Inflation targeting is a monetary policy framework in which a central bank publicly commits to a numerical objective for inflation and adjusts its instruments to bring inflation toward that objective over a specified horizon. It combines a measurable goal with forward-looking policy decisions, public communication, and accountability. Unlike a mechanical rule prescribing each policy action, it generally allows discretion over how quickly inflation should return to target after economic disturbances. (imf.org)
Origins and development
New Zealand became the first country to formally adopt modern inflation targeting in 1990. Its first Policy Targets Agreement, signed on March 2, 1990, specified reducing annual consumer-price inflation to between 0 and 2 percent by 1992. The arrangement linked a statutory price-stability mandate to an explicit agreement between the finance minister and the central bank governor. (rbnz.govt.nz)
Canada adopted inflation targets in 1991, initially setting a declining path toward lower inflation. The United Kingdom introduced targeting in 1992 and granted the Bank of England operational independence in 1997. Sveriges Riksbank announced Sweden’s target in 1993, with application beginning in 1995. The framework subsequently spread across advanced and emerging-market economies, although institutional arrangements and target definitions differ. (bankofcanada.ca)
Target design and measurement
A targeting regime specifies the price index, numerical objective, policy horizon, and conditions governing deviations. Targets may take the form of a point, a range, or a point accompanied by a tolerance band. The consumer price index is widely used, but national measures differ. Sweden, for example, targets the CPIF, a consumer-price measure that holds mortgage interest rates fixed, thereby excluding their direct mechanical effect on measured inflation. (imf.org)
Central banks may also examine core inflation measures to distinguish persistent pressures from temporary price movements, while retaining a broader index as their formal target. A tolerance or variation band does not necessarily mean that every outcome within it is equally desirable: Sweden’s 1–3 percent variation band illustrates normal fluctuations around its 2 percent point target rather than defining a target interval.

A low positive target provides protection against deflation and additional room to reduce nominal interest rates during downturns before encountering their effective lower bound. It can also facilitate relative wage adjustments when nominal wage cuts are difficult. These considerations explain why price stability need not mean zero measured inflation. (bankofcanada.ca)
Policy operation and transmission
Inflation targeting is forward-looking because policy changes affect prices with delays. Policymakers assess prospective inflation using forecasts and evidence concerning supply and demand, economic slack, wages, and other price pressures. Their decisions therefore depend on the expected inflation path rather than simply the latest published inflation rate. (bankofcanada.ca)
The principal instrument is commonly a short-term policy interest rate. Through the monetary transmission mechanism, changes in this rate and its expected future path influence borrowing costs, asset prices, credit conditions, and the exchange rate. Higher rates generally restrain expenditure and aggregate demand, reducing inflationary pressure over time. Their effects vary with economic conditions and financial structures; there is no fixed, universal relationship between a particular rate change and subsequent inflation. (bankofengland.co.uk)
The announced target also serves as a nominal anchor for inflation expectations. When credible, it supplies a common reference for wage bargaining and price-setting, helping prevent temporary inflation movements from becoming embedded in expectations of persistently different inflation.

Flexibility and institutional arrangements
Under flexible inflation targeting, policymakers consider output and employment when choosing the speed of adjustment. Returning inflation immediately to target could require large interest-rate changes and unnecessary economic instability. Flexibility concerns the adjustment path, however, rather than abandonment of the inflation objective: prolonged deviations can undermine confidence in the target. (riksbank.se)
Central bank independence, particularly authority to choose policy instruments, supports implementation. Other important foundations include a workable forecasting methodology, an understood transmission mechanism, a sufficiently developed financial system, and sound fiscal policy. Persistent pressure to finance public deficits through monetary expansion can conflict with the inflation objective. (imf.org)
Transparency connects operational discretion with accountability. Targets, forecasts, and explanations allow the public to assess decisions and departures from the objective. In the United Kingdom, government sets a 2 percent target, and the governor must write an explanatory letter when inflation differs from it by more than one percentage point in either direction. The letter explains the deviation and the intended response. (imf.org)
Performance and alternative frameworks
Assessing inflation targeting requires distinguishing improvements following adoption from improvements caused by adoption. Countries may introduce it alongside other reforms or after substantial disinflation. A 2023 IMF working paper found little average difference between targeting and non-targeting countries in inflation levels, volatility, or expectation anchoring, while finding limited support for claims that targeting systematically worsens economic growth. These findings caution against attributing national outcomes solely to the framework. (imf.org)
Conventional inflation targeting also differs from price-level targeting. Under the former, past departures generally do not require compensating future departures in the opposite direction. Under the latter, policy seeks to restore the price level to a specified path, requiring correction of accumulated misses. Consequently, returning inflation to target does not normally imply reversing earlier price increases. The distinction concerns the treatment of policy history, not merely the numerical inflation objective. (bankofcanada.ca)
