What is Quantitative Easing (QE) and how does it affect the Pound?

In extreme situations, the Bank of England can enact a policy called Quantitative Easing (QE). QE is the process by which the BoE substantially increases the flow of credit in a stuck financial system. QE is a last resort policy when lowering interest rates will not achieve the necessary result. The process of QE involves the BoE printing money to buy assets – usually government or AAA-rated corporate bonds – from banks and other financial institutions. QE usually results in a weaker Pound Sterling.
