NEPSE Circuit Breaker Reform Proposed by SEBON Directive
11th March 2026, Kathmandu
The Securities Board of Nepal (SEBON) has formally directed the Nepal Stock Exchange (NEPSE) to undertake a comprehensive review of the existing circuit breaker mechanism. This regulatory move follows intense investor frustration and widespread market debate sparked by recent trading sessions where the index hit the 6 percent upper threshold in a matter of seconds.
NEPSE Circuit Breaker Reform
As Nepal’s capital market matures, the consensus among regulators, brokerage firms, and retail investors is that the current three-stage halt system may no longer be equipped to manage the velocity of modern, sentiment-driven trading.
The Limitations of the Current Structure
The existing circuit breaker framework, which mandates halts at 4 percent (20 minutes), 5 percent (40 minutes), and 6 percent (full-day suspension) changes, was designed during a different era of Nepali finance. While these thresholds provide a necessary cooling-off period during periods of extreme fear or euphoria, recent data highlights a significant challenge: market efficiency. When a 6 percent swing occurs within less than two minutes of total trading time, the circuit breaker effectively acts as a kill-switch rather than a mechanism for stabilization.
The recent election-driven rally saw the NEPSE index climb 162.93 points to close at 2,875.43, with a total turnover of NPR 555.9 million generated in less than two minutes of operation. While this indicates robust investor confidence following political shifts, the rapid suspension of trading prevents the market from reaching a true price equilibrium. This “locking” of the market can lead to liquidity crunches and frustration for institutional players who need to execute larger orders.
Potential Avenues for Reform
SEBON’s directive to NEPSE emphasizes the need for a more “scientific” approach. Potential reforms currently being discussed by financial analysts and regulatory committees include:
Dynamic Threshold Adjustments: Implementing a system where circuit breaker percentages are reviewed annually based on historical volatility and market capitalization growth.

Intraday Limit Flexibility: Exploring whether the 4 percent, 5 percent, and 6 percent levels should be applied to individual stocks differently than to the broad market index.
Adjusted Halt Intervals: Shortening the duration of trading halts while maintaining the circuit breakers, or allowing for a “call auction” phase during the halt to help build a more accurate opening price upon resumption.
International Benchmarking: Adopting models similar to the New York Stock Exchange or the Bombay Stock Exchange, where circuit breakers are triggered by broader index levels and are supported by advanced volatility-management algorithms.
Balancing Stability and Liquidity
The core challenge for NEPSE is to design a system that protects retail investors from catastrophic panic-selling without impeding the market’s ability to price assets efficiently. Market experts argue that a system that triggers a full-day halt after a 6 percent movement may be overly restrictive in a high-growth environment where sudden positive catalysts—such as major political or economic reforms—are expected.
Looking Ahead
The proposal, which NEPSE is currently tasked with drafting, is expected to be a critical document for the future of Nepal’s financial infrastructure. By aligning NEPSE rules with modern international practices, the regulator hopes to create a more resilient trading environment. As the committee reviews the data from the most recent circuit-hit sessions, the focus remains on ensuring that investors have the time to make rational decisions without sacrificing the fluidity of the market.
For the individual investor, these potential changes are vital to watch. A more flexible and responsive circuit breaker system could reduce the “all or nothing” nature of high-volatility days, potentially leading to more consistent trading sessions. Regulatory updates will be released as the proposal progresses through the SEBON review process, and all stakeholders are encouraged to monitor official NEPSE disclosures regarding these upcoming structural adjustments.
