The European Banking Authority published today its reply to claims by Caius Capital LLP that the European Central Bank (ECB) has breached Union law by not disqualifying the Common Equity Tier 1 (CET1) classification of Unicredit capital instruments due to arrangements involving a transaction known as Convertible and Subordinated Hybrid Equity-Linked Securities (CASHES). The EBA finds that there is no clear evidence of a breach of Union law by the ECB and therefore decided not to open a formal investigation.
