Copper tops $14,000 a tonne to a two-month high and aluminium hits a six-week high as available LME stocks fall to about one day of world consumption

Who it hits first

• Indian copper and aluminium producers — Hindustan Copper, National Aluminium, Hindalco and Vedanta — sell at prices set by the London exchange while their mining and smelting costs barely move, so most of the price rise drops straight to profit.
• Wire and cable converters are hit from the other side. Copper is 95% of Ram Ratna Wires' cost, 90% of Precision Wires', 65% of Finolex Cables' and 55.6% of KEI's, so the same move that enriches the miners squeezes them.
• The squeeze is a shortage of metal you can actually collect, not just a price move: available LME copper has fallen to roughly one day of world consumption, so converters may struggle to source at any price.

Who may gain

• National Aluminium gains most cleanly because it mines its own bauxite and runs its own power stations, so a higher metal price meets an almost unchanged cost of production.
• Vedanta gains across several divisions at once — aluminium, copper and zinc all rose together.
• Gravita, which recycles metal scrap, sees the gap widen between the scrap it buys and the refined metal it sells, because scrap prices follow refined prices with a lag.
