"The fact it's been a little bit sticker than we hoped this month really casts further doubt on the Bank's projection."
Others were less concerned.
"We thought the risks were that it would be a bit above the consensus, but in the scheme of things it's pretty much in line," said Ross Walker, RBS economist.
