5.26%! Japan's Largest Wage Increase in 35 Years Arrives, Central Bank Rate Hike Window May Open Early

Japanese companies are preparing for their largest wage increases in 35 years, supporting further rate hikes by the Bank of Japan. However, energy price shocks triggered by Middle East conflicts are disrupting this outlook.

On March 23, The Wall Street Journal reported that Japan’s largest labor organization, Rengo, released preliminary data showing that its 1,100 member organizations achieved an average wage increase of 5.26% this year, slightly higher than last year’s 5.25%. Major companies like Toyota, Honda, and Hitachi fully met the union’s wage demands.

This result has heightened expectations for the Bank of Japan’s rate hikes. The overnight index swap market indicates that investors see about a 60% chance of a rate hike as early as April; S&P Global Market Intelligence economist Harumi Taguchi expects the BOJ to raise rates to 1% by July. However, ongoing Middle East conflicts and rising energy prices threaten corporate profit margins and could suppress consumer demand, challenging the positive cycle of wages and inflation.

Wage increases hit highest level since 1991

Rengo’s data shows that this spring’s wage negotiations (shunto) in Japan resulted in an average increase of 5.26%, the highest since 1991. Rengo President Tomoko Yabuno said this reflects a shared understanding between labor and management of the importance of “investing in people,” which is believed to help promote sustainable corporate growth and improve Japan’s overall productivity.

Major companies like Toyota, Honda, and Hitachi fully accepted union wage demands, demonstrating strong willingness among large firms to raise wages. Bank of Japan Governor Kazuo Ueda stated that the wage increase trend is extending to small and medium-sized enterprises. The BOJ’s regional branch managers’ meeting in early April is expected to provide more insights into wage trends.

Middle East conflicts impact Japanese industry: Naphtha shortages, auto exports under pressure

Despite positive wage data, the impact of Middle East tensions on Japan’s economy is becoming evident. Marcel Thillien, head of Asia-Pacific at Capital Economics, pointed out that about 70% of Japan’s naphtha (a key raw material for plastics) comes from the Middle East, with current inventories lasting only about 20 days; half of the refineries relying on naphtha for plastic production have already cut output.

Exports are also under pressure. Middle East accounts for 15% of Japan’s auto exports, and manufacturers face delivery difficulties to the region. Additionally, Moody’s economist Stefan Angrick warned that factors like U.S. tariffs and increased external competition pose additional risks.

BOJ maintains cautious stance, watching the situation unfold

The Bank of Japan kept its policy rate at 0.75% at last week’s monetary policy meeting, citing the need for more time to assess the impact of geopolitical conflicts on the economy, but also emphasizing that the domestic economic fundamentals remain solid before risks escalate, and it remains committed to seeking further rate hikes.

The Middle East conflict presents a dual challenge for the BOJ. If commodity price shocks lead to cost-push inflation, consumer demand could weaken; if corporate profit margins are squeezed, their willingness to raise wages may diminish, undermining the positive wage-price cycle the BOJ aims to build.

S&P Global Market Intelligence economist Harumi Taguchi said: “If this trend continues among small and medium-sized enterprises and the Middle East situation stabilizes, it will be seen as evidence that the cycle of cost pass-through and wage increases can be maintained.”
