[Deep Dive] Jeonse Price Ratio Hits 6-Year High: Impact on the Housing Market

Rising Jeonse Price Ratio Triggered by Supply Shortages

A recent decline in the supply of new apartments, coupled with a shortage of properties available for lease, has caused the Jeonse price ratio (the ratio of lease prices to purchase prices) to show a distinct upward curve. According to the Korea Real Estate Board's weekly apartment price trend data for the second week of June 2026 (as of June 8), the national apartment Jeonse price index rose by 0.12% compared to the previous week, sustaining a steady strong trend. Amidst a simultaneous rise in both purchase and lease prices, the Jeonse price ratio has hit its highest level in over six years, particularly in outer Seoul areas such as Nowon, Dobong, and Gangbuk, illustrating mounting upward pressure across the broader market.

A Structural Support Line for Housing Prices

This steep rise in the Jeonse price ratio extends beyond simple supply-demand imbalances in the rental market; it acts as a powerful structural support line that defends against housing price declines and ultimately pushes purchase prices upward. A high Jeonse price ratio creates a favorable environment for "gap investment" demand—leveraging the interest-free capital of Jeonse deposits—to re-enter the market. Simultaneously, end-users feeling the financial strain of continuously soaring lease deposits are increasingly shifting toward purchasing homes instead. This chain reaction clearly indicates that the current real estate market is re-entering a traditional cyclical loop where rising Jeonse prices drive up overall housing prices.

Risk Management and Strategic Implications

While an increasing Jeonse price ratio injects short-term liquidity into the market and stimulates buying sentiment, it inherently carries structural risks that cannot be overlooked. Generally, when the Jeonse price ratio exceeds the 80% threshold, the risk of "kkangtong jeonse" (underwater properties) rises sharply. In such scenarios, if purchase prices undergo a correction due to macroeconomic shifts or interest rate hikes, tenants may fail to fully recover their deposits. Therefore, market participants—both investors and end-users—must adopt a strictly data-driven approach rather than blindly following superficial price rallies. Before entering any lease agreement, it is imperative to thoroughly review the specific Jeonse price ratio trends of the targeted area and property, prioritizing the verification of legal safety through certified registries. A conservative, asset-protection-focused approach to risk management is more strongly demanded now than ever.
