Analysts at Kotak Institutional Equities suggest that the Securities and Exchange Board of India's (SEBI) proposed measures to curb the rapid growth in the derivatives market could restrict accessibility for low-ticket retail investors, primarily those buying options.
Reports indicate that SEBI's expert committee on futures and options (F&O) has recommended several measures to control the growing volume in derivatives trading. These include:
- Increasing the minimum lot size of derivative contracts from Rs 5 lakh to Rs 20 lakh-Rs 30 lakh.
- Restricting weekly options to one expiry per stock exchange per week.
- Limiting the number of strike prices for options contracts.
Kotak Institutional Equities (KIE) highlights that options trading is highly concentrated, with 20 percent of retail option traders driving 90 percent of premiums. Increasing the lot size and reducing weekly expiries might be effective solutions, according to the brokerage.
KIE suggests that measures such as higher margins and position limit monitoring are likely aimed at curbing non-retail volumes. The effectiveness of these measures, combined with potential secondary effects, remains to be seen.
The brokerage points out that the real issue lies in the accessibility of options trading, which is complex but offers lower costs and higher leverage compared to other equity trading methods. This makes it potentially risky for investors.
Historical episodes in Korea and China illustrate the impact of regulatory interventions on trading volumes. In Korea, during 2010-11, a speculative bubble in options trading was deflated by increasing the minimum trading amount fivefold, leading to a significant drop in volumes. Similarly, China's futures trading market saw a sharp decline in volumes after 2015 when mandatory margin requirements were raised from 10 percent to 40 percent.
These cases demonstrate that regulatory changes in derivatives markets can have a significant and lasting impact on trading volumes. The Reserve Bank of India's recent interventions in the currency derivatives market also led to a major decline in volumes.
Despite concerns about the potential decline in volumes, some market veterans support SEBI's efforts to control heightened activity in the derivatives segment. Vijay Kedia, founder of Kedia Securities, described the current interest in the F&O segment as resembling a "stampede" rather than mere euphoria.
He emphasized the need for SEBI to intervene to prevent potentially unfavorable outcomes. Kedia's comments reflect a broader concern that the ongoing frenzy in the F&O market requires regulatory action to maintain stability and protect investors.
