Fewer than one in five institutional infrastructure investors have committed money to a new infrastructure fund this year. These funds are trying to raise $115bn (€77bn) from investors; but weak demand raises questions about whether or not they will reach target size.

A survey conducted by alternative assets research firm Preqin found that 81% of investors have not made any new commitments in 2009, 14% have invested in one fund and 5% have invested in more than one fund.
