State Street reported this week that 59% of institutional investors globally intend to raise their allocations to private equity over the next five years.
However, they insist on more transparency from managers, and 28% said that if they do not get it, they will cut back on their investments.
State Street's findings were based on a poll conducted in December of 118 institutional investors.
Private equity assets hit a new high of $2.4 trillion in June, according to State Street.
Seventy percent of investors surveyed demanded increased levels of transparency from private equity managers on the performance of the underlying assets in each portfolio.
Forty-six percent wanted greater read-through on risk exposures, 32% on net asset values and 23% on fund cash flows.
