The dawn of euro defence bonds?
The Centre for European Reform said last month that bond issuance for defence was feasible and had many upsides. In particular, they noted that a 500 billion euro fund at current yields would generate an annual interest bill of less than 20 billion euros.
"Since everyone would be on the hook to repay the debt, it could also reduce countries free-riding on the defense capabilities of rapidly ramping-up peers like Poland," it said.
