The value of the British pound against the U.S. dollar is at a 31 year low. With some economists not writing off the chances of sterling reaching parity with the dollar, the infographic below shows the company with which the UK currency is now sharing.

On the flip side, the Brazilian real saw gains of almost 24 percent alongside the buoyant ruble at 16 percent.
