Headline inflation slowed in November for the first time in 1-1/2 years, to 10%, raising hopes that sky-high price growth has passed.
ECB President Christine Lagarde will likely be careful about calling a peak after last year's "big mistake" of insisting surging prices were "transitory," said Pictet's Ducrozet.
ECB Chief Economist Philip Lane reckons wages would be a "primary driver" of price inflation even after energy price shocks fade.
Closely-watched business activity data points to a mild recession and latest forecasts should show how the ECB views the coming slowdown.
Lane believes record price growth will start to subside next year.
