Barclays Wealth has strongly advised clients invested in a troubled AIG money market fund to retain their investment until July 1 2012, and has set up a facility that allow investors holding to maturity to borrow up to 100% of their investment's guaranteed value in a bid to stop a fire sale of assets.

Financial News reported last week that Barclays Wealth managing director Mark Kibblewhite had agreed to send on a letter on Friday to clients outlining the bank's attitude to their potential losses on the fund after meeting representatives of a lobby group.
