■ BOK Shifts to Tightening: Yoo Sang-dae, Deputy Governor of the Bank of Korea, officially formalized the rate hike stance, making signals of a monetary policy shift visible in the market. The market expects the base rate to reach the 3% level with an initial hike in July followed by one additional hike within the year.
■ Polarized Chip-Driven Market: The KOSPI surged more than 5% to break through the 6,900 mark, but declining stocks (476) outnumbered advancing stocks (392), keeping the warmth limited. The combined market capitalization of Samsung Electronics (005930.KS) and SK hynix (000660.KS) accounted for 42.2% of the entire KOSPI, marking the highest concentration on record.
■ Growing Burden on Vulnerable Borrowers: With the delinquency rate for small and medium-sized enterprises and self-employed borrowers at the four major banks rising to 0.53%, a 0.25 percentage point hike in the base rate is estimated to increase interest burdens for the self-employed by 1.8 trillion won. If the scenario of two rate hikes within the year materializes, interest burdens are expected to increase by 3.5 trillion won this year alone.

1. BOK Shifts to Tightening Amid 3% Inflation Threat… “May Raise Rates Twice Within the Year”
– Key Summary: Yoo Sang-dae, Deputy Governor of the Bank of Korea, officially formalized the rate hike stance in a public venue, stating that domestic prices are under considerable upward pressure due to the fallout from the Middle East war. JP Morgan raised its domestic inflation forecast for this year from 1.7% to 2.7%, while Bank of America Merrill Lynch also lifted its forecast from 2.1% to 2.9%. Experts project that following a base rate hike in July, an additional hike in October or November will bring the base rate to around the 3% level within the year. Meanwhile, with growth rate forecasts for this year being successively raised due to the semiconductor super cycle and strong domestic demand driven by supplementary budget execution, the likelihood of a sharp contraction in the real economy despite rate hikes remains low.
2. More Stocks Fell Than Rose… Samsung Electronics and SK hynix Market Cap Concentration Deepens
– Key Summary: The KOSPI closed at 6,936.99, up 338.12 points (5.12%), as foreign investors net purchased 3.0184 trillion won and institutions also net bought 1.9353 trillion won, lifting the index through dual-track buying. The combined market capitalization of Samsung Electronics and SK hynix reached 42.2% of the entire KOSPI, the highest proportion on record, while SK hynix surpassed 1,000 trillion won in market cap at 1,031.2803 trillion won, becoming the second company after Samsung Electronics to break the 1,000 trillion won mark. Meanwhile, 392 stocks on the KOSPI advanced while 476 declined, limiting the overall market sentiment despite the index’s sharp rise. By sector, information technology (17.62%), securities (10.06%), and electrical and electronics (7.70%) showed strength, while construction (-3.99%) and leisure and culture (-1.38%) declined, making the polarization clear.
3. Short Selling and Margin Debt Rise Together… Stock Market Overheating Signals at Peak
– Key Summary: The net short selling balance in the KOSPI market increased 38.4% in one month to 20.3887 trillion won, surpassing 20 trillion won for the first time in history. In addition, the margin loan balance also reached 35.7131 trillion won, setting a new record high in the 36 trillion won range and continuing its upward trajectory. Investor deposits, which are standby funds for the stock market, recorded 124.7591 trillion won, remaining above 120 trillion won for 10 consecutive trading days. The KOSPI 200 Volatility Index (VKOSPI), known as the “Korean fear index,” recorded 55.87, showing heightened concerns about expanding volatility as two-way bets on both market declines and rises surge simultaneously.

4. Money Floods into Bond-Mixed ETFs Holding Samsung Electronics and SK hynix
– Key Summary: Among domestically listed ETFs (exchange-traded funds) last month, the product with the largest inflow was the ‘RISE Samsung Electronics SK hynix Bond Mixed 50,’ which attracted 655.5 billion won. The product has a bond-mixed structure incorporating Samsung Electronics and SK hynix at 25% each, with government bonds and monetary stabilization bonds at 50%. While classified as a safe asset in retirement pension accounts, it can expand the effective stock weighting to up to 85%. Demand appears to have concentrated on maximizing semiconductor exposure by utilizing the 70% risk asset limit regulation on pension accounts. Meanwhile, three of the 17 ETFs newly listed on the KOSPI market last month had the same bond-mixed structure, showing that competition among asset management companies to preempt the market is fully underway.
5. U.S. DRAM ETF Surges 45% in One Month… Korean Overseas Retail Investors Bought 10%
– Key Summary: The ‘Roundhill Memory ETF (ticker DRAM),’ which listed on the New York Stock Exchange on the 2nd of last month, recorded a return of 45.57% within one month of listing, overwhelming Korea’s representative semiconductor ETFs ‘TIGER Semiconductor TOP10’ (36.87%) and ‘KODEX Semiconductor’ (40.04%). Of the assets under management (AUM) of $2.48 billion (approximately 3.65 trillion won), Korean overseas retail investors (domestic investors investing in foreign stocks) net purchased $225.57 million (approximately 332 billion won), accounting for 9.8% of inflows. The ETF has a world-first structure that focuses exclusively on global memory semiconductors with SK hynix (25.94%) and Samsung Electronics (21.62%) as its core pillars. The widening return gap is analyzed as the memory market rally, led by high-bandwidth memory (HBM), spread to NAND flash, with related stocks staging a rally.
6. SME Delinquency Rates Soaring… Rate Hikes Would Directly Hit Vulnerable Borrowers
– Key Summary: The delinquency balance for SMEs and self-employed borrowers at the four major banks (KB Kookmin, Shinhan, Hana, Woori) stood at 3.015 trillion won as of the end of March this year, an increase of 486 billion won from the end of December last year, with the delinquency rate also rising from 0.45% to 0.53%. The SME loan delinquency rate at four regional banks (Busan, Kyongnam, Gwangju, Jeonbuk) surged 0.39 percentage points from 1.07% to 1.46% in one year, highlighting the deteriorating soundness of regional finance. The average interest rate on new mortgage loans from deposit banks in March this year rose to 4.34%, marking the sixth consecutive month of increase, while the average card loan rate from credit card companies also rose to 13.76%. The Bank of Korea estimates that a 0.25 percentage point hike in the base rate would increase interest burdens by 1.8 trillion won for the self-employed and 3 trillion won for households, raising concerns about vulnerable borrowers.
