[Key Issue Briefing]

■ Momentum for Northern District Development: The Seoul Metropolitan Government will halve the public contribution ratio for pre-negotiation target sites in the northern and southwestern districts and raise the residential ratio ceiling to as much as 90%. As a result, large-scale idle site development in underdeveloped areas—which have failed to secure business viability for decades due to insufficient demand for commercial and business facilities—is expected to gain full momentum. Large projects that had been stalled in the northeastern and southwestern districts, including the former National Institute of Health site (48,000 square meters) in Eunpyeong-gu appraised at 454.5 billion won, are showing increased potential for private-sector participation following this system overhaul.

■ Collapse of the Housing Ladder: According to the OECD's '2026 Korea Economic Report,' the proportion of housing that median-income households in Seoul can purchase using mortgage loans plunged 25 percentage points from 32% in 2012 to 7% in 2025. The OECD identified the main cause as the near-doubling of apartment transaction prices in the Seoul metropolitan area between 2013 and 2026, far outpacing wage growth. It also pointed out that chronic supply shortages are deepening the housing burden, with Seoul's housing supply ratio in 2024 falling below 94 units per 100 households.

■ Tax Expenditure Warning: The income deduction reduction for credit card spending reached 4.6298 trillion won this year and is on the verge of surpassing 5 trillion won next year. Temporarily introduced in 1999 and extended 11 times to effectively become a permanent program, this deduction is raising warnings about fiscal soundness amid a trend in which total tax expenditures more than doubled from 37.4 trillion won in 2016 to 80.5 trillion won this year.

[News of Interest to Property Investors]

1. Residential Ratio Also Raised to 90%... Development Momentum for Long-Neglected Eunpyeong National Institute of Health Site

- Key Summary: The Seoul Metropolitan Government revised its guidelines to halve the public contribution ratio for pre-negotiation target sites in the northern and southwestern districts and raise the residential ratio ceiling to as much as 90%. A direct beneficiary of this measure is the former National Institute of Health site (48,000 square meters) in Nokbeon-dong, Eunpyeong-gu, appraised at 454.5 billion won. The site failed to sell in its first sale notice in April last year, as no companies submitted bids, but the likelihood of a successful sale is expected to increase as the residential ratio ceiling rises to 60-70% and the public contribution ratio decreases. Analysts say the site, capable of supplying at least 4,000 units, could create large-scale residential supply capacity within central Seoul. Meanwhile, pre-negotiations to build a mixed-use residential complex of about 510 units up to 49 stories high began this January at the former Nowon Driving School site (12,266 square meters) in Junggye-dong, Nowon-gu, and this is expected to serve as a test case for securing business viability through residential-focused development.

2. Housing Affordable for Middle-Class in Seoul Drops from 32% to 7% in 13 Years

- Key Summary: According to the OECD's '2026 Korea Economic Report,' the proportion of housing that median-income households in Seoul can purchase using their own capital and standard mortgage loans stood at about 7% as of 2025, a plunge of 25 percentage points from 32% in 2012. The OECD applied a purchasability standard of mortgage repayments not exceeding 25% of household income, and analyzed that the impact came from apartment transaction prices in the Seoul metropolitan area nearly doubling between 2013 and 2026, far outpacing wage growth. Seoul's housing supply ratio in 2024 was below 94 units per 100 households, falling short of the national average (102.5 units). The OECD recommended that Korea's housing policy move away from simple supply expansion, strengthen accessibility standards for jobs and daily services, and shift toward a public rental model reflecting regional demand.

3. '30-Year Patchwork' Card Income Deduction Nears 5 Trillion Won... Fiscal Cliff if Left Unchanged

- Key Summary: The income deduction reduction for credit card spending reached 4.6298 trillion won this year, growing 46.2% over the past four years, and is likely to surpass 5 trillion won next year. Temporarily introduced in September 1999 to bring transactions into the tax base, the program has since been extended 11 times, effectively becoming a permanent fixture, and expanded into a structure allowing deductions of up to 4 million won as traditional markets, public transportation, and book and performance expenses were successively added to the deduction targets. Kim Woo-cheol, a professor of taxation at the University of Seoul, explained, "Income deductions are structured to favor those with high marginal tax rates," adding that lower-income groups may not receive benefits because they pay little tax. Experts advise that, given the total tax expenditure scale that more than doubled from 37.4 trillion won in 2016 to 80.5 trillion won this year, deduction sizes should be reduced sequentially, starting with outdated programs.

4. U.S. Households Reel from Grocery and Gas Prices... Suhyup Bank Says "Living Cost Burden at Critical Point"

- Key Summary: In its June 'House View' report released Tuesday, the Risk Management Group of Sh Suhyup Bank diagnosed that its in-house U.S. household burden indicator, the HASI (Household Affordability Stress Index), had re-entered the critical zone (above 35). HASI combines the 30-year fixed mortgage rate with the EPI (Everyday Pressure Index), which is composed of prices for daily necessities such as gasoline, beef, milk, and eggs, and calculates in minutes the working hours a worker needs to cover major living necessities. Following U.S. and Israeli military airstrikes on Iran, gasoline prices soared nearly 55% in two months, from $2.91 per gallon in February this year to $4.50 in May, driving the rise in HASI. Suhyup Bank viewed a decline in gasoline prices from stabilization in the Middle East and signals of additional rate cuts by the U.S. Federal Reserve as the key variables that will determine the future course of U.S. domestic consumption.
