In August, Japanese manufacturers were more positive, with the manufacturing index rising to +9 from +7 in July. This improvement marks the second consecutive month of increased optimism.
The transport machinery sector, notably auto manufacturing, showed the most robust growth, jumping to +25 from +9. However, it is expected to decline in the upcoming months. The non-manufacturing index decreased to +24 from +30, the first drop in five months.
Food Industry Decline
The food industry experienced a severe decline, falling to -25 from zero, due to rising ingredient and material costs. Sentiment in real estate, construction, and retail sectors also fell, partly because of decreased store traffic and extreme heat affecting services.
Looking ahead, the manufacturing index is predicted to decline to +4 by November. The non-manufacturing index is expected to be at +25 by the same time.
The survey, conducted from 30 July to 8 August, included responses from 241 out of 497 major non-financial firms. The monthly Reuters Tankan survey mirrors the Bank of Japan’s tankan quarterly survey by subtracting the percentage of pessimistic respondents from optimistic ones. Positive indexes indicate a greater number of optimistic responses.
Based on the August 12, 2025, data, we should approach Nikkei 225 derivatives with caution. The manufacturing index improved, but its three-month outlook is set to fall sharply to +4, suggesting the current strength is fragile. This indicates that now may be a good time to consider protective put options or hedge long-standing equity positions against a potential downturn this autumn.
Auto Sector Concerns
We see the surge in the auto sector as a potential trap for traders, as it is forecast to retreat. This reminds us of the supply chain whiplash effects we saw between 2022 and 2024, where production boosts were often temporary. Selling out-of-the-money call options on major auto stocks could be a strategy to capitalize on the view that this sector’s sentiment has peaked.
The decline in the non-manufacturing index, its first in five months, points to weakening domestic demand. The plunge in the food industry due to cost pressures aligns with national statistics, which have shown core inflation stubbornly hovering near 2.3% over the last year. This ongoing pressure on consumers and service firms could act as a drag on the broader economy.
For currency traders, this report reinforces the case for a weaker yen. The domestic softness gives the Bank of Japan little incentive to stray from the cautious monetary policy it has maintained since ending negative rates back in March 2024. This policy stance, when contrasted with the U.S. Federal Reserve’s higher interest rates, should continue to support long USD/JPY positions.
The conflicting signals between a rising manufacturing index and a falling non-manufacturing one create uncertainty. This divergence often leads to higher market volatility. Therefore, strategies like purchasing straddles on the Nikkei 225 index could be effective, as they profit from a large price move in either direction, regardless of which economic narrative wins out.
