Jeonse deposits and household debt keep Korean housing anxiety high
Korea's unique jeonse rental system turned housing into the country's dominant financial asset and its households into some of the developed world's most indebted — a structure that converts every swing in property prices into a test of financial stability.

To understand Korean household finance, start with a rental contract that exists almost nowhere else. Under jeonse, a tenant hands the landlord a lump-sum deposit — historically half to four-fifths of the property’s value — lives rent-free for the contract term, and receives the deposit back on leaving. The landlord, in effect, takes an interest-free loan and invests it, often in the next property. For decades the system suited everyone: tenants built forced savings toward ownership, landlords obtained leverage banks would not extend, and housing absorbed the nation’s savings.
The same design hard-wires debt into every layer. Tenants borrow to raise deposits; landlords count liabilities in returnable deposits; owners borrow against price expectations. Add mortgage credit proper and Korean household debt stands just under 1,900 trillion won by Bank of Korea tallies from the mid-2020s — relative to GDP, persistently among the highest in major economies, hovering near the size of annual output. The Bank of Korea has for years named household leverage as the economy’s chief internal vulnerability, and its interest-rate decisions are read domestically as much for their housing effect as their inflation effect.
The system’s fragility showed plainly in the jeonse fraud wave of 2022 and 2023. When prices and deposits fell after the pandemic-era boom, thousands of tenants — disproportionately young people in lower-priced multiplex housing — discovered that leveraged landlords could not or would not return deposits, in schemes ranging from overextension to outright organised fraud. The episodes, which drew national attention through cases involving hundreds of properties under single owners, prompted expanded deposit-guarantee insurance, priority-repayment protections and criminal prosecutions, and pushed part of a generation of renters toward monthly rent, long the stigmatised option.
That shift is one strand of a slow structural migration. High interest rates make jeonse’s interest-free deposit costly for landlords to accept and risky for tenants to place, so contracts have drifted toward hybrid forms — smaller deposits plus monthly payments. Each step of that migration surfaces a cost the old system had hidden: housing that must be paid for out of income, in cities where income has not been priced for it.
Underneath sits the concentration problem. Korean household wealth is held overwhelmingly in real estate, and within that, in capital-region apartments — the asset young households feel they must buy before prices escape them, using the leverage that then defines their finances for decades. Governments of both parties have alternated between suppressing that demand with tax and loan limits and stimulating it to support the market, more than twenty major policy packages in a decade, without changing the underlying belief that the apartment is the only reliable store of value.
For outside observers, Korea offers a controlled experiment in what happens when a society finances housing through private leverage layered on private leverage. It functions — often impressively — while prices rise and rates stay low, and it transmits stress with unusual speed when either condition breaks. Anxiety, in that structure, is not a mood. It is the system’s operating temperature.
