What did BOJ Governor Kazuo Ueda mean when he said 'oil price shocks are never just oil price shocks'?

Ueda meant that oil price shocks test the resilience of Japan’s entire inflation regime—not just headline energy prices—because they can trigger second-round effects such as wage increases, shifts in inflation expectations, and changes in corporate price-setting behavior; he emphasized that a temporary shock can become persistent if it alters these underlying dynamics, citing Japan’s history of five major oil shocks dating back to the 1970s.

Why does Ueda consider the current oil shock especially risky for Japan’s inflation outlook?

Ueda considers the current oil shock especially risky because it coincides with already-high inflation expectations and accelerating wages—conditions that increase the likelihood of second-round effects—and is further amplified by yen depreciation, which intensifies import price pressures; he specifically linked this dynamic to Russia’s invasion of Ukraine in 2022 and noted that the yen has since weakened significantly, trading at around 159.22 per dollar—far below its 2022 average of 131.55—thereby worsening the shock’s domestic impact.
