The ten latest chart observations. Change subtracts the previous observation; intervals vary with holidays, release schedules and missing data. A difference in rates or ratios is not an investment return.

Interpretation guide
The Seoul apartment price index: Korea's property benchmark
The Seoul apartment sales price index tracks apartment transaction prices in the capital monthly. Seoul apartments are where Korean property price discovery happens and where policy aims first, so the index leads the national market — moving earlier and harder than the nationwide gauge.
Why Seoul apartments
Even when regional markets diverge, Seoul apartments trade like a single national-demand market. Upcycles start in Seoul and radiate outward; in downturns, a slowing pace of Seoul declines is watched as a bottoming signal.
- A widening Seoul-versus-national gap signals a market consolidating into core locations.
- Gangnam reconstruction prices are the front line of property risk appetite.
- A rising jeonse-to-price ratio signals stronger end-user underpinning.
A battleground of policy and supply
Seoul apartments absorb the full weight of lending rules, taxes, reconstruction regulation, and supply plans. Policy changes move transactions before prices, and the regulation cycle intertwines with the price cycle.
- LTV and DSR lending-rule changes act as an immediate demand switch.
- The completion-supply cycle can be estimated years ahead from past pre-sale volumes.
- Post-tightening transaction cliffs make the price index hard to read for a stretch.
Uses from an equity perspective
Seoul apartment prices compress household wealth expectations and risk appetite into one series. Surges pull household leverage into property and can starve equity flows; slumps weigh on consumer names through a negative wealth effect.
- Seoul price strength plus rising bank household lending is favorable for bank earnings.
- Property-surge FOMO has at times spilled into speculative equity and crypto demand.
