# South Korean mortgage rates, costs and credit stress > Live situation record from CLSTR: https://clstr.news/situations/south-korean-bond-yields-and-mortgage-rates > Updated: 2026-08-03T02:39:28.000Z. Sources: 12. Developments: 10. In early July 2026 South Korean banks saw mortgage rates climb, with fixed‑rate loans ranging from 4.39 % to 7.33 % – the highest band in more than three years as global bond yields rose. The Financial Services Commission (FSC) adjusted the debt‑service‑ratio (DSR) framework on 15 July, lowering the weight of one‑off bonuses, extending income averaging to three years and keeping the DSR ceiling at 40 % to curb household‑loan growth toward its 1.5 % target. KB Kookmin Bank halved its mortgage‑loan ceiling, and on 20 July the Bank of Korea raised its base rate, widening mortgage rates at the five largest banks to a 4.77 %–7 % band. Commercial‑real‑estate financing entered a higher‑cost phase, and loan delinquency rose to 0.67 % at the end of May, the highest in nine‑and‑a‑half years. Subsequent weeks added pressure: regional banks lifted rates further as long‑term bond yields hit multi‑year highs; a 0.25‑point base‑rate rise was projected to add about 1.8 trillion won to borrowers’ annual interest costs, with larger hikes magnifying the burden. The rate hike spurred large deposit inflows and widened spreads on office and logistics‑center loans. While mortgage limits tightened, non‑mortgage credit expanded beyond targets, pushing overall household‑loan balances about 2.3 trillion won above government goals and nudging delinquency higher. Banks promoted DSR‑linked “repayment‑condition” mortgages and community micro‑loans to help borrowers refinance personal credit, while jeonse‑loan rates breached 6 % and estimated non‑performing loan losses hit a seven‑year high, foreshadowing further tightening of housing‑related credit. ## Timeline ### 2026-08-03: South Korean banks face record 1.2 trillion‑won loan losses as jeonse rates top 6% South Korean banks report a record 1.2 trillion‑won loan loss and watchlist exposure, while jeonse loan rates climb past 6% amid rising market rates. 3 sources. https://clstr.news/cluster/south-korean-banks-face-record-12-trillionwon-loan-losses-as-jeonse-rates-top-6 ### 2026-07-30: South Korean borrowers use DSR‑linked mortgages and community microloans to expand credit Korean banks push DSR‑linked mortgage loans to boost limits, while a nonprofit offers interest‑free microloans to low‑income borrowers, expanding credit access. 2 sources. https://clstr.news/cluster/south-korean-borrowers-use-dsrlinked-mortgages-and-community-microloans-to-expand-credit ### 2026-07-30: South Korea to survey and fix ‘marriage penalty’ in housing loans South Korea will investigate the “marriage penalty” that blocks many couples from policy housing loans, aiming to revise income limits and ease home‑ownership hurdles. 2 sources. https://clstr.news/cluster/south-korea-to-survey-and-fix-marriage-penalty-in-housing-loans ### 2026-07-28: South Korea's fixed‑rate mortgage share hits 12‑year low as banks raise loan rates KB Kookmin Bank lifts loan rates by up to 0.53 pp, and the share of fixed‑rate mortgages in South Korea drops to a 12‑year low as borrowers favor cheaper variable rates amid rising household‑loan costs. 2 sources. https://clstr.news/cluster/south-koreas-fixedrate-mortgage-share-hits-12year-low-as-banks-raise-loan-rates ### 2026-07-26: South Korean banks curb variable‑rate mortgages as regulators weigh loan relief for young buyers South Korean banks halted variable‑rate mortgages to meet loan caps, while regulators consider exempting youth and first‑time buyers from total‑loan limits and easing LTV rules for new homes. 6 sources. https://clstr.news/cluster/south-korean-banks-curb-variablerate-mortgages-as-regulators-weigh-loan-relief-for-young-buyers ### 2026-07-21: South Korean banks face surge in non‑mortgage credit loans and rising delinquency rates South Korean banks’ non‑mortgage loan portfolios surged past targets by about 2.4 trillion won as mortgage lending tightened, while loan delinquency rates rose to 0.67% – the highest in nine‑and‑a‑half years. 4 sources. https://clstr.news/cluster/south-korean-banks-face-surge-in-nonmortgage-credit-loans-and-rising-delinquency-rates ### 2026-07-20: South Korea's rate hikes spur deposit inflows and widen commercial real‑estate loan spreads Bank of Korea’s rate hikes pushed mortgage rates above 7% and spurred a 16 trillion‑won surge into term deposits, while commercial real‑estate loan spreads widened by 70 basis points, tightening financing. 7 sources. https://clstr.news/cluster/south-koreas-rate-hikes-spur-deposit-inflows-and-widen-commercial-realestate-loan-spreads ### 2026-07-15: South Korea cuts performance‑bonus weight in mortgage DSR to curb housing loan growth South Korea reduces performance‑bonus weight in mortgage DSR calculations, moving to a three‑year income average to limit loan growth and tighten high‑risk mortgage rules. 5 sources. https://clstr.news/cluster/south-korea-to-tighten-mortgage-dsr-rules-reduce-performancebonus-weight ### 2026-07-15: South Korea loan interest hikes add up to trillions in borrower costs A 0.25‑point rate rise in South Korea could add 1.8 trillion won to mortgage and small‑business loan costs, pushing average borrower payments higher and raising default risks. 2 sources. https://clstr.news/cluster/south-korea-loan-interest-hikes-add-up-to-trillions-in-borrower-costs ### 2026-07-03: South Korean mortgage rates spike as long‑term bond yields hit multi‑year highs South Korean banks raise mortgage rates to 4.4‑7.3% as global long‑term bond yields surge, tightening credit for households with massive debt. 3 sources. https://clstr.news/cluster/south-korean-mortgage-rates-spike-as-longterm-bond-yields-hit-multiyear-highs --- Cite as: South Korean mortgage rates, costs and credit stress.
