Gilt Funds vs Buying G-secs Directly: The 10-Year Cost of Convenience
A gilt fund and a directly held G-sec contain the same thing: Government of India credit. That makes this a rare comparison where you can isolate what you’re paying for, because the only differences are structure, fees and control.
The cost, compounded honestly
Gilt fund expense ratios typically run 0.3–0.9%, with direct plans at the lower end. Take 0.5% on a ₹10 lakh holding earning a 6.8% gross yield:
| Years | Direct G-sec (6.8%) | Gilt fund (6.3% net) | Convenience cost |
|---|---|---|---|
| 5 | ₹13.90L | ₹13.57L | ₹0.33L |
| 10 | ₹19.32L | ₹18.42L | ₹0.90L |
| 20 | ₹37.3L | ₹33.9L | ₹3.4L |
That’s close to a lakh per decade per ₹10 lakh, for holding an instrument you could hold yourself at zero cost on RBI Retail Direct. It’s also only half the story, because the fund buys real things with that money.
What the expense ratio buys
Liquidity. T+1 redemption at NAV, any amount, whenever. Direct G-secs exit through NDS-OM’s retail-sized order book, which is fine for benchmark issues and patience-testing otherwise.
No maturity management. The fund rolls its positions indefinitely. A direct G-sec matures and hands you a reinvestment decision, though a ladder automates the thinking if not the clicking.
Duration management. Dynamic gilt funds shift duration with rate views. Whether that’s worth paying for is debated, since plenty of them are riding a curve you could ride yourself.
Small tickets and SIPs. ₹500 a month into a gilt fund works. Auction lots start at ₹10,000 per bid.
The tax layer, which flipped in 2023
Gilt fund gains are now taxed at slab regardless of holding period. Direct G-secs pay slab on coupons but 12.5% LTCG on price gains beyond 12 months, and a G-sec bought below par at auction or on-market carries a built-in LTCG component at redemption. For investors in the 20–30% slabs that quietly widens the direct route’s advantage beyond the expense ratio. Full mechanics here. Pushing the other way, funds defer tax until redemption while direct coupons are taxed every year.
The NAV problem nobody warns retirees about
A gilt fund never matures, so its NAV carries duration risk permanently. A retiree sitting “safely in gilts” through a rate shock can watch an 8% drawdown on money earmarked for next year’s expenses. Someone holding a bond that matures next year doesn’t care what prices do meanwhile.
Funds convert maturity certainty into perpetual price exposure. That’s the design rather than a flaw, and it’s the difference people misunderstand most often.
The verdict grid
| You | Verdict |
|---|---|
| Goal-dated money, any size | Direct, because maturity certainty is the product |
| ₹500–5,000/month SIP into safety | Gilt fund, since direct isn’t practical |
| Retiree income book | Direct ladder, for the NAV reason above |
| Tactical rate view (“yields will fall”) | Fund for easy entry and exit, or a long direct G-sec if you’d hold it anyway |
| Can’t be bothered, ever | Direct-plan gilt fund, accepting the ~0.5% toll |
| 20%+ slab, multi-year horizon | Direct, for the LTCG edge on top of the fee edge |
Doing the direct route well
The friction is front-loaded. Open one Retail Direct account and after that auctions take about two minutes. Buy re-issues of benchmark securities if you might sell early, check any secondary-market price against fair value with the YTM calculator, and size long tenors using the duration calculator so a rate spike never catches you out.
FAQ
Are constant-maturity gilt funds different? They pin duration, usually around 10 years, rather than managing it. Cleaner exposure, same fee and no-maturity caveats.
What about G-sec ETFs? Lower fees than active gilt funds, with exchange liquidity that varies, so check tracking difference and spreads. The direct-versus-wrapper logic doesn’t change.
Is there a size below which direct isn’t worth it? Below roughly ₹50,000 in total the admin per rupee stops making sense and funds win on practicality. Above a few lakh, the fee math takes over.
