The keyword for this week (July 6–12) in Korea’s property market was divergence. Even as banks quickly raised their lending bar, Seoul apartment prices kept climbing; in the provinces, by contrast, unsold homes piled past 60,000 units. A market being squeezed by credit rules and one where prices are rising or inventory is stacking up appeared side by side within a single country. Today I’ll wrap up the week along three axes — loans, supply, and polarization — and preview a week ahead loaded with both interest rates and policy. 🏠

TL;DR

  • KB Kookmin Bank halved its maximum home-purchase mortgage from 600M to 300M won on July 10, applying it uniformly even in non-regulated areas — with signs the move could spread across the banking sector.
  • Under the June 27 rules, disbursements of the Didimdol and Beotimmok policy loans plunged 37–52% year on year — with prices outrunning the loan caps, the “sub-600M-won Seoul apartment” has all but vanished.
  • May’s nationwide unsold total was 65,239 units (46,638, or about 71%, in the provinces); so-called “toxic” post-completion unsold homes reached 29,350 — Seoul’s surge and provincial inventory buildup coexist.
  • Week ahead: ministry-by-ministry public forums on 7/14–16 (supply, finance, tax), the BOK Monetary Policy Board on 7/16 (a hike from 2.50% to 2.75% looks likely), the presidential housing forum on 7/23, and a tax overhaul due in late July–early August.

🏦 The Week’s Biggest Variable — the Credit Squeeze KB Set Off

What shook the property market most this week came not from price data but from the bank teller’s window. On July 10, KB Kookmin Bank halved its maximum home-purchase mortgage from 600M to 300M won. What amplified the impact was that it applied the 300M-won cap uniformly even in non-regulated areas that previously had no ceiling. In effect, the bank bolted the door tighter than the regulator’s own limits (600M won under 1.5B, 400M won for 1.5B–2.5B, 200M won above 2.5B).

Behind it lies surging household debt. As of the end of June, banks’ household loan balance stood at 1,189.4 trillion won, up 7.6 trillion won in a single month — the largest monthly increase in one year and ten months, since the August 2024 debt surge. With transactions rising in the greater Seoul area and demand for interim and balance payments on presales building, the banking sector moved preemptively to tap the brakes. The bank frames the step as precautionary rather than a response to hitting a lending ceiling, but the shock to genuine buyers is far from small.

The catch is that this is not confined to KB alone. Shinhan Bank exhausted its new-loan intake quota through loan brokers within a week this month and temporarily suspended those loans, and Hana Bank halted broker-channel mortgage intake starting with next month’s disbursements. That is why observers see the cap cuts potentially spreading across the sector. (Details in KB halves its mortgage cap from 600M to 300M.)

🪜 Policy Loans Are Blocked Too — Why the “Sub-600M Seoul Apartment” Disappeared

It’s not just private lending that tightened. Policy loans, which served as a ladder for ordinary and genuine buyers, also came under scrutiny this week. The heart of the problem: as prices climbed past what policy loans can cover, the apartments you can actually buy with that money have effectively vanished in Seoul.

While the June 27 rules trimmed the Didimdol and Beotimmok loan caps, KB data show Seoul’s median apartment sale price climbed to 1.255 billion won last month. When the Didimdol loan first launched in 2014, the price ceiling was 600M won; over that span, Seoul’s median sale price tripled from 474 million to 1.255 billion won. The “sub-600M-won apartment” that policy loans target has all but disappeared in Seoul.

The numbers make the contraction plain. Per HUG data, Didimdol disbursements for July 2025–May 2026 came to 15.5411 trillion won, down 37.4% from the prior year (24.8349 trillion won); Beotimmok fell 52.3% to 8.7343 trillion won. Policy funds available to genuine buyers were cut nearly in half in a single year. (Related: The vanishing sub-600M Seoul apartment)

🌗 Seoul Surges, the Provinces Sit on 65,000 Unsold Homes — “One Roof, Two Markets”

Another face the week’s data revealed was regional polarization. Prices jumped in Seoul and popular greater-Seoul areas, while in the provinces unsold homes piled up — the exact opposite, at the same time.

By the Ministry of Land, Infrastructure and Transport’s May housing statistics, nationwide unsold homes numbered 65,239, of which the provinces accounted for 46,638 (about 71%). In particular, post-completion unsold homes — classed as “toxic” because they remain unsold even after construction is finished — reached 29,350, and 83.6% of them, or 24,522, were concentrated outside the capital region. Inventory clustered in areas such as Busan (8,292) and South Chungcheong (8,213).

Over the same period, Seoul went the other way. Popular-area demand held up even as loans tightened, and in the prior week Seoul apartment sale transactions overtook jeonse transactions for the first time in four years — the “rather buy than pay jeonse” trend. Seoul, where money is being cut off yet buyers still crowd in, and the provinces, where cuts fail to draw buyers, split in opposite directions.

🧱 The Root Cause Is the “Supply Cliff” — Move-ins Rise, Yet the Annual Total Is a 13-Year Low

Behind Seoul prices holding up despite the credit squeeze lies, ultimately, a supply shortage. The move-in volume figures confirmed this week capture the paradox well. Second-half volume does rise above the first half, but on an annual basis it remains historically scarce.

Seoul apartment move-ins in 2026 roughly double from 6,145 units in the first half to 12,330 in the second. Yet the annual figure comes to just 18,475 units — 56.5% of 2025’s 32,703, or roughly half. Nationwide, too, the figure of 183,124 is down 22.5% from a year earlier, the lowest since 2013 in 13 years. Because a drop in construction starts feeds through to move-ins with a two-to-three-year lag, concerns about a supply shortfall after 2027 only grow. (Related: Second-half move-ins double, yet the supply cliff remains)

When demand-suppressing rules meet insufficient supply, the rules’ effect tends not to last in popular areas and instead fuels a flight to a single “solid” home. The structural backdrop to the market not buckling much this week under the credit squeeze lies here.

🔭 What to Watch Next Week (7/13–19)?

Next week is a “policy super-week” with rates and housing policy stacked together. If this week confirmed the divergence in market indicators, from next week the government and the Bank of Korea begin to point the way.

First, ministry-by-ministry public forums run from July 14 to 16. The Ministry of Land, Infrastructure and Transport (supply), the Financial Services Commission (finance), and the Ministry of Economy and Finance (tax) each spend a day hearing from experts and the public — and the outline of the comprehensive package due late this month may well emerge here.

Next, the Bank of Korea’s Monetary Policy Board meets on Thursday, July 16. Market experts expect a 0.25-percentage-point hike from the current 2.50% to 2.75%, and some surveys project this hike as effectively unanimous. It follows June consumer prices coming in at 3.2%, well above the 2% target, compounded by improving growth and the burden of a weak won. A rate rise, layered onto the credit squeeze, raises interest costs — no small variable for housing demand.

And on Thursday, July 23, President Lee Jae-myung is set to attend a housing grand forum in person. Spanning supply, finance, and tax, it will synthesize views gathered at the earlier ministry forums to gauge policy direction. Reform of holding and transaction taxes is also cited as a subject for discussion. Because the tax overhaul must be prepared in late July–early August under statutory timing, the forum’s outcome may feed into the final plan.

🧭 Takeaway — A Week of Squeeze vs. Hold, a Week for Policy to Answer

This week laid bare how many ways the property market has split. Banks tightened lending and policy loans shrank too, yet popular Seoul areas held firm while unsold homes piled up in the provinces. It can be summed up as a standoff between demand-suppressing rules and the supply shortage propping the market up.

Next week is the first in which the government and the Bank of Korea point a direction into that standoff. With a rate hike, ministry forums, the presidential grand forum, and the month-end tax overhaul packed tightly together, mid-July has a strong chance of becoming the pivot for the second half’s housing trend. Worth watching calmly, in particular, is how the three strands — tax, supply, and finance — mesh, and whether cards emerge that can actually narrow regional polarization.
