How much money have U.K. banks created ?

From the time when the Bank of England was formed in 1694, it took over 300 years for banks to create the first trillion pounds. It took only 8 years for banks to create the second trillion. Today cash accounts for just 3% of the total money in the economy (coloured green on the chart below). Money created by banks accounts for the other 97% (red on the chart below).
