On August 31, Japan's Ministry of Economy, Trade and Industry announced that the seasonally adjusted industrial production index for July was 104.7, with a month-on-month increase of only 0.1%. Shipments increased by 2.2%, inventory rose by 0.5%, and the inventory ratio decreased by 1.7%. Compared to the same period last year, unadjusted production increased by 4.1%. Taken together, these figures do not depict a clear upward trend; rather, they indicate that production has barely increased, shipments have improved significantly, and the inventory structure is still in the process of adjustment. As a result, the Ministry has maintained its assessment that "the trend of industrial production is unclear."
For the market, 0.1% can easily be categorized as stagnation, but the detailed figures contain more information than the headline figure. Production of machinery, inorganic and organic chemicals, electronic components, and equipment drove output; however, transportation equipment (excluding automobiles), metal products, and plastic products were a drag. The inconsistent direction within the industries indicates that the recovery in demand still relies on a few sectors, and it is difficult to infer from one month's data that the manufacturing sector has entered a phase of stable expansion.
Production remains almost unchanged, yet shipments and inventory levels provide conflicting signals.
The shipment index rose to 103.5, a month-on-month increase of 2.2%, mainly driven by transportation equipment not including automobiles, petroleum and coal products, as well as production machinery. The faster growth rate of shipments compared to production usually indicates that companies are fulfilling existing orders or working through inventory, which is a positive sign for short-term operations. However, the delivery of transportation equipment in a single month may be affected by large-scale projects and export timing, and petroleum product shipments can also be subject to seasonal and price variations, so their sustainability still needs to be observed.
The inventory index is 98.1, showing a month-on-month increase of 0.5%, but the inventory ratio has decreased by 1.7%. An increase in inventory itself does not necessarily mean overstocking; the simultaneous decline in the inventory ratio indicates that the inventory pressure has been alleviated relative to shipments. In specific industries, there has been an increase in inventory for electrical machinery and information and communication electronic equipment, as well as manufacturing machinery; however, inventory for electronic components, steel, and non-ferrous metals has decreased. Enterprises are stocking up for anticipated orders while clearing old inventory, indicating that the manufacturing sector is not in a unified state.
Year-on-year data looks more favorable: production increased by 4.1%, shipments increased by 4.8%, and inventory decreased by 2.0%. However, due to the base effect from the same period last year, year-on-year figures cannot replace the month-on-month trend. In July, the month-on-month increase was only 0.1%, indicating that even after recovering to a relatively high level, new momentum is still weak. For Japan's manufacturing industry, which relies on exports, overseas demand, exchange rates, energy costs, and supply chain arrangements can all cause significant fluctuations in monthly figures.
This report uses an index scale with an average value of 100 for the year 2020. A value of 104.7 indicates that the level of output is higher than the average of the base period, which does not mean that economic growth was 104.7%. The index measures changes in quantity and does not directly reflect corporate profits; even if factories produce more, rising costs of raw materials and labor could compress profits. When analyzing industrial production, it is necessary to combine this with data on orders, exports, corporate surveys, and prices.
Expected to increase significantly by 6.4% in August, followed by a decline of 4.2% in September, revealing fluctuations in the plan.
Manufacturing production forecast surveys show that companies expect a 6.4% month-on-month increase in production in August, followed by a 4.2% decline in September. The growth in August mainly came from production machinery, electrical machinery, information and communication electronic equipment, and transportation equipment; the decline in September was also concentrated in production machinery, transportation equipment, and electronic components. This pattern of initial surge followed by a significant drop may reflect the scheduling of large orders, factory maintenance timing, and differences between working days, rather than a sudden full boom and contraction in demand.
The survey forecasts plans of enterprises, not the actual production that has already been completed. Enterprises will adjust their schedules based on orders and inventory, and the actual results may also be affected by the supply of parts, weather, exchange rates, and changes in external demand. The value of the planned figures announced by the Ministry of Economy, Trade and Industry lies in revealing the current expectations of enterprises; it should not be interpreted as meaning that production in August has increased by 6.4%. Especially when the trends in two consecutive months are opposite, it is more important to focus on the combined level of the two months rather than focusing solely on a single percentage increase.
The key to the next phase of Japan's manufacturing industry is whether improved shipments can drive broader production. If the 2.2% increase in shipments in July comes from actual orders rather than changes in delivery times, companies may continue to increase production after inventory levels drop; however, if it is merely a concentrated delivery, there could still be a rapid cooling down after the planned rebound in August. The reduction in electronic component inventory is a noteworthy clue, but it could either indicate strong demand or represent companies being cautious about reducing production.
In terms of macro policies, industrial production only covers a part of the economy; Japan's service sector and household consumption are equally important. Weak manufacturing data does not necessarily indicate an overall economic contraction, and a single-month rebound does not mean that wages and household demand have improved simultaneously. Central banks and governments are more concerned with whether a sustainable cycle can be formed between output, prices, and wages.
The core of the July report is not whether 0.1% is good or bad, but rather that multiple trends exist simultaneously: production is nearly stagnant, shipments are growing rapidly, inventory has increased slightly but the inventory ratio has decreased, and corporate plans indicate significant fluctuations in August and September. It is reasonable for the Economic Production Ministry to describe this situation as "unclear trends." A real turning point requires confirmation from data over several consecutive months, especially to see how much of the plans for August can be fulfilled, and whether the decline in September is merely a result of scheduling adjustments.
It should also be noted that the initial values will be revised once more corporate data becomes available. For both companies and investors, a more cautious approach is to track the three-month moving trend and to verify the number of days of inventory against export orders, in order to avoid mistaking changes in a month's factory scheduling for a cycle in the entire manufacturing industry.
