The two natural gas chains

NATURALGAS is 1,250 mmBtu a lot and NATGASMINI 250 mmBtu, both quoted in rupees per mmBtu: a ₹1 move is worth ₹1250 a NATURALGAS lot and ₹250 a mini lot. Because the price is a few hundred rupees, a single rupee is a large share of it and the strikes sit close together.

Each monthly series is written on its own month's future, and the months can be far apart: on 27 October 2026 the expiring October future was near ₹253 while the November future, on which the next options are written, was near ₹288. The chain always shows the future its expiry is written on.

What moves the natural gas chain

MCX natural gas follows the US benchmark, so the weather outlook and the weekly US storage report, out on Thursday evenings India time, are the events its options price. Natural gas options carry some of the highest implied volatility on MCX — about 70% at the money on 27 October 2026.

MCX trades from 09:00 to 23:30, or to 23:55 while US clocks are on winter time (early November to mid-March), and on some equity holidays it opens for the evening session only. Most of natural gas's news lands in the Indian evening, and OIData's chain is live for all of it.
