A jeweller holds 180 days of gold inventory, half of it funded by gold metal loans. If gold rises 10%, what happens to its reported margin, its cash flow and its debt, and is the earnings jump worth paying for?

Reported EBITDA jumps about Rs 252 crore, 28%, and profit after tax about 48%, but none of it is recurring and none of it is cash. The owned half of the gold produces a one-time gain; the borrowed half is offset by the larger gold debt. Restocking at higher prices absorbs the cash, and debt rises about Rs 503 crore. Pay for the gain once, about Rs 189 crore after tax, not 25 times.

If you borrow a neighbour's bag of rice and must return a bag of rice, a rise in rice prices makes your bag worth more but your debt bigger by the same amount. A gold metal loanA loan of physical gold from a bank, repaid in the same weight of gold plus a fee, so the rupee size of the debt moves with the gold price. hedges itself: when gold rises, the gold held and the gold owed rise together. So only the owned half of Swarnatula's inventory, about Rs 2,515 crore, gains from a 10% rise: about Rs 252 crore.

The gain reaches the income statement through cost of sales: jewellery is priced at today's gold rate, but the gold in it was bought at the old price, so for about six months, the time it takes the old stock to sell, margins look wider. EBITDA rises from Rs 900 crore to about Rs 1152 crore, up 28%, and profit after tax from Rs 390 crore to about Rs 579 crore, up 48%, because interest and depreciation do not change.

Cash tells a different story. To keep the shelves full, Swarnatula must buy replacement gold at 10% higher prices, so the owned half now ties up about Rs 252 crore more rupees: the profit is converted into inventory, not cash. And the gold metal loans are now worth about Rs 252 crore more in rupees. Total debt, gold and rupee loans together, rises from about Rs 4,015 crore to about Rs 4,518 crore.

Only once. A one-time inventory gain is worth its after-tax amount, about Rs 189 crore, not a multiple of it, because it will not recur next year. At 25 times, the market cap before the rise was about Rs 9,750 crore. Capitalising the boosted profit at 25 times would imply about Rs 14,466 crore; adding the gain once gives about Rs 9,939 crore. The difference, about Rs 4,527 crore, is value that does not exist.

The symmetry is the warning. When gold falls 10%, the same unhedged half produces a one-time loss and the margin looks collapsed, which can make a sound business look broken. A good analyst strips inventory gains and losses out of margins in both directions, reports underlying EBITDA alongside the reported figure, and asks management what share of inventory it hedges and why. The limitation here is the simplifying assumption that underlying EBITDA does not move; in practice higher gold prices also change how many grams customers buy.
