“I cannot accept that there does not exist an expertise in the practice of banks in selling IRHPs to retail customers. A distinction does need to be drawn between evidence of accepted practice which is admissible, and evidence which amounts to no more than the expert’s opinion of what he or she would have done in the circumstances, which is not admissible. But the sale of derivatives by banks to individual customers as a hedge for loan transactions, although a comparatively new phenomenon, has been recognised as highly regulated activity over the past 10-15 years. It is a specialist niche in lending by the major banks, for which their employees have, or ought to have been, specially trained. I am presently satisfied that there is, or is likely to be a body of practice that has grown up in the banking industry as to how these derivatives should be sold, and that there is a broad division in such practice between sales to retail customers and sales to professional customers and market counter-parties. To that extent, I am fortified in this conclusion by the fact that the parties in the swap cases, where I have already directed that there should be expert evidence, appear to have had no difficulty in identifying individuals able to give the relevant expert evidence.”
“The risk in excluding expert evidence of the type I have described is that the court determines what is and is not good enough to meet the standard required by the relevant COBS rule in a vacuum which is filled only by the parties and submission. In my judgment, a court ought to be slow to hold that a bank acted in breach of its statutory duty, and or was negligent on that basis.”
“The expert should be asked to give evidence on whether the Defendants’ actions or inactions fell below the standard of practice reasonably adopted in the banking industry, including by reference to its regulatory obligations, with respect to the sale of interest rate hedging products to private customers in respect of the 2006 swaps and to retail customers in respect of the 2007 swap, those terms being terms (reading to the words) ... under the regulatory rules.”
