Indian stock markets extended their losing streak to six sessions on Tuesday, August 18, 2026. The Sensex closed down by 492.70 points at 77,235.46, while the Nifty fell 132.75 points to 24,154.90, pressured by rising global crude oil prices and geopolitical tensions.
Indian stock markets ended the trading session in the red on August 18, 2026, as both key indices recorded significant losses. The BSE Sensex fell by 492.70 points to close at 77,235.46. Similarly, the Nifty 50 dropped by 132.75 points, ending the day at 24,154.90. This decline marks the sixth consecutive day that the Nifty index has finished lower, highlighting a period of sustained selling pressure in the market.
The downturn is largely linked to concerns over global stability. Brent crude oil prices have climbed above $90 per barrel, driven by ongoing geopolitical tensions in the Middle East. For the Indian economy, rising oil prices are a concern because the country imports a large portion of its energy needs. When global oil costs go up, it can increase inflation and put pressure on company profit margins, making investors more cautious about holding stocks.
The selling pressure was widespread across several major sectors. Companies in the IT, realty, FMCG, metals, and financial services industries saw notable declines as investors reduced their exposure to these segments. Despite the broad downward trend, there was some resilience in other parts of the market. Sectors such as auto, pharmaceuticals, healthcare, and oil and gas managed to buck the trend and recorded gains during the session.
The market direction in the coming days will likely depend on how crude oil prices and geopolitical situations evolve. Investors will also be tracking the activity of foreign institutional investors, as sustained selling from this group can impact market liquidity. Additionally, any new data regarding domestic macroeconomic health and corporate earnings will be relevant for assessing the impact of these global factors on Indian businesses.
