Coeure: ECB doesn’t want extraordinary measures to become too permanent

WTH is "too permanent"?
– The balance of risks is balanced, by and large
– It’s important to note that the ECB monitors the Fed experience closely
– There’s not much discussion today about adding to the ECB balance sheet
He sounds like he’s trying not to tip himself into hawkish tones. "Too permanent"?? Something is either permanent or its not 😀
