The euro zone bank sell-off was also exacerbated by a report in the Financial Times that the European Central Bank is increasingly concerned about some lenders, particularly BBVA of Spain, UniCredit of Italy and BNP Paribas of France as they have some of the largest operations in Turkey among euro zone banks.

Turkish President Recep Tayyip Erdoğan struck a defiant note in a series of Twitter messages shortly before Trump's announcement.
The lira, which has lost more than 40 percent this year, hit a new record low after Trump took steps to punish Ankara in a wide-ranging dispute.
Turkish President Recep Tayyip Erdogan says his country is at war and will not lose.
