Lowest Household Debt Ratio in 6 Years?… The Truth Behind the 'Optical Illusion' Hidden in the Numbers

AI Summary

The household debt-to-GDP ratio reached its lowest level in 6 years and 3 months at 88.6%, but this is likely an optical illusion caused by an increase in nominal GDP rather than a reduction in debt.

Lately, when watching economic news, one might encounter some welcome tidings: the news that South Korea’s “household debt-to-GDP ratio” has fallen to its lowest level in 6 years and 3 months. Hearing this alone makes it feel as though our households have been diligently paying off debt, making the economy much sounder.

Imagine this: a situation where the interest burden you have to pay every month has decreased, making your heart feel much lighter. But has our household debt actually decreased? Today, I want to talk about the hidden truth that the numbers in economic indicators do not tell you.

Why is this important?

The household debt-to-GDP ratio is like a “health checkup result” that shows how dependent our economy is on debt. A high ratio means the weight of debt households must bear is large relative to the size of the economy. News that the ratio has fallen can appear at first glance as a signal that economic fitness has improved. However, knowing whether this indicator has gone down simply because debt was repaid, or due to other reasons, is essential for grasping our actual economic sentiment.

Easy to understand

To put it simply, let’s say your monthly salary is 3 million won and your debt is 2.7 million won; your debt ratio is 90%. But suppose that one day, your debt remains the same while your salary rises to 3.4 million won. Then the debt ratio drops sharply to about 79%. The important point here is that you did not pay off the debt, but the ratio only lowered because your salary (the scale of the economy) grew.

The recent decline in the household debt ratio is similar to this. According to statistics, South Korea’s household debt ratio in the fourth quarter of 2025 was 88.6%, lower than the previous quarter’s 89.4% [Source 15]. However, experts point out that this is likely an “optical illusion” caused by the increase in the nominal GDP scale itself due to inflation and economic growth, rather than a result of households actually undergoing “restructuring” to reduce debt [Source 1, Source 3].

In other words, it is a story where magic occurred because the entire economy grew, making debt look relatively small, but the actual weight of the debt burdened by our households may not have become lighter.

Where are we now (Current situation)

South Korea’s household debt-to-GDP ratio recorded 88.6%, the lowest level since the third quarter of 2019 [Source 5, Source 17]. Along with this, the government debt ratio also showed the largest quarterly decline in history, showing a general easing of the national debt burden [Source 4, Source 18].

However, do not let your guard down. Looking at past statistics, South Korea has maintained one of the world’s highest household debt levels relative to the size of its economy [Source 8]. Furthermore, there are still concerns about the rapid surge in household debt, as household capital conditions are tight and mortgage loans are increasing again [Source 10].

What will happen in the future?

The key moving forward is whether this figure can lead to “substantive improvement” rather than just an “optical illusion.” Not only external factors like GDP growth but actual debt management, where households themselves reduce debt, must accompany it for our economy’s fundamental fitness to truly strengthen. When looking at economic indicators, it is a time that requires the meticulousness to examine not just the “percentage” result, but how that number was created.

AI Opinion

This indicator is a case showing that if the economy grows, the debt burden can relatively decrease. However, one must remember that just because the numbers have gone down does not mean the weight of debt households actually feel has decreased. When checking the health of our economy, we need the wisdom to look into the substantive content beyond the visible figures.
