Historical Context

PPI turned negative YoY in 2009 (recession-driven), 2015-2016 (oil crash), and 2020 (COVID shock). The 2022-2023 cycle saw PPI peak at 11.7% YoY and decelerate to negative territory briefly in summer 2023 as energy prices collapsed. Prolonged PPI deflation in Japan (1990s-2010s) coincided with their extended economic stagnation. The 1980s saw PPI deflate during the Volcker-era disinflation, confirming broader inflation normalization.
