EU Banking Union 2026: Inside the CMDI Reform
On 5 March 2026, the Council of the EU formally adopted the long-negotiated Crisis Management and Deposit Insurance (CMDI) reform package, following the political agreement reached with the European Parliament. The reform tightens the rules resolution authorities must follow before reaching for ordinary insolvency, recalibrates how deposit guarantee schemes fund resolution and preventive measures, and reforms the Single Resolution Board's governance. Member States now have 24 months from entry into force to transpose the BRRD and DGSD amendments into national law — a live implementation window that puts pressure on every institution and authority operating inside the Banking Union to understand not just the new rules, but how they interact with the architecture already in place.
That architecture is exactly what EU Banking Union: Law, Institutions, and Co-operation, edited by Jonathan Bauerschmidt, Raffaele D'Ambrosio, Diane Fromage, Daniela Jaros, and Paul Weismann, sets out to map in full. Rather than treating supervision, resolution, and deposit protection as separate silos, its twenty-three chapters trace how the ECB, national authorities, the Single Resolution Board, and EU courts actually cooperate — and where the gaps and friction points sit.
Three places where this plays out in practice: a resolution authority weighing whether a smaller, non-systemic bank should go through BRRD resolution or ordinary insolvency now has a direct reference for how SREP findings, MREL requirements, and deposit guarantee scheme triggers are meant to interact under the reformed sequencing rules. A compliance team advising a bank with EEA/EFTA or Swiss operations can work from the book's dedicated chapters on how those jurisdictions sit inside or outside the Banking Union, rather than piecing it together from separate country guides. And anyone briefing a board on supervisory accountability has a single chapter mapping how the SSM and SRM answer to the European Parliament and the European Court of Auditors.
For law libraries and university collections building out EU financial regulation holdings, this is a reference that should stay current through the CMDI transposition period rather than needing replacement once national implementing laws land, because its focus is the durable institutional architecture rather than a single legislative text.

Q&A
Q: What changed with the CMDI reform adopted in March 2026?
A: The Council formally adopted amendments to the BRRD, SRMR, and DGSD that tighten when resolution authorities must act, simplify and cap the least-cost test for deposit guarantee scheme funding, and add sequencing and burden-sharing rules — with national transposition due within 24 months.
Q: Does this book explain how the new CMDI rules interact with existing Banking Union supervision?
A: Yes — chapters on SREP, MREL, and capital requirements sit alongside the institutional and cooperative chapters, so the reformed resolution triggers can be read against the existing supervisory framework rather than in isolation.
Q: Who actually supervises a bank inside the Banking Union — the ECB or the national authority?
A: The book devotes a chapter specifically to how national law is applied by the ECB and how EU bodies divide supervisory responsibility, rather than treating it as settled.
Q: Are Switzerland and non-euro EU states covered, or only eurozone banks?
A: Both — separate chapters address close cooperation arrangements for non-euro-area EU member states, the position of EEA/EFTA states inside the internal market but outside the Banking Union, and Switzerland's distinct relationship with the framework.
Q: Where can I buy EU Banking Union: Law, Institutions, and Co-operation?
