The potential cutbacks are part of a growing need for the commercial lender to reduce its current financial exposure in order to protect its future.
Managing director of InterBay, Colin Bell, said: "Many mortgage lenders have already taken corrective action and many more will do so in the coming weeks, but that does not make our decision any easier.
"Over the next few days we will be speaking with our key partners to ensure we continue to support them and give them excellent service.
"We have to manage our business volumes and we will do this by reviewing our product and focussing our efforts on key business partners. Intermediaries will understand that lenders have to be more cautious during this period of uncertainty.
“Overall we believe that this course of action allows us to take time to prepare for the market’s return so we and our key partners are best placed for continued success when it does”.
