Inflation Targeting [IT]

Inflation targeting is a monetary policy strategy where central banks publicly announce and commit to achieving a specific inflation rate, typically around 2% annually. New Zealand pioneered this approach in 1990, followed by Canada, UK, and eventually most developed economies. The framework involves setting a clear numerical target, regular communication about policy decisions, and accountability mechanisms. For example, the Fed formally adopted a 2% inflation target in 2012, measured by PCE (Personal Consumption Expenditures). Central banks adjust interest rates to keep inflation near target – raising rates when inflation exceeds target, cutting when below. Benefits include anchored expectations, transparency, and flexibility to respond to shocks. Challenges emerged during the 2010s when inflation remained below target despite ultra-low rates, and in 2021-2023 when inflation surged above targets globally. Some economists propose alternatives like nominal GDP targeting or asymmetric targets. The effectiveness depends on central bank credibility and communication strategies.
