OIL CUTOFF? A major union representing Nigerian oil workers said it will shut down all production Sunday as part of a nationwide strike in a country that is important to U.S. oil supplies.
REFINERY REDUCTION: Nigeria is the fifth-largest oil exporter to the United States, supplying 630,000 barrels of crude per day to American refineries.
THREAT IMPACT: It is unclear how large an effect the planned shutdown by the Petroleum and Natural Gas Senior Staff Association of Nigeria will have. Benchmark oil prices on Thursday rose above $102 a barrel on concerns about global supplies.
