Bundesbank President Joachim Nagel has warned of the dangers of a bank run through fake news. Nagel: "We must not rest on our laurels, but must look closely and sharpen up on 'blind spots' in supervision" The case of the Silicon Valley Bank has shown that it is necessary to become faster, said Nagel. He had heard from a colleague from South Korea that a task force of the banking supervisory authority was systematically monitoring social media.
