This new publication “inflation tracker” aims to provide an easy-to-read monthly overview of inflation dynamics in the main developed economies. The chartbook includes current price dynamics (consumer and producer prices, and their main contributors), those anticipated by households and businesses, as well as breakeven rates induced from financial markets. The relationship between inflation and some of its main determinants is also included. This first edition of the inflation tracker covers the United States, the Eurozone and the United Kingdom. This document will be expanded over time.
