South Korea's Financial Services Commission has published the government’s 2026 household debt management plan, aiming to keep total household credit growth tightly capped while reducing incentives for leveraged real estate investment through stricter mortgage management and expanded coverage of loan regulations. The plan sets a 1.5% household debt growth target for 2026 and adopts a medium- to long-term roadmap to reduce the household debt-to-GDP ratio to 80% by 2030. It also envisages gradually reducing the share of policy-based loans to 20% from about 30%, applying penalties to financial companies that missed 2025 targets (including deducting prior-year surplus loan amounts from 2026 limits), and setting MG Community Credit Cooperatives’ 2026 target at zero growth with possible further penalties affecting 2027 targets. A separate management target for home mortgage lending will be introduced, alongside monthly and quarterly targets to reduce end-year tightening, while maintaining supply of policy microloans and mid-range interest loans for lower-income and vulnerable borrowers. For multi-home owners, mortgage maturity extensions on apartments in the Seoul metropolitan and speculation regulated areas will in principle be disallowed from 17 April 2026, with limited exceptions including extensions until lease expiry where the home is rented and the lease was signed before 1 April 2026; related procedural incentives in the land transaction permit system are expected to take effect in April following a revision to the Enforcement Decree of the Act on Report on Real Estate Transactions. Online peer-to-peer lending firms will become subject to loan-to-value limits from 2 April 2026 (40% in the Seoul metropolitan and speculation regulated areas and 70% elsewhere) and to tiered mortgage amount caps of KRW 600 million (homes valued at KRW 1.5 billion or below), KRW 400 million (above KRW 1.5 billion up to KRW 2.5 billion), and KRW 200 million (above KRW 2.5 billion). Enforcement will be stepped up through inspections of loan-rule breaches, building on findings from the second half of 2025 that included 127 business-loan misuse cases totaling KRW 58.75 billion and 2,982 household-loan regulation violations. Financial companies and the Financial Supervisory Service plan a sweeping review of business loans issued since 2021, with immediate collection of misused loans and referrals to investigative agencies, while the National Tax Service will examine tax evasion linked to business-loan misuse; longer loan access restrictions are also planned for rule-breakers. Measures requiring no administrative actions will be implemented immediately, other steps will be advanced as early as possible, and the FSC signaled it may introduce additional loan regulations as needed while continuing work on previously announced measures such as expanded debt service ratio rules and structural improvements in household lending.
