French covered bonds and EU-Bonds have moved through the OAT, while EDF has narrowed against France without crossing it. These different paths raise a portfolio question: when a sovereign no longer anchors the assets that used to price off it, what becomes the reference point?
Three tests of the old hierarchy
The paper compares direct yield differences with the French sovereign curve and changes through 2026. It also revisits Spanish cédulas in 2011: covered bonds can decouple from a stressed sovereign, but their link to banks and collateral creates a different point of vulnerability.
French covered bonds
A Crédit Agricole covered bond crossed through the OAT in March, as its yield relationship with France changed.
EDF
The corporate line compressed against its matched French tenor, yet still trades above it.
EU-Bonds
Collateral treatment, repo and futures support an issuer that is gaining a sovereign-like market structure while index inclusion remains unresolved.
The risk of recoupling
What bank capital, funding and residential collateral would mean for a position built on covered bonds outperforming France.
