The Cost of Policy Uncertainty

Governments often assume that confidence follows growth. In reality, growth follows confidence. Investors can adapt to higher taxes, tighter regulations and even periods of market volatility. What they struggle to absorb is uncertainty. It is this uncertainty that Budget 2026 has injected into India's capital markets through a sharp increase in the Securities Transaction Tax (STT) on futures and options and changes in the taxation of share buybacks. While the government's objective of raising revenue and curbing speculative excess is legitimate, repeatedly rewriting the tax rules of the market risks undermining one of India's greatest economic assets: policy credibility.

The government's rationale is not without merit. Retail participation in the futures and options (F&O) segment has surged, with SEBI repeatedly warning that the overwhelming majority of individual traders lose money. Raising STT, with futures increasing from 0.02% to 0.05% and options to 0.15%, seeks to discourage excessive speculation while generating additional revenue. Likewise, taxing share buybacks as capital gains aims to eliminate tax arbitrage and improve fairness. These measures align with the broader goals of fiscal consolidation and raising India's tax-to-GDP ratio.

Yet, good intentions alone do not make good policy. Financial markets judge governments not merely by the taxes they levy but by the consistency with which they frame them. Markets can price higher taxes; they cannot easily price policy uncertainty. Every abrupt revision raises a larger question: if securities taxation can change sharply today, what prevents similar surprises tomorrow? The cumulative effect is not merely higher transaction costs but a gradual erosion of investor trust.

The immediate consequences are evident. Higher transaction costs reduce the attractiveness of high-frequency and short-term trading, potentially lowering liquidity in derivatives markets. But derivatives are not merely speculative instruments; they are essential for price discovery and risk management. Lower liquidity eventually raises costs for genuine investors and businesses that rely on these markets to hedge risks. Brokerages, exchanges and smaller market participants are also likely to feel the impact through declining trading volumes.

More fundamentally, these measures expose a contradiction in India's economic strategy. The government encourages households to move savings from gold and real estate into financial assets, promotes ease of doing business, and seeks to transform GIFT City into an international financial hub. Yet it simultaneously raises the cost of participating in capital markets through frequent tax revisions. A nation aspiring to attract global capital cannot afford policy signals that appear inconsistent with its own investment narrative.

This concern extends beyond domestic investors. Global capital is highly mobile. Investors compare not only tax rates but also the predictability of regulatory and fiscal regimes across competing financial centres such as Singapore, Dubai, London and New York. Taxes alone rarely drive investors away. Uncertainty often does. Frequent and poorly signalled changes increase what economists call the "uncertainty premium", prompting investors to demand higher returns or shift capital to more predictable jurisdictions.

The larger issue is institutional rather than fiscal. India lacks a coherent medium-term framework for securities taxation. Mature financial markets typically introduce significant tax reforms after extensive consultation, transparent impact assessments and phased implementation. Such practices strengthen confidence even when taxes increase. By contrast, recurring and abrupt revisions create the impression that capital markets are viewed primarily as convenient sources of revenue rather than as strategic institutions that mobilise savings, allocate capital and finance economic growth.

Fiscal policy must therefore resist the temptation of treating buoyant financial markets as easy revenue targets. Higher STT may boost collections in the short run, but reduced trading volumes and weaker participation could eventually shrink the tax base itself. More importantly, if capital markets become less efficient or attractive, the broader economy bears the cost through slower capital formation, weaker entrepreneurship and reduced investment. India's challenge is not merely extracting more tax from existing activity but expanding the scale of productive investment.

There are better alternatives. Investor protection should continue through SEBI's regulatory reforms, stronger financial literacy and better risk disclosures rather than relying predominantly on higher transaction costs. Future changes to securities taxation should be gradual, well-signalled and preceded by meaningful consultation with market participants. A published medium-term roadmap would reduce uncertainty and reinforce India's credibility as an investment destination while distinguishing speculative excess from genuine hedging.

Every Budget demands difficult trade-offs, and mobilising resources for development is both necessary and legitimate. But confidence is not an inexhaustible fiscal resource. Markets forgive volatility; they rarely forgive unpredictability. If India genuinely seeks to become a developed economy by 2047 and a global financial hub, its capital markets must be governed not by fiscal expediency but by policy stability. A predictable tax regime is not a concession to investors. It is an investment in India's own economic future.
