This led to assets under management for the company falling by 4.8 per cent to £176.9bn down from £185.8bn.
The firm released the figures in its pre-close trading update this week and said the loss was due to “volatile global markets.”
The firm saw an increase in its equity fund range with customers adding £300m to its global emerging market and global equities strategies to offset weaker UK and European stock markets.
Alternative investment strategies dropped from £28.4bn to £26.2bn but the firm said it remained confident of the performance over the medium to long term.
Martin Gilbert, chief executive of Aberdeen Asset Management, said: “There is no easy resolution to Europe’s sovereign debt problems and the expectation is for anaemic economic growth in the West for some time.
“However, Aberdeen’s approach and broad product range means we are well placed to meet the needs of our clients around the world in this difficult environment.”
Despite the outflow, it is hoped that when it releases its full year results later this year, Aberdeen’s profits and operating profits will be at the top of analysts’ forecasts.
Analysts have predicted a range of £262-£297m profit.
Results for the full year ending 30 September will be released on 5 December.
