Silver ETF investors faced unexpected volatility as NSE revised its circuit calculation method from T-2 to T-1, ensuring more accurate price limits and smoother trading.
Silver ETF Circuit Calculation Issue Explained
Silver exchange-traded funds recently witnessed unusual confusion on the National Stock Exchange, and naturally, many investors wondered what went wrong. Although circuit limits usually protect traders from extreme volatility, this time the calculation itself created the problem. Therefore, NSE stepped in quickly and changed the method to avoid further disruption.
Typically, the exchange calculates upper and lower circuits using the T-2 method, which means prices from two trading days earlier. However, silver prices moved sharply overnight on the commodity market, and consequently, the old formula failed to reflect real-time risk. As a result, the circuit limits appeared unrealistic and disconnected from actual ETF prices.
Why T-2 Calculation Created Confusion
Under the earlier system, NSE calculated the lower circuit for Kotak Silver ETF at ₹291.65. However, the ETF had already closed lower at ₹286.93 on Friday. Therefore, the lower circuit ended up higher than the closing price, which logically made no sense. Because of this mismatch, traders struggled to understand where the stock could actually trade.
Meanwhile, silver prices on MCX plunged nearly 27% late Friday night. Consequently, investors expected heavy selling pressure when markets reopened. However, since the circuit did not match market reality, panic and uncertainty increased even before trading started.
NSE Switches to T-1 Method for Better Accuracy
To fix the issue quickly, NSE changed the computation base from T-2 to T-1. In simple terms, the exchange started using the previous day’s net asset value (NAV) instead of older data. As a result, the circuit limits became more aligned with current market conditions.
Moreover, this step improved price discovery and reduced the risk of technical blocks during trading. Therefore, investors could trade with greater clarity and confidence rather than guessing the real support levels.
Impact on Kotak Silver ETF and SilverBees
After the revision, Kotak Silver ETF’s lower circuit was recalculated at ₹256.11 based on a NAV of ₹320.15. Consequently, the ETF dropped sharply and hit its lower circuit, falling around 10.74%. Similarly, SilverBees also touched its lower circuit at ₹252.5, confirming strong selling pressure across the segment.
Additionally, fund managers explained that the new system better reflects commodity-linked movements. Since silver ETFs closely track physical silver prices, sudden MCX crashes can immediately impact ETF valuations. Therefore, faster and more recent calculations help maintain fair trading.
Expert View on the New System
Satish Dondapati, Fund Manager at Kotak Mahindra, stated that the T-1 methodology offers more practical and realistic results. Moreover, he indicated that this approach might continue temporarily, especially if ETFs keep hitting lower circuits. Consequently, exchanges can prevent further mismatches during volatile sessions.
From an investor’s perspective, this move strengthens trust in the exchange’s risk management system. In addition, it demonstrates that regulators actively monitor unusual situations and respond quickly when needed.
Old vs New Circuit Calculation Comparison
| Factor | T-2 Method (Old) | T-1 Method (New) |
|---|---|---|
| Base Price | Two days old data | Previous day NAV |
| Accuracy | Lower | Higher |
| Market Relevance | Often outdated | Real-time aligned |
| Trader Confidence | Moderate | Stronger |
What Silver ETF Investors Should Do Now
First, investors should closely track MCX silver prices because ETFs directly follow commodity movements. Moreover, they must compare ETF price with NAV before placing trades. Additionally, they should avoid panic selling during circuit hits and instead evaluate long-term fundamentals.
On the other hand, short-term traders must stay alert because commodity-based ETFs often show sharp volatility. Therefore, using stop-loss strategies and disciplined entries becomes essential. Consequently, better planning can reduce losses during sudden price swings.
Final Takeaway for Traders
Overall, NSE’s quick decision helped stabilize trading and prevented further confusion. Although the T-2 system works in normal markets, it struggled during extreme price crashes. Therefore, switching to T-1 ensured better price alignment. Moreover, the change restored investor confidence and improved transparency. Consequently, silver ETF trading should now remain smoother and more predictable. In addition, informed investors can use these updates to make smarter decisions.
