Sensex, Nifty slip as 0.8% rally fades on RBI fears

What happened in Thursday’s session

Indian equities ended lower on Thursday after giving up strong early gains, as traders weighed concerns over possible Reserve Bank of India (RBI) rate hikes, inflation risks and global uncertainty. The BSE Sensex closed 135.03 points lower at 75,183.36, while the NSE Nifty 50 slipped 4.30 points to end at 23,654.70. The day’s price action underlined a familiar pattern in recent sessions, where upbeat global cues helped markets open firm but domestic macro worries capped risk-taking.

Despite supportive factors such as softer crude oil prices and a stronger rupee, investors remained cautious. The session also coincided with the weekly derivatives expiry for the Sensex, a routine event that typically adds volatility as positions are rolled over or closed.

Early rally driven by crude drop and US-Iran headlines

Markets started the day on a strong note, with the Sensex rising more than 500 points in early trade. The initial upmove followed a sharp overnight fall in crude oil prices after US President Donald Trump said negotiations with Iran were in their “final stages”. Lower crude prices generally support India’s macros by easing imported inflation pressures and improving the trade balance, which can help sentiment in equities.

But the early optimism did not hold. As the session progressed, the focus shifted from the near-term benefit of softer crude to broader macro risks, including the possibility of tighter domestic monetary policy if inflation remains sticky.

Why gains faded: RBI tightening and inflation concerns

The rally lost momentum as investors turned cautious over the possibility of interest rate hikes by the RBI amid persistent inflation concerns linked to high crude oil prices. While crude softened during the session, the market narrative reflected uncertainty around energy prices and their potential to re-ignite inflation.

Vinod Nair, Head of Research at Geojit Investments Limited, said domestic equities erased early gains as concerns over possible RBI tightening and weak manufacturing data overshadowed optimism from falling crude. “Domestic equities erased early gains as concerns over potential RBI rate hikes and weak manufacturing PMI data outweighed optimism from softer crude prices,” Nair said. He also pointed to “uncertainty around US-Iran negotiations” and “a weaker growth outlook” as factors keeping macro concerns elevated.

Weekly derivatives expiry added to volatility

Thursday’s session coincided with the weekly derivatives expiry for the Sensex. Expiry sessions can amplify intraday swings as traders adjust positions, close contracts, and roll exposure to the next series. In this context, even a modest shift in sentiment can lead to sharp reversals from early highs.

Both benchmark indices climbed nearly 0.8% during intraday trade before paring gains. The fade from intraday strength to a weaker close reflected cautious positioning rather than a single sector-specific trigger.

Where the indices closed

The benchmarks finished close to flat but in negative territory, underscoring how the market struggled to sustain the early risk-on move.

Stock-specific moves mentioned

Select stocks saw sharper moves than the benchmark even as the headline indices ended with small declines. Bajaj Finance was cited as falling 2%, while IndiGo was noted as rising 3%. The broader tape, however, was driven by macro cues and derivatives-related positioning rather than a uniform sector trend.

Global uncertainty stayed in focus

Even with the crude-led tailwind early in the session, uncertainty around US-Iran negotiations remained a live risk factor for global markets. Comments suggesting progress can push oil down, but any shift in tone can quickly reverse expectations. For Indian equities, this matters because energy prices can influence inflation expectations, the rupee, and the policy outlook.

Investors also weighed global uncertainty more generally. In such conditions, markets often demand clearer evidence on inflation and growth trends before extending rallies.

Market impact: what the day’s move signals

The day’s close signalled that the market is still sensitive to the RBI policy narrative. Rate-hike fears typically weigh on valuations because higher rates can raise borrowing costs for companies and reduce the present value of future earnings. Inflation-linked concerns also influence sector leadership, with investors often preferring defensives or exporters when domestic rates look set to tighten.

At the same time, the relatively small decline on the Nifty suggested that risk appetite was not fully off. Softer crude and a stronger rupee provided support, but not enough to override the macro caution highlighted by weak manufacturing PMI data and the possibility of domestic monetary policy tightening.

Why this session matters for investors

Thursday’s trade showed how quickly global tailwinds can be neutralised by domestic macro concerns. Even when crude drops and the rupee strengthens, markets can struggle if investors believe inflation risks could lead to tighter RBI policy. The intraday reversal after a near 0.8% rise also underlined the importance of watching positioning around derivatives expiry.

Conclusion

Indian benchmarks ended marginally lower after strong early gains faded, with rate-hike concerns, inflation risks, weak manufacturing data and expiry-day volatility dominating the close. The next set of market cues will likely continue to revolve around crude trends, global geopolitical developments and signals on domestic monetary policy expectations.
