An ECB source reportedly told Econostream that some ECB policymakers, for example Austria's Robert Holzmann, will push for a 50 bps rate hike, though any such move is not a foregone conclusion. A 50 bps Deposit Facility Rate hike and a 25 bps hike in the Refinancing Rate would narrow the corridor in one move, the source said, before conceding that the ECB would first want to prime markets for any such move. 

Earlier in the day, ECB President Christine Lagarde said that the ECB will maintain optionality in current conditions of high uncertainty.
