The level of competition in investment and corporate banking services are to be investigated by the UK’s financial regulator, the Financial Conduct Authority (FCA).
Launching its first review of the sector, the FCA said that the potential benefits of improvements could be high.
It said there was “limited clarity over price and quality of services”.
And it said that could make it difficult for clients to assess whether they were “getting value for money”.
“We have chosen this particular area because the benefits of effective competition in the market could be significant,” said Christopher Woolard, director of strategy and competition at the FCA.
