Japanese manufacturing hits fastest pace in over a decade but risks loom

War in Middle East triggers frantic stockpiling as supply lines suffer worst delays since 2011 tsunami.

Japanese manufacturers are churning out goods at their fastest rate in over a decade, but experts warn the boom rests on a knife-edge as Middle Eastern conflict wreaks havoc on global trade.

The latest S&P Global Manufacturing PMI data reveals that factory output in April surged at its quickest pace since February 2014. The headline index jumped to 55.1 from March’s 51.6, marking the sector’s strongest performance in over two years.

However, beneath the surface of this production sprint, businesses are grappling with a "stark" reality. The same conflict driving a rush of new orders is also strangling supply chains, with delivery delays hitting levels not seen since the devastating Tohoku earthquake and tsunami in 2011.

Panic buying and AI demand

Whilst genuine demand for AI-related technology is providing a legitimate tailwind, much of the current activity stems from anxiety. Fearful of future shortages and price hikes, manufacturers and their clients are aggressively stockpiling goods. This rush for inventory helped drive new business growth to its highest level since early 2022.

Costs on the march

The logistical nightmare is proving expensive. Manufacturers reported the steepest rise in input costs for three-and-a-half years, fuelled by soaring prices for raw materials, oil, and freight. To protect their margins, firms are passing these costs on to consumers, raising their own selling prices at the fastest rate seen since late 2022.

A fading fuse?

Despite the hiring of new staff at a near-record pace to tackle mounting backlogs, the mood in Japanese boardrooms is darkening. 

Business optimism has plummeted to its second-lowest level since the early days of the 2020 pandemic.

Annabel Fiddes, Economics Associate Director at S&P Global Market Intelligence, warned that the current "rebound" might be a flash in the pan.

"The strain on supply chains is stark," she said. "This suggests the current boost to manufacturing could soon fade unless we see reduced market uncertainty and more stable supply chain conditions."

Without a cooling of geopolitical tensions, Japan’s manufacturing engine risks overheating just as the global economy enters increasingly choppy waters.
