Expect higher prices at the pump

The temperature is rising and so are gas prices. Christine Romans explains why you might be seeing a 20 cent hike on the gallon.

由于气温上升，家庭和公司开始大量使用空调，并消费更多天然气生产的电力，天然气价格将上涨。

卡塔尔国家银行集团（QNB Group）说，石油和天然气在2012年呈相背态势。2012年，全球石油产量增速大大超过消费增速，而天然气需求增长则远超过供应增长。这意味着天然气平均进口价格的增长比油价增长更加强劲。

Brace yourself drivers, for a rise in gas prices, how much? well here is what's happening right now, unrest in Egypt, even the perception of instability in the middle east can raise oil prices and that filters after about three weeks into gas prices, you'll also have concerns about inventories, because of refinery retooling in this country also because in Libya and some other countries, you have reduced output, what does it mean for the price of gasoline? we've already seen gas spike quite quickly this summer, $3.55 is the average for unleaded, you can see that's lower than a year ago, but it has been moving up quite quickly, and what it means it means a lot of analysts think you could see 10-20 cents per gallon pretty quickly added to the price of gas, and that takes money right out of the economy, every penny increase in the price of gasoline, it's $4 million a day out of consumers pockets, let's talk about where prices have been, these are those records, remember right before the financial crisis and then gas prices fell, you can see that over the past several years the peaks have come in the summer, what happens now? you are going to see gas prices increase, but many experts are saying hopefully by September those prices will come down as they have over the past several years.
