South Korea Should Reconsider Weekly Apartment Price Statistics

The head of the Korea Real Estate Board has publicly expressed reservations about the weekly publication of apartment price statistics, citing internal and external concerns regarding the data's meaningfulness. Lee Heon-wook stated that globally, it is rare for national official statistics to report weekly apartment price trends. This practice, he suggested, could overemphasize market overheating and speculative behavior.

The Korea Real Estate Board releases its "Weekly Apartment Price Trend" every Thursday, which is routinely covered by the media due to high public interest in housing prices. South Korean apartments are often standardized, leading to their treatment like financial products where prices for identical units within the same complex are similar. This environment reportedly allows some speculators to engage in transactions without even viewing the properties.

There are many internal and external issues raised about the meaningfulness of the statistics on weekly trends.

In this context, the board's weekly price announcements may exacerbate excessive market attention and encourage speculative trading focused on short-term price changes. Furthermore, the sensitive reactions from the media and the market could push government housing policies toward prioritizing short-term outcomes, which is undesirable for policies that require significant time to show effects.

Globally, there are almost no cases where weekly trends are announced as official national statistics.

While weekly statistics have served a purpose, such as mitigating confusion caused by opaque private market information and providing a benchmark for genuine buyers, their accuracy is debated. Unlike price quotes from private firms, the board's statistics are based on surveys of property listings, asking prices, and actual transaction data, aiming for higher reliability. However, in areas with no recent transactions, prices are calculated based on asking prices or data from similar apartment complexes, leaving room for accuracy disputes.

Major overseas markets typically do not publish weekly housing price statistics. Most release data monthly or quarterly, primarily based on actual transaction prices, focusing on identifying market trends rather than short-term fluctuations. This approach enhances the reliability of the statistics. The Ministry of Land, Infrastructure and Transport, which commissions these surveys, is reportedly aware of these issues and considering institutional reforms. While a minister previously acknowledged the need to reduce the negative effects of weekly statistics, specific plans have yet to be presented. Given the calls for change from the institution that produces the data, the ministry is now expected to make a decision regarding the revision of the weekly publication system.

If there is a policy change, such as changing the officially recognized national statistics to monthly, we will comply.
