Last week, Kuwait bought an office block in the City for £400 million, roughly the income from six million barrels of oil at today's prices. In May 2007, the block would have cost £540 million, roughly the income from 17 million barrels of oil at last year's prices. This 11 million-barrel saving comes from oil prices doubling to $130 a barrel and the price of City property falling by 25 per cent. The beneficiary, in this case, was St Martins, the state of Kuwait's long-time UK property arm. It purchased the new 500,000 sq ft site in Lime Street from British Land.
