A comprehensive deep-dive into India's only physical gas exchange — its business model, financials, valuation, and what's next as India races toward a gas-based economy.
IGX is India's only physical delivery-based natural gas exchange. It trades re-gasified LNG (imported) and domestically produced gas across multiple price segments.
Re-gasified Liquefied Natural Gas — imported LNG that arrives at terminals (Dahej, Hazira, Dabhol, Dhamra, Kochi, Chhara etc.), gets regasified, and sold on the exchange at market-discovered prices. This is the largest volume segment.
Gas produced by RIL, ONGC, Vedanta, HOEC from KG-D6 and other fields. Sellers have marketing & pricing freedom under MoPNG's August 2021 notification — they can sell directly on IGX at market-discovered prices.
Government-administered APM gas sold through special auctions at a ceiling price. Currently at $9.72/MMBtu. IGX has conducted 150+ such auctions, trading 100 lakh MMBtu (~2.5 BCM). Priority: CGD companies → fertilizer → power → others.
LNG transported by trucks — not pipelines. Serves areas not connected to the national grid. Contracts at Dahej, Hazira, Chhara, and Kochi. Daily, fortnightly & monthly contracts available.
IGX offers two main contract structures — Fixed Price contracts (price agreed upfront) and Index-Linked Long Duration Contracts (price floats with a benchmark index).
| Contract Type | Tenor | Trading Window | Price Basis | Min Lot |
|---|---|---|---|---|
| Intraday | Same day | Day D itself | Fixed, auction | 50 MMBtu/d |
| Day-Ahead | 1 Gas Day | D-1 | Fixed, auction | 50 MMBtu/d |
| Daily | 1 Gas Day | D-9 to D-4 | Fixed, auction | 50 MMBtu/d |
| Weekday / Weekly | 5 / 7 Gas Days | Up to D-4 | Fixed, auction | 50 MMBtu/d |
| Fortnightly | 13–16 Gas Days | Up to D-4 | Fixed, auction | 50 MMBtu/d |
| Monthly | Calendar Month | 12 contracts any day | Fixed, auction | 50 MMBtu/d |
| Balance of Month | Rest of month | 1st to 3d before EoM | Fixed, auction | 50 MMBtu/d |
| 3-Month (Index) | 3 Months | 4 rolling contracts | GIXI / JKM / WIM / Brent | 50 MMBtu/d |
| 6-Month (Index) | 6 Months | 1 rolling contract | GIXI / JKM / WIM / Brent | 50 MMBtu/d |
For 3-month and 6-month contracts, the final settlement price is linked to a benchmark — not fixed at trade time. Four benchmarks: GIXI (IGX's own domestic price index), JKM (Platts Japan-Korea Marker), WIM (Platts West India Marker), and Dated Brent. This allows buyers and sellers to hedge against international gas price movements without needing long-term bilateral contracts.
Power Contracts (monthly, fortnightly, weekly) for gas-based power plants. Flexible Contracts (monthly, fortnightly) for buyers needing quantity flexibility. Available at Dahej, Hazira, Dabhol, Chhara, Mhaskal, Kochi, Dhamra.
* Trading hours: 10:00 AM – 2:00 PM IST. Max 8 daily contracts on any trade date. Days = business days.
IGX operates across 6 regional gas hubs with 20+ delivery points, covering all major LNG terminals and domestic gas field offtake points in India.
Each delivery point is a physical location on India's gas pipeline network or LNG terminal. When you buy gas on IGX, you specify the delivery point — that's where the gas is picked up or injected into the pipeline. Prices vary by hub, reflecting regional demand-supply dynamics. This is what makes IGX a physical delivery exchange, not just a paper market.
The question every analyst asks: why can't a fertiliser plant just call ONGC and buy gas directly? Six structural advantages of the exchange over bilateral deals.
Bilateral markets are opaque and relationship-dependent. On IGX, prices are discovered daily through a competitive double-sided auction with all bids visible. Nobody gets a sweetheart deal.
IGX acts as the central counterparty — it guarantees settlement to both buyer and seller. Central clearing eliminates credit risk entirely. Payment happens the next day after delivery.
Bilateral contracts are typically 1–25 year deals with take-or-pay clauses. On IGX, you can buy gas for tomorrow, next week, or next month — no long-term commitment. A power plant facing an outage can sell excess gas the same day.
On IGX, 200+ clients and 50+ members across India are visible on one platform. A seller in KG Basin can sell to a buyer in Hazira without knowing them personally.
Transaction fees are ₹4/MMBtu (ex-hub) or ₹6/MMBtu (delivered) — transparent and fixed. No hidden costs, no lawyers, no long negotiations.
Even companies that do bilateral deals use IGX prices (GIXI index) as a reference for pricing long-term contracts. The exchange creates the price signal for the entire gas market.
A gas trade on IGX goes through six distinct stages, from bid submission to physical gas flow through the pipeline.
Ex-Hub: Buyer picks up gas at the delivery point hub and arranges their own pipeline transportation. Margin: 25% of trade value (weekly/monthly).
Delivered: IGX facilitates delivery to buyer's doorstep including pipeline transportation. Higher margin (25% + 102% of estimated ship-or-pay margin) but buyer doesn't manage pipeline logistics.
All buy bids ranked highest to lowest; all sell bids lowest to highest. The system finds the price where cumulative buy volume = cumulative sell volume — the Market Clearing Price (MCP). Every matched buyer pays this same price; every matched seller receives this same price. This is the fairest possible mechanism.
GIXI (Gas IndeX of India) is India's first and only domestic gas price benchmark — India's equivalent of Henry Hub or TTF, in its early innings. The most important thing IGX has built beyond trading volumes.
Volume-weighted average price of all gas traded on IGX at each delivery hub, excluding domestic ceiling price gas and ssLNG. Calculated daily and published publicly on the IGX website.
Regional: GIXI West, GIXI East, GIXI South, GIXI Central — each hub gets its own price reflecting local demand-supply.
Monthly: Named GIXI-Jan26, GIXI-Feb26 etc. — cumulative monthly average. Settlement reference for index-linked long duration contracts.
| Hub / Period | ₹/MMBtu | $/MMBtu |
|---|---|---|
| GIXI West — Nov-25 | 1,028 | $11.6 |
| GIXI East — Nov-25 | 939 | $10.6 |
| GIXI West — Dec-25 | 1,025 | $11.6 ▲5% |
| GIXI West Jan-26 / Nov-26 | 1,020 | $11.5 |
| Hazira (Nov-25) | 932 | $10.5 |
| Dahej (Nov-25) | 976 | $11.0 |

IGX is the central counterparty for every trade — guaranteeing performance to both buyer and seller. It collects margins from both parties before and during the life of each contract.
| Contract Type | Buyer Margin | Seller Margin | Pay-out (Seller) |
|---|---|---|---|
| Weekly / Monthly (Ex-Hub) | 25% of trade value by T+1 | 15% of trade value by T+1 | D+2 (after proof of delivery) |
| Weekly / Monthly (Delivered) | 25% + 102% of ship-or-pay margin (cash) by T+1 | 15% by T+1 | D+2 |
| Day-Ahead / Daily | 100% of trade value + tax on Trade Day | 15% on Trade Day | D+2 |
| 3-Month Index | CRM: 15% (~14 Gas Days). PSM Ex-Hub: 26% (~24 Gas Days) | CRM: 15% | Fortnight End +6 |
| 6-Month Index | CRM: 10% (~18 Gas Days). PSM Ex-Hub: 13% (~24 Gas Days) | CRM: 10% | Fortnight End +6 |
Ship-or-Pay Margin: For delivered contracts, buyer pays 102% of estimated ship-or-pay charge — protects against buyers refusing to pay pipeline charges.
Proof of Delivery: Sellers are paid only after proof of delivery is submitted — protects buyers against non-delivery.
Cash vs Non-Cash: IGX accepts government securities, bank guarantees etc. as non-cash margin — reduces working capital burden while maintaining risk coverage.
IGX has a three-tier access structure. Any entity that consumes or produces gas in India can potentially participate.
1. Write to [email protected] expressing interest. 2. Provide documentation (KYC, board resolution, audited financials). 3. Pay registration and security deposit fees. 4. Onboard on Trader Workstation (TWS) or set up API. Start trading.
Sellers (35+ on IGX): ONGC, RIL (KG-D6), Vedanta, HOEC, GAIL, Shell, BP, Total, Torrent Gas, IOC, BPCL.
Buyers (190+ on IGX): CGD companies (IGL, MGL, Adani Gas, Torrent, CUGL) — ~40% of volume. Fertiliser plants (Rashtriya Chemicals, GSFC, Coromandel). Power companies (NTPC, GMR). Industrial consumers (Saint-Gobain, JSW Steel, Kajaria, Aditya Birla, Hindalco). Paper, petrochemical and textile companies.
IGX has grown from near-zero in FY21 to handling 1 BCM of gas in just H1 FY26. The volume trajectory is steep, though Middle East supply disruptions created headwinds in Q4FY26.
Quarterly volume trajectory (MMSCMD):
* Source: IGX Nov-2025 presentation. Q4FY26 = 18.6 Mn MMBtu (from IEX concall). Middle East supply disruptions (Strait of Hormuz) impacted Q4FY26 and early FY27 volumes.
IGX earns revenue primarily through transaction fees, membership fees, and data services. The fee structure is elegantly simple and fully transparent.
FY26: ~76.8 Mn MMBtu traded. Assuming ~60% ex-hub (₹4) and ~40% delivered (₹6): Gross notional ≈ ₹368 Cr. But IGX's actual reported revenue is much lower (₹48.8 Cr in FY25) because the company reports net transaction fees after clearing costs. The business model is asset-light — once volumes scale, operating leverage kicks in dramatically.
IGX is a profitable, growing business. FY26 PAT of ₹41.9 Cr on revenue of ~₹48.8 Cr (FY25 data) implies NPM of 63%+ — exchange economics at work.
| Metric (₹ Cr) | FY23 | FY24 | FY25 | FY26 (Implied) |
|---|---|---|---|---|
| Revenue | 42.7 | 34.8 | 48.8 | ~66 est. |
| Gross Margin % | 100% | 100% | 100% | 100% |
| Employee Expenses | 10.3 | 9.8 | 10.7 | ~12 |
| Other Expenses | 11.4 | 10.8 | 12.0 | ~13 |
| EBITDA | 21.0 | 14.2 | 26.1 | ~41 |
| EBITDA Margin % | 49.2% | 40.8% | 53.5% | ~62% |
| Other Income (Treasury) | 19.3 | 19.8 | 20.3 | ~22 |
| D&A | 2.2 | 2.7 | 5.2 | ~5 |
| PBT | 37.6 | 30.7 | 40.5 | ~57 |
| PBT Margin % | 88.1% | 88.2% | 83.0% | ~86% |
| Tax | 9.6 | 7.7 | 9.5 | ~15 |
| PAT | 28.0 | 23.0 | 31.0 | 41.9 |
| NPM % | 65.6% | 66.1% | 63.5% | ~63% |
| EPS (₹) | 3.79 | 3.11 | 4.19 | ~5.65 |
Treasury income is big: Other Income (₹19–20 Cr) is nearly as large as EBITDA. IGX earns investment income on margin money collected from members — a structural feature of exchanges.
FY24 dip was temporary: Revenue fell from ₹42.7 Cr to ₹34.8 Cr due to global LNG price spikes dampening demand. FY25 and FY26 showed sharp recovery.
Extreme operating leverage: Fixed cost base is ~₹25 Cr. Every incremental rupee of revenue flows almost entirely to EBITDA at maturity.
IGX's shareholding as of 31 March 2025 is strategically constructed — IEX as promoter, NSE as financial partner, and five large gas companies as strategic investors.
Total shares: 7,50,00,000 (7.5 Crore). Source: IGX document 31/03/2025.
PNGRB's Gas Exchange Regulations 2020 require that no single promoter can hold more than 26% stake in a gas exchange once fully operational — to ensure IGX remains a neutral, industry-owned institution.
IEX currently holds 47.28% — almost double the 26% ceiling. PNGRB has given IEX a deadline of December 31, 2026 to dilute its stake. This will happen via secondary sale to new investors or via an IPO — both are now in motion.
For investors: This mandated dilution is a positive catalyst — it brings a market price for IGX shares and unlocks value for all shareholders including ONGC, IOC, GAIL, and Adani Gas.
As per the IEX Q4FY26 conference call (April 2026): "IGX IPO process — we have initiated the process... it is progressing well."
The April 2026 IEX earnings call provided significant colour on the near-term headwinds and long-term growth drivers for IGX.
1. Domestic gas market deepening: India's gas consumption is growing — CGD network expansion, gas-based power generation, and industrial gas usage are all expanding the addressable market.
2. India becoming a gas hub: The government envisions India as a natural gas trading hub in Asia. GIXI index and PNGRB backing put IGX at the centre of this ambition.
3. Gas derivatives / futures: Once gas futures are permitted, GIXI becomes the settlement benchmark and IGX becomes the physical delivery leg — a massive volume and revenue opportunity.
4. International cooperations: MOUs with S&P Global (Jan 2024), GSPC & GIFT City, EEX/GIZ, CEGH, HP, Crown LNG, Prisma European Capacity Platform — building international connectivity and credibility.
IGX is pre-IPO, so there is no public market price. We construct a valuation range using P/E multiples on FY26 PAT (₹41.9 Cr confirmed) and FY27 estimates.
PAT FY26 = ₹41.9 Cr (confirmed). Total shares = 7.5 Cr. FY26 EPS = ₹5.59/share.
FY27E PAT ≈ ₹50 Cr (assuming ~20% growth). FY27E EPS ≈ ₹6.67/share.
Arguments for 40–50x: Volume CAGR of 80%+ since inception. 100% gross margins with extreme operating leverage. GIXI index = long-term moat. Only gas exchange in India — no competition. Gas is the transition fuel for India's net-zero journey.
Arguments for 25–35x: Middle East LNG supply disruption risk. Volumes still small vs India's total gas consumption. Regulatory dependence on PNGRB. No futures/derivatives yet.
Our view: 40x P/E on FY27E PAT (₹2,000 Cr market cap, ~₹267/share) is a reasonable base case for pre-IPO evaluation.
