BERLIN (Reuters) -German inflation eased slightly more than expected in March, helped by a drop in energy prices, preliminary data from the federal statistics office showed on Tuesday. German consumer prices, harmonised to compare with other European Union countries, had risen by 2.7% year-on-year in February. Looking ahead, headline inflation in Germany could drop to 2% as soon as next month, before rebounding somewhat in the months after, according to Brzeski.
