Exorcising eurozone ELA as we know it

Yes the IMF calls for common eurozone deposit insurance, in this new banking union paper. But also look at what they suggest on emergency liquidity assistance:

Lender of last resort. The lender of last resort makes liquidity support available to solvent yet illiquid banks. Centralizing all LOLR functions at the ECB would in the steady state eliminate bank-sovereign linkages present in the current ELA scheme (see Box 1). This would require changes to the ECB’s collateral policy, as by definition euro area banks that tap ELA cannot access Eurosystem liquidity owing to collateral constraints. Until such time as all banks are brought under the ECB’s supervisory oversight, ELA would be sourced through both the ECB (for banks brought under its purview) as well as national central banks (for banks that remain under national supervision, albeit with adjustments made to the national ELA limits).

Which would be nothing short of a revolution.
