Highlights

South Korea's headline consumer price index rose 2.4 percent on the year in October, picking up from an increase of 2.1 percent in September. This is the strongest headline inflation since July 2024. The index rose 0.3 percent on the month after increasing 0.5 percent previously. Core CPI, excluding food and energy, rose 0.4 percent on the month after a previous increase of 0.5 percent, with the year-over-year increase picking up from 2.0 percent to 2.2 percent, also a multi-month high. Higher core inflation in October was largely driven by bigger increases in clothing and household goods prices. Food prices and transport costs also rose at a faster pace.

At the Bank of Korea's most recent policy meeting, held last month, officials left the main policy rate on hold at 2.50 percent. Although they reiterated that they have a rate cut stance, officials again stressed that they will adjust the timing and pace of any further rate cuts based on incoming data.

Market Consensus Before Announcement

CPI expected up 0.2 percent on the month in October versus an increase of 0.5 percent in September. On year, expectations call for an increase of 2.2 percent versus 2.1 percent in September.

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.

Description

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 mortgages 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.
