The possibility of Britain leaving the EU is the "biggest domestic risk to financial stability", Bank of England governor Mark Carney has said.
Mr Carney emphasised the Bank was not taking sides in the EU referendum.
But Conservative MP Jacob Rees-Mogg accused him of making "pro-EU" comments.
The governor told the committee that an exit posed the biggest "domestic" risk in part because there could be uncertainty over such things as investment, household spending, and the impact on sterling.
Mr Carney said: "It is the biggest domestic risk to financial stability. I would say that in my judgement the global risks, including from China, are bigger than the domestic risks."
However, he told the committee that continued EU membership brought risks as well. "The principal risk - risks, I should say, because there are more than one - are associated with the unfinished business of European Monetary Union," Mr Carney said.
