Banks to gain extra W27tr in lending room as household debt target doubles

South Korea's financial regulator will double its household debt growth target for this year — from 1.5 percent to 3 percent — to prevent blanket lending caps from choking off funds needed for housing supply and move-ins. With the outstanding household loan balance at roughly 1,800 trillion won ($1.27 trillion), the adjustment creates about 27 trillion won in additional lending capacity beyond what was originally planned. The Financial Services Commission said the extra room will be directed toward relocation loans, interim-payment loans and balance loans, as well as financing for young borrowers and genuine homebuyers, while controls on speculative lending will be tightened.

The FSC announced the measures Thursday as part of a comprehensive financial package aimed at stabilizing the real estate market.

The adjustment will significantly expand the volume of household lending that financial institutions are permitted to manage.

"We estimate the household loan balance at around 1,800 trillion won," an FSC official said. "Applying a 3 percent growth target puts the increase at around 60 trillion won." A straightforward calculation based on the 1,800 trillion won figure puts the 3 percent increment at roughly 54 trillion won — about 27 trillion won more than the roughly 27 trillion won implied by the original 1.5 percent target. The regulator estimates the net additional lending room at around 30 trillion won.

The actual additional capacity will vary by institution. The FSC said at a briefing that because each financial company's existing volume targets and year-to-date loan growth differ, the headroom unlocked by the adjustment will not be uniform across the sector.

The additional lending capacity will be focused on financing at each stage of housing supply. Mortgage loans tied to housing supply — including relocation loans for reconstruction and redevelopment sites and interim-payment and balance loans for newly built move-in complexes — will be tracked separately from each institution's overall household loan volume targets starting in the second half of this year. The move is designed to stop lenders from cutting these loans first when trying to meet their volume caps, which has been causing disruptions to pre-sales and move-ins.

FSC Chairman Lee Eok-won, speaking at a joint briefing held Thursday at Government Complex Seoul, said the regulator would manage overall household debt levels while ensuring a smoother flow of credit for housing supply and genuine demand. "We will carefully manage volume targets for loans linked to new housing supply — such as relocation and balance loans — so that pre-sales and move-ins can proceed without disruption," he said.

Loans for young borrowers and non-homeowners with genuine housing needs will also be shielded from tightening under the volume management framework. The FSC plans to channel the expanded lending capacity toward housing stability for young people and relief for genuine buyers facing financing difficulties, while keeping mortgage supply at necessary levels. Unsecured personal loans, which have been growing faster than last year, will be managed separately through voluntary controls by financial institutions.

The expanded cap does not signal a shift away from the overall household debt management stance, the FSC stressed. With the household debt-to-GDP ratio standing at 88.6 percent at the end of last year, the regulator said it would maintain its broader management posture. Core rules — including a 40 percent loan-to-value ratio in regulated zones, a 40 percent debt service ratio for banks, and mortgage limits by housing price tier — remain unchanged.

Controls on speculative lending will be tightened. Non-resident single-homeowners with speculative intent will be added to the list of those barred from jeonse loan guarantees, and the guarantee coverage ratio for jeonse loans to single-homeowners in the Greater Seoul area and regulated zones will be cut from 80 percent to 70 percent. These jeonse loan restrictions take effect Jan. 1 next year.

Debt service ratio income calculations and capital requirements on bank mortgages will also be tightened from next year. Where income has spiked sharply due to one-off bonuses, a two-to-three-year average will be applied instead. Higher risk weights will be imposed on large, high-DSR loans and on mortgages for high-priced homes with high loan-to-value ratios. The FSC said its approach is to give more room on overall volume while applying stricter oversight to speculative and high-risk lending.
