The Office of Fair Trading has launched an extensive review of the personal banking sector, looking at the transparency and value of personal current accounts to consumers as a whole. Of particular interest to the watchdog are the charges which are being levied for unauthorised overdrafts and returned items. OFT Chief Executive John Fingleton commented: "Our ultimate objective is a competitive retail banking market in which informed and active consumers drive strong competition and high levels of customer service among banks long-term, with minimum regulatory intervention." Submissions should be made to the OFT in writing before 30 June 2007.
