It’s Pride Month, which draws attention to how companies – including those in finance – treat their lesbian, gay, bisexual and transgender staff. But while the world's investment banks are engaging with employees, other areas of finance have been slow on the uptake, according to the leading LGBT charity.

June commemorates the 1969 Stonewall riots in the US, which served as a tipping point for the Gay Liberation Movement in the country, and is now observed globally - including by some of the world's biggest banks. Earlier this month, Goldman Sachs flew a rainbow flag outside its London office to mark the occasion, while last year Barclays turned a number of its cash machines into 'GAYTMs' for London's Pride parade.
