JPMorgan Chase (NYSE:JPM) has claimed the top spot in the Bloomberg 20, the media company's annual rankings of investment banks by the amount of total fees collected. In 2012, JPMorgan raked in just under $4 billion in such monies -- 25% higher on a year-over-year basis -- to take the No. 1 position.

This is far from the bank's first title. It has led the Bloomberg 20 in four of the past five years.
