Korean homeowners who took out mortgages during the pandemic-era low-rate period are beginning to feel a sharp reset as five-year fixed-rate terms expire and loans move onto higher rates. One reported borrower who took a 350 million won mortgage in 2021 saw monthly principal and interest payments rise from about 1.4 million won to 1.67 million won after the fixed period ended in April.
The pressure can be larger on bigger loans. The persisted source illustrates that a 500 million won mortgage moving from a rate in the 2 percent range to a rate in the 4 percent range can lift monthly repayment from roughly 1.97 million won to about 2.63 million won, depending on loan terms. That is a meaningful increase in household cash outflow even without any change in the amount originally borrowed.
The issue is a delayed consequence of the unusually cheap borrowing environment around 2021. Fixed introductory periods insulated borrowers from subsequent rate increases for several years, but that protection is now expiring for more households. The resulting payment jump can affect consumption, refinancing decisions and the ability of stretched borrowers to absorb other living costs.
A delayed rate shock reaches households
For affected households, the practical question is what rate applies after the fixed term and whether refinancing or repayment adjustments are available. The evidence shows the reset is already reaching borrowers, turning past low-rate mortgages into a current household-finance burden.
