So why have pump prices gone up in the last week or so? As I've said before, if you watch the commodity markets and follow what happens to crude oil and wholesale gasoline, you'll get a good sense of where the price of gasoline is going to go. The signs clearly pointed up this week.
On Friday, crude oil finished an uphill climb by hitting it's highest level since last November. You can find more here as well. Wholesale gasoline prices also went up, with many citing positive economic news as the reason for the uptick in both. As a result, combined with a smaller build in inventories than expected, upwards movement on the commodity markets have pushed pump prices up across North America.
