Korea's three-year bond yield tops 4% for the first time since November 2023
Korea's three-year treasury yield went above 4% in the same week that opposition lawmakers put Seoul's housing starts at well under 60% of their decade average. The National Assembly spent the day arguing about capital-gains deductions.

What happened
- Three-year Korean treasury bonds yielded 4.014% and the ten-year 4.540%, both new highs for the year.
- Democratic Party Rep. Kim Nam-keun presented data putting Seoul construction starts at 58.01% of a ten-year average of 71,258 units, with non-apartment starts at 32.95%.
- The People Power Party called the 1 billion won cap on capital gains tax deductions and the owner-occupancy overhaul "punitive taxation", pointing to a balloon effect in northern Seoul.
- Prime Minister Han Seong-sook said the government would focus on expanding supply by deploying 300 staff per district and operating one-stop support centers.

Why it matters
- cost Property lending costs follow the curve. The loans that pay for new starts get dearer in the same week the government asks for more of them, and developers and their lenders absorb that before any tax change lands.
- constraint Any supply push now routes through a state developer being cut in two, one corporation for land development and construction, another for housing welfare and asset reserves.
- exposure Korean borrowing costs now turn on a Fed decision the market had priced as high as 90%. A senior financial industry official told Sedaily that a decision far removed from expectations could bring considerable confusion from a crisis of confidence in policy.
- contradiction Nuveen says global income-producing real estate is in genuine recovery, transactions up 24% on the year, while Korea's own benchmarks set year highs.
58.01% of 71,258 is 41,337, so Seoul is roughly 29,900 starts short of the ten-year average [4][1][2]. Non-apartment starts ran at 32.95% of their own average [5]. Both numbers reach the record through Sedaily's AI PRISM briefing, a summary service the paper says was developed with support from the Korea Press Foundation [20].
The capital-gains fight is about housing that already stands. Rep. Park Soo-min of the People Power Party said, "When you press down on high-priced homes, mid- and low-priced homes jump and jeonse (lump-sum deposit lease) and monthly rents soar," and asked whether "a successful minority deserves to be persecuted" [7][8]. Deputy Prime Minister Koo Yun-cheol countered that "the intent is to encourage owner-occupancy" [9].
What pays for the housing that does not exist yet reprices off the curve, and the curve moved on American data. US core consumer prices rose 0.3% month on month in August against a 0.2% forecast, and CME FedWatch put the probability of a quarter-point increase at the FOMC as high as 90% at one point [13][14]. Dubai, Brent and West Texas Intermediate all traded above $100 a barrel [12]. Korea's ten-year at 4.540% sits 42.5 basis points below the US ten-year at 4.965%, and its three-year at 4.014% sits 52.6 basis points below its own ten-year [2][11][3][1][4].
Nuveen, which the briefing calls one of the world's five largest real estate investment managers, expects global prices and interest rates to stay elevated for longer and stresses real assets [17]. Real estate's share of institutional investor portfolios fell to 7% in June from 13% in 2022, a drop of six percentage points, or 46% of the 2022 weight [18][5].
The deduction cap changes who keeps the gain on housing already built. The missing 29,900 units still have to be financed at a three-year yield that has not been this high since 2023 [1][2]. In my view the binding constraint is the money and not the tax code, at something like 60/40, because both Korean benchmarks set year highs in the same session as the supply hearing [1][2]. The competing reading is that Seoul's starts are short on land and permits, in which case administrative throughput moves more units than the coupon does. Starts climbing back toward 71,258 with the three-year still above 4% would show the funding cost was never the constraint [4][1].
What to watch
- Whether the FOMC delivers the quarter-point increase CME FedWatch priced as high as 90%, and where the Korean three-year settles after it.
- Whether the 1 billion won cap on capital-gains deductions survives into a final tax bill in its current form.
- The timetable for splitting Korea Land & Housing Corporation, and which of the two new corporations carries the construction pipeline.
