The Bank issued the warning last week – as it hiked interest rates to 2.25 per cent, their highest level for 14 years – but the prime minister argued it was not her responsibility.
Speaking to CNN in the United States, Ms Truss also dismissed suggestions of a referendum on Irish reunification now that Catholics outnumbered Protestants in Northern Ireland.
She insisted she wanted a “negotiated solution” of the Northern Ireland protocol, while indicating she would not back down over the conflict, which threatens a trade war with the EU.
The prime minister was also asked about her apparent championing of “trickle-down economics” – the theory that handing big gains to the rich will benefit all, which has been condemned by Joe Biden.
She told CNN’s State Of The Union programme: “We all need to decide what the tax rates are in our own country, but my view is we absolutely need to be incentivising growth at what is a very, very difficult time for the global economy.”
But asked about the Bank of England’s warning that the UK might already be in a recession, Ms Truss replied: “That’s a matter for the Bank of England.”
The Good Friday Agreement states that a unification referendum should be called if it is “likely that a majority of those voting would express a wish that Northern Ireland should cease to be part of the United Kingdom”.
But Ms Truss, asked whether she thought it was just a matter of time before that referendum was staged, replied: “No, I don’t.”
On the protocol, she argued: “What’s important is that we protect and respect the positions of both the nationalist community in Northern Ireland, as well as the unionist community in Northern Ireland.
“So what I want to do is find a way forward, and my preference is a negotiated solution with the EU that protects that north-south relationship, but also protects the east-west relationship, and that is absolutely core to the Belfast Good Friday Agreement.”
Asked whether countries might leave the Commonwealth after the Queen’s death, Ms Truss said: “It’s a decision for any country about how they decide to organise themselves.”
But she added: “I think the Commonwealth is a force for good. It’s a believer in freedom and democracy and we need more of that in a world where we are facing these authoritarian regimes who want to subvert those ideas.”
