On 1 February 2013, he nationalized the financial institution SNS Reaal, preventing its bankruptcy. Shareholders and owners of subordinated debt are expropriated with no compensation and others banks of the country have to contribute to the takeover up to one billion euros. By December 2013, Dutch press named Dijsselbloem politician of the year, describing him as "intelligent, balanced and good at finding compromises". In a response, he said that he was surprised about winning the prize because he "does not work on the forefront".
On 21 January 2013, Dijsselbloem took office as President of the Eurogroup, a grouping of the Ministers of Finance of the Eurozone, those member states of the European Union (EU) which have adopted the euro as their official currency; he succeeded Jean-Claude Juncker. Spain was the only country not to back his candidacy.
Dijsselbloem struggled early in his two and a half-year term and faced criticism for his handling of the "Cyprus bail-in." In March 2013, he took the lead in the negotiation, conclusion and subsequent public promotion of the bailout. He attracted criticism for the precedent of taking depositors' balances as part of bank rescues but said "I am pretty confident that the markets will see this as a sensible, very concentrated and direct approach instead of a more general approach... It will force all financial institutions, as well as investors, to think about the risks they are taking on because they will now have to realise that it may also hurt them."
On 24 March 2013, the Financial Times and Reuters reported that Dijsselbloem saw the Cyprus bail-in as a template for resolution of a bankruptcy. However, it was the interviewer that had used the word "template" and not Dijsselbloem himself. On 26 March 2013, Dijsselbloem said explicitly that he did not consider the Cyprus case to be a template.
