THE TIME: The Strait of Hormuz has been closed for more than two weeks. Mr Rauball, at what point does the blockade really become critical for the global oil market?

Johannes Rauball: That’s hard to say. We are in an extraordinary situation. The blockage of the Strait of Hormuz leads to strong fluctuations in the Oil price. Iran is using the blockage as leverage to drive up prices and put political pressure on the US. Iran has signaled that it believes oil prices of up to $200 a barrel are possible.
