Sensex, Nifty Fall on Monthly Expiry Day as Crude Nears $115 and Fed Decision Looms

Indian stock markets opened lower on Tuesday, October 27, 2026, as monthly derivatives expiry, crude oil near $115 a barrel and caution ahead of the US Federal Reserve's policy decision combined to keep investors on the defensive.

The BSE Sensex, which closed at 73,606.75 on Monday, opened at 73,484.38 and was trading at 73,276.08 by 9.20 am, down 330.67 points or 0.45 per cent. The NSE Nifty 50, which ended Monday at 22,753.20, opened at 22,708.80 and slipped to 22,671.25, a fall of 81.95 points or 0.36 per cent in the same early window. Both benchmarks had rebounded about 0.7 per cent on Monday, ending a four-session losing streak, so Tuesday's gap-down partly gave back that recovery.

Why Tuesday is not an ordinary session

Tuesday is the monthly expiry day for all NSE derivatives contracts — Nifty, Bank Nifty, FinNifty, Nifty Midcap Select and Nifty Next 50, plus stock futures and options. Expiry days routinely bring sharper intraday swings as traders square off, roll over or settle positions, and market watchers had flagged exactly that risk before the open. One market commentator quoted in early coverage advised traders to avoid chasing the initial gap-down and to remain selective, warning that extreme volatility was expected through the session.

The BSE's monthly expiry follows on Thursday, October 29, so position adjustments will remain a theme for the rest of the week.

IT leads the fall; defence and FMCG hold up

Selling was concentrated in information technology and metals. Infosys was the early top loser, falling 2.51 per cent to Rs 1,136.70 from its previous close of Rs 1,166. JSW Steel declined 1.40 per cent to Rs 1,242.30, Asian Paints dropped 1.28 per cent to Rs 2,292.20, and TCS slipped 1.15 per cent to Rs 2,505.80. The Nifty IT index was down more than 1 per cent in early trade.

Not everything fell. Tata Consumer Products led the gainers, rising 3.04 per cent to Rs 965.00 from Rs 936.50 after an in-line September-quarter performance. Bharat Electronics (BEL) gained 1.35 per cent to Rs 367.90, Max Healthcare rose 1.25 per cent to Rs 845.40, and BSE Ltd and Shriram Finance also traded higher. Defence and fast-moving consumer goods counters were among the pockets of strength, while the broader market showed a mixed picture — midcap and smallcap indices traded in the green even as the benchmarks slipped.

Crude, yields and foreign selling: the three headwinds

Three macro factors explain the cautious mood. First, Brent crude was trading at around $115 a barrel in early trade, with reports putting it at $114.91, after holding above $114 through the session. Elevated oil prices matter directly for India, a large oil importer, because they feed into inflation expectations and the trade balance.

Second, the US 10-year bond yield was hovering around 4.97 per cent, keeping global borrowing costs high and making risk assets less attractive by comparison.

Third, foreign institutional investors (FIIs) sold equities worth Rs 1,462.49 crore on Monday, according to exchange data, extending a selling trend that has seen net foreign sales reach $4.75 billion in October alone. Domestic institutional investors, by contrast, bought Rs 2,609.57 crore net on Monday, extending their buying streak to a tenth consecutive session — a tug-of-war that has supported the market even as foreign money leaves.

Geojit's chief investment strategist was quoted in early coverage saying that Brent above $114 and the US 10-year yield near 4.97 per cent remain near-term headwinds, and that FIIs will stay in risk-off mode in this setting, even though improving second-quarter earnings and strong domestic fund inflows continue to support the market.

All eyes on Washington: the Fed meets October 27–28

The other big event this week is the US Federal Reserve's meeting on October 27–28, with its decision due on Wednesday, October 28. In a Reuters poll conducted October 16–20, 94 of 100 economists expected the Fed to hold its federal funds rate in the 3.75–4.00 per cent range at this meeting, after a 25-basis-point hike in September. All 100 respondents in the same poll expected a hike in December.

That combination — a widely expected pause now, a widely expected hike later — is why traders are cautious rather than panicked. A hold would confirm that policymakers want more time to judge the effect of September's tightening; any signal pointing firmly toward December, or beyond, could push bond yields and the dollar higher and weigh further on emerging-market flows, including into India.

What to watch for the rest of the day

Three things will decide whether Tuesday ends as a routine expiry-day dip or something worse. First, whether the Nifty holds above the 22,630 level flagged by analysts as critical support; holding it keeps a move back toward 23,000 alive, while a break below it could expose 22,250–22,000. Second, whether buying from lower levels in midcaps and smallcaps continues, which would suggest domestic buyers are still comfortable. Third, the corporate results calendar: 110 companies are due to report second-quarter results on Tuesday, including Tata Capital, United Breweries, Piramal Pharma, LT Foods and Radico Khaitan, and their numbers could move individual stocks even if the index stays soft.

The bottom line

Tuesday's fall is best read as expiry-day volatility layered on top of genuine macro pressure — expensive crude, high US yields and foreign selling — rather than a verdict on Indian companies themselves. With the Fed decision due on Wednesday and the BSE monthly expiry on Thursday, this week's direction is more likely to be decided in Washington and in the derivatives market than by any single earnings report.
