The ECB’s Praet spoke in an interview with the Financial Times.

“Following the last governing council, we have tasked the different committees of the central bank to work on potential additional measures, if needed. And basically you have two committees, there’s the market operations committee and the Monetary Policy Committee. So the two committees will work on contingencies, additional measures if needed . . . these committees have a very open mandate, and there is really no taboo in terms of what they should study.”

That’s not an agreement that those measures are necessarily legal so I don’t take much from it.
