1. After 10% Plunge in Two Trading Days... Daily Average Forced Liquidation Triples

- Key Summary: After the KOSPI touched 8,000 intraday and then plunged 10% within two trading days, forced liquidation risks materialized against a margin loan balance of 36.5675 trillion won (a record high). This month's forced liquidation amount on commission trading receivables averaged 34.3 billion won daily, far exceeding 26.2 billion won in March, when the U.S.-Iran war shock hit, marking the highest monthly level this year. Meanwhile, analysts say passive ETF (exchange-traded fund) forced liquidations could further amplify market volatility, as they mechanically sell index constituents in basket form. The margin loan share of market capitalization stands at 0.55%, the lowest in five years, prompting some to view it as manageable, but warnings have also been raised that during corrections, a 15% stock price drop could expose a wave of investors to margin call risks.

2. Treasury Stock Cancellations Outpace Disposals... KOSPI Re-rating Expectations Mount

- Key Summary: From March until today, since the passage of the third Commercial Act amendment (February 25), treasury stock cancellation disclosures totaled 154 cases, outpacing disposal disclosures (111 cases) for the first time. Compared with last December's extreme imbalance of 137 disposals against 33 cancellations, corporate behavior has shifted rapidly. Under the amendment, both newly acquired and existing treasury shares must be canceled or disposed of within 18 months, leading the market to expect a "push-through" surge in cancellation disclosures in the second half of this year. Treasury stock cancellation reduces outstanding shares, boosting earnings per share (EPS) and per-share value, and is also viewed positively for blocking the so-called "treasury stock magic" (used to expand friendly stakes or as a tool for corporate mergers).

3. China's CXMT Net Profit Jumps 1,688%... Threatens Korea with Low-Priced DRAM

- Key Summary: Changxin Memory Technologies posted first-quarter revenue of 50.8 billion yuan (about 11.1 trillion won), surging 719% year-on-year, while net profit attributable to the parent company soared 1,688% to 24.762 billion yuan (about 5.4 trillion won). By selling roughly 28 billion yuan worth of DRAM inventory secured during the price downturn at high prices during the surge, both profitability and cash flow improved simultaneously. Changxin Memory has lifted its market share to 7.67% (fourth globally) with commodity DRAM (DDR5) priced 15–20% cheaper than Korean products, while HP and Dell are currently conducting quality testing. Concerns are mounting that if encroachment accelerates in the commodity DRAM market, a key cash cow for Samsung Electronics and SK hynix, Korean firms could face price competition pressure and deteriorating profitability.

4. Moody's: "Korea's Banking Industry Regulation Is Considerably Strong"

- Key Summary: Global credit rating agency Moody's, at the "Korea and Asia-Pacific Banking System Outlook" seminar held at the Conrad Hotel in Yeouido, Seoul on the 19th, assessed Korea's financial system regulation as considerably strong, but said the delayed recovery of regional real estate and commercial real estate centered on mid-to-large commercial buildings will exert downward pressure on the soundness of major banks. Sohn Jung-min, a Moody's analyst, said, "The current market interest rate level partially reflects in advance the effect of one or two future base rate hikes," and pointed out that rising rates could lead to deteriorating soundness among vulnerable borrowers with a time lag. He also analyzed that under the government's stance of expanding productive and inclusive finance, the share of corporate loans with high risk weights in bank loan portfolios is increasing, exerting downward pressure on capital. However, the outlook also presented that actual downward pressure may be limited as banks are expected to actively manage their Common Equity Tier 1 ratio (CET1, a core capital soundness indicator for financial firms).

5. Solar Power Generation Costs to Become as Cheap as Nuclear by 2035

- Key Summary: The Ministry of Climate, Energy and Environment announced the "First Renewable Energy Basic Plan" at the 38th Energy Committee on the 19th, aiming to raise the renewable energy power generation share from the current 10% to 30% by 2035. To cumulatively secure 100 GW of renewable energy capacity by 2030, the government plans to install solar power plants equivalent to 5.6 nuclear reactors annually, and to build large flagship power plants with a total capacity of 12 GW at more than 10 sites including the metropolitan area and Chungcheong. The solar power contract unit price (the price supplied to KEPCO with a margin added to generation costs) will fall from the current 150 won per kilowatt-hour (kWh) to 100 won by 2030 and below 80 won by 2035, approaching the level of nuclear power (70–80 won). The government is also considering designating solar modules, solar cells, and wind power plant nacelles as economic security items to foster renewable energy as a new industry.

6. Record 36 Trillion Won in Margin Debt... Lee Chan-jin: "Must Be Vigilant"

- Key Summary: After the KOSPI touched 8,000 intraday on the 15th of this month and then plunged to 7,271.66 today, the margin loan balance stood at 36.3967 trillion won, surging about 33% (8.976 trillion won) from the start of the year (27.4207 trillion won) and remaining at a record high. As investors who exhausted their credit limits resorted to deposit security-backed loans (secured by stocks and bonds) for "averaging down" pursuit buying, the secured loan balance also rose by nearly 2 trillion won this year to 25.9297 trillion won. Concerns have also been raised that volatility could intensify further when single-stock leveraged ETFs launch on the 27th of this month. Lee Chan-jin, governor of the Financial Supervisory Service, said at the "Second Consumer Risk Response Council" the previous day, "We must be highly vigilant about acts that incite excessive margin debt and leveraged investment by financial firms and capital market disruption activities by some 'fininfluencers.'"
