“With inflation expected to remain below the Bank of England’s central target of two per cent until 2017, we think the Bank Rate will remain on hold until the middle of next year.

It forecasts economic growth to decelerate to two per cent in 2016, from 2.5 this year, and then average just 1.7 per cent between 2017-2020.
However, the Office for Budget Responsibility expects growth to stay above two per cent until 2020.
In the US, the Federal Reserve cited similar concerns over global economic health for not raising its interest rates at its September meeting, holding them at 0.25 per cent.
