Zerodha’s Nithin Kamath Explains How a ‘Boring’ SEBI Reform Quietly Boosted Retail Investor Wealth

Nothing 2025 08 13T084742.334

In the fast-paced and often headline-grabbing world of stock markets, it’s usually big IPOs, soaring stock prices, or market crashes that dominate the news cycle. Yet, according to Zerodha co-founder and CEO Nithin Kamath, one of the most impactful developments for retail investors in recent years came not from flashy announcements, but from a quiet regulatory tweak by the Securities and Exchange Board of India (SEBI).

Kamath recently shared how this “invisible” step by SEBI has generated massive windfall gains for ordinary investors without them even realising it. He emphasized that market reforms are often underestimated, but over time, they shape investor behaviour and build a more efficient, transparent, and profitable ecosystem for all participants.


The SEBI Step That Changed the Game

The reform in question revolves around upfront margin collection and pledge re-pledge mechanism for securities. Introduced gradually between 2020 and 2021, these rules aimed to:

  • Prevent misuse of client securities by brokers.
  • Ensure that investors maintain adequate margin before taking leveraged positions.
  • Increase transparency in collateral pledging.

Under the new system, investors who wish to trade in derivatives or take leveraged equity positions must pledge securities through a formal depository system instead of transferring shares to their broker. This seemingly small step removed a major loophole that had historically led to misuse and, in some cases, loss of investor capital.


Why Kamath Calls It a “Boring but Powerful” Move

To most traders, SEBI’s margin reforms sounded technical and inconvenient at first. It reduced the ability to trade on excessive leverage, required additional verification steps, and changed how brokers operated.

However, Kamath points out that these reforms:

  1. Protected Investors’ Holdings – Shares remained in the investor’s own demat account, reducing fraud risk.
  2. Prevented Overleveraging – Retail traders were less likely to blow up their accounts during volatile market swings.
  3. Boosted Confidence in the System – Transparency attracted more first-time investors.

The Result – A Surge in Retail Profits

While the reforms were intended for risk mitigation, they inadvertently led to higher profitability for retail traders. By curbing reckless leverage and overtrading, many small investors started holding positions longer, focusing on delivery-based investments, and benefiting from market rallies.

Kamath noted that Zerodha’s internal data showed an improvement in client performance post-reform. The reduced leverage forced disciplined trading, which over time improved win-loss ratios for many active traders.

How the Windfall Happened Without Retail Realising It

Retail investors didn’t necessarily see an immediate spike in profits after SEBI implemented the pledge-re-pledge system. Instead, the effect was gradual:

  • Lower leverage meant fewer forced liquidations during market volatility.
  • Investors stayed invested longer and captured larger trend moves.
  • Fraud prevention ensured their securities were never at risk from broker mismanagement.

When the markets rallied in 2023–2024, many retail investors unknowingly benefited from stronger portfolios built under the discipline of the new rules.


The Bigger Picture – Why Market Structure Matters

Kamath stressed that the Indian markets have gone through a silent revolution in the last decade. Reforms like:

  • T+1 settlement (faster money and share transfers)
  • Direct Mutual Fund plans (lower costs for investors)
  • Unified account opening via DigiLocker (streamlined onboarding)

…have combined to create a more trustworthy and efficient capital market, leading to record-breaking Demat account openings and retail participation in IPOs and equity markets.


Retail Investors – From Passive to Active Players

The pandemic period saw an explosion in new retail traders, many of whom started with speculative trading in options and penny stocks. However, SEBI’s reforms nudged them towards:

  • Equity delivery investments
  • Long-term mutual fund SIPs
  • Reduced reliance on margin trading

This shift, according to Kamath, is why Indian retail investors have enjoyed unprecedented portfolio growth in the past two years.

Kamath’s Advice for the Next Phase

Nithin Kamath believes retail investors should:

  1. Embrace Discipline – Treat capital preservation as important as profit-making.
  2. Diversify Beyond Stocks – Use bonds, index funds, and ETFs for stability.
  3. Avoid Overtrading – Focus on fewer, high-quality trades or investments.
  4. Stay Educated – Regulatory changes may look “boring” but can have huge financial impacts.

Conclusion – Silent Reforms, Loud Results

What appeared to be a technical compliance measure from SEBI has proven to be one of the most beneficial reforms for retail investors in recent years. By reducing leverage, improving transparency, and ensuring investor assets remain safe, SEBI’s pledge-re-pledge mechanism has helped thousands of investors make better, more profitable decisions without realising it.

Kamath’s takeaway is clear: in stock markets, boring is often brilliant. The best results sometimes come not from risky bets, but from structural improvements that quietly work in the background, ensuring fairness and safety for everyone.
