Indices fall as elevated crude prices, rising global bond yields weigh

Summary

Indian equity benchmarks ended lower on Tuesday, and the Nifty posted its longest losing streak since September 2025 as fading hopes of an end to the war in Iran kept crude oil prices elevated and pushed global bond yields higher, weighing on investor appetite for riskier assets. The benchmark Nifty on Tuesday posted its sixth consecutive losing session and ended the session at 24,155, a decline of 133 points, or 0.6 per cent. The Sensex posted its third consecutive session of losses and ended the session at 77,236, a decline of 493 points, or 0.6 per cent. The total market capitalisation of BSE-listed firms ended the session at Rs 490.8 trillion, down Rs 1.7 trillion. Investor sentiment deteriorated after prospects for a peace agreement between the US and Iran weakened further. Iran threatened to shift to a “fully offensive” military posture after efforts to negotiate a permanent end to the conflict stalled, while US President Donald Trump ruled out extending a temporary ceasefire arrangement. The setback also dimmed hopes of a swift resumption of tanker traffic through the Strait of Hormuz, a key route for global energy supplies. Brent crude was trading at $89.80; in the last seven sessions, Brent crude prices had risen by 10 per cent. Higher oil prices are bad for India, a heavy net importer. Adding to the pressure, long-dated bond yields climbed to multi-decade highs. The 30-year US bond yield stood at 5.32 per cent, the highest level since June 12, 2007. “Crude oil remained the primary drag on market sentiment, while rising US bond yields and weak global cues prolonged the risk-off trend in Indian equities. Investor anxiety increased as hopes for a Middle East resolution faded after the temporary US-Iran ceasefire expired, heightening concerns about renewed inflation. Elevated US yields further reduced the attractiveness of emerging markets, and IT stocks led losses amid fears that persistently high interest rates could dampen global technology spending. Although domestic fundamentals continue to be supportive, sustained high crude prices and rising input costs could pressure recent earnings upgrades, prompting investors to remain cautious in the near term,” said Vinod Nair, head of research at Geojit Investments. Going forward, investors will be tracking geopolitical developments to gauge the market trajectory. The market breadth was weak, with 2,426 stocks declining and 1,890 advancing. Foreign portfolio investors (FPIs) were net buyers of Indian equities worth Rs 1,651 crore, and domestic institutions were net buyers worth Rs 2,579 crore. “Going forward, the 24,030–24,000 zone is expected to act as a key support area for the Nifty. A decisive breakdown below the 24,000 mark could accelerate selling pressure and trigger a deeper correction towards the 23,850 level,” said Sudeep Shah, head — technical and derivatives research at SBI Securities.

Kpler data indicates that transits through the Strait of Hormuz decreased to six vessels on Tuesday, well below the recent daily average, amid conflicting official statements regarding the waterway's status; U.S. President Donald Trump asserted the strait is open and no negotiations with Iran are ongoing, while Iranian authorities have claimed it remains shut.

Consequently, major Chinese shipping firms report keeping tankers out of the region since late July, raising concerns about disruptions to global oil and LNG supplies, though the full extent of these logistical impacts remains under assessment.

Bitcoin prices rose in contrast to U.S. stock indices, with the S&P 500 rebounding from its lowest level since August 4. This divergence followed President Trump’s social media assertions that the Strait of Hormuz is fully operational and free of mines, which contradicted earlier reports of a naval blockade and territorial disputes with Iran.

Market data showed WTI crude oil remaining relatively stable, while 30-year U.S. Treasury yields reached 5.34%, a level not seen since January 2007.
