[Key Issue Briefing]
■ Sticky Inflation Concerns: May's consumer price inflation rate hit its highest level in two years and two months, jumping into the 3% range. As the high oil price shock spreads across service prices including airlines and lodging, the Bank of Korea expects the 3%-range inflation to continue for the time being.
■ Corporate Bond Freeze: Net corporate bond issuance this year has plunged to its lowest level in 10 years, sharply contracting the funding market. Credit polarization is intensifying, with trillions of won flowing into top-rated bonds while non-prime companies face a string of unsold offerings.
■ Stock Market Overheating Alert: As the KOSPI hit a record high and approached the 9,000 mark, trading value doubled in two months. While foreign investors continued net selling for 18 consecutive trading days, retail investors single-handedly drove buying, expanding volatility.
[News of Interest to Financial Product Investors]
1. Core Inflation Rises 2.5%, Living Costs Up 3.3%… "Likely to Stay in 3% Range for Now"
- Key Summary: Last month's consumer price inflation rate soared to 3.1%, the highest in two years and two months. Petroleum prices surged 24.2% year-on-year, pushing up overall prices by 0.92 percentage points, and international airfares rose 33.5% on the back of fuel surcharge hikes — the highest increase since the related statistics began. As a result, core inflation, a trend price indicator excluding food and energy, rose 2.5%, the largest increase in two years and three months, and living costs jumped 3.3%, the highest since April 2024 (3.6%), or two years and one month. The Bank of Korea forecast that the inflation rate would remain in the 3% range for the time being as the oil price shock gradually spreads to other sectors.
2. Corporate Bonds Hobbled by High Rates… Net Issuance at 10-Year Low
- Key Summary: Net corporate bond issuance this year shrank to 899.8 billion won, the lowest level since 2016, or in 10 years. Compared with 20.3507 trillion won in the same period last year, the figure plunged to one-25th the level, while the yield on three-year AA- corporate bonds has jumped 94.6 basis points (1bp = 0.01 percentage points) this year. Meanwhile, in demand forecasting, Lotte Shopping (023530) (credit rating AA-) secured 1.085 trillion won in valid orders, while Dongwha Enterprise (BBB+) recorded a complete failure to sell, sharply highlighting the temperature gap between rating tiers. NH Investment & Securities (005940) forecast that the K-shaped credit structure would deepen further, diagnosing that monitoring is needed for the liquidity response of companies rated BBB+ or below.
3. Stock Market Overheating Concerns Grow… Trading Value Doubles in Two Months
- Key Summary: As the KOSPI closed at 8,801.49, hitting a record high, the combined trading value of the Korea Exchange and Nextrade (ATS, alternative trading system) recorded 153.7501 trillion won, more than doubling in two months from April. The KOSPI staged a 430-point roller-coaster session, soaring to 8,933.62 in early trading before being pushed down to 8,503.12 on profit-taking. While foreign investors continued net selling for 18 consecutive trading days since the 7th of last month, retail investors net-bought 6.2939 trillion won, virtually single-handedly supporting the index. The market analyzed that short-term overheating fatigue, psychological pressure at the 9,000 mark, concentration in large-cap semiconductor stocks, and an increase in single-stock leveraged products acted in combination.

4. U.S. Banks' AI Company Loan Commitments at 700 Trillion Won… Bubble Trigger Feared If Rates Rise
- Key Summary: Major U.S. banks' loan commitments to artificial intelligence (AI)-related companies amounted to $450 billion (approximately 683 trillion won), reaching 25% of Tier 1 capital — a loss-absorbing capacity indicator that combines bank capital and retained earnings. Loan commitments to high-risk borrowers with credit ratings of B or below alone reach $50 billion (approximately 75 trillion won), and borrowing scale is growing larger, with Anthropic recently pursuing a $36 billion AI chip purchase loan. The Federal Reserve Bank of Chicago warned that with loan commitments approaching 25% of Tier 1 capital, large-scale losses are feared if risks materialize, and that if non-bank financial institutions are included, the crisis could spread throughout the financial system. Additionally, according to the St. Louis Fed, AI-related investment drove approximately 39% of U.S. GDP growth in the first three quarters of last year.
- Key Summary: Samsung Electronics' (005930) combined common and preferred stock market capitalization recorded $1.56 trillion, pushing aside Meta Platforms ($1.524 trillion) to enter the top 10 in global listed company market cap rankings. With the market cap gap with ninth-place Tesla at just $1 billion, all three memory companies have surpassed $1 trillion in market cap on the back of the full-fledged supply of high-bandwidth memory (HBM), the next-generation AI semiconductor memory. KOSPI market cap also surged 86% this year alone to $5.042 trillion, surpassing the Indian exchange ($4.843 trillion) to leap to sixth in the world. Major domestic securities firms expect Samsung Electronics' operating profit to exceed 500 trillion won next year, and global investment banks are joining the memory market optimism in unison, with UBS raising Micron's target price by 204% from the previous level.
6. ETF Investing: 'Visible Fees' Aren't the Whole Story
- Key Summary: As retirement pension reserves surpassed 500 trillion won and exchange-traded fund (ETF) investment amounts recorded growth rates of over 100% for three consecutive years, ETFs have established themselves as the core investment vehicle for defined contribution (DC) and individual retirement pension (IRP) plans. However, ETF investment costs include not only management fees (averaging 0.3% as of May) but also the bid-ask spread, an implicit transaction cost arising from the difference between buy and sell quotes. According to an analysis by global asset manager Vanguard, European ETF spreads are 0.03–0.1% per trade, about three times that of the U.S., and overall costs increase sharply when trading frequency exceeds four times per year. Additionally, during single-price auction periods from 9:00 to 9:05 a.m. and 3:20 to 3:30 p.m., when liquidity providers (LPs) are exempt from mandatory quote provision, bid-ask spreads can widen abnormally, requiring caution in choosing trading times.
