The 2% inflation target is key to the Federal Reserve's vision for stable prices in the U.S. economy, according to the Federal Reserve Bank of St. Louis.
But, "the 2% inflation target, it's relatively arbitrary," Josh Bivens, director of research at the Economic Policy Institute, told CNBC.
"We led the way in inflation targeting," Arthur Grimes, professor of wellbeing and public policy at Victoria University, told CNBC.
Canada announced its inflation target in 1991, and the United Kingdom followed suit in 1992.
Then, Sweden and Finland declared inflation targets in 1993, according to the Organization for Economic Cooperation and Development.
