Highlights

Consumer inflation in Tokyo, the leading indicator of the national average, decelerated further in two key reading in October as renewed utility subsidies have capped electricity and natural gas prices. The core reading (only fresh food is excluded) posted a 1.8% increase after slowing to 2.0% in September from 2.4% in August, as expected. The year-on-year rise in the total CPI also slowed further to 1.8% from 2.1% (revised from +2.2%), coming in just under the median forecast of 1.9%. The annual rate for the core-core CPI (excluding fresh food and energy) unexpectedly rose to 1.8% from 1.6% against consensus of being steady at 1.6%.

Energy costs added only 0.12 percentage point to the total CPI, down from +0.44 point in September while processed food prices lifted the index by 0.87 point, up from +0.64 point the previous month. The slower CPI rise in October was also due to a drop in internet user fees to zero on year from +8.0% in September, pushing down the index by 0.05 point.

The Bank of Japan is focused on medium-term inflation outlook and its process of raising interest rates gradually toward more normal levels from around zero percent is not dictated by CPI data. The bank is widely expected to stand pat next week but is seen acting in December with a 25 basis point rise after conducting its first rate hike in 17 years in March and following up in July.

Definition

The Consumer Price Index (CPI) is a measure of the average price level of a fixed basket of goods and services purchased by consumers. Annual changes in the CPI represent the rate of inflation.

The Tokyo CPI data covers consumer prices in the capital’s 23 wards located in the eastern part of the Tokyo Prefecture but excludes the 26 cities and other smaller municipalities that occupy larger areas in other parts of the province (islands in the Pacific Ocean are also excluded). It is a leading indicator of the national average CPI as it is released about a month ahead of the national data. The survey for the Tokyo CPI is conducted on one day around the 12th (Wednesday, Thursday or Friday) each month and its results are released toward the end of the same month or early in the following month.

The national CPI has a larger energy weight of 712 out of 10,000, compared to 470 in the Tokyo data, because the shares of consumption of electricity, gasoline and heating oil tend to be bigger in the rural areas. There is only a slight difference in the weighting of food excluding perishables between the national data (2,230) and the Tokyo data (2,144).

Description

The CPI has been in the spotlight as Japan struggled to make its way out of deflation. It is now closely monitored because the recent spike in energy and commodity markets and supply chain constraints during the global pandemic boosted Japan’s inflation rate to the highest in over four decades in 2022.

The report tracks changes in the price of a basket of goods and services that a typical Japanese household might purchase. The preferred measure is the year over year percent change. Markets will typically pay more attention to the core measure that excludes only fresh food because volatile food prices can distort overall CPI. A second core measure that excludes energy as well is also available. As the most important inflation indicator, the CPI data are closely monitored by the Bank of Japan. Rising consumer prices may prompt the BoJ to raise interest rates in order to manage inflation and slow economic growth. Higher interest rates make holding the yen more attractive to foreign investors, and this higher level of demand will place upward pressure on the value of the yen.

An investor who understands how inflation influences the markets will benefit over those investors that do not understand the impact. Inflation is an increase in the overall prices of goods and services. The relationship between inflation and interest rates is the key to understanding how indicators such as the CPI influence the markets and your investments.

Inflation (along with various risks) basically explains how interest rates are set on everything from your mortgage and auto loans to government securities. As the rate of inflation changes and as expectations on inflation change, the markets adjust interest rates. The effect ripples across stocks, bonds, commodities and your portfolio, often in a dramatic fashion.

By tracking inflation, whether high or low, rising or falling, investors can anticipate how different types of investments will perform. Over the long run, the bond market will rally (fall) when increases in the CPI are small (large). The equity market rallies with the bond market because low inflation promises low interest rates and is good for profits.
