"We don't see substantial vulnerabilities. So, the probability of contagion is very small today. The banks are well capitalised," Greek central bank chief Stournaras said.

Stournaras added that Europe has all the instruments ready, if needed, to intervene.

Answering a question on how vulnerable some EU banks are to rising interest rates, he said: "I think the rate hikes are mostly now a story of the past."

"I think we are close to the end of the tightening cycle, so, to be honest, I do not believe that there is going to be a problem, in the Greek or in the European banking system."
