The Indian stock market, comprising the Bombay Stock Exchange (BSE) and the National Stock Exchange (NSE), is set to conduct a full trading session on Sunday, February 1, 2026. This unusual move has been announced to coincide with the presentation of the Union Budget for 2026-27 by Finance Minister Nirmala Sitharaman on the same day. The decision ensures that investors and traders can react immediately to the government's financial plan and policy announcements, which are expected to influence market sentiment significantly. According to circulars issued by both exchanges, the trading hours will adhere to the standard market schedule. The pre-open session will begin at 9:00 AM and conclude at 9:08 AM, followed by normal trading in the equity market from 9:15 AM to 3:30 PM. While most segments will operate as usual, certain specialized sessions, such as the T+0 Settlement Session and Auction Session for settlement default, will remain suspended. The presentation of the Union Budget on a Sunday, February 1, 2026, is a rare occurrence, marking the first time since 2000 that the annual financial statement will be delivered on a Sunday. This also makes it one of the very few instances in recent memory where Indian stock markets will operate on a Sunday. The decision has been widely reported by credible Indian financial news outlets, including The Times of India, Mint, NDTV Profit, and Hindustan Times, all corroborating the special trading schedule. Finance Minister Nirmala Sitharaman is expected to present her ninth consecutive Budget, making it a closely watched event for fiscal policy and economic reforms.
