“In business contexts, the rate of interest should reflect the current commercial rate. The approach of the commercial court is to award interest at a rate which broadly represents the rate at which the successful party would have had to borrow the amount recovered over the period in question.”
“Thus a rate of 1% above base rate prevailing from time to time has become the practice of the commercial court, albeit this is only a presumption and can be varied up or even down to meet the fairness of the parties’ particular situation.”
“It is right that the defendants who have kept small businessmen out of money to which a court ultimately judges them to be entitled should pay a rate which properly reflects the cost of borrowing by such a class of businessmen. The law should be prepared to recognise, as I suspect the evidence might well reveal, that the borrowing costs generally incurred by them are well removed from the conventional rate of 1% above base, (and sometimes even less) available to first class borrowers. ”
