A Government Security (G-Sec) is a tradable instrument issued by the Central or State Government acknowledging its debt obligation. The RBI issues G-Secs on behalf of the Government under the RBI Act, 1934.
G-Secs carry practically zero default risk as they are backed by the sovereign guarantee of the Government of India, making them risk-free gilt-edged instruments.
| Term | Meaning | Exam Relevance |
|---|---|---|
| Gilt-edged | High-grade, near-zero default risk securities | Often asked as T/F — "G-Secs are called gilt-edged because they are printed on gold paper" (FALSE) |
| Coupon | Fixed interest rate on the face value, paid semi-annually | Coupon ≠ Yield — important distinction |
| Yield | Effective return to investor; moves inversely with price | Inverse price-yield relationship is a classic trap |
| Face Value | Value at which G-Sec is redeemed at maturity | Minimum auction bid = ₹10,000 |
| SGL Account | Subsidiary General Ledger — account for holding G-Secs with RBI | Custodian mechanism; banks maintain SGL accounts |
| WMA | Ways and Means Advances — short-term credit by RBI to GoI | Distinct from G-Sec issuance; interest-bearing overdraft |
G-Secs are also called Gilts. The term "gilt-edged" originally referred to certificates with gold-coloured edges indicating top-quality, sovereign-backed debt instruments.
UPSC often tests the issuer distinction: Central Government issues both T-Bills and dated G-Secs, while State Governments issue only dated securities called State Development Loans (SDLs). T-Bills are not issued by state governments.
| Category | Instrument | Issuer | Maturity | Key Feature |
|---|---|---|---|---|
| Short-Term | Treasury Bills (T-Bills) | Central Govt only | 91-day, 182-day, 364-day | Zero coupon; issued at discount; redeemed at face value |
| Cash Management Bills (CMBs) | Central Govt only | <91 days | Introduced in 2010; for temporary cash-flow mismatches | |
| Long-Term | Dated Government Securities | Central Govt | 5–40 years | Fixed coupon, paid semi-annually; most actively traded |
| State Development Loans (SDLs) | State Govts only | Usually 10 years | Annual borrowing under state fiscal management | |
| Floating Rate Bonds (FRBs) | Central Govt | Varies | Coupon linked to benchmark (e.g., 91-day T-Bill yield) | |
| Inflation Indexed Bonds (IIBs) | Central Govt | Varies | Principal indexed to CPI/WPI; hedge against inflation | |
| Sovereign Green Bonds (SGrBs) | Central Govt | Varies | Proceeds for green/climate projects; included in FAR (2026) |
"T-Bills carry no interest" — TRUE (they are zero coupon) but "T-Bills give no return" — FALSE. The return is the difference between the discounted issue price and the face value at redemption.
STRIPS = Separate Trading of Registered Interest and Principal of Securities. They allow the coupon and principal of a G-Sec to be traded separately, creating zero-coupon instruments from coupon-bearing bonds.
India became the 25th market to enter the JP Morgan GBI-EM index when it debuted in June 2024. India's bonds had the highest duration across the index at 7.03 years with an above-average yield to maturity of 7.09%.
| Institution | Role | Key Detail |
|---|---|---|
| RBI | Issuer, Debt Manager, Custodian | Issues G-Secs on behalf of Central Govt; manages public debt under RBI Act, 1934; manages SGL accounts; conducts auctions via E-Kuber |
| E-Kuber | Primary market auction platform | RBI's Core Banking Solution (CBS) platform; auctions held every Friday for T+1 settlement; members include banks, PDs, insurers, provident funds |
| NDS-OM | Secondary market trading platform | Anonymous, electronic order-matching; operated by RBI; OTC trades must be reported within 15 minutes; trading hours 9 AM – 5 PM (Mon–Fri) |
| CCIL (Clearing Corporation of India Ltd.) | Clearing & settlement | Central Counterparty (CCP) for all G-Sec trades; guarantees settlement on T+1 basis (T+2 for FPIs); interposes itself as buyer to every seller |
| Primary Dealers (PDs) | Market-makers & underwriters | Must underwrite G-Sec auctions; provide two-way quotes; examples: SBI DFHI, PNB Gilts, STCI PD; introduced in 1994 |
| RBI Retail Direct Scheme | Retail investor access | Launched 2021; retail investors open Retail Direct Gilt (RDG) accounts directly with RBI; access both primary and secondary markets |
| SEBI-registered Brokers | Expanded retail access | Since Feb 2025, non-bank brokers with SEBI registration can access NDS-OM for retail clients (new addition) |
UPSC frequently asks about CCIL's role. Key point: CCIL acts as a Central Counterparty (CCP) — it becomes the buyer to every seller and seller to every buyer, guaranteeing settlement. It does NOT regulate G-Secs (that's RBI and SEBI).
The day-count convention for Central Government securities is 30/360 (30 days per month, 360 days per year). Auction settlement is on T+1 basis for most participants.
| Route | Full Form | Investment Limit | Key Feature | Who Benefits |
|---|---|---|---|---|
| FAR | Fully Accessible Route | Uncapped (no investment limit on FAR-designated securities) | Introduced 2020; specified G-Secs freely accessible to all non-residents without restrictions; basis for JP Morgan & Bloomberg index inclusion | Global institutional investors, index funds |
| General Route | — | 6% of outstanding Central G-Sec stock | Subject to earlier restrictions (short-term, concentration, security-wise limits) — all THREE removed post June 2026 reforms | FPIs, FIIs seeking active allocation |
| SGS Limit | State Government Securities | 2% of outstanding State G-Sec stock | Separate limit for SDLs; 'General' & 'Long-Term' sub-categories merged into one post-2026 | FPIs investing in state bonds |
| VRR | Voluntary Retention Route | Previously separate; merged with General Route limits from April 1, 2026 | Required FPIs to retain minimum % in India; now subsumed into General Route framework | Long-term FPIs preferring stability |
| Corporate Bond Limit | — | 15% of outstanding corporate bond stock | Separate from G-Sec limits; unchanged | FPIs in corporate debt |
FPI investment limits (General Route): G-Secs = 6% · SGSs (SDLs) = 2% · Corporate Bonds = 15% of outstanding stock. These numbers are directly asked in Prelims MCQs. The overall limits remain unchanged even after the June 2026 reforms.
FPI investments in G-Secs under FAR settle on T+2 basis (vs T+1 for domestic players) through CCIL. The JP Morgan GBI-EM includes 29 Indian G-Secs under FAR — all maturing after December 31, 2026.
| Instrument | FPI Limit (% of Outstanding) | Absolute Limit (FY27) |
|---|---|---|
| Central Government Securities (G-Secs) | 6% | Higher half: ₹16.32 lakh crore aggregate |
| State Government Securities (SDLs/SGSs) | 2% | Full increase to 'General' sub-category |
| Corporate Bonds | 15% | Additional ₹3,30,464 crore for FY27 |
| Credit Default Swaps (CDS) sold by FPIs | 5% of corporate bond stock | Notional amount limit |
Total FPI debt investment limit in India set to increase from ₹14,70,655 crore to ₹15,51,646 crore for H1 FY27 (April–September 2026) and further to ₹16,32,640 crore for H2 FY27 (October 2026–March 2027).
India's G-Sec market at ₹112+ lakh crore is one of the largest sovereign bond markets among emerging economies. FPIs holding only 3.34% shows significant headroom for global participation — one of the core rationales for the June 2026 reforms.
The Ministry of Finance announced a comprehensive package on June 5, 2026 to deepen the G-Sec market and attract long-term foreign capital, comprising four pillars:
| Reform Pillar | Old Regime | New Regime (Post June 2026) |
|---|---|---|
| FPI Tax on G-Sec Interest | Taxed at 20% under Section 210, IT Act 2025 | Fully exempt via Income-tax (Amendment) Ordinance, 2026 — Schedule IV Entry 13D |
| FPI Tax on Capital Gains from G-Secs | STCG at 30%; LTCG at 12.5% | Fully exempt (sale, transfer, exchange, redemption) — effective April 1, 2026 |
| FAR Coverage | Selected existing dated securities | Expanded to new issuances in 15-yr, 30-yr, 40-yr tenors + Sovereign Green Bonds (SGrBs) in FAR-eligible tenors |
| Short-term investment limit | FPIs could not exceed 20% of holdings in short-term G-Secs under General Route | Removed |
| Concentration limit | Max % holding in any single G-Sec restricted | Removed |
| Security-wise investment limit | Cap on FPI investment per individual security | Removed |
| General + Long-Term categories | Two separate sub-categories for FPI G-Sec investments | Merged into single investment limit; VRR also subsumed |
| BIS Tax Treatment | Bank for International Settlements taxed on G-Sec income | Fully exempt (same as FII exemption) — Schedule IV Entry 13E |
| PROI equity access | Limited to NRIs/OCIs via registration | Extended to all individual Persons Resident Outside India (PROIs) via FEMA (Non-Debt Instruments) Third Amendment Rules, 2026 |
The Bank for International Settlements (BIS), headquartered in Basel, Switzerland (est. 1930), has also been granted the same G-Sec tax exemption under the 2026 ordinance. BIS is the "central bank of central banks." This is likely a UPSC trap to confuse with other international institutions.
The ordinance inserts two new entries in Schedule IV of the IT Act, 2025: Entry 13D (FII/FPI exemption) and Entry 13E (BIS exemption). Effective date: April 1, 2026 — not the date of the ordinance (June 5, 2026). This backdating distinction may be tested.
| Linked Concept | Connection to G-Secs | How to Recall |
|---|---|---|
| Open Market Operations (OMO) | RBI buys/sells G-Secs to manage money supply; buying G-Secs injects liquidity; selling absorbs liquidity | OMO = RBI's main instrument of liquidity management using G-Secs |
| Fiscal Deficit | Government borrows via G-Secs to finance its fiscal deficit; G-Sec issuance = government borrowing | Budget gap → financed by G-Sec auctions via RBI on E-Kuber |
| Yield Curve | G-Sec yields across different maturities form the sovereign yield curve — benchmark for all other interest rates in India | Rising short-term yields + flat long-term = inverted curve (recession signal) |
| SLR (Statutory Liquidity Ratio) | Banks mandatorily hold G-Secs as part of their SLR requirement — they are the primary domestic buyers | SLR = captive demand for G-Secs from banks |
| CAD (Current Account Deficit) | Greater FPI inflows via G-Secs help finance CAD; reduces pressure on forex reserves | More FPI in G-Secs → more dollar supply → rupee stabilisation |
| Rupee Exchange Rate | FPI G-Sec inflows increase dollar supply in India → strengthens rupee; outflows weaken rupee | June 2026 reforms partly aimed at supporting a rupee that weakened 6%+ due to FPI equity outflows |
| Monetary Policy Transmission | G-Sec yields reflect market expectations of future policy rates; RBI's repo rate directly influences short-end G-Sec yields | Repo rate ↑ → short-term G-Sec yields ↑ (usually) |
| Sovereign Green Bonds | SGrBs are G-Secs with proceeds ring-fenced for green/climate projects — now included in FAR and eligible for index inclusion | India issued first SGrBs in FY23; now FAR-eligible post June 2026 |
India's forex reserves had declined from approximately $725 billion to $681 billion in early 2026. The June 2026 G-Sec reforms are explicitly aimed at increasing dollar inflows to stabilise the rupee and rebuild forex reserves.
UPSC often links G-Secs to monetary policy tools. Remember: OMO and Liquidity Adjustment Facility (LAF) both use G-Secs. In LAF, RBI conducts repo (banks pledge G-Secs to borrow from RBI) and reverse repo (RBI pledges G-Secs to borrow from banks).
The Ministry of Finance announced landmark G-Sec market reforms on June 5, 2026. The Income-tax (Amendment) Ordinance, 2026 grants full exemption from interest income and capital gains to FIIs/FPIs investing in Government Securities, effective April 1, 2026. The exemption covers all G-Sec income arising from interest, capital gains on sale, transfer, exchange, or redemption. The ordinance inserts Entries 13D and 13E into Schedule IV of the Income-tax Act, 2025.
The government expanded the Fully Accessible Route (FAR) to include new issuances in 15-year, 30-year, and 40-year Government Security tenors, as well as Sovereign Green Bonds (SGrBs) in FAR-eligible tenors. Simultaneously, three General Route restrictions — the short-term investment limit, concentration limit, and security-wise limit — were removed. The existing 'General' and 'Long-Term' FPI investment sub-categories were merged into a single limit. Overall caps remain: 6% for Central G-Secs and 2% for SGSs (SDLs).
The June 2026 tax exemptions have brightened prospects for Indian sovereign bonds' inclusion in Bloomberg's Global Aggregate Index — a flagship global bond benchmark far larger than the JP Morgan GBI-EM. Indian bonds' previous tax drag was the main barrier to Bloomberg Global Aggregate consideration. Prior to the reform, the effective post-tax yield on Indian G-Secs lagged comparable sovereign bond markets in Southeast Asia and the Middle East, most of which offer full or near-full tax exemptions to foreign investors.
RBI retained FPI investment percentage limits in G-Secs unchanged for FY 2026-27 at 6% (Central G-Secs), 2% (SGSs), 15% (Corporate Bonds). However, total absolute debt limit rose to ₹16.32 lakh crore for H2 FY27. Effective April 1, 2026, all investments under the Voluntary Retention Route (VRR) are subject to General Route limits — effectively merging VRR into the General Route framework.
India has witnessed record FPI equity outflows of over $26.4 billion so far in 2026 — already surpassing the full-year outflow of 2025. The rupee has weakened more than 6% in 2026. RBI's growth forecast for FY 2026–27 was trimmed to 6.6%. The June 2026 G-Sec reforms are partly a strategic response to this pressure — attracting stable, long-term bond investors (pension funds, sovereign wealth funds, insurance companies) to offset volatile equity FPI outflows.
The FEMA (Non-Debt Instruments) (Third Amendment) Rules, 2026 were notified by the DEA to expand equity access for individual Persons Resident Outside India (PROIs). The NRI/OCI facility was extended to all individual PROIs, allowing them to invest in listed Indian equity without SEBI registration. Individual investment ceiling and aggregate limits were both increased as part of this liberalisation.
The June 2026 G-Sec reforms are high-probability for UPSC 2026/2027 Prelims. Anchor your knowledge on: (1) the three removed General Route restrictions, (2) FAR expansion to 15/30/40 yr + SGrBs, (3) tax exemption effective date (April 1, 2026, not June 5), (4) overall 6%/2% limits unchanged, (5) BIS also included in exemption.
| Statement | Verdict | Reason / Correction |
|---|---|---|
| State governments issue Treasury Bills (T-Bills) | ❌ FALSE | Only the Central Government issues T-Bills. State governments issue only State Development Loans (SDLs) — dated securities only. |
| T-Bills are zero-coupon instruments | ✅ TRUE | T-Bills pay no periodic interest. They are issued at a discount and redeemed at face value. The return is the difference between issue price and face value. |
| FAR requires FPIs to stay within the 6% overall cap | ❌ FALSE | FAR-designated securities are outside the investment limits. FAR = Fully Accessible Route with no cap on specified securities. The 6% cap applies to the General Route only. |
| CCIL guarantees settlement of all G-Sec trades | ✅ TRUE | CCIL acts as Central Counterparty (CCP) and guarantees settlement of all OTC and NDS-OM G-Sec trades. |
| The June 2026 reform removed the 6% overall FPI investment limit in G-Secs | ❌ FALSE | The overall 6% limit remains unchanged. Only the three sub-restrictions within the General Route (short-term, concentration, security-wise limits) were removed. |
| RBI issues G-Secs on behalf of both Central and State Governments | ✅ TRUE | RBI is the banker and debt manager for both. State Government transactions are handled under agreements between RBI and state governments (all states except Sikkim as of last update). |
| India's inclusion in JP Morgan GBI-EM was announced in June 2024 | ❌ FALSE | Announced in September 2023; actual inclusion commenced in June 2024 (staggered at 1%/month). |
T-Bills have zero coupon (no periodic interest payment) but they do give a return — through discount to face value. A ₹95 T-Bill redeemed at ₹100 gives ₹5 return. UPSC has tested this as a statement to evaluate.
FAR = no investment limit on specified securities. General Route = 6% aggregate cap. FAR was the mechanism that made JP Morgan index inclusion possible. Do NOT confuse "Fully Accessible" with "no restrictions at all" — the securities must be explicitly designated as FAR securities by RBI.
The Income-tax (Amendment) Ordinance, 2026 was published in Gazette on June 5, 2026 but the tax exemption is effective from April 1, 2026. UPSC loves this type of date distinction. The effective date for the exemption is April 1 — not June 5.
The 6%/2%/15% limits are: 6% = Central Government Securities (G-Secs), 2% = State Government Securities (SGSs / SDLs), 15% = Corporate Bonds. Students often mix up SDLs with corporate bonds or think all debt securities have the same FPI limit.
G-Secs are called gilt-edged because they are high-grade, sovereign-backed instruments — NOT because they are printed on gold-edged paper. The term is metaphorical — "gilt" refers to golden quality (trustworthiness), not physical gold.
RBI manages State Government debt (SDLs) under agreements with state governments — not by statutory mandate alone. Notably, Sikkim did not have such an agreement with RBI (the only exception). This factoid has been tested.
