The euro is diving after Italy's prime minister resigned
Matteo Renzi announced his resignation on Sunday evening after losing a referendum on constitutional changes that he had staked his career on.
Renzi said in his resignation speech: "Italy has chosen. Now it's up to those who won to make proposals."
While Renzi's loss and resignation is not a shock - it had looked like he was heading for defeat in the run-up to the vote - it means more instability and uncertainty for Europe.
The euro is suffering as a result. It is down almost 1% against the dollar at close to 7.00 a.m. GMT (2.00 a.m. ET):
"Could there be a Trump moment for markets? And after an initial sell-off, selling pressure could start to ease."
However, the euro's performance will most likely be determined by the performance of Italian banking stocks once stock markets open. Senior banking officials were worried ahead of the vote that a "No" vote could lead to the failure of as many as eight Italian banks.
