Prices of petroleum products at the pumps could go up again by the end of next month if the trend on the international market continues.The commodity is currently priced above the 100 dollar barrel mark, a situation being attributed to the political crisis in Egypt where a significant amount of crude transits through the Suez Canal.According to the National Petroleum Authority a price increase would be justified because the current pump price is based on a world market price of between 90 and 95 dollars.Chief Executive Alex Mould however explained the NPA will continue to monitor the trend.Source: Joy Business/Ghana
