“When damages are assessed in pounds sterling the conventional rate of interest that is awarded in commercial cases is “base rate plus 1%”
“My attention has been drawn to one authority which is relevant to the issues I have to determine, and that is the decision of Leggatt J in VIS Trading Co Ltd v Nazarov ... The relevant part of the judgment starts at para 9, where Leggatt J cites from the relatively well-known decision of Fiona Trust and Holding Corp v Privalov … Leggatt J observed that Andrew Smith J had noted a different practice in relation to arbitrations where LIBOR was more commonly used as a benchmark rate, and then he concluded at para 14 as follows: ‘In my view, the six-month US LIBOR rate is a more appropriate rate to use as a benchmark in a case of this kind than the US prime rate for the reason already indicated that LIBOR has become the most widely used benchmark outside the United States for lending denominated in US dollars. That is so not only in the shipping field but generally in international commerce …’ I respectfully concur with that analysis, which reflects my experience in the Commercial Court and the London Circuit Commercial Court. For those reasons, I conclude that in principle the appropriate base rate is the six-month US LIBOR rate.”
“The task of the court is to choose an interest rate it considers will be a realistic reflection of the cost of borrowing for a claimant such as Swindon, in the absence of evidence seeking to prove its actual borrowing costs (since no such evidence was provided). Given the factors set out in the previous paragraph, I consider that US Prime + 2%, as proposed by the claimants, is such a rate. The defendants proposed US$ libor + 2½%. It suffices to say that there is no presumption or practice favouring the use of US$ libor over US Prime. If anything, the court has for some time now tended to accept that US Prime represents more realistically than does US$ libor a base line for real-world US$ borrowing costs, at all events away from the world of major financial institutions or other businesses of that sort of magnitude.”
