Benchmark polished diamonds prices moved 18.9% over the past four weeks, the sharpest swing since Q4 FY26, as inventories abroad normalised and shipping schedules recovered. The move has quickly filtered into spot quotes at Chennai, 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 $7.1 billion for the year to date, the highest in three years. Rating agencies have upgraded four issuers while downgrading none.
What moved and why
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 7.5% above the five-year average. The disagreement, one fund manager noted, is itself a sign that the trade is maturing.
On the other side of the ledger, producers are watching margins. Realisations for domestic E-Commerce suppliers fell 7.5% 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.
By the numbers
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.
“Margins, not prices, are the story. Input relief only helps those who can hold their own selling price.”
Winners, losers and margins
The immediate beneficiaries are importers who left positions unhedged. Tata Steel, which buys roughly 972 tonnes a quarter, said it had trimmed its landed cost by 15.4% since the start of the month and was deferring forward purchases in anticipation of further softness.

Equity markets have taken a constructive view of the sector. The E-Commerce index gained 18.9% 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.
| Contract | Level | 4-wk change | Volume change |
|---|---|---|---|
| Spot (domestic) | 84.5 | +13.2% | +8% |
| 1-month forward | 104.8 | +2.5% | +13.2% |
| 3-month forward | 111.2 | +17.4% | +14.1% |
| Index futures | 87.3 | +10.9% | +3.1% |
| Delivered premium | 86.3 | +18.6% | +10.5% |
Positioning and hedging
Global cues remain mixed. Demand data from Australia came in softer than expected, while restocking in France 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.
Timeline of key events

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

- Guidance trimmed
Two listed producers lower margin outlook in post-results calls.
- Hedging surge
Treasury desks extend hedge tenors as forward premiums ease.
- Range established
Prices consolidate; analysts debate the floor.
Physical premiums tell a similar story. Delivered premiums at Chennai compressed by about $411 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.
Expert commentary
“The disagreement among analysts is the most useful data point this quarter: it says positioning is no longer one-sided.”
“In my conversations with procurement heads, reliability is mentioned three times for every mention of price.”
“For E-Commerce, the margin of safety is in diversification: two markets, two gateways and two sources of finance.”
The range ahead
Derivatives data points to cautious positioning. Open interest in polished diamonds contracts rose 15.4% while implied volatility eased, a pattern desk traders read as hedgers adding protection rather than speculators adding risk. Options skew suggests more demand for downside protection than for upside.
What it means for you
Layer hedges at 40 to 60 percent of the next two quarters; defer discretionary forward buys while spreads remain tight.
Protect realisations with index-linked contracts; use input-cost relief to fund working-capital discipline rather than price cuts.
Favour names with order books beyond twelve months and low net debt; be cautious where valuations already price in earnings upgrades.
Extend hedge tenors while forward premiums are low and document the policy so decisions survive volatility.
