We have already looked at the size of their assets. This time it is the other side of the ledger: debt. Debt is usually read as a signal of poverty — you borrow because you have no money. Yet once you spread out the lawmakers’ liabilities, that intuition flips entirely. It is not that they go into debt because they are poor; the more real estate they own, the more debt they carry.The top 20% of lawmakers by real estate carry ₩1.26 billion in average debt — nearly ten times the bottom 20% (₩130 million).
Why look at debt on its own?
The public officials’ asset disclosure does not reveal only what lawmakers own. Opposite the assets, debt is reported alongside them. Only by subtracting liabilities — loans from financial institutions, debts between private parties — from positive assets such as real estate, deposits, and stocks do you arrive at a person’s net worth. Yet coverage and chatter always fixate on the total of positive assets: who holds how much. The other side of the ledger, debt, is rarely examined on its own, because debt is taken to be a private matter or a sign of hardship.
But set debt beside assets and the opposite of the common intuition appears. The heavily indebted are not the hard-pressed lawmakers but, on the contrary, those who hold the most real estate. This piece sorts the lawmakers who own real estate in the 2025 disclosure into five groups by value (quintiles) and follows how each group’s average debt shifts. The core question is not ‘how much debt did lawmakers take on’ but ‘who takes on the debt.’
As the real-estate quintile rises, debt climbs like a staircase
Line lawmakers up into five groups by real-estate value, and their debt climbs like a staircase. The 1st quintile, with the least real estate (avg. ₩340 million), carries ₩130 million in debt. With each step up, the debt swells steadily, and by the time you reach the 5th quintile (avg. ₩6.29 billion), the average debt is ₩1.26 billion. That is nearly ten times the bottom 20%. It is a textbook leverage curve, with assets and liabilities growing side by side.
The 2nd quintile (real estate ₩720 million) averages ₩280 million in debt and the 3rd (₩1.12 billion) averages ₩290 million — the two middle steps stand almost shoulder to shoulder. But the 4th quintile (₩1.90 billion) jumps a notch to ₩440 million, and the 5th surges again to ₩1.26 billion. The higher you climb, the more debt grows faster than real estate does. The staircase is not evenly spaced; each step grows taller toward the top.
Debt is not want but a lever
Normally debt is a signal of want. But on the lawmakers’ ledger it has to be read the other way around. The fact that debt grows in step with assets means that money was not living expenses but ‘a lever for grabbing hold of even bigger assets.’ You buy real estate on borrowed money, and when that real estate rises in value, you again gain the capacity to take on even more debt. The trace of the better-off borrowing more aggressively to roll their assets over is carved right into this staircase.
This is also how the real-estate market works. The bigger the collateral, the bigger the loan; the bigger the loan, the pricier the asset it can buy. Debt is used not as a weight that drags assets down but as a ladder that lifts them up. Stepping from the 4th quintile to the 5th, real estate jumps more than threefold, from ₩1.90 billion to ₩6.29 billion, and debt jumps nearly threefold alongside it, from ₩440 million to ₩1.26 billion — because the larger the assets, the larger the collateral capacity to raise debt. For a 1st-quintile lawmaker, ₩130 million in debt is a weight; for a 5th-quintile lawmaker, ₩1.26 billion in debt is a tool. The same word, ‘debt,’ carries opposite meanings depending on the quintile.
A trick of the average? Monotonicity answers
So is this staircase a statistical illusion? Averages are easily swayed by a single extreme value. If one or two lawmakers carrying tens of billions in debt sit in the 5th quintile, the ₩1.26 billion average could be inflated. It is a fair objection. But the point of the staircase is not the height of the 5th step; it is the monotonicity — that from the 1st to the 5th quintile it rises without ever dipping once. Even if a handful of large debts pull the average up, the fact that all five steps point the same way does not change. One or two outliers cannot build a five-step staircase.
Slice it by party and the order holds
The same pattern repeats between parties. In 2025, 232 lawmakers reported debt, averaging ₩580 million per person. By party, the People Power Party (PPP) averaged ₩720 million and the Democratic Party (DP) ₩520 million — the side with the larger average real estate also carried the larger debt. It is exactly the same order as the earlier statistics on assets. The ‘assets-track-debt’ pairing seen across the real-estate quintiles holds even when cut by the different yardstick of party. The distribution of debt is less a matter of faction than a function of asset holdings.
Where was that debt borrowed?
Where the debt sits also throws light back on its pairing with assets. This site’s trend tally of debt (by creditor institution) shows lawmakers’ debt reported at ₩82.16 billion in all, across 537 holdings. Note that this tally is a separate aggregation keyed to ‘which financial institution lent it,’ not a cross-tab by real-estate quintile, so its unit differs from the staircase averages above. Ranking the creditors, the institution where the most lawmakers carry debt is Nonghyup Bank (81 lawmakers), and the one with the largest total reported value is Shinhan Bank (₩18.52 billion). The top five (Shinhan, Hana, Nonghyup, Kookmin, Woori) account for about 70% of the total reported value, while debts to capital firms, card companies, and insurers stay in a small tail by amount. By party, the Democratic Party had the most lawmakers reporting debt, at 91. In short, lawmakers’ debt is overwhelmingly concentrated in collateralized loans from mainstream banks rather than private lending — a clue to where the lever for rolling assets is supplied.
Debt as the shadow of wealth
In the end, gaps in assets lead to gaps in debt, and gaps in debt lead in turn to gaps in leverage. The side that holds more raises bigger debt against bigger collateral, and with that debt seizes bigger assets again. This is not any one lawmaker’s choice but the product of a structure in which collateral, loans, and asset prices turn together. You cannot say a 1st-quintile lawmaker with little debt is more frugal, nor that a 5th-quintile lawmaker with large debt overreached. They simply start from different lines on the same rules.
Why bother splitting even debt into quintiles? Look only at the total of positive assets and you learn who is rich, but not how that wealth grew. Only by standing debt next to assets does the operating principle — ‘leverage’ — come into view. The ₩1.26 billion of the 5th quintile is not a signal of crisis but the largest prop holding up the largest assets. Debt was not the shadow of poverty but the shadow of wealth — a structure in which the better-off borrow more and roll over more.
