The morning after the Nikkei fell 3,318 yen: Is the US stock rebound a sign of relief? Semiconductors and oil remain a burden despite falling interest rates

Key Takeaway

US stocks showed a rebound, and Nikkei futures exceeded the most recent spot price.

However, the NASDAQ 100 and semiconductor stocks fell, and WTI is at $97.60. The PPI was also strong, meaning the inflation problem has not been solved.

Rather than the magnitude of the rebound, I will check whether anxiety over earnings is fading and if the recovery is broadening.

Do not treat the sharp drop in Japanese stocks and the rebound in the US as events occurring at the same time

On October 15, the Nikkei Stock Average was 64,425.95 yen, down 3,318.34 yen from the previous day, a 4.90% decline. In the subsequent US market, the S&P 500 and the Dow rebounded.

What is important is that information and prices continue to move even after cash trading in Tokyo has ended.

We cannot treat the US rebound as information that the Tokyo market knew about the previous day.

This morning’s Nikkei futures are up about 1,374 yen compared to the cash market. On the other hand, this is not a level that recovers everything lost in the 3,318-yen drop the previous day.

Distinguish between expectations for a rebound and returning to the state before the decline.

In today’s cash market, we will check not only the high opening but also whether the rise continues afterward.

A rebound that merely corrects trading imbalances and a rebound where corporate valuations improve have different sustainability, even if they look similar.

US stocks did not recover across the board either.

The S&P 500 was up 0.33% and the Dow was up 1.08%. However, the NASDAQ 100 was down 0.05% and the SOX was down 0.88%.

This is not a picture where the previous day’s sharp drop has been completely resolved.

At the very least, from the data, we cannot read that growth stocks or semiconductor stocks are leading the recovery.

From here on is the analysis.

Even if stock valuations are supported by falling interest rates, buying may not spread easily in sectors where concerns about sales, profits, and investment recovery remain.

Therefore, do not generalize that ‘US stocks are up, so Japanese stocks are safe,’ but instead check which market movements the stocks you are watching are related to.

Even among semiconductor companies, customers, products, order backlogs, and capital investment plans differ.

It is necessary to look at whether profits and cash flow are being maintained in earnings reports, rather than judging solely by industry name.

The PPI was strong—this is not a rebound where price vigilance has disappeared.

The September PPI released by the US Bureau of Labor Statistics on the 15th showed that final demand rose 1.3% month-on-month and 6.3% year-on-year.

The index excluding food, energy, and trade services also rose 0.5% month-on-month.2026 M09 Results

Final demand goods rose 2.6% month-on-month, and over 80% of that increase was due to energy.

Meanwhile, services also rose 0.8% month-on-month.2026 M09 Results

The PPI is an indicator that measures changes in the prices received by producers.

It serves as material for considering corporate cost burdens, but it is not the same as the purchase prices of all companies or the subsequent CPI.

Because price pass-through, contract periods, inventory, and procurement sources differ by company, the impact on profits also varies.

One should not mechanically read it as ‘the consumer price index for the following month will rise by the same amount that the PPI rose’.

Even so, it is difficult to say from these figures that inflationary pressure has subsided.

The image display of crude oil at 97.60 dollars is also a reason to continue monitoring energy burdens.

Why do interest rates and the dollar fall even with strong price indicators?

Usually, the strength of prices leads to caution regarding monetary tightening.

However, this morning the US 10-year Treasury yield fell to 5.085%, and the dollar-yen also fell to 158.078 yen.

Reuters reported on the 15th that in addition to cautious remarks by Fed officials easing expectations for further rate hikes, concerns over the debt burden of AI-related companies prompted capital inflows into US Treasuries.Reuters

In other words, the decline in interest rates may be related to both ‘expectations for policy’ and ‘demand for safety’ at the same time.

One cannot summarize it into a single reason, such as bonds being bought because inflation has disappeared.

This distinction is important when looking at stocks.

If prices stabilize and profits are maintained, falling interest rates can be a tailwind.

On the other hand, if the reason is anxiety over investment recovery or cash flow, falling interest rates alone do not necessarily mean growth stocks will recover.

Rather than the direction of interest rates, I will confirm whether their decline is compatible with peace of mind regarding corporate profits.

Retail sales up 0.8%—can we definitively say households are strong?

According to the US Census Bureau, the preliminary report for retail and food service sales in September increased by 0.8% month-on-month and 6.3% year-on-year.

However, this statistic does not adjust for price fluctuations.Sales Report

There are two paths through which sales amounts increase: an increase in the quantity purchased, and an increase in price for the same quantity.

The total amount alone cannot determine which factor had how much of an impact.

For example, even with the same amount of fuel, if fuel prices rise, the payment at the gas station increases.

It is possible that other purchases are being reduced to compensate for that.

Therefore, we do not judge that ‘households have disposable income’ based solely on an increase in retail sales.

We layer in the breakdown by industry, prices, corporate sales volumes, and customer trends.

The stock market evaluating the resilience of consumption and the actual living conditions of households are two different things.

This discrepancy is a point we want to confirm in future earnings reports as well.

High crude oil prices and the movement toward a stronger yen—which burden will prevail for Japan?

Even if crude oil is expensive, if the yen strengthens, part of the import burden may be eased.

However, the decline rate of the dollar-yen this morning is small, and we cannot judge that the burden of crude oil has been resolved by that alone.

The simple yen-denominated price is the product of dollar-denominated crude oil and the dollar-yen exchange rate.

Actual payments involve long-term contracts, foreign exchange hedging, and the timing of inventory acquisition.

Even if interest rates move first in the financial markets, electricity bills and logistics costs on the ground may be reflected with a delay.

There is a time lag between market rebounds and improvements in cost prices.

If crude oil prices remain high even if stock prices recover in the future, companies will need to continue reviewing their profit margins.

We will consider market relief and the updating of cost budgets separately.

Three future scenarios and judgment criteria

The following are the monitoring criteria set in this article, and are not definitive predictions or established market turning points.

For the US 10-year Treasury and WTI, we use standard market values and confirm the closing price and the following day’s continuity rather than temporary fluctuations.

1. Main: While rebounding, the differences between individual companies will widen

This is the case if the 10-year US Treasury yield remains around 5.00–5.20%, WTI remains around $95–$100, and corporate earnings forecasts do not collapse significantly.

In this scenario, even if falling interest rates support some stock prices, we anticipate a trend of continued selection based on energy costs and investment recovery differences.

We will watch to see if the rebound in Japanese stocks lasts beyond the opening and if the recovery spreads to US semiconductor stocks as well.

② Upside: Rebound spreads to growth stocks, and crude oil prices stabilize

This is the case if WTI returns to below $95 and the NASDAQ 100 and SOX recover over several days.

If interest rates stabilize and demand and profit margins are maintained in earnings reports, it will be easier to evaluate the sustainability of the recovery.

The confirmation condition is that not only do interest rates fall, but ‘broadening stock price gains’ and ‘reduced cost burdens’ overlap.

We will not move to this assessment based solely on an overnight rise in futures.

③ Downside: High crude oil prices persist, and anxiety over growth stocks reignites

This is the case if WTI settles above $100, semiconductor stocks fall sharply again, and corporate outlooks deteriorate.

If the 10-year US Treasury yield returns to above 5.20%, we will be wary of both inflation and financing.

Even if interest rates fall below 5%, if stock prices continue to fall and earnings forecasts worsen, we will confirm this as an intensification of growth anxiety.

We do not treat falling interest rates as good news in every case.

Impact on individuals—What to check on a rebound day

Seeing futures rise after a sharp drop makes one want to feel relieved.

However, there is no need to change the decision to separate living expenses from long-term investment funds based on an overnight rebound.

Even if you hold multiple index products, they may all depend on the same large-cap growth stocks.

Rather than the number of products, check which companies and revenue structures your funds are placed in.

For bonds as well, look at price increases due to falling interest rates and currency fluctuations in yen terms separately.

The fluctuations you should evaluate change depending on whether the money is needed before maturity or if it is money you can continue to hold.

For households, do not link increases in retail sales to your own disposable income; instead, check actual expenditures on utilities, food, and transportation.

Even if the inflation rate slows, it does not necessarily mean that payment amounts will return to their original levels.

Impact on companies—even if there is a rebound, continue to monitor costs and funds.

When the market recovers, there is a temptation to end precautionary measures.

However, if crude oil prices remain high and the PPI remains strong, there is a reason to continue monitoring costs and funds.

Sales should check sales volume and price pass-through, procurement should check material and logistics costs, and finance should check exchange rates and payment terms.

Even if sales figures are increasing, look to see if a decrease in volume or a decline in profit margins is hidden.

For example, decide that “if WTI stays above $100 for several business days, procurement and finance will organize the impact on costs and funds, and sales will confirm the room for price pass-through.”

Clarify who will integrate that information and when it will be passed to the approver.

While increasing inventory can be a preparation for supply instability, it also ties up capital.

Evaluate inventory days, alternative procurement periods, and payment terms together.

Do not end measures just because stock prices have recovered; change your response only after confirming that your company’s burden has eased.

That order is important in practical business.

Five judgment factors to check next

• US import/export prices at 21:30 today, the 16th: Import price pressure. bls.gov

• Statements by Fed officials: Whether they place more weight on prices or growth.

• Corporate earnings: Profit margins, capital investment, and operating cash flow.

• NASDAQ 100 and SOX: Whether the rebound will spread to growth sectors.

• WTI and USD/JPY: Whether Japan’s yen-denominated burden will ease.

Since schedules are subject to change, reconfirm with official information on the day.

Conclusion

This morning’s rebound in U.S. stocks and the rise in Nikkei futures indicate that buying has returned following the sharp decline.

However, the weakness in the NASDAQ 100 and semiconductor stocks, oil at $97.60, and strong PPI remain.

Rather than the magnitude of the rebound, the question is whether the recovery will broaden and whether lower interest rates will lead to improvements in profits and costs.

Only after confirming these points can we say that the factors for relief have increased.

Which of these would you like to confirm?

1. Continued rebound in Japanese stocks 2. Recovery in semiconductor stocks 3. Oil and cost of living
