"One of the biggest economic experiments of our age is coming to an end. The United States Federal Reserve has called time on 'quantitative easing' (QE), a policy that has pumped trillions of dollars into the US financial system.

"The jury is still out - and will be for a long time - on whether it has worked. There are real anxieties about what the consequences will ultimately be.

"... QE may be ending, but we can be sure the debate about its impact will not. Has it saved the US, and perhaps the rest of us, from economic disaster? Or has it sowed the seeds for the next financial crisis?"
