That's just because all the bonds are bought by the government's themselves using printed money. It doesn't actually mean Europe is in a good position financially. Inflation is rising fast and had the potential to cause ruin. Of all times it is blue that Europe is financially wrap and unable to respond, thanks to our society being unable to detect academic pseudoscience.
Printed money is also cheap as long as inflation is low.
For example it took trillions in unexpected spending to bump US inflation above the target 2%.
And yields are going to remain low because of the aging population of the "west" put their pension into stable assets, and pension funds will buy gov. bonds.
