It's almost five years since the Bank of England launched its quantitative easing programme, also known as QE.

So I think it's a good time to recap what the programme actually is and also look at whether it's worked.

So what is QE?

Put simply, the Bank of England created money, which it then used to buy gilts from the commercial banks such as HSBC and Barclays.

The Bank did this to achieve these objectives:

The first was to stop deflation. Back in 2009 there were fears that we could have deflation where prices would fall across the economy.

By creating extra money, the Bank could reduce those deflationary pressures.

The second objective was to reduce long-term interest rates. The Bank of England normally has the greatest control over short-term rates; that's for loans that last for days, weeks, or months. The longer the loan, the less influence the bank has.

Instead long-term interest rates are basically set by investors in the gilts market. If investors push up the price of gilts, the yield falls and long-term interest rates across the economy should move down too.

By buying gilts, the Bank of England has reduced gilt yields and long-term interest rates.

So has QE worked?

It's impossible to give a definitive answer on this as we don't know what would have happened without QE.

But the reality is we haven't had a slump, and we haven't had deflation, and I suspect things might have been different without QE.

On the other hand, QE has also had some negative impacts. Asset prices, especially property and shares have shot up as more money has become available. Rising asset prices have been good for the wealthy not for the rest of us.

QE has also hurt savers because interest rates have been so low and rates on annuities have also been amazingly low.

My hunch is that QE was necessary in the first place but has perhaps been in operation for too long.

Anyway, we appear to be entering the end game' on QE in at least the US and UK. In the US, there's much talk about the taper.' So in my next video I'm going to look at the taper and how QE may be wound down.
