South Korean household loans across all lenders rose 6.4 trillion won in October, reversing a 2.2 trillion won decline in September, as banks stepped up mortgage lending and credit loans returned to growth, preliminary data from the Financial Services Commission showed on Wednesday.

The rebound matters for investors in Korean banks, card companies and insurers, and for anyone betting on the direction of the Bank of Korea. The central bank raised its policy rate in July and August to 3%, citing inflationary pressure, and held it in October, according to Yonhap. A fresh rise in borrowing gives rate setters less room to ease and keeps regulators focused on how much banks can lend into next year.

Banks lead, nonbanks turn positive

Banks accounted for most of the increase. Household loans in the banking sector rose 5.0 trillion won in October, up from 0.6 trillion won in September, the FSC said. Nonbank lenders added 1.4 trillion won after shrinking their household books by 2.7 trillion won the month before.

Every nonbank group grew. Specialized credit finance companies, which include card issuers and capital firms, added 0.8 trillion won after a 0.9 trillion won drop. Insurers added 0.3 trillion won, while mutual finance businesses and savings banks each added 0.2 trillion won. All four had contracted in September.

The figures are broader than the 2.77 trillion won rise reported by the five largest banks earlier this month. That count covered only KB Kookmin, Shinhan, Hana, Woori and NH Nonghyup, which together held 783.6 trillion won in household loans at the end of October, according to data compiled by the banks and reported by Yonhap. At those five lenders, mortgage loans rose for a seventh straight month and credit loans climbed 669 billion won to 108.89 trillion won, after a 1.34 trillion won drop in September.

Mortgages rise again, credit loans rebound

Mortgage loans across all sectors rose 4.0 trillion won, up from 3.2 trillion won in September. Banks provided 3.3 trillion won of that and nonbanks 0.7 trillion won. Within the banking sector, banks' own mortgage products grew 2.2 trillion won and policy-based mortgages, which are backed by state housing programs, rose 1.2 trillion won.

The sharper swing came in other household loans. They rose 2.4 trillion won after a 5.4 trillion won fall in September. Credit loans, the unsecured borrowing that tends to track demand for stock investment and consumer spending, rose 1.2 trillion won after a 2.9 trillion won decline. In the banking sector alone, other loans rose 1.7 trillion won after a 2.3 trillion won drop.

September's fall had partly been technical. In its release last month, the FSC attributed the decline mainly to fewer housing transactions and bad debt write-offs near the end of the quarter, when lenders typically clean up their books.

The regulator said October's increase came despite a recent decline in housing transactions. It pointed instead to group lending, the bulk loans that fund buyers in newly built apartment complexes, as previously approved loans were drawn down. Regulators have told lenders to manage group lending separately within their household debt totals.

Regulator says growth remains within target

The FSC said total household lending was still being managed within the annual target it had announced. It has raised that ceiling for household debt growth to 3.0% from 1.5%, according to the September release.

The commission did not signal new curbs. It told financial companies to avoid a broad credit crunch after lending too much in any one period. It said authorities would keep credit available for genuine home buyers and renters, especially young adults and households outside the Seoul metropolitan area.

At the same time, the FSC said it would target speculative demand through strict inspections of illegal practices in the housing market.

For bank shareholders, the pattern is mixed. Faster loan growth supports net interest income at a time when Korea's big financial groups are expanding buybacks. But lending quotas cap how much of that growth banks can capture, and October's jump uses up part of the room left for the final two months of the year.

The next marker is the FSC's November release, which will show whether group lending and credit loans kept the total climbing into the year's final weeks.
