In the first half of this year, average retail prices of gasoline and diesel fuel rose on the same period last year by 17.3% to 15.29 lei/l and 24.7% to 14.30 lei/l, respectively. The retail price of liquefied gas rose by 11.8% to 7.38 lei/l, the National Energy Regulatory Agency reported in a press release. The Agency attributes the increases to higher import prices which, in turn, was due to higher oil prices on global markets. In January – June 2011, the average price of Brent oil rose on the similar period last year by 40.9% to $110.9 a barrel, and average Platt's prices of gasoline and petrodiesel rose by 37% to $989.21 a tonne and by 45% to $958.2 a tonne, respectively. However this didn't result in a reduction in imported amounts. On the contrary, gasoline imports rose by 5.5% and petrodiesel imports by 27.5%. Romania accounts for the largest shares of imports, 63.3% and 53%, respectively.
