Gilt Funds.
Zero Credit Risk. Full Rate Risk. Pure Duration Exposure.
Published as on 17 June 2026
Gilt Funds are debt mutual funds that invest at least 80% in Government of India securities (G-Secs) and State Development Loans (SDLs). They eliminate credit risk (sovereign backing) but retain full interest rate risk — NAV moves opposite to rate direction. SEBI created two subcategories: regular (flexible duration 3-7 years typical) and 10-yr constant duration (always ~10 years, higher volatility). Feb 2026: RBI repo at 5.25% after 125 bps cuts during 2025. Tax under Finance Act 2023: slab rate always, identical to FDs. Tools for high-quality debt allocation and duration positioning, not FD substitutes.

Executive Summary · 6 Findings
Gilt Funds separate the two engines of debt risk — they eliminate credit risk (sovereign-backed) while retaining interest rate risk in concentrated form. This makes them precise tools for duration positioning, not FD substitutes. Feb 2026: RBI at 5.25% after 125 bps cuts. The easy money from the cutting cycle is largely captured.
Covers SEBI's two gilt categories (regular and 10-yr constant), the Macaulay duration framework (rubber band analogy), risk separation between credit and rate risk, comparison with FDs/PPF/Corporate Bond, tax under Section 50AA, four tactical strategies (core-satellite, SIP, rate cycle, tax harvesting), and the seven retail questions.
Key Findings
SEBI 80% G-Sec mandate — sovereign exposure only.
Per SEBI, Gilt Funds must invest at least 80% in government securities. Two subcategories: (1) Regular Gilt Fund — flexible duration 3-7 years typical, manager adjusts. (2) Gilt Fund with 10-Year Constant Duration — always ~10 years, mechanical rebalancing. Sovereign backing eliminates credit risk; market liquidity risk during extreme stress (March 2020) is theoretical but minor.
Two risks separated: credit eliminated, rate amplified.
Corporate bonds carry both credit risk (company default) and interest rate risk. Gilt funds isolate the rate risk completely. Sovereign default risk is virtually zero. This separation lets you manage risks independently — choose credit risk via Corporate Bond Funds, choose rate risk via Gilt Funds. Hybrid approach: 50% Gilt + 50% AAA Corporate Bond for sovereign safety plus 50-100 bps credit spread.
Duration math: 1% rate change → ~7% NAV swing (7-yr duration).
Duration × Rate Change = NAV Impact. 3-yr duration fund: ±3%. 7-yr duration regular gilt: ±7%. 10-yr constant duration: ±10%. 2022 example: RBI hiked 250 bps from 4% to 6.5%; long-duration gilt funds delivered -8% to -12%. 2025 example: 125 bps cuts; 10-yr gilt delivered 12-15%. Same fund, opposite direction.
Feb 2026 context: late-cycle, easy money captured.
RBI at 5.25% after 125 bps cuts during 2025. 10-yr G-Sec yield ~6.67-6.77%. Most rate-cut gains realised. Stable rate scenario: 6.5-7.5% accrual. Further 50 bps cuts: ~9-12%. Rate hike pivot: -5% to -8%. Asymmetric risk now. Use STP/SIP rather than lump sum to average entry.
Tax: slab rate always post-April 2023, identical to FDs.
Section 50AA: all gains taxed at slab rate regardless of holding period. No LTCG, no indexation. Pre-April 2023 grandfathered units redeemed post-July 23 2024: 12.5% LTCG after 24 months. Tax-deferral edge remains: FD interest taxed annually; gilt fund tax only at redemption. For 30%-slab over 5 years, ~0.3-0.5% effective annual boost.
Direct plan critical: 0.10-0.30% vs 0.50-0.80% Regular.
Gilt funds are essentially passive sovereign exposure — no active stock-picking justifies high distributor commissions. Direct plans 0.10-0.30%; Regular plans 0.50-0.80%. Over 10 yr on ₹10L at 7% gross: Direct ₹19.67L vs Regular ₹18.07L → ₹1.6L difference. Always Direct via AMC website, Coin by Zerodha, Kuvera, MF Utility.
At A Glance
| Metric | Value | Detail |
|---|---|---|
| Mandate | ≥80% G-Sec | SEBI rule |
| Credit Risk | Virtually Zero | Sovereign-backed |
| Rate Risk | High | Duration-driven |
| Regular Duration | 3-7 yr | Manager-flex |
| 10-yr Constant | ~10 yr | Mechanical |
| Min Horizon | 3-5+ years | Through cycle |
| Tax (post-Apr 2023) | Slab Rate | FD-identical |
| Direct Expense | 0.10-0.30% | Mandatory choice |
Exhibit 01: Rate-Cycle History
| Period | RBI Action | 10-yr Gilt |
|---|---|---|
| 2024-25 | Cut 6.5% → 5.25% | +12-15% |
| 2023-24 | Hold at 6.5% | +6-8% |
| 2022-23 | Hike 4% → 6.5% | -8% to -12% |
| 2019-20 | Cut to 4% | +12-15% |
Duration is the lever. The same fund delivers +12-15% during cutting cycles and -8% to -12% during hiking cycles. Hold through full cycles (3-5+ years) to ride out interim volatility.

The Opening
Gilt Funds invest exclusively in government securities — at least 80% per SEBI mandate — eliminating credit risk while retaining the full force of interest rate risk. The trade is precise: you trust the Government of India to repay (sovereign backing) but accept that bond prices fluctuate daily with rate movements. This isolates one risk engine from another and enables surgical portfolio construction.
"Gilt funds remove credit risk completely but concentrate interest rate risk. They are tools for duration positioning and high-quality debt allocation, not FD substitutes. The 10-year constant duration variant is a long rubber band that stretches and contracts dramatically with rate changes; the regular gilt fund is a shorter, more flexible rubber band where the manager adjusts tension."
The Risk-Separation Frame
The mathematics is honest. Duration × Rate Change = NAV Impact. A 7-year duration fund moves ~7% per 1% rate change. The 2022 hiking cycle (250 bps) delivered -8% to -12% for long-duration gilt funds. The 2024-25 cutting cycle (175 bps cumulative from 6.5% peak) delivered 12-15%. Same fund, opposite direction. Direction matters more than time.
Feb 2026 context. RBI at 5.25% after 125 bps cuts during 2025. 10-yr G-Sec yield ~6.67-6.77%. Late-cycle position. Easy money largely captured. If you're entering now: use STP or SIP over 6-12 months to average entry; match horizon to 3-5+ years; understand that further 50-100 bps cuts deliver moderate upside while a rate-hike pivot delivers meaningful downside.

How Gilt Funds Work, the Two SEBI Categories, and the Duration Math
The mechanics of holding government securities while NAV moves with rates, the difference between regular gilt (flexible 3-7 year duration) and 10-year constant duration (mechanical ~10 years), and the Duration × Rate Change formula that determines NAV sensitivity.
Part I · Page 4
Two SEBI Subcategories
| Feature | Regular Gilt | 10-Yr Constant |
|---|---|---|
| Duration | 3-7 yr typical | ~10 yr always |
| Manager Role | Active (flex) | Mechanical (rebal) |
| Volatility | Moderate-High | Very High |
| NAV / 1% rate | ±3-7% | ±10% |
| Best For | Strategic alloc. | Tactical bet |
Duration Math
The 1% Rule
3-yr duration: 1% rate change → ~3% NAV swing
7-yr duration: 1% rate change → ~7% NAV swing
10-yr duration: 1% rate change → ~10% NAV swing
The Rubber Band Analogy: Macaulay duration is the rubber band's resting length. Longer band = bigger stretch and contraction when rates change. 10-yr is the long band; 3-yr is the short one. Same physics, different magnitudes.
₹10,000 Example
| Scenario (7-yr Dur) | NAV | Value |
|---|---|---|
| Start | ₹100 | ₹10,000 |
| Rate -0.5% | ₹103 | ₹10,300 |
| Rate +0.5% | ₹97 | ₹9,700 |
| Rate stable | ~₹102-103 | Coupon accrual |
Why Sovereign Backing Matters
G-Secs are direct IOUs from the Government of India, repayable through sovereign taxation power. SDLs (State Development Loans) are quasi-sovereign — state governments have never defaulted on debt obligations. Settlement and liquidity risk during extreme market disruptions (March 2020 COVID freeze) is theoretical but minor for the sovereign curve.
Risk Separation Principle
| Fund Type | Credit Risk | Rate Risk |
|---|---|---|
| Liquid | Low | Minimal |
| Corporate Bond | Low | Moderate |
| Gilt | ~Zero | High |
| Credit Risk Fund | High | Moderate |
The pure play: Gilt funds isolate rate risk completely. You can manage credit risk and rate risk independently. Hybrid construction: 50% Gilt + 50% AAA Corporate Bond gives sovereign safety + 50-100 bps credit spread.
2025-26 Real-World Trajectory
Jan 2024: ₹10L at 6.5% peak repo.
Feb-Dec 2025: 125 bps cuts.
10-yr gilt fund: ~12-15% in 12 months.

Tax (Section 50AA), and Comparison with FDs / PPF / Corporate Bond
Why post-April 2023 slab-rate taxation made gilt funds tax-identical to FDs, the surviving tax-deferral edge for 30%-slab investors, and where PPF (7.1% tax-free) and Corporate Bond Funds legitimately compete based on credit and tax preferences.
Part II · Page 6
Tax — Post-April 2023
Section 50AA — Slab Rate Always
All gains taxed at slab rate regardless of holding period. No LTCG, no indexation.
30% slab: ₹5L → ₹6.5L in 3 yr. Gain ₹1.5L → tax ₹45K. Net ~6.6% post-tax.
20% slab: ₹10L → ₹14L in 4 yr. Gain ₹4L → tax ₹80K. Net ~7.2%.
5% slab: ₹2L → ₹2.3L in 2 yr. Gain ₹30K → tax ₹1,500. Net ~6.9%.
Pre-April 2023 Grandfathered
| Scenario | Tax |
|---|---|
| Sold post-Jul 23 2024, >24 mo | 12.5% LTCG (no index.) |
| Below threshold | Slab |
Tax-Deferral Edge (Surviving)
FD: Interest taxed annually on accrual at slab rate. Outflow drains compounding base.
Gilt Fund: Tax only at redemption. Full amount compounds for 3-5 years.
For 30%-slab over 5 years on ₹10L: gilt fund tax-deferral generates ~₹28K extra vs FD with identical 7% return. Modest but real.
NRI
30% TDS (or 20% under DTAA) on gilt fund capital gains. File ITR for DTAA benefit or refund. Form 10F + tax residency certificate required.
vs Bank FD (2-3 yr)
| Feature | Gilt | 2-3 yr FD |
|---|---|---|
| Returns | 6-15% variable | 6.40-6.60% locked |
| Capital Guarantee | No | Yes (DICGC ≤ ₹5L) |
| Liquidity | Anytime at NAV | Penalty 0.5-1% |
| Tax Timing | At redemption | Annually |
vs PPF (15-yr Lock-in)
| Feature | Gilt | PPF |
|---|---|---|
| Rate | Variable | 7.1% guaranteed |
| Lock-in | None | 15 yr |
| Tax | Slab on gains | EEE (tax-free) |
| Annual Cap | None | ₹1.5L |
| Section 80C | No | Yes |
Complementary strategy: max out PPF (₹1.5L/yr) for tax-free base, then use gilt funds for additional high-quality debt above this limit.
vs Corporate Bond Fund
| Feature | Gilt | Corp Bond |
|---|---|---|
| Credit | 100% Sovereign | AAA & AA+ corp |
| Yield | Lower | +30-80 bps |
| Credit Risk | ~Zero | Low |
| Rate Risk | High | Moderate |

Fund Selection, the Four Strategies, and Six Common Mistakes
How to choose between funds (expense ratio, duration consistency, AMC reputation), four tactical strategies (core-satellite, SIP, rate cycle, tax harvesting), and the six mistakes that turn rate-cycle volatility into permanent losses.
Part III · Page 8
Selection Criteria
Choose Regular or 10-Yr Constant
Regular: manager-flex, moderate risk, 3-5 yr horizon. 10-yr Constant: mechanical, high volatility, 5-7+ yr horizon with strong rate-cut conviction.
Direct Plan < 0.30%
Always Direct via AMC website, Coin, Kuvera, MF Utility. Over 10 yr on ₹10L at 7%: ₹1.6L difference between Direct and Regular.
Consistency: 3-5 yr Rolling
Top quartile gilt funds beat category over 3-5 yr rolling periods. Watch consistency, not 1-year wonders. Check Value Research / Morningstar.
AMC Reputation + AUM
Tier-1 debt AMCs (HDFC, ICICI Pru, SBI, Axis, Kotak). AUM ₹100 cr - ₹10,000 cr sweet spot. Long fund manager tenure indicates consistency.
Four Strategies
Core-Satellite Allocation
70% core (FD/PPF/Short) + 30% satellite (15% Gilt + 15% Corp Bond). ₹20L example: ₹14L core + ₹3L Gilt + ₹3L Corp Bond.
SIP Rate Averaging
₹25K/month for 12 months instead of ₹3L lump sum. Smooths timing risk. Captures opportunities across rate movements.
Tactical Rate Cycle Play
Accumulate when repo >6%, hold during cutting cycle, book profits when repo <5%. Feb 2026 at 5.25%: late-cycle, limit new entry.
Tax-Efficient Harvesting
Realise gilt fund losses during rate hikes to offset capital gains elsewhere. STCL offsets LTCG. Reinvest immediately (no wash-sale rule in India).
Six Common Mistakes
Treating Like FDs
"Government fund = guaranteed." Reality: NAV fluctuates daily. Negative returns possible short-term.
Panic-Selling at 5% Dips
Rate cycles reverse over 2-4 years. Selling locks in paper loss. Wait for cycle.
Chasing Past Returns
"Fund gave 15% in 2025." That came from falling rates (non-repeatable). Future depends on future rate path, not past.
Ignoring Expense Ratio
Direct 0.2% vs Regular 1.0% = ₹1.6L gap over 10 yr on ₹10L. Always Direct.
Wrong Time Horizon
Money needed in 1 year + 10-yr Constant Duration = forced loss-booking. Match horizon to fund type.
Ignoring Post-April 2023 Tax
Assumption: "long-term gains taxed favourably." Reality: slab rate always. Recalculate post-tax returns.
Feb 2026 Position Recommendation
| Status | Action |
|---|---|
| Hold from 2024 | HOLD |
| New entry, 5+ yr | Use STP, 5-10% of debt |
| New entry, 3 yr | Prefer Corporate Bond / FD |
Part IV
The Verdict
Sovereign safety. Rate-driven volatility. Match purpose precisely.
Part IV: The Verdict · Page 10
30-Second Summary
Gilt Funds separate the two engines of debt risk — credit and rate — by eliminating one (sovereign backing) and concentrating the other (rate sensitivity). They are precision instruments for duration positioning and high-quality debt allocation, not FD substitutes. SEBI's two subcategories give you the choice: regular gilt for manager-flex strategic allocation; 10-yr constant duration for high-conviction tactical bets.
Feb 2026: late-cycle position. RBI at 5.25% after 125 bps cuts during 2025. Most rate-cut gains captured. New entry should be staged (STP/SIP), horizon-matched (3-5+ years), and limited (5-10% of debt). Tax under Section 50AA is identical to FDs — slab rate always for post-April 2023 units. The only surviving structural edge is tax deferral, modest at 0.3-0.5% per year for 30%-slab investors over 5+ years. Direct plans (0.10-0.30%) versus Regular (0.50-0.80%) is the single largest leverage point.
"Gilt Funds are neither inherently better nor worse than other debt instruments — they are precise tools within a portfolio. Better than FDs for long-term sovereign-quality allocation with rate-volatility tolerance; worse than FDs for short-term stability and guaranteed outcomes. Better than corporate bonds for zero credit risk; worse than PPF for tax-free long-term savings. Understand what risk they remove and what they retain — and they serve their role well."

Key Terms & Definitions
Gilt Fund
A SEBI-regulated open-ended debt mutual fund mandated to invest at least 80% in Government of India securities (G-Secs) and State Development Loans (SDLs). Eliminates credit risk while concentrating interest rate risk.
Macaulay Duration
The weighted average time (in years) until you receive all cash flows from a bond. SEBI's category-defining metric. Acts like a rubber band's resting length — longer band stretches and contracts more dramatically when rates change.
Modified Duration
The percentage change in NAV per 1% change in interest rates. Derived from Macaulay duration. For a 7-year Macaulay fund at 7% YTM, Modified Duration ≈ 6.5-7.0 — your sensitivity dial.
10-Year Constant Duration
A SEBI subcategory where the gilt fund maintains portfolio Macaulay duration always around 10 years via mechanical rebalancing. Higher volatility than regular gilt funds; suitable only for high-conviction long-horizon tactical bets.
Section 50AA
Finance Act 2023 provision: for units of debt mutual funds (including gilt) bought on or after April 1, 2023, all gains are taxed at slab rate regardless of holding period. Eliminated the LTCG advantage gilt funds previously enjoyed.
Tax-Deferral Edge
The structural advantage gilt funds retain over FDs at identical slab tax rates: FD interest taxed annually on accrual; gilt fund gains taxed only at redemption. Worth ~0.3-0.5% per year for 30%-slab investors over 5+ years.
