Key Takeaways
- South Korea's KOSPI index surged to an all-time high, climbing past 3,800 points and cementing its position as a top-performing global market, largely fueled by robust demand for semiconductor stocks.
- The Korean Won is experiencing significant depreciation pressures, with Bank of Korea (BOK) Governor Rhee Chang-yong attributing 25% of its decline since late August to U.S. dollar strength, alongside contributions from yen weakness, tariff and trade risks, and South Korean overseas equity flows.
- Tesla's (TSLA) Q3 profits plummeted by 37% to $1.4 billion from $2.2 billion a year earlier, despite achieving record vehicle deliveries of 497,099 units, primarily driven by a rush to claim expiring U.S. federal electric vehicle (EV) tax incentives.
- Taiwan's Central Bank is maintaining a stable monetary policy, with its chief indicating that interest rate hikes are unlikely due to the island's consistent economic growth and mild inflation pressures.
South Korean Markets: KOSPI Soars, Won Under Pressure
The KOSPI index, South Korea's benchmark stock index, has reached an all-time high, surpassing 3,800 points and solidifying its status as the world's best-performing major stock market this year. This remarkable rally has been overwhelmingly driven by a blistering run in chipmakers such as Samsung Electronics Co. ((/stock/005930)) and SK Hynix Inc. ((/stock/000660)), which together accounted for nearly two-thirds of the market's gains since September. Foreign and institutional investors have been net buyers, contributing to the index's ascent.
Despite the stock market's strong performance, the Korean Won is facing considerable depreciation. Bank of Korea (BOK) Governor Rhee Chang-yong highlighted multiple factors contributing to the Won's weakness. He stated that U.S. dollar strength accounts for 25% of the Won's depreciation since late August. Additionally, the recent weakness of the Japanese Yen is also playing a role in the Won's decline. Rhee further emphasized that tariff and trade risks, alongside South Korean overseas equity flows, are significant drivers pressuring the national currency. The Won's value against the dollar has been a point of concern, with the BOK closely monitoring its volatility and pace of movement.
Taiwan's Central Bank Maintains Steady Course
In Taiwan, the Central Bank Chief indicated that interest rate hikes are unlikely in the near future. This stance is attributed to the island's stable economic growth and mild inflation, providing the central bank with room to maintain its current policy. The Central Bank of the Republic of China (Taiwan) has kept its benchmark discount rate at 2.000%, marking a sixth consecutive hold as of September 2025. Taiwan's economy has demonstrated resilience, supported by global demand for its emerging tech products, and inflation pressures have remained subdued, staying below the central bank's 2% target.
Tesla's Q3: Record Sales, Plunging Profits
Tesla (TSLA) reported a paradoxical third quarter, with profits plunging by 37% to $1.4 billion, down from $2.2 billion a year earlier. This marks the fourth consecutive quarter of profit decline for the electric vehicle giant. The drop occurred despite the company achieving record vehicle deliveries of 497,099 units in Q3, a 7.4% increase from the prior year.
The surge in deliveries was largely attributed to a rush by U.S. customers to claim expiring federal EV tax incentives before the September 30, 2025, deadline. This "pull-forward" of demand temporarily boosted sales but could create headwinds for Q4 and beyond, as the effective price of EVs increases by $7,500 for buyers without the incentive. Operating expenses for Tesla (TSLA) also surged by 50% year-over-year, driven by aggressive investments in AI research and development, alongside nearly $240 million in restructuring charges. Gross margins hit 18%, the highest for the year but still down from 25% four years ago, as the company offers discounts to compete with rivals.
