Travers Smith was reacting to an analysis by Reuters of data from the Office for National Statistics on average incomes in areas where bank branches have closed since 2015.
Reuters found that more than 90 percent of the closures were in areas of the UK where the average household earns less than US$39,042 (£27,600) a year.
HSBC, Royal Bank of Scotland, Barclays and Lloyds Banking Group are among banks that have cut 600 branches from April 2015 to April 2016. And while banks shut their doors in poor parts of the country — five out of eight branches opened up in the richest parts of the UK, including Chelsea, Canary Wharf, St Paul's, Marylebone and Clapham — all in London.
Banks blame falling revenues and a rise in mobile and online banking for the need to reduce staff and shut branches in places where they don't have many customers.
The lack of regulated banks operating in deprived areas has led to concerns revealed in a study by Nottingham University of a "growth of 'predatory lending' institutions targeted at poorer customers" moving in.
Wales, and in particular western Wales and the Valleys, has the highest level of poverty in northern Europe, according to 2013 European Union stats. The analysis by Reuters found that big banks were three times more likely to shut a branch in southwest Wales than in the southeast of England, or London.

Royal Banks of Scotland (RBS), owned by the British taxpayer, was found to have closed the most UK branches overall in the last year.
