South Korea’s financial authorities are moving to tighten the growth trajectory of household lending this year, aiming for growth below last year’s 1.8 percent. They plan a separate cap on housing loans and are weighing a potential increase of up to 25 percent in mortgage risk-weighted assets, while restricting loan maturities for multi-homeowners and rental operators; non-resident single-homeowners would be excluded from the new rules. The plan, initially expected by late February, was delayed due to additional adjustments.

The administration intends to curb household loan growth more aggressively by lowering the overall growth cap and reinforcing balance-sheet requirements. Officials have signaled that the plan could entail raising risk weights for mortgage lending and imposing tighter lending standards to keep credit growth in check. The policy direction aligns with stronger regulatory oversight, aiming to prevent rapid increases in household debt over the coming year. Industry data released ahead of the policy show sharp activity at some mutual aid institutions, with Nonghyup’s household lending rising by 3.2 trillion won in January–February and Saemaeul Geumgo increasing by about 1.8 trillion won, underscoring the rapid pace authorities seek to restrain.

The regulators intend to permit new lending only within existing repayment capacity, preventing net growth in household debt for the year. In addition to the aggregate cap, a separate cap for housing loans will be introduced, and mortgage-related RWA could be raised by as much as 25 percent. President Lee Jae-myung’s administration is also expected to unveil measures targeting multi-homeowners and rental operators, restricting mortgage maturities in the capital region and regulatory zones, while excluding non-resident single-homeowners from the current package. Bankers expect these high restrictions to force banks toward more productive finance and away from broad consumer lending, potentially squeezing margins and prompting a shift toward corporate lending.
