Line chart shows actual monthly year-over-year percentage changes in U.S. core CPI from January 1995 through May 2021. It also shows projected monthly year-over-year percentage changes under two scenarios from June 2021 through December 2022. The first scenario is Vanguard’s baseline forecast for U.S. core CPI, and the second is Vanguard’s “go big” upside forecast for U.S. core CPI. A horizontal band shows the legacy inflation target range of 1.75% to 2.25% that the Federal Reserve abandoned in August 2020 in favor of a policy of average inflation targeting, which allows inflation to surpass that level for some time. The chart shows that actual U.S. core CPI spiked to almost 3% in April 2021. The projection of Vanguard’s baseline forecast scenario shows U.S. core CPI exceeding 3% at times in 2021 but falling below that in 2022. The projection of Vanguard’s “go big” upside forecast scenario shows U.S. core CPI remaining consistently above 3% in 2021 before moderating in 2022.
