📊 Policy Evaluation

Assessment of major housing policy interventions and their effectiveness in Seoul

Policy Timing vs Price Trends

  • Delayed intervention timing
    Policies were often introduced after price increases had already begun, limiting their impact.
  • Demand-side focus reinforced expectations
    Repeated tightening measures strengthened expectations of further price increases, sustaining demand.
  • Local demand pressures remained unaddressed
    High-demand areas with strong education and amenities continued to drive price growth.
