China's blue chips slide as tech rout and Gulf tensions spook investors

what happened

Chinese equities slipped on Friday as a sell-off in technology shares on Wall Street weighed on sentiment worldwide, according to Reuters. The Shanghai Composite lost 0.9% in early trade and the CSI300 blue-chip gauge shed 1.1%, extending the previous session's declines. Hong Kong's Hang Seng was roughly flat.

The CSI300 closed the prior session at its lowest level since July 2025, while the Shanghai benchmark finished at its weakest point in over a year. The index now trades more than 20% under its June 22 closing peak, a drop that satisfies some bear-market criteria. Under the most widely used definition, it has been in a bear market since its 2007 closing high.

UOB analysts pointed to three pressures hitting markets at once: a deepening retreat in AI-linked tech stocks, rising Middle East tension after deadly strikes on Saudi Aramco facilities, and growing strain in French sovereign debt markets. Together, they prompted a fast move away from riskier assets overnight.

why it matters

For global investors, the episode shows how China's equity slump is now tied to US technology shares and European debt markets, not only to domestic factors. The CSI300's slide below the bear-market threshold raises attention on whether the weakness spreads to other Asian exchanges.
