Euro area annual inflation is expected to be 7.5% in March 2022, up from 5.9% in February according to a flash estimate from Eurostat, the statistical office of the European Union.
Looking at the main components of euro area inflation, energy is expected to have the highest annual rate in March (44.7%, compared with 32.0% in February), followed by food, alcohol & tobacco (5.0%, compared with 4.2% in February), non-energy industrial goods (3.4%, compared with 3.1% in February) and services (2.7%, compared with 2.5% in February)
Energy prices will keep going through economy slowly driving everything else up; and there is no end in sight for energy crisis.
