.
How Money Market Funds Differ from Liquid Funds
| Parameter | Money Market Fund | Liquid Fund |
|---|---|---|
| Maturity of instruments | Up to 1 year | Up to 91 days |
| Duration | Slightly higher | Very short (15-30 days average) |
| Return potential | Slightly higher than liquid | Slightly lower |
| Risk | Very low | Very low |
| Suitable for | 3-12 month investment horizon | 0-3 month investment horizon |
Instruments Held in Money Market Funds
- Treasury bills (T-bills): 91-day, 182-day, or 364-day government securities; zero credit risk.
- Commercial paper (CP): Short-term unsecured promissory notes issued by corporations; slightly higher yield than T-bills.
- Certificate of Deposit (CD): Issued by banks and financial institutions; highly liquid.
- Call money: Overnight to 14-day interbank lending market instruments.
Returns and Tax Treatment
Money market funds typically return 6-8% annually depending on prevailing short-term interest rates. Taxation applies at slab rate for investments made after April 2023, same as other debt funds. For investors in the 30% tax bracket, post-tax returns are closer to 4-5%, which may be comparable to savings account returns for short periods.
When to Use a Money Market Fund
- For investments planned within 3 months to 1 year.
- As an alternative to short-duration FDs without the lock-in restriction.
- For corporate treasury management where short-term fund parking is needed.
- As a stepping stone before deploying into equity through STP.
