Seoul shares fell sharply late Tuesday morning as a sell-off in major chip stocks, driven by concerns over AI-related investments, deepened losses. The KOSPI dropped 136.06 points, or 2.36%, to 5,631.95 at 11:20 a.m., after touching an intraday low of 5,493.24. Samsung Electronics fell 1.03% and SK hynix dropped 2.74%, while Samsung Electro-Mechanics rose 2.48%. The won traded at 1,327.6 per U.S. dollar. In the U.S., tech shares rebounded from their steepest weekly drop since June, with the Nasdaq Composite gaining 1.11%, but investors remain cautious ahead of earnings from Tesla and Meta Platforms and the Nov. 3 U.S. midterm elections.

- South Korea , Japan shares fall as Asian stocks decline in break from US chip rally
The MSCI Asia Pacific Index fell 0.6%, with eight of its 11 subgroups down, breaking from a chip-led Wall Street rally. South Korea's Kospi dropped more than 2% and SK Hynix hit its lowest close since April, while data centre firm Elice plunged as much as 32% in its Seoul debut. Japan's Nikkei 225 futures fell 0.8% and Topix dropped 0.9%, while the Philadelphia Semiconductor Index had gained 1.6% on Monday, snapping an eight-day losing streak. The 10-year US Treasury yield was at 5.14% after rising seven basis points on Monday. China's central bank said its overnight reverse repo rate will replace the seven-day rate as the policy benchmark, while gold slipped 0.2% to about US$4,130 an ounce.
- Micron Stock Rises 4 % as Memory Chipmakers Recover After 15 % Weekly Plunge Tied to China Competition Fears
Micron shares rose more than 4% to $916.29 by 10:27 a.m. ET on Monday, leading a rebound in memory chip stocks after a 14.6% drop last week. The sell-off followed China's ChangXin Memory Technologies (CXMT) unveiling an advanced DRAM design, which raised fears of expanded Chinese supply and lower prices. Samsung Electronics and SK Hynix also fell sharply, triggering a circuit breaker on the Korean market. Some analysts argue the threat is overstated in the near term, given leading makers' advantages in high-bandwidth memory used for AI. Broader selling was also driven by hotter-than-expected U.S. inflation data, and investors will watch Meta Platforms' results this week for AI spending signals.
- Prediction: This Will Be Micron's Stock Price By the End of 2027
Micron's shares have risen 333% over the past 12 months as AI data center clients buy its memory chips, with fourth-quarter revenue up 379% year over year to $54.23 billion and net income up more than 10-fold to $37.7 billion. The company has authorized $35.7 billion in share repurchases, and its forward P/E of 7 compares with an S&P 500 average of 19. The author links the low valuation to a sell-off in South Korea, where the KOSPI has fallen over 40% from its June peak, erasing more than $2 trillion, on fears of rising bond yields and growing competition from China's CXMT. Some South Korean experts forecast a memory chip supply glut by 2029, which the author says could bring years of stagnant performance similar to the period after the dot-com bubble. The author concludes investors shouldn't expect the stock to exceed its current price of $879 by the end of 2027.
- SK hynix launches W2tr financing program to bolster chip suppliers
SK hynix has launched a 2 trillion won ($1.5 billion) financing program with major commercial banks and a state-run trade insurer to help domestic chip suppliers secure cheaper funding. Under the deal, SK hynix and the participating banks will contribute 100 billion won, while the Korea Trade Insurance Corporation will provide guarantees worth up to 20 times that amount, supporting as much as 2 trillion won in financing. The initiative targets small and midsized suppliers of semiconductor materials, parts and equipment, who face high borrowing costs. The company is also building the Trinity Fab, an 870 billion won testing facility at the Yongin cluster where suppliers can validate products under real manufacturing conditions.
- South Korean won strengthens on recovery in semiconductor exports
The won strengthened against the US dollar as export-driven supply of dollars grew, with exporters selling USD, supported by a semiconductor boom. The BoK's average won/USD rate for the first 12 trading days of October 2026 was 1,342.6, the lowest since September 2024, compared with 1,528 in June 2026. Average daily trade surplus in September 2026 was nearly $2.5 billion, far exceeding net foreign stock selling. The BoK raised its base rate to 3% in July and August 2026, and the IMF lifted its 2026 growth forecast for South Korea to 3.3%. Analysts expect the won to trade around 1,300 per dollar by year-end, but warn volatility may persist due to Middle East risks, oil prices and foreign capital outflows from the stock market.
- S . Korea growth momentum to strengthen amid chip boom : Finance minister
Finance Minister Lee Hyoung-il said South Korea's growth is projected at around 3% this year, supported by solid chip exports and higher facility investment, with momentum expected to strengthen over the medium to long term. On the sidelines of the IMF and World Bank Group meetings in Bangkok, he briefed Moody's, Fitch and S&P Global Ratings on government-led growth initiatives, including three megaprojects, the green transition and the Future Fund launching next year. The rating agencies were keen to know how the government will use strong tax revenues from the chip supercycle, and noted stable economic indicators and sound public finances despite population aging and the war in the Middle East. Lee also signed memorandums of understanding with multilateral development banks, including EBRD and CABEI, to enhance cooperation on AI.

- Washington-Kyiv rift leaves Ukraine peace facing a new test
U.S. President Donald Trump has repeatedly criticized Ukrainian President Volodymyr Zelensky while Washington eases some energy sanctions on Russia, deepening public disagreements as the sides seek to restart peace talks before winter. On Oct. 19, Trump again suggested Ukraine send someone else to negotiate, the second time in just over a week, after raising on Oct. 10 the idea that Ukraine needs a new president to reach a deal. He argues Kyiv's strikes on Russian refineries push up global fuel prices, while Zelensky warns that easing sanctions on Russian fuel could reduce Moscow's incentive to end the conflict. The fuel move was announced during a Miami meeting of U.S., Ukrainian and European negotiators on Oct. 9, as energy prices remain high ahead of the U.S. midterm elections on Nov. 3. Some U.S. lawmakers have also opposed easing the sanctions.
- Agricultural firms struggle to secure long - term financing despite preferential credit
Agricultural businesses still struggle to obtain medium- and long-term financing for raw material development and deeper processing, despite banks expanding preferential lending programmes. Experts say agriculture accounts for only around 11 per cent of total outstanding bank credit, with a lack of collateral a major obstacle. The State Bank of Vietnam reported total outstanding credit of VNĐ20.75 quadrillion (US$802 billion) as of September 30, up 11.59 per cent from end-2025, with agriculture and rural development at about 22 per cent of the total. The agriculture credit support programme has been expanded from an initial VNĐ15 trillion to VNĐ185 trillion, with cumulative disbursements of nearly VNĐ238.12 trillion by the end of August. Businesses mostly rely on short-term loans tied to export orders, which do not meet long-term investment needs, while fluctuating interest rates raise costs and make planning less predictable.
- Merz Renews German Reform Pledge as Berlin Seeks Private Investment
German Chancellor Friedrich Merz reaffirmed his administrative and social security reform agenda, including cutting bureaucracy and digitizing public administration, at a Berlin investor reception on Oct. 19. The government is pairing its appeal to investors with the €500 billion Special Fund for Infrastructure and Climate Neutrality and about €30 billion in public money through the Germany Fund, which aims to stimulate over €130 billion in investment. Made for Germany estimates €2.9–4.1 trillion in capital needs across five growth areas through 2035, blaming prolonged underinvestment and high energy and labor costs, corporate taxes and regulation. However, a ZDF poll published Oct. 8 found 59% of respondents thought reforms were heading in the wrong direction, and 80% said the burdens were distributed unfairly. The investor summit on Oct. 20 is expected to bring together about 200 executives and investors.
- High bond yields could more than double drag on US growth in 2027: Goldman Sachs
Goldman Sachs estimates higher interest rates would cut US economic growth by about 0.2 percentage points in 2027 under its baseline scenario. If borrowing costs stay near current levels, the drag would rise to just over 0.5 percentage points, more than double. Goldman expects US growth close to its estimated potential rate of 2.3% in 2027, but warns that higher financing costs could weigh on housing, consumption and business investment. Moody's Analytics chief economist Mark Zandi calls the US economy vulnerable rather than resilient, puts the odds of vulnerabilities pushing it 'completely off the rails' at about one in three, and cites weak hiring and stagnant or declining real wages. Goldman also estimates higher refinancing costs could cut business investment growth by about 0.3 percentage points in 2027 and later years, while AI infrastructure investment has stayed resilient despite flagged risks from rising leverage.
- Brooks Says French Bond Strain Has Reached Eurozone Periphery
Robin J Brooks, writing on Substack on Oct. 19, argues that strain in France's bond market is widening borrowing cost gaps across the eurozone periphery, raising contagion risks for other heavily indebted countries. Spreads of 10-year yields over German yields have risen across the periphery as France's spread climbed, and France's 10-year yield hit its highest level of 2026 on Oct. 19. Brooks expects the ECB may first try to cap yields in peripheral countries, notably Italy, though this is his forecast, not announced policy. He notes the equal-weighted average of 10-year yields in the rest of the G10 rose when French yields jumped, which he sees as evidence the strain reaches beyond the eurozone. He believes markets expect the French government to offer concessions to protesters, which would worsen its budget, and in an earlier outlook he assigned a 30% probability to a French debt crisis by year-end.
- Copper is outshining gold this year. Investors say the rally can survive an AI correction
Copper is becoming more strategic for governments and industries as AI, power-grid investment and defense spending boost demand, investors say. Copper has risen 15.8% year-to-date and more than 30% over the past 12 months, while gold futures have fallen 4.11% year-to-date. Ivanhoe Electric CEO Taylor Melvin said demand from technology and defense is almost inelastic and expects copper to withstand recent tech-stock volatility. The rally is also supported by uncertainty over a possible U.S. tariff on refined copper, which the Commerce Department recommended at 15% from Jan. 1, 2027, though no final decision has been announced. Aberdeen's Iain Pyle noted that a large share of the world's copper is now stored in the U.S. and Chinese inventories look exceptionally low, while still seeing underlying fundamentals as clearly bullish.
