Indian benchmark equity indices opened sharply lower on May 12, with the Sensex and Nifty declining under the weight of surging crude oil prices and renewed geopolitical anxiety after President Donald Trump declared the US-Iran ceasefire was “on life support.”
At around 9:30 am, the Sensex was down 652.66 points or 0.86% at 75,362.62, while the broader Nifty50 declined 180.20 points or 0.76% to 23,635.65. The sell-off was broad-based, with risk-off sentiment extending across sectors as traders assessed the macro implications of a potentially prolonged Middle East conflict.
Three factors driving the market decline
Crude oil at $105: Brent crude rose to approximately $105 per barrel on May 12 — a level that is directly detrimental to India as the world’s third-largest oil importer. Elevated crude exacerbates domestic inflationary pressures, widens the current account deficit, weakens the rupee, and compresses corporate earnings across sectors from aviation and logistics to paints and chemicals. Oil marketing companies — already bleeding ₹30,000 crore per month in under-recoveries — face deepening financial strain with every dollar crude climbs above $100.
US-Iran ceasefire in doubt: Trump’s statement that the ceasefire was “on life support” after he dismissed Tehran’s response to a US peace proposal as “stupid” significantly darkened the geopolitical outlook. The ceasefire has been technically in place since April 8, but the breakdown in negotiations raises the prospect of a resumption of hostilities and a further tightening of shipping through the Strait of Hormuz. Markets that had partially priced in a resolution are now unwinding that optimism.
India VIX spikes to 18.56: The fear gauge — India’s volatility index — rose to 18.56, signalling a meaningful increase in market uncertainty and hedging activity. An elevated VIX typically coincides with accelerated selling as institutional investors increase put protection and reduce net long exposure. A VIX above 18 is historically associated with periods of sustained market stress rather than transient volatility, suggesting the current unease may persist beyond a single session.
Market context
The equity market decline on May 12 is part of a broader financial market deterioration playing out simultaneously across multiple asset classes in India. The rupee hit a fresh record low of 95.58 against the dollar in early trade. Indian 10-year bond yields rose 3 basis points to 7.06%. Global markets were also under pressure, with the KOSPI in Seoul falling 3% and European futures declining 1%.
US CPI inflation data — expected to come in at a hot 3.7% year-on-year — is due later in the day, and the print will be closely watched for signals on Federal Reserve policy. Any indication that rate cuts are off the table for 2026 would add another layer of pressure on Indian equities through the foreign portfolio investment channel.
