Ram Ratna Wires Limited

Who it hits first

• Copper miners (Hindustan Copper, Hindalco) face softer realisations
• Wire and cable makers (KEI, Polycab, Finolex, Ram Ratna) get input relief
• Smelters' treatment charges stay squeezed on concentrate shortage

Who may gain

• Cable makers expand margins as copper cost eases
• Electrical-equipment buyers gain on lower input pass-through later

When it plays out

Who it hits first

• Copper and aluminium wire and cable makers - Ram Ratna Wires and Precision Wires - see 500 to 570 basis points of gross-margin pressure before pass-through, plus a bigger working-capital bill
• Vehicle makers, cable makers and electrical equipment firms face higher metal costs with roughly a one-quarter lag
• Renewable and transmission project developers see capital cost inflation on cabling and structures

Who may gain

• National Aluminium is the cleanest winner - captive bauxite and captive power mean a 5.20% price rise lands almost entirely in profit at a 44% operating margin
• Hindalco gains on both metals; Hindustan Copper's revenue moves one-for-one with copper; Vedanta gains across copper, aluminium, zinc and silver
• Metal recyclers and scrap processors gain as high primary prices widen the scrap discount

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.
