Korean banks added 600 billion won in household loans in September against 10.7 trillion won for companies
South Korean banks' household loans grew 600 billion won in September, down from 3.5 trillion won in August, according to Bank of Korea data. Corporate loans rose 10.7 trillion won in the same month, so bank balance sheets grew anyway.

What happened
- Mortgages rose 2.9 trillion won against 4.1 trillion in August, while other loans, including unsecured personal credit loans, fell 2.3 trillion won.
- Lending to large companies grew 7.5 trillion won against 4.9 trillion in August, while loans to smaller firms slowed to 3.2 trillion won from 4.8 trillion.
- Net corporate bond redemptions jumped to 3.4 trillion won from 900 billion in August, with higher market rates adding to issuance costs.
- Household loans at all financial institutions fell 2.2 trillion won, the first monthly decline since December, according to Financial Services Commission data.
Why it matters
- contradiction The causes on offer do not overlap, so they imply different Octobers. Quarter-end write-offs and bonuses reverse; tighter rules and a 3% benchmark rate, Yonhap's explanation, do not.
- decision Banks are adding balance sheet through companies. The Bank of Korea ties part of the large-company gain to bond repayment, so some of the growth refinances existing debt.
- constraint The cushion is thin. Mortgage gains exceed the fall in other loans by only 0.6 trillion won, so a mortgage gain 0.6 trillion smaller would turn the bank total negative.
Banks lent companies 10.7 trillion won in September and households 600 billion, a ratio of about 18 to 1 [9][1][19]. The household side had been sliding for three months. Its monthly gain was 7.6 trillion won in June, 5.5 trillion in July and 3.5 trillion in August [2], so the gain is down 7.0 trillion won, or 92%, since June [15]. Of that 7.0 trillion, 4.1 trillion (about 59%) had come off by August [18].
The reported figure nets two larger moves: a 2.9 trillion won mortgage gain less a 2.3 trillion won fall in other loans leaves 0.6 trillion [17]. "Mortgage loan growth narrowed as jeonse transactions slowed," a Bank of Korea official said [5]. The same official said: "Other loans declined for a second consecutive month on reduced stock investment by individuals, the sale and write-off of bad loans at the end of the quarter and the inflow of holiday bonuses, which pulled down overall loan growth." [14]
We think the quarter-end items explain less than that list suggests. Write-offs and bonuses are timed to the quarter and the holiday, though the sources do not size them, and the slide was already 4.1 trillion won deep before September began [18]. Jeonse is a slower factor: deposit loans for it have fallen for 13 consecutive months since September last year [6]. So we expect October's household gain to print above 600 billion won and still well below June's 7.6 trillion [2].
Yonhap's account differs. It ties the slowdown to tightened lending regulations and higher interest rates [27]. The central bank took its benchmark rate to 3% over two straight meetings in July and August, its first back-to-back hikes since January 2023 [7]. The monthly gain fell from 7.6 to 5.5 trillion won in July, the month of the first hike [2][7]. If October's household gain is again under 1 trillion won, we are wrong and the rates explanation gets the weight. A third path runs through equities: the Bank of Korea counted reduced stock investment among the causes amid a domestic market correction [13], so a recovery would lift credit loans with no change in rules or rates.
Set against the banks' 0.6 trillion won gain, the all-institution fall implies that non-bank lenders cut household loans by about 2.8 trillion won [20], if the two series cover the same loans.
The two reports also disagree on the record. En.sedaily.com calls September a five-month low and the smallest gain since April, when loans rose 2.1 trillion won [21]. That is 1.5 trillion above September's gain [24], so April cannot be the comparison. Yonhap puts March's gain at 0.5 trillion won and calls September the smallest since then [22].
The mortgage balances differ as well: 995.5 trillion won at en.sedaily.com [3] and 955.5 trillion at Yonhap [23]. Adding the 242.6 trillion won of other loans [4] gives 1,198.1 trillion on Yonhap's figure, 0.8 trillion short of the reported total [25], and 1,238.1 trillion on the other [26]. Neither report explains the remaining gap. We take 995.5 to be a typo.
What to watch
- October's Bank of Korea household loan figure: a second gain under 1 trillion won would favor the rates-and-rules explanation over the one-off items.
- Whether other loans fall for a third straight month, which would test the reduced stock investment explanation.
- The next Bank of Korea rate decision after the two hikes to 3%, since further tightening would back Yonhap's explanation.
