MCX Microstructure: How India's Largest Commodity Exchange Actually Prices Gold and Silver

Why MCX Matters Beyond India

The Multi Commodity Exchange of India (MCX), headquartered in Mumbai, handles the majority of gold and silver derivatives trading volume in the world's second-largest gold consumer market. Its price discovery is not just an Indian-local phenomenon; because Indian physical premium is one of the more visible signals of Asian retail demand, MCX's daily behavior feeds into global gold market interpretation.

This piece walks through the specific microstructural features of MCX gold and silver contracts — trading hours, tick sizes, delivery mechanics, margin rules — and explains why each one shows up in the MCX premium data. Reading MCX premium data intelligently requires knowing what the underlying contract actually is.

Contract Specifications

Our MCX reading references the main 1 kg gold contract, converted to USD per troy ounce for premium calculation. This is the deepest liquidity pool and provides the cleanest signal, though the Mini and Micro contracts often trade at slightly different levels for retail participants due to spread and size effects.

Trading Hours and Their Consequences

MCX trades in two sessions: a morning session from 09:00 IST and an extended session running to 23:30 IST. The evening extension is deliberate — it overlaps with the London afternoon and the New York morning, allowing Indian participants to trade with global reference prices live. The Sunday-Friday schedule follows Indian business days.

This has direct consequences for MCX premium data. During the morning session before London opens, MCX prices are set by domestic supply, demand, and INR-USD expectations. Once London and New York are live, MCX prices react much more closely to global movements. A premium reading at 10:00 IST is a different kind of information than one at 22:00 IST — the earlier reading is more purely Indian; the later reading is more contaminated by global co-movement.

Margin and Position Limits

MCX gold margin is set by the exchange and typically ranges from 5% to 8% of contract value in normal conditions, higher during volatility. The margin regime is more retail-permissive than COMEX's — combined with the smaller Mini/Micro contract sizes, this means the retail participation share in MCX price discovery is higher than in most Western commodity futures markets.

Position limits are enforced by the Securities and Exchange Board of India (SEBI) and are meaningfully binding for large institutional participants. This shapes how index funds, mutual funds, and jewelry-industry hedgers structure their MCX activity — often spreading positions across multiple related contracts to stay within limits.

Physical Delivery Mechanism

Unlike COMEX, where most contracts are cash-settled or rolled before delivery, MCX gold contracts can be physically settled and often are. The delivery process runs through empanelled vaults and refiners. When a contract holder chooses to take delivery, the resulting gold is a 1 kg bar of at least 995 fineness, deliverable from the MCX-approved warehouse network.

The delivery-eligibility of MCX gold gives Indian jewelers and refiners a legitimate hedging and sourcing tool. It is one reason MCX prices track physical Indian gold demand more directly than a purely financial futures contract would. When jewelers hedge future inventory needs by going long MCX and taking delivery, they influence both the futures price and eventually the retail physical premium.

The Metals.dev MCX Data Path

Our MCX price reading does not come from scraping the MCX website directly. It comes through Metals.dev's mcx_gold and mcx_silver fields, which aggregate the primary MCX futures pricing. This has three practical implications:

Reading MCX Premium in Context

Several MCX-specific factors regularly show up in the premium series and are worth being aware of.

Session-of-day drift

The morning-session MCX price sometimes trades at a small premium or discount to what the London-hours session sets. This is normal microstructure and reflects local overnight positioning rather than a demand signal. Our daily-close-based premium series smooths over this, but intraday users of MCX data should not over-interpret morning readings.

Duty announcement days

As covered in our India-duty history piece, budget announcement days and other policy-driven duty changes produce visible steps in the MCX premium. These are policy events, not physical-demand events, and should be interpreted separately.

Rupee volatility days

On days when the INR moves against the USD by more than 0.5%, a meaningful share of any MCX premium move is currency, not gold. Cross-referencing with same-day INR-USD is essential for reading the MCX premium correctly. Our currency-effect guide describes the decomposition method.

Sudden liquidity events

MCX can occasionally see wider bid-ask spreads on the main contract, particularly during global holiday windows when London and New York are closed. During such windows, MCX premium data is thinner and less reliable. Cross-referencing volume alongside the premium reading helps identify these events.

What This Site Enables

The MCX card on our dashboard shows the current premium against COMEX. The /market/mcx page shows the historical premium series with the same normalization we apply to other markets. Because we take the daily settlement price rather than intraday snapshots, our MCX series primarily reflects end-of-day pricing and is more comparable to the equivalent close-of-day COMEX and LBMA readings.

Users interested in intraday MCX behavior should look at MCX's own market data feed. Users interested in the daily premium signal — is Indian physical demand tight or loose today — will find our aggregated series more useful.
