The South Korean central government has re-imposed a "triple regulation" on Dongtan, Giheung, and Guri to combat soaring house prices [1].

These measures target the "balloon effect," where buyers migrate to non-regulated areas to avoid strict lending and tax rules in primary hubs. By designating these three areas as adjustment target areas, speculative overheating zones, and land-transaction permit zones simultaneously, the government seeks to stabilize a volatile market.

The new regulations take effect July 1, 2026 [1]. The specific component regarding land-transaction permit zones will begin on July 5, 2026 [1].

This move follows a period of instability after the government implemented housing-market measures on Oct. 15, 2025 [1]. Those previous measures designated Seoul and 12 major areas in Gyeonggi Province as regulated zones [1]. Eight months after those policies, demand shifted toward neighboring regions that lacked such restrictions [1].

Economic factors in the tech sector further intensified the pressure. High performance bonuses paid to employees at Samsung Electronics and SK Hynix due to a semiconductor boom triggered a surge in demand [1].

"As loan and tax thresholds rose in core areas and investment for profit became impossible, buying pressure flowed to adjacent non-regulated areas as feared," said YTN reporter Cha Yu-jeong [1].

Cha Yu-jeong said the high performance bonuses from semiconductor giants were a decisive factor in the explosion of demand that led the government to bind Hwaseong's Dongtan, Guri, and Yongin's Giheung district with triple regulations [1].

The government's decision highlights the difficulty of controlling real estate prices in a high-growth tech corridor. When regulations are applied only to primary hubs, capital often flows into nearby satellite cities, creating localized bubbles. By linking the current price surge to semiconductor industry bonuses, the government acknowledges that corporate wealth in the tech sector is directly influencing residential real estate volatility in Gyeonggi Province.
