Japan's economic activity slowed in May, but it's important to note that it remains in growth territory.
The final S&P Global Composite PMI for May was 51.1. Any reading above 50 signifies economic expansion, so this is still a positive signal. However, the figure has dropped from 52.2 in April, marking a five-month low and suggesting a loss of momentum. This slowdown reveals a 'two-speed' economy: the manufacturing sector is performing strongly with a PMI of 54.5, buoyed by robust exports, while the services sector has stalled right at the 50.0 mark, which separates growth from contraction.
So, what caused this divergence? Several factors are at play, creating a clear causal chain.
First, the most immediate influences from May set the stage. Low consumer inflation in Tokyo, at just 1.3%, weakened the pricing power of service-based businesses. In contrast, solid industrial production figures and a strong 14.8% year-over-year increase in April's exports provided a significant tailwind for manufacturers. The weaker yen also played a part, making Japanese goods more competitive abroad and further supporting the factory sector.
Second, looking back to April provides more context. The Bank of Japan (BOJ) held its interest rate at 0.75% but signaled a 'hawkish' readiness to hike if necessary. This created a cautious atmosphere, especially for domestically-focused service companies. Furthermore, slowing nationwide inflation also limited the ability of these firms to pass on rising costs to consumers.
Third, longer-term trends have also shaped this outcome. The substantial wage increases from the annual 'Shuntō' spring labor negotiations have raised costs, squeezing margins in the labor-intensive service sector. Additionally, the BOJ's rate hike in December 2025 began a gradual policy normalization process, which, over time, tends to cool domestic demand more than the export-driven manufacturing industry.
In essence, the May PMI data paints a picture of a resilient manufacturing sector keeping the economy expanding, while the domestic services side is taking a pause. This mixed economic signal gives the Bank of Japan more reason to remain patient before considering another rate hike.
