[Key Issue Briefing]

■ Sharp Shift in Mortgage Rate Structure: The share of fixed-rate loans in new home mortgages at banks plummeted from 60.8% in March to 41.6% in May, a drop of 19.2 percentage points over two months. As fixed-rate mortgage rates have risen for eight consecutive months since last October, widening the gap with variable-rate loans (4.23% per year) to 0.21 percentage points, borrowers are rapidly shifting to variable rates. Analysts say a review of mortgage rate strategies is unavoidable.

■ Concerns Over Won Settling in the 1,530s: The won-dollar exchange rate surged to as high as 1,549.80 won during Thursday's session before reversing sharply to 1,532.00 won, as dollar-selling volume presumed to be from foreign exchange authorities flowed in. The market expects settlement demand at the end of the first half and foreign stock selling to support the lower bound of the exchange rate, while wariness over authorities' intervention near the high will limit the upper bound.

■ KOSPI Volatility at Financial Crisis Levels: The KOSPI plunged 519.09 points (5.81%) on Thursday to close at 8,411.21, with market capitalization evaporating by more than 425 trillion won in a single day. Securities analysts interpret the essence of this plunge as an unwinding of concentrated semiconductor positions rather than a new major shock, pointing to the structural concentration in which Samsung Electronics and SK hynix account for 58.1% of the KOSPI as the key amplifier of volatility.

[News of Interest to Property Investors]

1. Fixed-Rate Share of Bank Mortgages Plunges Nearly 20 Points in Two Months

- Key Summary: In May, the mortgage rate at deposit banks (based on newly extended loans) was 4.32% per year, up 0.01 percentage points from the previous month. The fixed-rate type rose to 4.44% per year for the eighth consecutive month, while the variable-rate type fell to 4.23% per year, widening the gap to 0.21 percentage points. The yield on five-year AAA bank bonds jumped 0.29 percentage points from 3.88% in April to 4.17% in May, driving up fixed rates, while the rise in variable-rate benchmarks such as COFIX was limited. The fixed-rate share of new mortgages plunged 19.2 percentage points over two months to 41.6%, and the explanation is that borrowers must carefully weigh the gains and losses of each rate type when choosing a loan strategy.

2. Won Plunges on Presumed Authorities' Intervention…Closes in Low 1,530s Against Dollar

- Key Summary: The won-dollar exchange rate rose to as high as 1,549.80 won during Thursday's session before closing at 1,532.00 won, as dollar selling presumed to be from authorities coincided with the liquidation of long positions. The Dollar Index (DXY) moved around the 101 level, sustaining downward pressure on the won, while the U.S. core PCE price index for May rose 0.3% from the previous month, staying within market expectations. The market expects volatility to continue in the 1,530-1,550 won range for the time being. The interpretation is that if the high-exchange-rate phase persists, real estate development and construction cost burdens will increase, including higher costs of incorporating overseas assets and rising prices of imported materials.

3. The Boomerang of Semiconductor Concentration and Leverage…Intraday Swing of 9% on Minor Noise

- Key Summary: The KOSPI closed at 8,411.21 on Thursday, down 519.09 points (5.81%) from the previous trading day, triggering a circuit breaker. The number of sidecar activations this year totaled 29, surpassing the 26 during the 2008 financial crisis. Foreign investors net-sold 4.6522 trillion won on the KOSPI that day, bringing this month's cumulative net selling to approximately 36.9583 trillion won. Park Yeon-joo, head of the research center at Mirae Asset Securities (006800), said, "Since there is no change in the semiconductor sector's earnings power, there is no need to view this correction as a fundamental change. Short-term volatility driven by supply and demand factors may persist, so it is necessary to respond by focusing on sectors and stocks with strong fundamentals."

4. Mamdani Gains Momentum as Allies Win…1 Million New York Households See Rent Freeze

- Key Summary: The New York City Rent Guidelines Board (RGB) approved by a vote of 7 to 1 a plan to freeze rents for up to two years for approximately 1 million 'rent-stabilized apartments' in New York City. Rent-stabilized apartments account for about 40% of New York City's total housing supply, with about 2.4 million residents. Kenny Burgos, head of the New York Apartment Association, warned, "Many landlords are facing financial difficulties due to soaring maintenance and repair costs," adding, "This will ultimately lead to harm to tenants." Analysts say that as Mamdani-aligned politicians win successive elections, the possibility is growing that the move to expand rent regulations will spread to other regions.
