The European Central Bank (ECB) released its Financial Stability Review on Thursday. The central bank said that if debt talks between Greece and its creditors last for a long time, it could raise the yields on debt of other countries from the Eurozone.

"Financial market reactions to the developments in Greece have been muted to date, but in the absence of a quick agreement on structural implementation needs, the risk of an upward adjustment of the risk premia demanded on vulnerable euro area sovereigns could materialize," the ECB said.
