(Sharecast News) - European stocks had extended gains by midday on Thursday as investors eyed the latest policy announcement form the European Central Bank.

The benchmark Stoxx 600 index was up 0.5% at 647.38, Germany's DAX was 0.9% firmer at 25,931.97 and France's CAC 40 was up 0.9% at 7,955.89.

The ECB is widely expected to leave rates unchanged at 2.50% when it announces its rate decision at 1315 GMT. Just hours ahead of the announcement, the ECB said that president Christine Lagarde plans to step down on 7 February 2027, before the end of her term. Lagarde had been due to step down next October.

Holger Schmieding, chief economist at Berenberg, said: "That she leaves early is no surprise and does not change the outlook for ECB policies and for the way the ECB deals with French risks, in our view. Only the timing of her announcement has come as a modest surprise."

Overnight, the Fed left policy rates unchanged at between 3.75% and 4.00%, as expected, with Hammack and Cook dissenting and favouring a 25 basis points hike.
