Lagarde is scheduled to speak at 0830 GMT today
Eamonn also gave a bit of an earlier heads up here.
She will be delivering opening remarks (for ~5 minutes) at the ECB colloquium held in honour of Benoit Coeure - who is leaving the central bank at the end of the month. Notably, after she is finished, there will be an address by her predecessor Mario Draghi.
The full agenda can be found here.
Given the backdrop of the event, I doubt we will get any heavy remarks on policy or the upcoming strategy review so I wouldn't expect we'll hear much - if anything at all.
