HSBC.

In 2011, traders at HSBC Holdings Plc got a big order to buy $3.5 billion worth of pounds sterling for a corporate client at the 3 p.m. fixing price. "Ohhhh, f***ing Christmas," responded HSBC trader Mark Johnson. (To his colleague, I mean. They kept a straight face to the client.) HSBC proceeded to buy sterling in the minutes leading up to the 3 p.m. fix, pushing up the price. By the time of the fix, that price was pretty high -- higher than the average price HSBC had paid -- and it was able to sell the client the pounds it had bought at a big premium, making about an $8 million profit. Years later, U.S. authorities decided that this was a crime, and charged Johnson with that crime, and yesterday he was convicted of the crime.
