Inflation Targeting

Inflation targeting (IT) is a monetary policy strategy in which the central bank announces an explicit target—typically a point figure or narrow band for annual consumer price inflation—and uses its policy instruments, primarily a short-term interest rate, to steer actual inflation toward that target over a medium-term horizon. The framework rests on three pillars: a quantified objective, central bank instrument independence, and transparent communication (inflation reports, published forecasts, press conferences).

Origins. New Zealand became the first country to formally adopt inflation targeting in 1990, following the Reserve Bank of New Zealand Act 1989, which established a Policy Targets Agreement between the Minister of Finance and the Governor. Canada followed in 1991, the United Kingdom in 1992 after exiting the Exchange Rate Mechanism, and Sweden in 1993. Emerging markets including Brazil, Chile, South Africa, and Poland adopted variants in the late 1990s and early 2000s.

Typical features.

• A target often set at 2% (used by the European Central Bank, Bank of England, Federal Reserve, and Bank of Japan) or a band such as 3% ±1% in many emerging economies.
• A medium-term horizon, recognizing that monetary policy affects prices with lags.
• "Flexible" inflation targeting, in which the central bank also weighs output and employment stability, as articulated by economists Lars Svensson and Ben Bernanke.

Debates. Proponents argue IT has anchored inflation expectations and improved policy credibility. Critics note it can underweight financial stability risks—an argument that gained traction after the 2008 global financial crisis—and can be difficult to operate at the effective lower bound on interest rates. In August 2020 the U.S. Federal Reserve shifted to "flexible average inflation targeting," allowing inflation to run moderately above 2% after periods below it. The post-2021 global inflation surge renewed debate over target levels, with some economists proposing a higher target, while most central banks have retained the 2% benchmark.
