Financial institutions have traditionally wanted to create a feeling of stability and trust, but more recently some consumer banks have opted for a feeling of vibrancy and energy. Either way, banks et al. therefore spend a great deal of time and money on their branding: cool, dark colors and serif fonts for the traditional logos, and warmer, brighter colors and sans serif fonts for the modern.
From http://fontmeme.com/logo-fonts/finance/, some traditional marks:
Merrill Lynch font here refers to the font used in the logo of Merrill Lynch, which is a financial services provider and now the wealth management division of Bank of America.
The font used for the logotype of Merrill Lynch is probably Aachen Bold designed by Colin Brignall in 1968 for Letraset. The font is a commercial one and you can view more details about it here.
London Stock Exchange
London Stock Exchange font here refers to the font used in the logo of London Stock Exchange, which is a stock exchange located in London, United Kingdom.
The font used for the logo of London Stock Exchange is probably Vectora, a contemporary sans serif designed by Adrian Frutiger for Linotype-Hell in 1991.
