Liquid & Overnight Funds
Park-your-cash funds: very short-maturity debt, low risk, a better home for idle money than a savings account.
Why you care
Liquid funds hold very short-maturity debt — money-market instruments maturing in weeks, not years — so they barely move day to day and carry little of the duration risk that bites longer debt funds. They're built for one job: a sensible home for cash you'll need soon, usually yielding a bit more than a savings account.
Run the numbers
Idle ₹5 lakh in a savings account earns ~3%; in a liquid fund it might earn a bit more with very low volatility (illustrative — yields track short-term rates). Redemptions are fast, often next-day, though a small graded exit load applies if you pull out within the first week.
Where this goes
Why you care
Liquid and overnight funds are debt funds that hold only very short-maturity instruments — overnight funds invest in securities maturing the next day, liquid funds in instruments maturing within about 91 days. That short maturity is the whole safety story: with almost no duration, a rate move barely dents their NAV, so they're about as steady as a market-linked product gets. They exist for parking money, not growing it.
The everyday use is the money you don't want in equity and don't want dead in a savings account. Think an emergency fund, a house down-payment you'll need in six months, or a bonus you haven't deployed. A liquid fund typically yields a little more than a savings account while staying low-risk and quick to redeem, often crediting your money the next working day. Two caveats keep it honest. They are low-risk, not no-risk — a liquid fund holds short-term corporate paper, which can still take a credit knock, as one or two funds have shown. And there's a small graded exit load if you redeem within the first seven days, designed to discourage same-week in-and-out churn.
Run the numbers
₹5 lakh you'll need in a few months (illustrative):
- In a savings account: earns ~3%, fully liquid.
- In a liquid fund: earns a bit more, tracking short-term money-market rates, with very low day-to-day movement and next-day redemption after the first week.
The gain over a savings account is modest in rupees, but the real value is having a low-drama place for cash that isn't sitting idle. The other common use is as a launchpad: drop a lump sum into a liquid fund and set up a systematic transfer plan (STP). That moves a fixed amount each month into an equity fund, so you get the discipline of averaging in rather than betting everything on one day's market level.
Where this goes
Liquid funds are simply the shortest, safest rung of the debt fund ladder, useful as the reference point for what "low duration risk" actually looks like. They also connect to behaviour: an STP out of a liquid fund into equities is the lump-sum investor's version of a SIP, turning a scary all-at-once decision into a steady, automatic drip.
