Why India Still Resists Short Selling

In most mature financial markets, short sellers are an accepted part of the ecosystem, even if it is unpopular. They provide liquidity, improve price discovery and often expose corporate excesses. In India, however, short selling continues to evoke regulatory unease, whether in equities or bonds. The hesitation reflects a mix of historical memory, structural constraints, and regulatory caution. Yet this scepticism carries costs if India hopes to build deeper, more resilient capital markets.

Part of India’s suspicion toward short selling stems from its financial history.

The stock market scandals of the 1990s and early 2000s left a deep imprint on regulatory thinking. The 1992 securities scam associated with Harshad Mehta and the market manipulation episode linked to Ketan Parekh in 2001 prompted sweeping reforms aimed at curbing speculation and excessive leverage.

Although those episodes were not fundamentally driven by short selling, they reinforced a belief that aggressive trading strategies could destabilise markets. The regulatory instinct that followed prioritised stability over trading freedom. Short selling, often portrayed as betting against companies or markets, naturally fell under suspicion.

Over time, this caution became embedded in regulatory practice. The Securities and Exchange Board of India (SEBI) formally permits short selling in equities through the Securities Lending and Borrowing, or SLB, mechanism. In principle, therefore, the framework exists. In practice, however, participation in securities lending remains limited, making large-scale short selling cumbersome.

Beyond history, the structure of Indian financial markets also constrains the scope for short selling.

While the equity market has deepened considerably over the past two decades, the institutional architecture supporting securities lending remains relatively shallow. Without a large pool of lendable securities, establishing and covering short positions becomes difficult.

The challenge is even greater in the bond market.

India’s bond market, especially the corporate bond market, is dominated by banks, insurance companies, and pension funds that typically hold securities to maturity rather than actively trading them. Secondary market liquidity, therefore, remains thin.

Short selling requires the ability to borrow securities and sell them into the market. In an ecosystem where most bonds are locked in buy-and-hold portfolios, that flexibility is limited.

The RBI has also traditionally taken a cautious stance in the government securities market. Since government bonds underpin public borrowing and the transmission of monetary policy, policymakers tend to prefer a relatively stable yield environment.

An additional, often overlooked factor shaping this caution is the regulatory emphasis on benchmark government bonds.

In India, a small number of government securities, especially the most recent five- and ten-year “on-the-run” bonds, serve as benchmarks for the broader yield curve. Liquidity is deliberately concentrated in these securities through reopenings and market operations. The result is a peculiar market structure: a few bonds trade actively while many older securities remain largely dormant in institutional portfolios.

Despite its stated advantages, this structure has two consequences. First, borrowing securities outside the benchmark set becomes difficult, limiting the scope for short selling. Second, regulators become especially sensitive to volatility in benchmark yields because these yields serve as reference points for government borrowing and the broader interest-rate environment.

Yet this emphasis on benchmark stability may reflect a misconception. In deep bond markets elsewhere, short selling is not a threat to benchmark bonds; it is often the mechanism that keeps them liquid. Dealers routinely take short positions to provide two-way quotes, hedge portfolios and arbitrage movements along the yield curve. Without such mechanisms, markets often appear stable for long periods before adjusting abruptly.

Algorithmic Paradox
There is another paradox in India’s regulatory approach.

While regulators remain wary of aggressive short-selling strategies, they have simultaneously allowed, and in many ways encouraged, the rapid growth of algorithmic trading. A significant share of trading volumes on Indian exchanges is now generated by algorithmic strategies capable of executing thousands of orders within seconds.

The contrast is striking. Short selling influences market direction by allowing investors to profit when prices fall. Algorithmic trading influences market speed by accelerating order execution.

Regulators appear more comfortable with greater speed than with strategies that challenge market optimism. The result is a system in which trading velocities have increased dramatically, even as the strategic freedom to take contrarian positions remains constrained.

Limiting short selling carries broader consequences.

It weakens price discovery, since short sellers often help identify overvalued companies or questionable accounting practices. Restrictions also create one-sided markets. When investors can profit only from rising prices, speculative excess becomes more likely and corrections sharper.

The absence of active trading strategies, including short selling, also limits the development of India’s bond markets, where traders in advanced financial systems routinely take both long and short positions to manage interest-rate risk and arbitrage distortions.

Finally, shallow markets raise the cost of capital. When liquidity is weak and price discovery is incomplete, investors demand higher returns to compensate for uncertainty. Companies then rely more heavily on bank financing, reinforcing India’s bank-dominated financial system.

If India aims to build globally competitive capital markets, the focus should shift from restricting short selling to strengthening the infrastructure that supports it.

A deeper securities-lending framework would allow institutional investors to lend securities more actively. A more vibrant repo market would enable traders to borrow bonds for hedging and market-making. Encouraging professional market makers to take both long and short positions could improve liquidity across the yield curve.

Short sellers are rarely popular. Yet their role in financial markets is similar to that of critics in public life: uncomfortable but often necessary. If India’s ambition is to build deep and resilient capital markets, markets must allow both optimism and scepticism to operate.
