The Indian stock markets, comprising the Bombay Stock Exchange (BSE) and the National Stock Exchange (NSE), are slated to hold full trading sessions on Sunday, February 1, 2026. This exceptional decision is to facilitate an immediate market response to the Union Budget 2026-27, which Finance Minister Nirmala Sitharaman will present on that day. The Budget presentation is scheduled for 11 am, marking a rare event as it is the first time since 2000 that India's annual financial statement will be delivered on a Sunday. Both the BSE and NSE have issued official circulars confirming this special trading day, ensuring that market operations will adhere to standard weekday timings. The pre-open session is designated from 9:00 am to 9:08 am, followed by regular trading in equity, futures and options (F&O), and commodity derivatives segments from 9:15 am to 3:30 pm. However, certain specific sessions, such as the T+0 Settlement Session and auction sessions for settlement defaults, will not be conducted on this Sunday. This strategic move by the exchanges underscores the critical importance of the Union Budget to India's financial ecosystem, allowing investors and market participants to react swiftly to new policies, allocations, and economic directions. The decision aims to maintain market efficiency and transparency in light of such a significant national announcement. Reputable Indian financial news outlets, including The Times of India, Mint, and BusinessToday, have widely reported and corroborated this development, highlighting its significance for the Indian economy and investor community. The broader Budget Session of Parliament is scheduled to commence on January 28 and conclude on April 2, 2026.
