Chinese stocks sink to 13-month low as tech shares tumble on oil, rates concerns

Mainland Chinese stocks plummeted to their lowest levels in over a year on Monday, driven by a sharp sell off in the technology sector. Investors appeared spooked by a combination of soaring energy costs and high interest rates, leading many to pull back from riskier assets just as a scheduled holiday break approached. The CSI 300 Index bore the brunt of the pessimism, sliding 2.2 percent to reach a valuation not seen since August of last year.

The carnage was most evident in the chip making industry, where the Star Market 50 index crashed by 4.1 percent. This marked the worst single day for the index in five weeks, bringing it perilously close to the lows experienced during a similar technology rout back in July. While mainland markets struggled, Hong Kong provided a small silver lining as the Hang Seng Index managed to defy the broader downward trend, edging up slightly by 0.6 percent.

Much of the volatility is being attributed to geopolitical tensions affecting global commodities. Crude oil surged past 100 dollars a barrel after the United States rejected an Iranian proposal regarding maritime traffic through the Strait of Hormuz. This spike in energy prices has reignited fears of stubborn inflation, which in turn keeps U.S. Treasury yields elevated and makes borrowing more expensive for growth dependent companies across Asia.
