Asian Stock Markets Volatile: AI Cost Pressure and the Iran-U.S. Ceasefire Deal

Introduction

Asian stock markets swung sharply on Monday as investors weighed AI-driven growth against rising cost pressures, while closely watching the fragile ceasefire deal between the U.S. and Iran. Oil prices remained elevated, while the dollar hovered near a one-year high.

Asian Market Overview

The MSCI Asia Emerging Markets Index (.MIMS00000PUS) was near a two-week low, while the index tracking ASEAN stock markets (.MISU00000PUS) rose 0.4% after touching a two-week low in the previous session.

The divergent market moves reflect investors' caution toward the AI-led stock rebound, especially in South Korea and Taiwan, amid concerns that rising costs could hurt the sector.

Impact of AI Cost Pressure

South Korea's KOSPI index fell as much as 3.4% in early Monday trading before recovering to be down about 2%, after dropping 7% in the previous week. Taiwan's weighted index (TWSE:TAIEX) rose 2.1%; the benchmark is up 56% year to date, making it the second-best performer in the region, behind South Korea's 97% gain.

"The market's focus right now is on AI's return on investment and whether cost pressure is starting to move through the supply chain," said Kyle Rodda, senior financial markets analyst at Capital.com. "Apple's recent announcement … shows that cost pressure from the raw materials needed to build AI will directly affect consumers."

Other Regional Markets

Thailand's SET index rose more than 1%, while Malaysia's stock market (BURSA) fell 0.5% and the Jakarta Composite Index (COMPOSITE) fell 0.4%, putting it on track for its worst June since 2015. The index has now declined for a sixth straight month, with this month's estimated loss at about 4.5%.

Iran-U.S. Ceasefire Deal

The U.S. and Iran agreed to stop retaliatory attacks after both sides launched a new round of strikes over the weekend, and they will hold talks in Doha on Tuesday. The move helped ease tensions in the Middle East, although the ceasefire remains highly fragile.

Currency Market and Supporting Factors

The dollar index (DXY) held steady around 101.4, supported by geopolitical uncertainty and expectations that the Federal Reserve (Fed) will raise rates this year.

"In Asian emerging markets, regional currencies were broadly stable because oil prices did not keep rising, easing pressure on net energy importers such as India, Thailand and the Philippines," said Lukman Leong, an analyst at Doo Financial Futures. "The relatively muted market reaction also reflects expectations that the Middle East conflict will remain contained, allowing investors to refocus on domestic fundamentals."

Asian Currency Moves

The Malaysian ringgit (USDMYR) was the best performer, rising more than 0.6% to 4.063, a near two-week high. The Indonesian rupiah (USDIDR) strengthened to 17,860.

The Philippine peso (USDPHP) and the Thai baht (USDTHB) were little changed, while the South Korean won (USDKRW) fell 0.6% and the Taiwan dollar (USDTWD) edged down 0.2%.

Analysis and Outlook

Analysts say recent market moves reflect multiple uncertainties, including the risk that AI investment returns may fall short of expectations, cost increases being passed on to consumers, and continued tension in Middle East geopolitical conflicts.

The key factor to watch going forward is progress on the U.S.-Iran ceasefire deal. If negotiations succeed, they could help relieve pressure on oil prices and have a positive impact on regional economies, especially energy importers.

At the same time, the outlook for Fed rate hikes continues to influence capital flows into Asian emerging markets and the direction of regional currencies.

Conclusion

Asian stock markets face multiple challenges, including AI cost pressure, uncertainty over the Middle East ceasefire deal, and a rising U.S. interest-rate trend. Investors need to assess these factors carefully while watching earnings from major technology companies and international political developments that will shape the market's future direction.

Overall, markets are expected to remain volatile in the short term as various risk factors persist, while in the long run, AI investment and the global economic recovery will remain important support factors that investors must watch closely.
