NPR's business news starts with a spike in gas prices.
Gasoline prices jumped 18 cents over the last couple of weeks. That's the biggest increase so far this year. The Lundberg Survey shows that heading into the weekend, the national average price of a gallon of self-serve was $3.69. Now, analysts say the spike is in part because of some refinery and pipeline issues around the country.
Wholesale prices fell 1 percent in May from April thanks to an 8.9 percent plunge in the price of gasoline, the Bureau of Labor Statistics reports. The overall decrease is the largest in one month since July 2009.
Excluding the energy and sectors, prices at the wholesale level ticked up 0.2 percent.
In Texas recently there was a grand opening for what is now the largest refinery in the U.S. Shell and Saudi Arabia's national oil company, Saudi Aramco, have more than doubled the capacity of their Port Arthur refinery.
The refinery business has been going through a tough period in recent years. Americans are buying less gasoline and other petroleum products — about 10 percent less than in 2005, according to the U.S. Energy Information Administration.
