I find that most sources describe quantitative easing in an overly complicated way that obscures what it basically means.
As far as I understand a central bank is a public entity owned by a state, so I don't see much point in distinguishing a state entity from a central bank entity.
Therefore, I tend to find that the traditional descriptions like "the central banks buys government bonds from private banks in order to inject money in the economy" are ridiculously convoluted and funny.
As far as I understand, if I have a government bond, it is a promise that the state will pay me back some money at some point. So when I'm hearing "the central bank buys government bonds", all I'm hearing is actually "the government is printing cash from nothing to pay me right now, and destroy its debt".
Is my interpretation correct? Why isn't my interpretation the standard official intuitive explanation of quantitative easing? Is it just for newspapers and bankers to sound "serious"?
