An increase in prices of essential commodities continues to pinch consumers, which dampens the festive spirits in Tripura. Prices of pulses, edible oil, vegetables, fish, and eggs have remained firm for the past few months mainly due to a rise in demand and bottlenecks in the supply chain, traders of the city agartala, said on Sunday. They added that prices of pulses and edible oil rose by 15- 20 per cent, while most vegetables are sold at over Rs.60 a kg. Onion, which was sold below potato price at Rs 30 per kg recently, is now available at Rs 40-50, while egg price has increased from Rs 7 a piece to Rs 10. Volatility in commodity markets happens every year but it used to be temporary. This year, prices are ruling high for last few months,” a vegetable seller said. “Prices of vegetables are likely to pinch till December end till new crops of vegetables start arriving in market. At present, vegetable is supplied from local areas” added he.
