Jeonse Market Recovery: Post-Crisis Rental System Stabilization Assessment

Intelligence Brief | 2030 Seoul Plan Monitoring Series | March 2026

Executive Summary

Korea’s jeonse rental system, a globally unique arrangement in which tenants deposit a lump sum (typically 50-80% of the property’s market value) with the landlord in lieu of monthly rent, experienced a systemic crisis in 2022-2023 that threatened the financial security of millions of Korean households. The crisis, triggered by falling property prices that eroded landlords’ ability to return deposits, exposed fundamental structural vulnerabilities in a system that functions as an unregulated shadow banking mechanism. As of Q1 2026, the jeonse market has stabilized but is undergoing irreversible structural transformation. Jeonse’s share of total rental contracts in Seoul has fallen from 67% in 2019 to 48% in 2025, with monthly rent (wolse) absorbing the remainder. Government interventions, including the expanded Housing Deposit Protection Fund and mandatory deposit insurance, have addressed the immediate crisis but have not resolved the underlying systemic risks. This brief examines the crisis, the recovery, the structural shift, and the implications for the 2030 Seoul Plan’s housing policy framework.

The Jeonse System: Structure and Scale

Jeonse is a rental arrangement without close parallel in other national housing systems. Under a jeonse contract, the tenant provides the landlord with a large lump-sum deposit (jeonse-geum), typically ranging from 50% to 80% of the property’s market value. The landlord invests this deposit, traditionally in real estate (often purchasing additional properties), and returns it at the end of the lease term (typically two years). The tenant pays no monthly rent, effectively “lending” the landlord capital in exchange for housing.

The system evolved during Korea’s rapid urbanization period (1960s-1990s) when formal mortgage markets were underdeveloped and landlords needed capital to acquire additional properties. The jeonse deposit effectively functioned as a zero-interest loan from tenant to landlord, secured by the property itself. As long as property prices rose continuously, the system was self-sustaining: landlords could return deposits by collecting new, larger deposits from incoming tenants or by selling appreciated properties.

The 2022-2023 Crisis: Anatomy and Impact

The crisis was precipitated by the Bank of Korea’s interest rate tightening cycle, which raised the base rate from 0.50% in May 2021 to 3.50% by January 2023. Rising interest rates depressed property prices (Seoul apartments fell approximately 8% from peak to trough) and simultaneously increased the financing costs for landlords who had borrowed against their properties. The result was a wave of “jeonse fraud” cases and deposit non-return incidents that became a national crisis.

The “Gap Investment” Vulnerability

The core systemic risk was concentrated in “gap investment” (gap tuza) landlords, property owners who purchased multiple apartments using stacked jeonse deposits with minimal personal equity. The business model works as follows: an investor purchases a KRW 1 billion apartment by taking a jeonse deposit of KRW 700 million (70% jeonse-to-sale ratio) and providing KRW 300 million in personal equity (or borrowing it). If property prices rise 10%, the investor’s equity grows from KRW 300 million to KRW 400 million, a 33% return. If the investor acquires 5 properties using this method, each with KRW 300 million equity, total exposure is KRW 5 billion with KRW 1.5 billion personal equity, leveraged 3.3x through jeonse deposits.

When property prices fell 8% in 2022-2023, these leveraged landlords faced equity erosion that, in many cases, rendered them unable to return jeonse deposits. The mathematics were devastating.

Approximately 220,000 gap investment landlords were operating in Seoul at the peak in 2021. The Korea Housing Finance Corporation estimated that 38,000 of these (17.3%) entered negative equity positions during the price decline, meaning their combined mortgage debt and jeonse obligations exceeded their property values.

Human Impact

The crisis directly affected tenants who could not recover their deposits. The National Police Agency reported 4,200 jeonse fraud cases in 2023, up from 1,100 in 2021. The most notorious case involved a single landlord in Incheon who accumulated 1,100 properties using stacked jeonse deposits totaling KRW 130 billion, defrauding approximately 2,400 tenants. Several tenant suicides were publicly linked to jeonse deposit losses, generating intense media coverage and political pressure for reform.

Government Response and Reform Package

The national government and Seoul Metropolitan Government deployed a multi-pronged intervention package beginning in mid-2022 and expanded through 2024.

Housing Deposit Protection Fund

The Housing Deposit Protection Fund (jeonse bogeum geum), operated by the Korea Housing and Urban Guarantee Corporation (HUG), was expanded from its pre-crisis capacity of KRW 12 trillion to KRW 50 trillion. The fund guarantees jeonse deposit returns for tenants whose landlords default, functioning as a backstop similar to deposit insurance in the banking system.

The fund’s expanded capacity has provided essential crisis containment. However, the gap between active guarantees (KRW 145 trillion) and fund capacity (KRW 50 trillion) represents a systemic risk: if default rates were to reach 35% simultaneously, the fund would be exhausted. The implicit government guarantee behind the fund means that ultimate losses would be socialized through public finance, creating a moral hazard dynamic similar to those observed in banking systems with explicit deposit insurance.

Mandatory Deposit Insurance

Legislation enacted in July 2024 requires mandatory jeonse deposit insurance for all new contracts with deposits exceeding KRW 150 million (covering approximately 72% of Seoul jeonse contracts by value). The insurance premium, currently set at 0.128-0.154% of the deposit amount annually, is split equally between landlord and tenant. Coverage provides 100% deposit return guarantee in case of landlord default.

The mandatory insurance system addresses the moral hazard problem by pricing risk: landlords with multiple properties and high leverage pay higher premiums, creating a financial incentive to reduce gap investment behavior. However, implementation challenges remain. Approximately 22% of eligible contracts have not enrolled in the mandatory system as of Q1 2026, with enforcement mechanisms still being established.

Revised Housing Lease Protection Act

The 2024 revision to the Housing Lease Protection Act strengthened tenant protections in several dimensions.

Structural Transformation: Jeonse to Wolse

The most significant long-term consequence of the crisis is the accelerated transition from jeonse to monthly rent (wolse). This shift, already underway before the crisis due to low interest rates (which reduced landlords’ returns on jeonse deposits), has been dramatically accelerated by the crisis experience.

The transition has profound distributional consequences. Under the jeonse system, tenants with accumulated savings or family support could avoid monthly housing cost outflows entirely, preserving cash flow for other consumption and savings. The shift to wolse increases monthly housing costs for these households while simultaneously lowering the upfront capital barrier for asset-poor but income-adequate households.

Market Recovery Assessment (Q1 2026)

The jeonse market has stabilized from its crisis nadir but has not returned to pre-crisis conditions. Key recovery indicators show mixed signals.

Deposit levels. The average Seoul apartment jeonse deposit has recovered to KRW 498 million from the crisis trough of KRW 475 million (2023) but remains below the 2021 peak of KRW 510 million. The jeonse-to-sale price ratio has fallen from 72% (crisis peak, when sale prices dropped faster than jeonse deposits adjusted) to 65%, approaching the historical norm of 60-65%.

Transaction volume. Jeonse contract registrations in Seoul are running at approximately 48,000 per month, down from the pre-crisis average of 57,000 (2019) but up from the crisis low of 38,000 (mid-2023). The decline reflects both the structural shift to wolse and lingering risk aversion among tenants who now prefer the transparency of monthly rent.

Fraud incidence. Reported jeonse fraud cases have declined to 1,400 in 2025 from the peak of 4,200 in 2023, reflecting both improved screening through the mandatory HUG registry check and reduced gap investment activity due to heightened regulatory scrutiny.

Landlord behavior. The number of gap investment landlords has declined from 220,000 (2021 peak) to an estimated 165,000. New acquisitions using the gap investment model have slowed dramatically as banks tightened lending standards and mandatory deposit insurance increased the cost of leveraged property accumulation.

Fiscal Impact

The jeonse crisis and subsequent reforms have imposed significant fiscal costs on both national and metropolitan government.

The KRW 13.9 trillion cumulative cost represents approximately 0.6% of national GDP over the four-year period. HUG’s claims payments account for the majority, reflecting the fund’s role as the primary deposit return guarantor. These costs are partially recoverable through HUG’s subrogation rights against defaulting landlords, but historical recovery rates for jeonse-related claims have been approximately 35-40%, suggesting that KRW 8-9 trillion will ultimately be absorbed by public finance.

Implications for the 2030 Seoul Plan

The jeonse market transformation intersects with multiple 2030 Seoul Plan dimensions.

Housing affordability. The shift from jeonse to wolse changes the affordability calculus. Under jeonse, affordability was primarily a wealth/savings constraint (do you have KRW 400-500 million for a deposit?). Under wolse, affordability becomes primarily an income constraint (can you afford KRW 100-120 million per month in rent?). Policy instruments must adjust accordingly, shifting from deposit support programs to income-based rental subsidies.

Public housing demand. The erosion of jeonse as a “free rental” mechanism for asset-holders is driving increased demand for public rental housing. SH Corporation’s public rental waiting list has grown by 42% since 2022, reflecting households that previously relied on jeonse but now seek the security and affordability of public options.

Financial system stability. The jeonse system represents an unregulated pool of approximately KRW 288 trillion in outstanding deposits. The mandatory insurance system is gradually bringing this pool under regulatory oversight, but coverage remains incomplete. A second price decline of similar magnitude to 2022-2023, before insurance coverage reaches critical mass, would regenerate crisis conditions.

Demographic implications. The jeonse system historically facilitated household formation by providing relatively low-cost housing to young couples accumulating savings for property purchase. Its erosion may contribute to delayed household formation and lower fertility, compounding the population emergency dynamics described elsewhere in this series.

Risk Assessment

Systemic risk (medium). Another significant property price decline (exceeding 10%) before the mandatory insurance system reaches full coverage could trigger a renewed deposit crisis. Probability assessed at 15-20% within the 2026-2028 window.

Transition risk (high). The jeonse-to-wolse transition will produce distributional winners and losers. Households reliant on the jeonse system, particularly elderly asset-holders and families using jeonse as a wealth preservation mechanism, face material deterioration in their housing situations. Political pressure from these constituencies may lead to policy interventions that delay the transition without resolving underlying risks.

Moral hazard (medium). The expanded deposit guarantee system may encourage continued risk-taking by both landlords (who know deposits will be guaranteed) and tenants (who may not adequately scrutinize landlord financial health). Addressing this requires risk-based pricing and effective enforcement, both of which remain works in progress.

Recommendation

The jeonse market recovery should be viewed not as a return to the pre-crisis status quo but as a managed transition toward a more transparent, better-regulated, and ultimately more sustainable rental market structure. Priority actions include: completing the mandatory deposit insurance rollout to achieve 90%+ coverage by 2028, expanding income-based rental subsidies to offset the affordability impact of the jeonse-to-wolse transition, accelerating public housing delivery to absorb demand from households exiting the jeonse system, and developing financial literacy programs to help households navigate the changing rental landscape. The 2030 Seoul Plan’s housing policy framework should be updated to reflect the structural transformation of the rental market and its implications for affordability, demand patterns, and public housing requirements.
