Interest Rates Keep Climbing

The credit card loan market is experiencing significant rate increases, with particularly concerning implications for low-credit consumers.

Average credit card loan interest rates reached 14.83% in March 2025, up 0.19 percentage points from February (14.64%)
This represents a 0.37 percentage point increase compared to the same period last year (14.46% in March 2024)
The current rates mark the highest levels since late 2022, creating a substantial burden for borrowers

The Growing Credit Gap

The disparity between high-credit and low-credit borrowers has widened, potentially exacerbating financial inequality.

Low-credit borrowers (credit scores below 700) now face average interest rates of 17.66%, a 0.32 percentage point increase from a year ago
In stark contrast, high-credit borrowers (scores above 900) enjoy significantly lower rates of 11.89%, with no increase during the same period
This 5.77 percentage point gap highlights the growing financial divide between different consumer segments

Multiple Debt Burden Reality

Many Korean consumers are carrying loans from multiple lenders, creating a complex web of financial obligations.

More than half of all credit card loan users have concurrent loans from three or more financial institutions
This multi-lender approach often indicates consumers are using new loans to service existing debt
The delinquency rate reached 1.65% last year, the highest level in a decade, signaling increasing financial distress

Regulatory Pressures Driving Market Changes

Financial policies aimed at controlling household debt are significantly impacting the credit card loan landscape.

The rapid increase in rates is largely attributed to surging yields on specialty financial bonds, which fund credit card loans
Financial authorities’ household debt control measures have led card companies to both raise rates and adjust their loan supply
These regulatory pressures are intended to cool the overall debt market but are creating immediate challenges for borrowers

The consistent rise in credit card loan interest rates places an increasingly heavy burden on Korean consumers, particularly those with lower credit scores. As this trend continues, there’s growing concern that more borrowers may be forced to seek loans outside the regulated financial system. How will policymakers balance debt control with consumer protection in this evolving landscape?
