Indian shares tumble as oil tops $108 and US bond yields march toward five per cent

Indian shares suffered a sharp sell-off on Friday, 11 September, as soaring global crude oil prices and a relentless climb in US Treasury yields rattled investor confidence.

The Sensex crashed more than 740 points, or 1%, during intraday trading to hit a low of 74,160, while the Nifty 50 plunged around 250 points to 23,231. The sudden drop put the benchmark indices on track for their sixth consecutive week of losses, erasing the modest gains clawed back during a highly volatile trading session the previous day.

Geopolitics drive crude past $108

The primary trigger for the panic on Dalal Street is the escalating conflict in the Middle East. Brent crude surged past $108 a barrel after Yemen-based Houthi militants seized the Red Sea port city of Mocha and stepped up tanker attacks around the Strait of Hormuz.

For India, which relies on imports for more than 80% of its crude needs, expensive oil is a direct economic threat. Dr V K Vijayakumar, Chief Investment Strategist at Geojit Investments, warned that if oil prices sustain at these levels, the impact on India's GDP growth and corporate earnings "will not be insignificant."

Hareesh V, Geojit's Head of Commodity Research, added that crude remaining above $100 per barrel will widen India's current account deficit, fuel imported inflation, and put heavy pressure on the rupee.

US bond yields squeeze global liquidity

Compounding the oil shock is a quiet crisis in the US bond market. The yield on the 10-year US Treasury note touched 4.98% on Friday, creeping closer to the psychologically important 5% threshold.

As yields rise, global capital tends to flee riskier emerging markets in favour of safer US debt. Making matters tenser, federal funds futures are now pricing in a 70% probability of another US interest rate hike next week, signaling that central banks may keep monetary policy tighter for longer to combat stubborn inflation.

IPO boom drains local cash

There is also a domestic culprit behind the secondary market's struggles. India’s primary market is currently enjoying an unprecedented boom, with retail and institutional investors alike pouring massive sums of money into new public listings.

Dr Vijayakumar noted that high oversubscription rates and lucrative listing gains have sucked considerable liquidity out of the regular stock market. This diversion of funds is expected to continue ahead of the highly anticipated National Stock Exchange IPO, which opens for public subscription on 17 September.

Sectoral pain and investor advice

The selling on Friday was broad-based, hitting almost every sector. Real estate was the worst affected, with the Nifty Realty index plunging over 4%, followed by metals, which fell more than 2%. Heavyweight stocks like Bajaj Finance, Tata Steel, and Reliance Industries all posted sharp declines, though IT stocks like Tech Mahindra and HCLTech managed to buck the trend and post modest gains.

With volatility spikes evident—the India VIX volatility index rose nearly 4.5%—market analysts are advising retail investors to avoid rushing in to "buy the dip."

Santosh Meena, Head of Research at Swastika Investmart, recommended a strategy of selective caution. He advised investors to hold onto higher cash reserves and wait for clear signs of stabilisation—such as crude falling back below $100 and US yields peaking—before making any aggressive moves.
