What It Means
A spot exchange is a marketplace for buying and selling a physical commodity for near-immediate delivery, at today's prevailing price. A futures exchange, like MCX or NCDEX, instead trades standardized contracts that settle on a specified future date, at a price agreed today.
How It Works
India's spot commodity exchange history is a cautionary one: the National Spot Exchange Limited (NSEL), launched in 2008, was found in 2013 to have been running long-dated "paired contracts" that violated the settlement rules for genuine spot trades, and it defaulted on roughly ₹5,600 crore owed to investors. That episode is part of why futures exchanges like MCX and NCDEX, directly regulated by SEBI with clear margining and settlement rules, are where the vast majority of India's organized commodity trading now happens; standalone spot exchanges for retail participation never really recovered afterward.
