Member story

Benchmark polished diamonds prices moved 17.5% over the past four weeks, the sharpest swing since Q1 FY27, as inventories abroad normalised and shipping schedules recovered. The move has quickly filtered into spot quotes at Kolkata, where dealers reported narrower spreads and thinner volumes through the week.

Credit conditions have helped. Working-capital spreads for E-Commerce borrowers narrowed by roughly 25 basis points, and corporate bond issuance from the sector reached $2.2 billion for the year to date, the highest in three years. Rating agencies have upgraded four issuers while downgrading none.

Key takeaways

  • Benchmark polished diamonds moved 17.5% in four weeks, the sharpest swing since Q1 FY27.
  • Importers with unhedged positions cut landed costs by up to 6.5%.
  • Forward premiums eased, making three-to-six month hedges more attractive.
  • The E-Commerce index outperformed the market by about two percentage points over the quarter.
  • Domestic producers' realisations fell 9%; two listed firms trimmed guidance.

What moved and why

On the other side of the ledger, producers are watching margins. Realisations for domestic E-Commerce suppliers fell 9% on the month, and two listed companies trimmed guidance in post-results calls. Management teams pointed to input cost relief as a partial offset, but warned that price competition would intensify.

Equity markets have taken a constructive view of the sector. The E-Commerce index gained 17.5% over the quarter, outpacing the broader market by about two percentage points, with the largest moves in names that disclosed order books extending beyond twelve months.

Global cues remain mixed. Demand data from USA came in softer than expected, while restocking in Brazil offered a counterweight. The net effect is a market that is range-bound in the near term but sensitive to any surprise in freight or policy.

“Margins, not prices, are the story. Input relief only helps those who can hold their own selling price.”

Priya Nambiar, Policy Editor

Winners, losers and margins

Physical premiums tell a similar story. Delivered premiums at Kolkata compressed by about $334 million per tonne equivalent, and buyers report that sellers are now willing to quote longer validity periods, a reversal from the short-fuse offers that dominated earlier in the year.

The immediate beneficiaries are importers who left positions unhedged. JSW Steel, which buys roughly 2,145 tonnes a quarter, said it had trimmed its landed cost by 6.5% since the start of the month and was deferring forward purchases in anticipation of further softness.

Positioning and hedging

For corporate buyers, the practical advice from risk consultants is to layer hedges rather than chase the move: cover 40 to 60 percent of the next two quarters at current levels, keep optionality for the remainder and revisit after the next inventory report.

Timeline of key events

  1. 13 Sep 2026
    Inventories normalise

    Stocks abroad rebuild after a long drawdown, easing spot tightness.

  2. 21 Sep 2026
    Spot softens

    Benchmark slides 6.5% in a week; dealers at Kolkata report thin volumes.

  3. 29 Sep 2026
    Guidance trimmed

    Two listed producers lower margin outlook in post-results calls.

  4. 7 Oct 2026
    Hedging surge

    Treasury desks extend hedge tenors as forward premiums ease.

  5. 15 Oct 2026
    Range established

    Prices consolidate; analysts debate the floor.

Strategists are less unanimous about what comes next. One brokerage raised its target for the sector on earnings upgrades, while another cut its rating citing valuations at 9% above the five-year average. The disagreement, one fund manager noted, is itself a sign that the trade is maturing.

Expert commentary

“The disagreement among analysts is the most useful data point this quarter: it says positioning is no longer one-sided.”

The range ahead

Currency is an important second driver. The rupee traded in a narrow band against the dollar, helped by steady inflows and a decline in crude, and forward premiums eased to levels that make hedging more attractive for importers with a three-to-six month horizon. Treasury heads say they are extending hedge tenors.

What it means for you

Importers

Layer hedges at 40 to 60 percent of the next two quarters; defer discretionary forward buys while spreads remain tight.

Producers

Protect realisations with index-linked contracts; use input-cost relief to fund working-capital discipline rather than price cuts.

Investors

Favour names with order books beyond twelve months and low net debt; be cautious where valuations already price in earnings upgrades.

Treasury teams

Extend hedge tenors while forward premiums are low and document the policy so decisions survive volatility.

Layering is the consensus advice: cover roughly half of near-term needs now and retain flexibility for the rest.
