Four banks — including HSBC — have been fined more than £100 million after traders shared sensitive information with each other in the years following the financial crisis.

The Competition and Markets Authority (CMA) said traders at the four banks used one-to-one chat rooms to discuss UK Government gilts they were buying and selling between 2009 and 2013.
