Why is it only the US can pay debt by printing?
The common notion for US bond guarantee is that in case US reaches a point where it cannot pay debt, it will inflate away the currency (USD) and pay its debt.
Similarly, why can't other countries do the same. Example, UK central bank can also print more money and pay off its GBP bonds if it reaches unsustainable levels and then stabilize later on.
The difference between the two seem that the impact of US printing money will be felt world wide, while in UK, the impact will be limited to its local economy. What gives here?
In fact US printing money seems worse as it is inflating prices and devaluing things globally. Other countries , if they print money to pay off debt, it might result in temporary local inflation but will eventually cool down right.
