Continuing its upward trend, inflation inched closer to the one-per cent mark at 0.83 per cent for the week ended September 19 due to increase in food and fuel prices. The wholesale price-based inflation was at 0.37 per cent in the previous week compared to 12.13 per cent during the corresponding week a year ago. Among food items, potatoes turned costlier by 81 per cent, pulses by 20 per cent and rice by 17 per cent. However, when seen from a weekly perspective, price rise in essential food items did not appear that sharp except for fish that was up 13 per cent. Other food items rose in the range of one to two per cent or saw a decline.
