"The Draghi speech was in the end quite accommodating," Alexandre Baradez of Saxo Bak in Paris.
"The ECB sees signs of recovery while remaining vigilant," he said.
France has triggered a debate this week that a strong euro could trample tender green shoots of recovery in the eurozone, even as Germany insists there is no cause for alarm just yet.
