“The relevant principles are not contentious. The rate of interest is at the discretion of the court. Secondly the purpose of an award of interest is fairly to compensate the recipient for being deprived of money that he should have received. Thirdly a “broad brush” approach is taken to determine what rate of interest is just and appropriate. As Andrew Smith J put it in Fiona Trust and Holding Corporation and Others v Yuri Privalov and Others[2011] EWHC 664 (Com) at para. 16: “… it would neither be practical nor proportionate (even in a case involving as large sums as these) to attempt a minute assessment of what will precisely compensate the recipient. In particular, the courts do not have regard to the rate at which a particular recipient of compensation might have borrowed funds. This policy is adopted in order to control the extent of the enquiry to ascertain an appropriate rate: see Banque Keyser … the court will, however, consider the general characteristics of the recipient in order to decide whether to assess interest at a rate that is higher or lower than is conventional. So, for example, in Jaura v Ahmed[2002] EWCA Civ 2010 , Rix LJ awarded interest at the base rate plus 3% to reflect that “small businessmen” had been kept out of their money and in recognition of the “real cost of borrowing incurred by such a class of businessmen”
