The Indian equity benchmarks remained locked in a relentless bear grip on Tuesday, September 29, 2026, heading toward the worst September derivatives expiry cycle in a quarter-century. Despite intermittent bottom-fishing attempts at lower price bands, the benchmark Nifty 50 has surrendered approximately 6.7% of its value over the month. This steep drawdown eclipses the previous downturns of 6.5% witnessed in September 2020 and 6% in September 2018, marking the single sharpest September contraction on Dalal Street since the historic 16% collapse during the 2001 global market meltdown. A toxic convergence of global headwinds and domestic liquidity shifts has systematically choked off relief rallies across frontline indices.

Triple Macro Shocks: Crude Tops $105, Bond Yields Hit Multi-Decade Peaks, and the Rupee Sinks to ₹96

At the center of this prolonged market correction is an escalating energy crisis and spiking sovereign debt costs worldwide. Brent crude has surged above the $105-per-barrel threshold, logging an 11% leap over the past six months and a massive 77% rally over the past year, primarily fueled by unresolved West Asian geopolitical friction and stalled talks between Washington and Tehran. Simultaneously, US fixed-income markets have sent shockwaves across global risk assets, with the US 10-year Treasury yield hitting 20-year highs and the 30-year yield breaching 25-year peaks. Compounding the pain for Indian corporate margins, the Indian rupee has plunged to record lows around ₹96 against the US dollar—falling 1% in September alone and depreciating nearly 7% across 2026—severely amplifying imported inflation risks alongside elevated crude invoices.

The FII Exodus, Liquidity-Draining Mega IPOs, and Impending Central Bank Rate Hikes

The market's structural liquidity has faced a dual squeeze from foreign capital flight and unprecedented primary market paper supply. Foreign Institutional Investors (FIIs) have aggressively pulled out approximately ₹2.50 lakh crore ($26 billion) from Indian cash markets in 2026, recording net outflows in six of the past nine months, with the aggressive selling resuming forcefully this September after a brief summer reprieve. Adding to the cash drain, the domestic primary market has absorbed nearly ₹1.13 lakh crore across 100 mainboard IPOs alongside ₹88,150 crore in large block deals this year, exhausting secondary market trading depth. Topping off investor anxiety are imminent monetary policy tightening expectations, with money markets pricing in two additional interest rate hikes by the US Federal Reserve this year and widespread projections of an impending repo rate hike by the Reserve Bank of India (RBI) in its upcoming October policy review.
