The rise in crude oil prices is a major factor on October 8. Brent crude oil futures were up 4.13% as of 6:00 PM Japan time, raising concerns in Japan about the ripple effects on fuel and logistics costs. However, the rate of increase in crude oil does not directly translate into the same rate of price hikes for gasoline or consumer goods.
In the U.S., the minutes of the September FOMC meeting were released, and in Japan, the Bank of Japan’s regional economic assessment showed some improvement. This article breaks down crude oil, interest rates, and the yen exchange rate to consider how economic recovery and the burden of rising prices on households coexist.
Market data is based on values at the time of reporting from each source, and the next point to watch is the U.S. CPI on October 14. This information is provided for educational and economic commentary purposes and does not constitute individual investment advice.

1. Crude oil up 4.13%; supply concerns push up import costs

On October 8, as of 6:00 PM Japan time, Brent crude oil futures were up 4.13% at $102.28. In addition to shipping attacks in the Middle East, production cuts at U.S. offshore oil fields due to an approaching hurricane are intensifying concerns about supply.
Reuters crude oil report: https://www.marketscreener.com/news/oil-rises-as-middle-east-supply-concerns-persist-amid-shipping-attacks-ce785ddedf8af42d. Considering the impact on Japan, imported fuel and logistics costs are points to watch.
However, reflection in retail prices involves contracts, inventory, exchange rates, and subsidy systems. One should not conclude changes in living costs based solely on a temporary rise in crude oil; it is necessary to observe how long these high prices persist.
2. Views on additional U.S. rate hikes remain, but the timing is not yet fixed

In the September FOMC minutes released on October 7, most participants judged that an additional rate hike within the year would likely be appropriate. At the September meeting, the rate was raised by 0.25 percentage points, bringing the policy interest rate to 3.75–4.00%.
On the other hand, the minutes also specified a stance of making decisions based on new information at future meetings. FRB September minutes: https://www.federalreserve.gov/monetarypolicy/fomcminutes20260916.htm.
For the Japanese market, US interest rates are also a factor to consider regarding exchange rates and corporate financing environments. It is necessary not to confuse the minutes of this meeting with the new interest rate hike decision in October, but to compare them with subsequent price indicators.
3. 1 dollar at 158.16 yen, import prices change due to both crude oil and exchange rates

In the updated Reuters article on October 7, the dollar-yen was reported at 158.16 yen to the dollar, and the dollar rose slightly against the yen. This is the value at the time of reporting and is not the closing price for October 8.
Reuters exchange rate report: https://ca.investing.com/news/economy-news/dollargains-as-oil-climbs-and-investors-focus-on-the-fed-4868984. When importing dollar-denominated crude oil, the yen-denominated burden is influenced by both crude oil prices and exchange rates.
If high crude oil prices and a weak yen overlap, it becomes a factor that pushes up costs, but the way the impact appears differs depending on forward exchange contracts and purchasing agreements. When looking at the ripple effect on households, it is also important to note that there is a time lag between import prices and retail prices.
4. The Bank of Japan improves its assessment of 2 regions, but the burden of prices remains on consumption

The Bank of Japan’s October Sakura Report revised upward its economic assessment for Tohoku and Shikoku, while keeping the remaining 7 regions unchanged. While recovery or picking up is reported in all regions, the impact of rising prices is also noted in the assessment of private consumption.
Bank of Japan Regional Economic Report: https://www.boj.or.jp/research/brp/rer/rer261008.htm. An improvement in economic assessment does not mean that every household has more room in their daily life.
Even if improvements in employment and income support spending, rising living costs can become a burden. Going forward, I would like to confirm the relationship between wages and prices, and the spread of consumption by region.
It is not possible to conclude the next Bank of Japan policy change based on this report alone.
5. US stocks fall back, organizing crude oil, interest rates, and exchange rates by industry

The NY Dow on October 7 was down 341.41 dollars to 51,179.87 dollars, and the Nasdaq Composite was down 61.20 points to 27,538.69. Minkabu points out the relative overvaluation of stocks due to high interest rates.
MINKABU PRESS market report: https://news.livedoor.com/article/detail/32515481/. When organizing the impact on companies, it is easier to understand if you separate the costs due to high crude oil prices, financing due to interest rates, and changes in earnings due to exchange rates.
For companies that use a lot of fuel and companies that supply energy, the impact is different even with the same high crude oil prices. You cannot determine the performance of each company or the future direction of stock prices solely from the decline in the index.
6. Future points of interest are the US CPI on October 14 and the spread of price increases

The US September CPI is scheduled to be announced on October 14 at 21:30 Japan time. US Bureau of Labor Statistics release schedule: https://www.bls.gov/schedule/news_release/cpi.htm.
The next FOMC meeting is scheduled for October 27–28, U.S. time. FRB meeting schedule: https://www.federalreserve.gov/monetarypolicy/fomccalendars.htm.
Moving forward, the key points to check will be not only the headline index but also price movements excluding energy, and whether price increases are spreading across a wide range of items. In Japan, we can assess the impact on daily life by tracking the yen exchange rate, import costs, and their subsequent reflection in retail prices.
It is important to distinguish between scheduled announcements and unknown results, and to avoid jumping to conclusions about additional interest rate hikes or the direction of the market.
