China shares slump by 8%

Chinese shares slid more than 8% yesterday as an unprecedented government rescue plan to prop up valuations ran out of steam, throwing Beijing’s efforts to stave off a deeper crash into doubt.

Major indexes suffered their largest one-day drop since 2007, shattering three weeks of relative calm in China’s volatile stock markets since Beijing unleashed a barrage of support measures to arrest a slump that started in mid-June.

“The lesson from China’s last equity bubble is that, once sentiment has soured, policy interventions aimed at shoring up prices have only a short-lived effect,” wrote Capital Economics analysts in a research note reacting to the slide.
