Nifty too dipped below the key 8,100-level.
Sentiment also took a hit on sustained foreign capital outflow from emerging markets, including India, and the dollar climbing to its highest mark in over 13 years.
Trading sentiment remained distinctly weak due to cash crunch arising out of the government's move to demonetise Rs 500 and Rs 1,000 notes to flush out black money amid concerns about its impact on small and medium-sized businesses which largely run on cash.
However, it turned volatile largely in tandem with overseas markets and slipped into negative terrain to hit a low of 26,155.40 before settling 71.07 points, or 0.27 per cent, lower at 26,227.62, a level last seen on May 25, 2016.
The Nifty, after shuttling between 8,151.25 and 8,060.30, concluded 31.65 points or 0.39 per cent down at 8,079.95, a level last seen on May 26, 2016, when it closed at 8,069.65.
