Is this Realistic?

The Bank of England has an inflation rate target that has been percieved as unrealistic and limitting as it could lead to higher rates of unemployment and/or even interest rates increasing. 

The Telegraph quotes

'The inflation target would be credible if economic agents believed the Bank would stick to it, even if doing so might lead to recession or unemployment. But few people believed that before forward guidance was issued. Now it seems like there may be rising inflation scenarios that would trigger interest rate rises, and so markets think the average “expected” rate of interest is now higher.

And so they should, for recent economic data suggest recovery is now well under way and the medium-term policy risk is that the Bank will raise rates too little too late, not that it will raise rates too soon.'
