Contango

## The concept Contango describes a futures market where the futures price is higher than the spot (cash) price, and where longer-dated contracts cost more than nearer ones. It is the *normal* condition for many assets, because holding the underlying until delivery has costs — storage, insurance, and the interest (financing) tied up in it. Buyers of the future are effectively paying the seller to carry the asset, so the future trades at a premium. The opposite state, where futures trade *below* spot, is backwardation.

## The cost-of-carry logic For a financial asset, the fair futures price is roughly spot + financing cost − any income (like dividends). Because Indian interest rates are positive and most index constituents pay modest dividends, Nifty and Bank Nifty futures usually trade in mild contango — a small premium to spot that shrinks to zero as expiry nears (convergence). For commodities like crude or natural gas on the MCX, storage costs widen the contango further.

## Why traders care - The premium decays: a futures premium erodes toward expiry. Sellers of overpriced futures (or calendar-spread traders) try to capture this. - Roll cost: anyone holding a long position by rolling from the expiring contract to the next month in contango pays up each roll — a real drag for commodity ETFs and continuously-rolled positions. This is why some commodity funds underperform spot prices over time. - Sentiment read: an unusually steep contango can signal weak near-term demand or ample supply; a flip to backwardation often signals tight supply or strong spot demand.

## In the Indian market Watch the futures basis (futures minus spot) on the NSE for index and stock futures and on the MCX for commodities. A normal, gently positive basis is contango at work. Sudden moves in the basis — or a swing into backwardation in a commodity — are worth investigating, as they reflect changing carry costs, dividend expectations, or supply-demand stress rather than just the direction of price.
