Nifty and Sensex tumble as RBI rate hike and oil price surge pressure markets

The Nifty 50 slipped 0.76% to 22,424.70 while the BSE Sensex fell 0.63% to 72,187.97 on Thursday, October 8.

Market Move

The drop followed the Reserve Bank of India's decision to lift the policy repo rate by 25 basis points, bringing it to 5.5% – the first increase in almost four years aimed at curbing inflation amid robust growth. Higher borrowing costs sparked worries about tighter financial conditions, and a jump in crude oil prices added to inflation concerns.

Sector Highlights

Broad‑based selling saw most sector gauges turn negative, with fourteen out of the sixteen major sectors posting declines. Mid‑cap and small‑cap benchmarks each slipped about 0.8%. In contrast, the information‑technology segment rose 1.8%, driven by a 2.5% jump in Tata Consultancy Services shares as the company awaited its September‑quarter earnings later that day.

Context

Rate hikes often trigger short‑term market pullbacks because investors reassess profit margins and debt costs. Rising oil prices can further tighten consumer spending, reinforcing the downward pressure on equity indices.
