Middle East Supply Debate On Tuesday, Iran’s vice president said his country was ready to close the Strait of Hormuz if western nations embargoed the country’s oil because of its ongoing nuclear programme. The head of the country’s navy added yesterday that his fleet could block the strait. A Saudi Arabian oil ministry official said that Saudi Arabia and other Gulf producers were ready to provide more oil if Iran tried to block the strait. He didn’t specify other routes that could be used to transport oil, although they would probably be longer and more expensive for getting crude to the region’s customers. Relations between Saudi Arabia and Iran have soured significantly in recent months, though a recent meeting of the oil producer’s cartel, Opec, in which the two are leading members, ended in an agreement to maintain output at current levels. Iran is the world’s fourth largest oil producer, pumping 4 million barrels a day, and oil exports make up 80 percent of Iran’s income.
