I get the first bit mate. QE didn't work very well and the greedy banks are most likely at the head of the queue if you're looking for reasons why.
It's the second bit I'm having trouble explaining but in my own head it all seems so straight forward and simple. The £400bn+ released via QE was done via the BOE purchasing debt, mainly Govt gilts. We agree on that.
The BOE now own in theory £400bn+ (subject to price fluctuation), We presumably agree on that.
The BOE is owned indirectly by the Govt. We agree on that.
So the next logical step to take from there is that the Govt owns it's own debt and is paying interest to itself. And when it repays the debt on maturity the payment is actually going back to itself is it not? I think this is the point I'm trying to get across that we don't seem to agree on.
If I'm doing your head in mate just ignore it. I'm happy to be blissfully unconsciously incompetent
