Honestly, you're not overthinking — this is actually one of the smartest questions to ask before parking money somewhere.
First, your fear about NAV going down. Liquid funds invest in instruments maturing within 91 days — government T-bills, commercial paper, certificates of deposit. They don't move like equity. In the last 10 years, there have been maybe 2-3 days of negative returns in the entire liquid fund category. The risk is extremely low, not zero, but extremely low. Your FD can also get locked, so liquid fund actually wins on accessibility.
For emergency fund specifically, here's what I'd suggest:
**Split your ₹2.3L like this:**
- ₹50,000 in a high-interest savings account — IDFC First Bank or AU Small Finance Bank give 6-7% on savings, instant access
- ₹1.8 lakh in a liquid or overnight fund
The savings account chunk covers immediate 1-day emergencies. The fund covers bigger needs that give you a day's notice.
**Specific funds worth looking at in 2026:**
- Mirae Asset Overnight Fund — very clean portfolio, no credit risk nonsense
- HDFC Liquid Fund — one of the oldest, consistent
- Parag Parikh Liquid Fund — they're conservative, won't chase yield by taking weird bets
Overnight funds are slightly lower return than liquid funds but have almost zero volatility. Liquid funds give maybe 0.3-0.5% more annually. For emergency money, I'd personally go overnight fund — peace of mind is worth that small difference.
Redemption reality: most funds now have instant redemption up to ₹50,000 or 90% of folio value via Coin, Groww, or direct AMC apps. So the "can I get money fast" concern is mostly solved now.
One thing most people get wrong — they put emergency fund in a regular FD thinking it's safe. Then when emergency hits, premature withdrawal cuts interest and sometimes takes 2-3 working days. Liquid fund beats this hands down.
Go with Parag Parikh Liquid Fund or Mirae Overnight Fund, invest directly through AMC website or Coin app, and stop feeling guilty about that savings account. You're doing the right thing.
