Asia stocks slip on growing Fed hike bets, fresh Middle East tensions

Asian stock markets experienced a decline on Monday due to heightened investor caution following remarks from Federal Reserve Chair Kevin Warsh and ongoing tensions in the Middle East. Warsh's hawkish comments at the Jackson Hole symposium reignited speculation of a potential U.S. interest-rate increase, prompting markets to adjust their expectations.

Concurrently, heightened concerns over Middle Eastern conflicts contributed to a rise in oil prices, which further fueled inflation worries and added to the bearish sentiment.

The performance of Asian stock indices mirrored the broader market concerns. South Korea's KOSPI fell by 1.5%, with significant losses for chip manufacturers such as Samsung and SK Hynix. Japan's Nikkei 225 and TOPIX index both experienced a 1.1% and 0.5% drop, respectively, as investors closely monitored the yen's exchange rate against the U.S. dollar, which briefly exceeded 160 yen.

The escalation in U.S.-Iranian hostilities heightened the pressure on oil markets, with Brent crude prices breaching the $90 per barrel mark following U.S. strikes on Iranian targets in the region. In response, Iran reportedly retaliated by attacking U.S. forces in Jordan.

China's Shanghai Composite index saw a slight decline of 0.2%, while the Shanghai Shenzhen CSI 300 index dropped by 0.8%. Hong Kong's Hang Seng index also experienced a decline of 0.8%. Investors analyzed regional economic indicators to gauge the impact on market sentiment. China's manufacturing purchasing managers' index increased to 49.8 in August, surpassing expectations but remaining below the 50-point mark, indicating mixed signals about economic growth.

Meanwhile, Japan's July industrial output rose by 0.1% from the previous month, outperforming forecasts for a 0.7% decline, and retail sales increased by 2.4% month-on-month, suggesting some level of domestic demand resilience. In India, investors anticipated volatility due to an upcoming MSCI index rebalancing, which could affect fund positions.

Nifty 50 futures in India slipped by 0.2%, reflecting cautious investor outlooks. On the positive side, Australia's S&P/ASX 200 gained 0.1%, and Singapore's Straits Times Index edged up by 0.4%, defying the regional downtrend.
