Sensex and Nifty Fall Analyzed

Key Points

• Investors cautious ahead of US Federal Reserve meeting and portfolio adjustments.
• Rupee depreciation due to high crude oil prices and FII outflows.
• Foreign Institutional Investors (FIIs) continue net selling.
• Rising crude oil prices fuel inflation concerns and market hesitancy.
• Increased volatility driven by mixed global economic signals.
• Technical indicators suggest potential profit-booking below 26,000.

Indian stock markets experienced a sharp decline on December 8, 2025, with the Sensex and Nifty50 indices falling significantly. This downturn was driven by a combination of factors, including anticipation of a US Federal Reserve meeting, the ongoing weakness of the Indian rupee, and continued selling pressure from foreign investors.

The primary catalyst for the decline was investor caution ahead of the US Federal Reserve’s two-day meeting, beginning December 9th. Investors are closely watching for potential interest rate adjustments and other economic signals from the Fed. Devarsh Vakil, Head of Prime Research at HDFC Securities, noted that “Investors positioned cautiously ahead of the upcoming FOMC meeting, additional inflation releases, and year-end portfolio adjustments.”

Another significant factor was the depreciation of the Indian rupee against the US dollar. Crude oil prices rose to two-week highs, adding to import bill pressures and raising inflation concerns. Jateen Trivedi, VP research analyst at LKP Securities, highlighted that “delays in the India-US trade deal and soaring bullion and metal prices continue to weigh on sentiment”.

Furthermore, Foreign Institutional Investors (FIIs) continued their net selling trend, withdrawing ₹438.90 crore in equity investments. This persistent selling pressure contributed to the market’s downward momentum. Rising crude oil prices added to the market’s vulnerability, prompting investors to adopt a defensive stance.

Adding to the overall volatility was the perspective of several market analysts. VK Vijayakumar, Chief Investment Strategist at Geojit Investments, emphasized the potential for ongoing instability, citing the rupee’s depreciation and the yen carry trade reversal. Ponmudi R, CEO at Enrich Money, pointed to the need for clearer signals to restore investor confidence.

Technical analysis suggested a potential for profit-booking if the index drops below 26,000, with option data confirming a consolidation bias.

Ultimately, market sentiment remains cautious as investors await clearer economic signals and policy decisions.
