Where Did the Fed's 2% Inflation Target Come From?
Since formally announcing it in 2012, the Federal Reserve has maintained a long-run inflation target of 2%.
That raises an obvious question: why 2%, rather than zero inflation or 3%?
The number did not emerge from a precise mathematical formula. To understand why the Fed rejected zero inflation and deliberately steered away from 3%, we need to trace the reasoning behind it.
Why not zero?
Zero inflation may sound ideal, but it creates several problems.
First, price statistics are subject to measurement error. If the reported rate is exactly zero, the economy may already be experiencing deflation. Second, persistently low inflation usually means lower nominal interest rates. When a recession hits and short-term rates reach their lower bound, monetary policy has less room to respond.
Wages also matter. At a 1996 FOMC meeting, Janet Yellen noted that people are generally reluctant to accept cuts in nominal wages. Moderate inflation can help firms make adjustments through changes in relative wages.
Why not 3%?
In the 1996 discussions, committee members worried that very low inflation would make economic adjustment more costly. At the same time, they did not want inflation, which had already been brought down, to return to around 3%.
Around 3% was therefore more a boundary they did not want to cross again. A 2% target gradually emerged as a compromise among low inflation, room for monetary policy, and wage adjustment.
Interestingly, even the question of whether that 2% should be measured using the CPI or PCE had not been fully settled at the time. Two percent is not a naturally occurring scientific constant.
How often has inflation actually hit 2%?
From 2012 through August 2026, there were 176 months. Using the revised headline PCE data, inflation was above 2% in 78 months and below it in 98. It was never exactly 2% in any month.
The lowest reading was just 0.04% in January 2015. A sharp fall in global oil prices at the time meant declining energy prices pulled headline inflation down substantially.
The highest was about 7.22% in June 2022. The recovery in demand after the pandemic, supply-chain disruptions, and the energy, food, and commodity shocks associated with the Russia–Ukraine conflict together pushed inflation higher.
The Fed also experienced 57 consecutive months of inflation below 2%, followed by 66 consecutive months above it.
Why keep holding to 2%?
The long-run target has remained at 2%. What has changed is how the Fed treats deviations from it.
In 2020, it adopted an average inflation target of 2%, allowing temporary overshoots to make up for earlier periods of below-target inflation. It dropped that makeup approach in 2025, while keeping the 2% target itself.
Two percent is therefore neither a hard requirement that must be met every month nor a monthly performance benchmark. It is an anchor: its purpose is to keep long-term inflation expectations stable and prevent judgments about the long-run path of prices from drifting too far off course.
