- Silver’s 9% MCX slide and higher margins are reshaping short‑term volatility.
- Hindustan Zinc’s EBITDA is 40‑45% tied to silver, amplifying upside when prices rebound.

You missed the warning sign in Hindustan Zinc’s plunge, and it could cost you dearly.
On Thursday the stock sank to a intraday low of Rs 594 after the MCX silver contract tumbled 9% in the first trading hour. The drop was not an isolated commodity glitch; it was the catalyst that exposed the thin line Hindustan Zinc walks between base‑metal stability and precious‑metal volatility. For investors, the episode offers a rare window to assess whether the current pain is a temporary dip or the opening act of a larger silver‑driven rally.
Why Hindustan Zinc’s Silver Sensitivity Is a Double‑Edged Sword
Hindustan Zinc (HZL) is the world’s fourth‑largest silver producer, delivering roughly 22.5 million ounces annually. That places it ahead of Grupo Mexico and only behind giants like Fresnillo and Newmont. However, unlike pure zinc miners, roughly 40‑45% of HZL’s EBITDA is linked to silver realizations when prices are healthy. The company’s cost curve for zinc sits in the lowest quartile globally, and its mine life stretches about 25 years, giving it a sturdy operating foundation.
When silver prices surge, the revenue uplift is almost immediate because mining costs remain relatively flat. The opposite is true when silver falters – the fixed cost base erodes margins quickly, pulling earnings down faster than a comparable zinc‑only peer would experience. This hybrid exposure means the stock behaves like a precious‑metal proxy on the upside and a base‑metal play on the downside.
How MCX Margin Changes Amplify Short‑Term Volatility
The MCX exchange imposed higher maintenance margins on both gold and silver futures after a routine risk review. Higher margins increase the capital required to hold leveraged positions, prompting many traders to unwind or scale back exposure. The immediate effect is a spike in price volatility, as seen by the 9% plunge in silver futures for March 2026.
For HZL investors, the key takeaway is that margin tightening can accelerate price swings without a fundamental shift in supply‑demand dynamics. In practice, this means you may see sharper intraday moves, but the underlying fundamentals – mine life, cost structure, and global silver demand – remain unchanged. Understanding the margin effect helps separate noise from signal.
Sector‑Wide Ripple: Zinc and Precious Metals Outlook
Globally, zinc demand is being buoyed by infrastructure spending and green‑energy projects, while silver enjoys a dual role as an industrial catalyst and a safe‑haven asset. The convergence of these trends creates a favorable backdrop for HZL’s diversified exposure.
Peers such as Tata Steel’s zinc segment and Adani Power’s renewable‑energy‑linked copper holdings are experiencing their own commodity‑driven cycles. However, they lack the silver upside that can act as a price‑floor during zinc downturns. Consequently, HZL’s valuation multiples (EV/EBITDA) have a broader range (5‑11×) compared to pure zinc peers, which often trade tighter due to less earnings volatility.
Historical Silver Slumps: Lessons for Today’s Investor
During the 2013‑14 silver correction, several mixed‑metal miners saw their shares dip 12‑15% before rebounding as the metal recovered in 2015‑16. Those that maintained disciplined cost controls and continued capex investment outperformed peers that cut back on growth spending.
HZL’s current cost of production sits at $940 per tonne – the lowest in five years and 5% better QoQ. History suggests that firms with a low‑cost base can weather temporary price shocks and emerge stronger when the market reverses. This pattern reinforces the argument for a medium‑term bullish stance if you can tolerate short‑term turbulence.
Technical Metrics: EV/EBITDA, Cost‑per‑Tonne Explained
EV/EBITDA (Enterprise Value to Earnings Before Interest, Taxes, Depreciation, and Amortization) gauges how the market values a company’s operating earnings relative to its total capital structure. HSBC’s upgrade to 11× FY27E EV/EBITDA signals confidence that earnings will rise faster than the market currently anticipates.
Cost‑per‑Tonne is a direct measure of the cash required to produce a tonne of metal. HZL’s $940/tonne benchmark is competitive, especially when the global zinc cost curve is trending upward due to rising energy prices. A lower cost base translates into higher margin resilience when commodity prices dip.
Investor Playbook: Bull vs. Bear Cases
Bull Case
- Silver rebounds above Rs 2,70,000 per kg, lifting EBITDA by 15‑20%.
- HSBC’s 11× EV/EBITDA valuation aligns with a 12‑month earnings upside target of Rs 800‑850.
- Capex rollout of $700 million in FY26 drives incremental production without eroding cash flow.
- Cost‑per‑tonne remains below $960, protecting margins against zinc price volatility.
Bear Case
- Silver stays depressed below Rs 2,30,000 per kg for two consecutive quarters.
- Higher MCX margins force a prolonged sell‑off in futures, extending price pressure.
- Unexpected grade variability raises production costs above $1,000 per tonne.
- Capex overruns strain free cash flow, prompting dividend cuts.
Positioning your portfolio now hinges on your view of silver’s trajectory and HZL’s ability to maintain its low‑cost advantage. If you believe the metal’s industrial demand will outpace short‑term price pain, the stock offers a compelling upside potential at current levels. Conversely, if you anticipate a prolonged silver slump, a cautious stance or hedged exposure may be prudent.
