The eurozone’s deflationary trap just caught the big fish. Inflation in Deutschland, Europe’s economic engine, fell below zero for the first time since 2009. The 0.5 percent decline in consumer prices over the last 12 months was almost entirely due to collapsing oil prices. Germany’s predicament means the eurozone faces an even bigger risk of falling prices and stalling economic activity than previously thought, especially in its weaker markets. Maybe now the Germans won’t view the European Central Bank’s stimulus bazooka with such disdain.
