From deflation to a new inflation equilibrium
Several positive developments are worth highlighting. In particular, the country appears to be in a new inflation equilibrium. In a very low or even negative inflation environment – which Japan experienced for 25 years from the mid‑to‑late 1990s – there are limited opportunities for wage increases, and this feeds through to weak consumption. That dynamic can then lead to a self‑reinforcing spiral in which a lack of demand is associated with reduced pricing power and the cycle begins again.
One of the few positive things emanating from Russia’s invasion of Ukraine is that the higher energy prices that followed appear to have kick‑started more durable positive inflation dynamics in Japan. These inflationary forces have subsequently been augmented by strong AI‑related demand and a weaker exchange rate.
The headline Japanese consumer price index (CPI) increased at an annual average rate of just 0.2% in the 30 years to end March 2022, during which time the country experienced deflation (negative inflation) in more than 40% of the months. Since then, Japanese consumer prices have increased by an average of 2.8%.
Core inflation – excluding fresh food and energy – has followed a similar pattern to the headline data. While too much inflation can be dangerous, a little bit of inflation is not necessarily a bad thing. It can facilitate adjustments to the real economy that would otherwise be more painful, and it also mitigates against the possibility that inflation is overestimated. It is for reasons such as these that central banks have positive inflation targets.
Wages finally responding: income growth and domestic demand
However, positive consumer price inflation that is not matched by wage inflation of at least the same order of magnitude is not good for an economy because it reduces individuals’ purchasing power. Another positive for Japan is that there are growing wage pressures, evidenced by the fact wages have grown faster than consumer prices in every month this year. Disaggregating this, there are some parts of the economy for which wage inflation is significantly above price inflation. So far this year, wage growth has averaged 3.5% compared to average headline inflation of just 1.6%. Furthermore, it is encouraging that wage growth appears to be most rapid for younger workers who tend to consume a higher proportion of their income than for older employees, who want to save for their retirements (Figure 22).
