At the National Commodity and Derivatives Exchange, refined soya oil for delivery in February eased by Rs 1.95, or 0.31 per cent, to Rs 617.40 per 10 kg, with an open interest of 48,770 lots.
Similarly, the oil for delivery in March shed Rs 1.45, or 0.23 per cent, to Rs 616 per 10 kg in 58,830 lots.
Analysts attributed the fall in refined soya oil futures to tepid demand at the spot market against adequate stocks on higher supplies from producing belts.
