Financial Services Commission Enforces Stage-2 Stress DSR Rules to Stabilize Household Mortgage Debt
The Financial Services Commission (FSC) applied a 1.20 percentage point stress rate to Seoul metropolitan area bank mortgages and 0.75 percentage points to non-metropolitan loans under Stage-2 DSR rules.
📊 Key Verified Figures & Units
Under the macroprudential household credit framework announced by the Financial Services Commission (FSC) and the Financial Supervisory Service (FSS), commercial banks calculate borrower Debt Service Ratio (DSR) limits by adding a stress buffer rate to current variable or mixed mortgage rates.
For residential properties in the Seoul Metropolitan Area (Seoul, Gyeonggi, Incheon), a 1.20%p stress rate applies, while regional mortgages outside the capital area carry a 0.75%p stress buffer. Total annual principal and interest payments cannot exceed 40% of verified annual income for commercial bank loans.
The Bank of Korea cited the moderation in metropolitan mortgage growth following Stage-2 Stress DSR implementation as a key factor enabling the Q4 benchmark policy rate reduction to 3.25%.
