BoK: South Korea Sept Inflation Eases, Core Pressures Persist
The Bank of Korea forecasts a moderation in headline inflation for September 2023. This change follows a fading statistical base effect. However, underlying price pressures, particularly in core items, persist.

Headline Inflation Moderates
South Korea's central bank projects a moderation in headline inflation for September 2023. This forecast reflects a diminishing "base effect", Bank of Korea Deputy Governor Lee Ji-ho stated. A base effect describes a statistical distortion. It occurs when comparing current data to an unusually high or low previous period.
Telecommunications company discount programmes in August 2022 depressed prices. This made August 2023 inflation appear higher year-on-year. The Bank of Korea expects this statistical distortion to fade in September 2023.
August 2023 Figures Show Rebound
Government data showed South Korea's consumer prices rose 3.1 percent year-on-year in August 2023. Elevated oil prices contributed to this increase. Higher mobile service subscription charges also played a part. These charges reflected the base effect from 2022's large-scale discounts. The August 2023 figure reversed a previous trend.
It followed a 2.8 percent year-on-year rise in July 2023. Earlier, prices increased 3.1 percent in May 2023 and 3.2 percent in June 2023.
Core Pressures Remain Elevated
Despite the expected easing of headline inflation, underlying price pressures remained high in August 2023. Core inflation, which excludes volatile food and energy prices, advanced 3.4 percent year-on-year. This marked its highest level since May 2023. In May 2023, core inflation rose 3.8 percent.
The persistence of core inflation reveals continued demand or structural cost pressures within the economy, requiring careful monitoring.
Persistent core inflation in South Korea indicates ongoing cost pressures for businesses. Companies may face sustained input expenses, impacting profit margins. This situation complicates the Bank of Korea's monetary policy decisions. While headline inflation may ease, the central bank must weigh underlying price trends.
For regional investors, South Korea's core inflation reveals continued domestic price challenges. These conditions could influence future interest rate expectations.
