And more likely force the pension funds to invest in worthless government bonds.

The pension funds have been buying government bonds for years but the return since 2010 is zero or even minus, so they have had no income or very little but are still paying out a fortune each year.

Not a good business model. Most are insolvent so when the shit hits the fan any year now all will crash and will have to be "rescued" by the governments who are also all insolvent.
