ECB working on the assumption that Greece won't leave euro: Constancio

Speaking to reporters after the ECB published its latest financial stability report, Constancio added that Greek banks were still viewed as "solvent" and that there was no automatic connection between a Greek government default on its bailout loans and banks becoming insolvent.

We are "working on the assumption that Grexit won't happen," Constancio said.
