【明報專訊】THE LATEST REPORT the Consumer Council has released says an analysis of data of international crude oil prices and auto-fuel prices over the past two years available to the public shows that at certain times oil companies were quick to put prices up but slow to bring them down. Similar investigations were made. However, the latest was different. In it the Consumer Council got hold of such data as to allow it to point out that a quick rise and a slow fall occurred respectively in the first half of 2013 and the second half of 2014. The former took place four days after international crude oil prices had gone up, and the latter, eight days after they had come down. The report also says that the five oil companies have adjusted car-fuel prices in similar modi operandi. They each adjusted prices 55 to 60 times in the 24-month period.
