Nifty Metal Tumbles as $6B+ Index Rebalancing Triggers Broad Commodity Sell-off
The Nifty Metal index is under pressure as annual commodity index rebalancing drives large-scale selling across metals. Precious metals face 12% correction with $6B+ outflows expected, while industrial metals show mixed outlook with copper cooling despite structural deficits and aluminium positioned for potential deficit in 2026.

The Nifty Metal index is experiencing significant pressure as global commodity markets witness sharp volatility driven by the annual rebalancing of major commodity indices. This technical adjustment is triggering large-scale fund reallocations across precious metals, energy, and industrial metals, creating widespread selling pressure across the metals sector.
Index Rebalancing Drives Precious Metals Correction
According to Mohammed Imran, Commodity Analyst at Mirae Asset Sharekhan, precious metals have entered a corrective phase with further downside expected due to mean reversion in index weightages. The Bloomberg Commodity Index rebalancing reveals the scale of adjustment needed:
| Metal | Start 2025 Weight | End 2025 Weight | Adjustment Required |
|---|---|---|---|
| Gold & Silver Combined | 18.80% | 30.00% | Significant reduction needed |
| Expected Sell-off | 12.00% | ||
| Global Futures Outflows | $6.00+ billion |
"Silver could see sharper pressure compared to gold," Imran noted, projecting that Comex silver may test support levels near $70.00. The rebalancing exercise is expected to continue pressuring precious metals as passive tracking funds adjust their allocations.
Energy Sector Shows Mixed Outlook
While precious metals face headwinds, the energy basket presents a more nuanced picture. The index rebalancing has reduced exposure to US benchmarks like WTI crude and natural gas, but increased Brent crude's weightage:
| Energy Commodity | Previous Weight | New Weight | Outlook |
|---|---|---|---|
| Brent Crude | 8.03% | 8.36% | Potential move to $62/barrel |
| WTI Crude | Reduced exposure | Lower weight | Negative impact |
| Natural Gas | Reduced exposure | Lower weight | Negative impact |
This shift could provide selective support to Brent prices in the near term, according to Imran's analysis.
Industrial Metals Face Mixed Pressures
Copper, despite rallying more than 40.00% since early 2025, may see near-term correction due to index adjustments, even as its weightage rises to 6.36% in 2026. Imran expects prices to cool towards the 13,000 level in coming weeks.
However, structural factors remain supportive for copper:
| Supply Factor | Impact | Timeline |
|---|---|---|
| Global Refined Deficit | 500,000-600,000 tonnes | Revised higher |
| Grasberg Mine Disruption | 3.00% of global production | Full capacity unlikely before end-2027 |
| Previous Deficit Estimate | 200,000-300,000 tonnes | Significantly underestimated |
Aluminium and Zinc Diverge
Among other industrial metals, aluminium appears better positioned for 2026. Despite China capping production at around 45.00 million tonnes, new Indonesian capacity could add 500,000-600,000 tonnes this year. Substitution demand from expensive copper and steady global consumption could push aluminium into a deficit of 200,000-300,000 tonnes.
Zinc faces a different trajectory. After recent European tightness pushed prices into backwardation, rising Chinese exports have eased supply concerns. With the market now in contango, Imran expects zinc prices to drift lower towards 2,900 in coming months.
Market Outlook and Investment Implications
Analysts caution that near-term volatility driven by technical rebalancing may continue affecting the Nifty Metal index and broader commodity markets. However, underlying demand-supply dynamics will remain the key driver for commodity prices in 2026. The current correction, while significant, appears largely technical in nature rather than reflecting fundamental deterioration in metals demand.
