China's indexes traded down at the start of a new week as investors adjusted their growth outlook for artificial intelligence infrastructure spending. 

The Hang Seng Index increased 0.3%, and the mainland-focused CSI 300 Index decreased 0.3% after leading AI firms called for a slowdown in the technology's development. 

In the previous week, Hong Kong and mainland China indexes faced heavy selling pressure led by metals and tech stocks as global bond yields continued to advance.  

After a week of volatile trading, the Hang Seng index dropped 3.9%, and the CSI 300 Index eased 2%.

Global markets finished the week lower as escalating U.S.-Iran hostilities pushed crude oil prices over $100, fueling inflation and interest rate anxieties. The U.S. 10-year Treasury yield approached 5% and jumped 100 basis points in seven months.

Domestically, investors shifted their attention to a raft of economic data due later in the week, including fixed-asset investment, house prices, industrial output, retail sales, and the jobless rate. 

Chinese president Xi Jinping proposed establishing an open-source AI community among BRICS member nations, deepening cooperation in developing large language models. 

Prime Minister Narendra Modi chaired the two-day meetings at Bharat Mandapam in New Delhi, attended by the leaders of Russia, China, the UAE, Iran, South Africa, and Malaysia, and delegations from several other nations.  

The crude oil price advanced on Monday amid growing worries of supply disruption in the Middle East.  

Oil prices surged as much as 3% after Saudi Arabia closed a critical crude pipeline following drone attacks, disrupting a key route used to bypass the Strait of Hormuz.

Brent crude oil price jumped 3% to $108 a barrel after rallying almost 9% last week and reaching a new seven-week high.

 

China Indexes and Stocks 

The Hang Seng Index increased 0.3% to 24,876.27, and the mainland-focused CSI 300 Index decreased 0.3% to 4,495.98. 

AI- and semiconductor-linked stocks led decliners in Monday's trading amid weakening confidence in artificial intelligence trade. 

Zhongji Innolight decreased 4.9% to ¥880.15, Cambricon Technologies added 0.7% to ¥1,046.94, Victory Giant Technology fell 1.2% to HK $197.20, and Eoptolink Technology declined 4.1% to ¥405.76.
