Asian markets closed higher on Tuesday, powered by a fresh wave of enthusiasm for artificial intelligence that sent chip stocks in South Korea and Taiwan surging. The rally pushed MSCI's broad emerging-Asia index to its highest level since June 30, a sign that investors are betting on continued growth in the semiconductor sector.
But the day's gains were not universal. In the Philippines, the peso weakened to a record low against the U.S. dollar, weighed down by persistently high oil prices and a broadly stronger dollar. The contrasting moves highlight how a single global trend—AI-driven demand for chips—can lift some economies while leaving others exposed to different pressures.
What drove the rally?
The gains were led by the region's biggest chipmakers. South Korea's KOSPI index jumped 4.6%, with memory-chip giant SK Hynix climbing 8.3% and Samsung Electronics adding 5.7%. In Taiwan, the benchmark index rose 1.7%, with contract chipmaker TSMC gaining 2.1%.
These companies are at the heart of the global AI boom. They produce the advanced semiconductors used in data centers, cloud computing, and AI models, and investors have been pouring money into them on expectations that demand will stay strong for years. The AI chip rally has been a recurring theme in Asian markets, and Tuesday's move was the latest example.
Because South Korea and Taiwan account for a large share of the MSCI EM Asia index—which weights countries by their total market size—their gains lifted the entire gauge by as much as 2.1%. For investors holding broad emerging-market funds, that means the performance of a few big tech names can have an outsized impact on their returns.
Why the peso is under pressure
While chip stocks soared, the Philippine peso took a hit. The currency fell to a record low against the dollar, a move driven by two main factors: oil prices that remain elevated and a dollar that has been strengthening globally.
The Philippines is a net importer of oil, so when crude prices stay high, the country's import bill rises, putting pressure on its currency. At the same time, a stronger dollar makes it more expensive for emerging-market currencies to hold their value. This is a familiar squeeze for countries that rely on imported energy and have external debt.
For ordinary Filipinos, a weaker peso can mean higher prices for imported goods, including fuel and food, which can feed into inflation. For investors, it raises the risk of currency losses when holding Philippine assets, even if local stocks or bonds perform well.
What it means for investors
The divergence between the chip rally and the peso's slide is a reminder that emerging markets are not a monolith. While some countries benefit from global tech trends, others are more exposed to commodity prices and currency swings.
For investors with exposure to Asian equities, the rally in chip stocks is a positive sign, but it also concentrates risk. If AI enthusiasm fades or chip demand slows, the same stocks that drove gains could drag the index down just as quickly. Diversification across sectors and countries remains a key consideration.
On the currency side, the peso's weakness highlights the importance of monitoring oil prices and the dollar's trajectory. Oil staying near $97 has been a persistent theme, and any further spike could add to pressure on import-dependent economies like the Philippines.
Investors should also keep an eye on U.S. monetary policy. A stronger dollar often reflects expectations of higher U.S. interest rates, which can pull capital away from emerging markets. Fed rate hike bets have been climbing, and that trend could weigh on Asian currencies beyond the peso.
Looking ahead
For now, the AI trade remains the dominant force in Asian markets. South Korea and Taiwan are likely to stay in focus as long as demand for chips continues to grow. But the peso's record low is a cautionary tale: not every market moves in the same direction, and global forces like oil and the dollar can quickly change the picture.
As always, investors should consider their own risk tolerance and time horizon. The key is to understand what drives each market and to avoid assuming that a rally in one part of Asia will lift all boats.
