The euro jumped when the Eurogroup leader said there was reason for some optimism on Greek deal

Of course, the words of his predecessor should be kept in mind.

Juncker was also in the press today: "I see Greece as a permanent member of the euro family," he said. "A Greek exit won't happen."

Overall, Dijsselbloem's comments probably aren't as optimistic as the market is making them out to be: Talks are "quite complicated" he said. "There is still reason for some optimism but it's very difficult"
