A European Safe Asset? Not Without the Investors

econ.columbia.edu2025-11-10Paper
Executive summary

A new study finds that European Union bonds, despite their top AAA rating and joint backing by member states, are not treated as true safe assets by financial markets. These bonds pay higher interest than similar German bonds, not due to credit risk but because their supranational legal status keeps them out of major bond indices. This limits their investor base and makes them more volatile, especially during crises, challenging the idea that more EU debt alone creates safety.

What it examines

This paper studies why European Union (EU) bonds, despite being safe and jointly guaranteed, pay higher interest rates than similar government bonds. Using data analysis and asset pricing models, the authors show that EU bonds' legal status and exclusion from major bond indices shrink their investor base and raise their borrowing costs.

What it concludes

The study finds that EU bonds cannot become true safe assets without legal reforms granting them sovereign status and broader index inclusion. Simply increasing issuance or regulatory tweaks won't close the spread. These findings impact EU financial policy and suggest the euro will struggle to rival the dollar as a global reserve currency.
