The social housing regulator has admitted that it had six housing associations on its "watch list".
Peter Marsh, chief executive-designate of the Tenant Services Authority, said that, as a result of problems caused by the credit crunch, half a dozen housing associations were presenting more risk than usual.
Appearing before the Communities and Local Government Select Committee, he said: "There are six housing associations on our watch list.
"They are not in intensive care; however, they are subject to more regulatory scrutiny than normal."
He said this included the TSA taking a weekly look at their cashflow and engaging regularly with their chief executives.
When asked if any of them were large housing associations, he said a "small number of them are medium-sized to large", but he stressed that there were only six that the TSA had concerns about, out of 250.
