The period from the early 1970s up until 2007 marked another watershed. Financial liberalisation took hold in successive waves. Since then, finance has comfortably outpaced growth in the non-financial economy, by around 1.5 percentage points per year. If anything, this trend accelerated from the early 1980s onwards. Measured real value added of the financial intermediation sector more than trebled between 1980 and 2008, while whole economy output doubled over the same period. 2  BIS Review 95/2010  In 2007, financial intermediation accounted for more than 8% of total GVA, compared with 5% in 1970. The gross operating surpluses of financial intermediaries show an even more dramatic trend. Between 1948 and 1978, intermediation accounted on average for around 1.5% of whole economy profits. By 2008, that ratio had risen tenfold to about 15% (Chart 2). Internationally, a broadly similar pattern is evident. In the US, following a major decline during the Great Depression, the value added of the financial sector has risen steadily since the end of the Second World War. As a fraction of whole economy GVA, it has quadrupled over the period, from about 2% of total GDP in the 1950s to about 8% today (Chart 3). Similar trends are evident in Europe and Asia. According to data from the Banker, the largest 1000 banks in the world reported aggregate pre-tax profits of almost $ billion in fiscal year 2007/08 (Chart 4), almost 150% higher than in 2000/01. This equates to annualised returns to banking of almost 15%.
