Banco Popular, a Spanish bank, made worldwide headlines following its forced overnight sale to Banco Santander for €1. The sale, which was executed after a decision by the E.U. Single Resolution Board, was widely greeted as a successful application of the new E.U.-wide resolution scheme, with little sign of contagion within the market. The shareholders that had the value of their shares wiped out, along with the holders of €2 billion worth of bonds, are likely to have a different perspective, however. In a guest article, Cadwalader partner Steven Baker and associate Jenna Rennie review the E.U. resolution framework for banks and its application to Banco Popular; examine the viability of legal challenges by investors whose investments were wiped out by the resolution; and discuss how hedge funds can apply lessons from Banco Popular’s collapse to future investing in the European banking sector.
