From New York Times:
"Italy’s prime minister, Matteo Renzi, only 41, once seemed to have solved the riddle of how to survive Europe’s populist, anti-establishment tempest. But with a critical national referendum on Sunday, the populist wave is now threatening to crush him and plunge Italy into a political crisis when the European Union is already reeling. 'The problem with Italian banks is they are fragile and they are really big,' said Ángel Talavera, senior eurozone economist at Oxford Economics in London. 'Banks of that caliber, as soon as you have any noise and rumors, it creates a really bad loop.'"
