The economic plight of nations weathering aftermath of communism's collapse is contributing to sagging world oil demand. IEA predicts oil demand in eastern Europe will fall this year to 1.38 million b/d from 1.69 million b/d in 1990. Previously, demand had been steady at about 1.8 million b/d. The biggest demand declines have been in Romania, Bulgaria, and Yugoslavia. Only Hungary shows signs of a moderating demand slide.
