Manchester Building Society is fighting for survival after making a £4.9m loss in 2015.
In a statement the society said there was “material uncertainty” regarding the long-term future of the society.
The society is winding down its mortgage book and is offering no new loans.
David Harding, chairman of Manchester Building Society, said: “Although there is uncertainty regarding the long-term future of the society, we continue to put the best interests of our members first.
“The board is developing a number of options which individually or in combination are reasonably expected to secure the future of the society, to enable it to continue to meet capital requirements and to improve the quality of its regulatory capital."
Manchester has 4,000 mortgage borrowers and 18,000 savings accounts on its books.
