Copper prices declined by Rs 1.25 or 0.41 per cent to Rs 306.50 per kg in futures trade today, as traders reduced their positions on the back of a weakening global trend.
Weak trend at physical markets due to subdued demand also weighed on the copper futures prices.
At the Multi Commodity Exchange, the copper for delivery in current-month June contract declined by Rs 1.25, or 0.41 per cent to Rs 306.50 per kg, with an open interest of 25,507 lots.
The metal for delivery in August contract also traded lower by Rs 1.25, or 0.40 per cent to Rs 310.05 per kg, with a business turnover of 5,464 lots.
Analysts attributed the fall in copper futures to a weakening trend at the London Metal Exchange, where a firming dollar weighed on the metal.
Besides, subdued trend at domestic markets also put pressure, they added.
Meanwhile, the metal for three-month delivery shed 0.36 per cent to $6,626 a metric tonne on the London Metal Exchange.
