Iran predicts global oil prices to soar by 50 per cent With the sanctions carrying the potential to trigger a deep economic crisis in the country, Iran has responded with a mixture of belligerence and conciliation. That the government of Mahmoud Ahmadinejad, Iran's prime minister, has allowed the inspectors in at all has angered hardliners. Demonstrator met the inspectors at Tehran's airport carrying photographs of a nuclear scientist assassinated in the city earlier this month. Ali Akhbar Salehi, the Iranian foreign minister who is seen as relatively moderate, spoke of his optimism about the IAEA's visit, promising that all the inspectors' questions would be answered. "We have nothing to hide and Iran has no clandestine activities," he said. But the hawkish speaker of parliament, Ali Larijani, was more hostile, threatening that Iran would sever relations with the IAEA if it showed that it was a "tool" of the West. The EU is phasing in its sanctions on importing Iranian oil over six months to allow economically troubled Greece, Italy and Spain, Tehran's biggest European customers, to find alternative markets. By seeking to pre-empt the sanctions, Iran had hoped to prove that the EU would suffer the more painful consequences from an embargo. A pre-emptive step could also cost some European energy firms who have paid for Iranian oil in advance more than a billion pounds But there is little doubt that Iran would suffer too. Although China and India could conceivably take up the excess oil, they would only do so at a heavily discounted price. Ahmed Qalabani, the deputy oil minister, boasted that measures to curtail exports would send oil prices soaring to between $120-150 a barrel, up from $108 yesterday. "We will not leave enemies' sanctions unanswered and we will impose other sanctions on them in addition to closing Iran's oil supplies to Europe," said Mohammed Karim Abedi, a senior Iranian legislator, who added that an ban on oil sales to the EU would last between five and 15 years.
