What is a Money Market Fund?
A Money Market Fund (MMF) is a debt mutual fund that exclusively invests in short-term, high-quality money market instruments with a maturity of up to 1 year. These instruments include:
- Treasury Bills (T-Bills) — Government of India short-term paper (91-day, 182-day, 364-day)
- Commercial Papers (CPs) — Unsecured short-term instruments issued by highly-rated corporates
- Certificates of Deposit (CDs) — Time deposits issued by banks and financial institutions
- Repos and Tri-party Repos (TREPs) — Short-duration collateralised borrowing
Because all instruments mature within a year and the portfolio is highly diversified, money market funds carry very low credit risk and virtually no interest rate risk.
Liquid funds can hold instruments up to 91 days maturity. Money market funds hold instruments up to 1 year. This slightly longer duration gives MMFs marginally higher returns than liquid funds (typically 20–50 bps extra) while remaining extremely stable.

Key Advantages of Money Market Funds
- Capital preservation — T-Bill and A1+ CP focus ensures near-zero default risk
- Better than savings accounts — 2–3x higher returns with similar accessibility
- No lock-in — unlike FDs, no premature withdrawal penalty
- SIP friendly — automate surplus parking from salary every month
- Scalable — efficient for large corpuses (HNIs and corporates use heavily)
Gains from money market funds are now taxed at your income slab rate regardless of holding period. The old 20% LTCG with indexation (for >3 year holdings) has been removed. This makes MMFs less tax-efficient than arbitrage funds for investors in the 30% tax bracket holding for >3 months.
Who Should Invest in Money Market Funds?
- Investors parking emergency funds (3–6 months expenses)
- Businesses managing working capital surpluses
- Individuals in the 10–20% tax bracket seeking better-than-FD returns
- Anyone saving for a short-term goal (6–12 months away)
- NRIs with NRO account funds seeking safe parking
