Korea Apartments, Loans and Jeonse — 2026-09-26

Seoul apartment prices rose for an 85th straight week, matching the Moon Jae-in-era record streak, while Gangnam districts slid. The Bank of Korea escalated warnings on household debt, flagging housing-related loan risk of over 1,365 trillion won and property finance exposure of 4,307.7 trillion won. Jeonse supply continued to dry up, pushing tenants toward expensive monthly rent and creating a relocation squeeze in redevelopment zones.

Seoul apartments post 85th straight weekly gain, matching record

Seoul apartment sale prices rose 0.13% in the week ended Sept. 21, the 85th consecutive weekly increase, matching the longest rising streak on record from the Moon Jae-in era. Gyeonggi prices accelerated from 0.18% to 0.23%, led by the "semiconductor belt," while Gangnam districts declined. The cumulative 17.47% rise over this streak far exceeds the 7.71% seen during Moon's record run, driven by demand shifting to mid-priced and northern Seoul districts.

The jeonse market showed the same Gangnam split: nationwide jeonse prices rose 0.10% week-on-week and Seoul 0.19%, but Seocho fell 0.19% on move-in supply from large complexes in Jamwon and Banpo, while Nowon and Seongbuk stayed strong.

Bank of Korea flags housing loan risk above 1,365 trillion won

The Bank of Korea warned that potential losses tied to household housing loans now exceed 1,365 trillion won, as buyers pivot to cheaper homes while rent and loan exposure mount. BOK official Jang also warned the Seoul home-price surge could fuel further household loan growth, keeping the central bank watching for additional tightening.

Separately, BOK said total property finance exposure reached 4,307.7 trillion won at the end of the second quarter.

Jeonse drought pushes tenants into monthly rent

Seoul apartment contracts with monthly rent above 3 million won jumped 9.7% this year as jeonse prices climbed for an 84th straight week — now exceeding the Moon-era peak. All 10 real estate experts surveyed by Money Today expect both Seoul jeonse and monthly rents to rise over the next year, citing shrinking listings as the key driver. Analysts say rising rents are nudging tenants into buying.

Jamsil Jugong 5 relocation squeeze

Gangnam's rebuilding wave is creating a scramble for rentals: over 2,100 households at Jamsil Jugong 5 must relocate from late next year, but only 528 jeonse listings remain across major Jamsil complexes. Owners facing relocation before reconstruction are expected to tighten the jeonse market further in Gangnam-adjacent areas.

Government unveils 1.19 million public housing plan

On Sept. 21, the government announced plans to supply 1.19 million public sale and rental homes through 2030, concentrated in the Seoul metropolitan area, in response to mounting housing price pressures.

Local view

Hankyoreh noted the 85-week streak ties the record set under the Moon government, with Gangnam 3 districts in a downtrend while northern Seoul leads gains, and experts citing the jeonse crisis and liquidity as sustaining momentum. Money Today flagged interest rates as the biggest variable for how long the longest rally continues. Financial News reported the share of borrowers whose debt-service payments exceed annual income has turned upward after three and a half years — only 71.1% of borrowers have DSR below 40%, yet they hold just 39.8% of outstanding loans.

Context & numbers

• Seoul apartment prices: +0.13% week to Sept. 21; 85-week cumulative +17.47%
• Nationwide jeonse +0.10%, Seoul jeonse +0.19% in the third week of September
• KRIHS finds a 0.25pp rate hike cuts apartment prices 1.2% within six months
• Consumer sentiment rose to 106.6 in September; housing price outlook CSI held at 125 for a sixth month despite President Lee's crash warning
• Suwon's Yeongtong district prices rose 1.09% in a week, fueled by Samsung Electronics in-house housing loans

On the radar

• BOK officials warning of rising loan demand could signal further DSR or rate tightening — watch the rate-path debate into October.
• Jamsil Jugong 5 relocation precipitates a Gangnam-area jeonse shortage from late 2027, with listings already at 528.
• Multiple-home owners staying put: BOK finds high price expectations blunt tax cuts' incentive to sell — watch supply of second-hand listings.
• Metropolitan price-gain streak at a record-equal 85 weeks; a Gangnam-led dip versus northern-Seoul strength remains the split to watch (rumored among analysts that Gangnam sales weakness could spread, unconfirmed).
