China index rebalancing to trigger $48B in passive flows by June 12

Goldman Sachs is projecting that the semi-annual rebalancing of China’s major stock indices will unleash over $48 billion in gross two-way passive investment flows by mid-June. That’s not net buying or selling. It’s the total volume of capital that passive funds will be forced to move as they adjust their holdings to match updated index compositions.

What’s actually changing

The rebalancing was officially announced after market close on May 30. It touches a broad swath of China’s equity benchmarks: the CSI 300, CSI 500, CSI 1000, SSE 50, SSE 180, STAR 50, and several Shenzhen indices including the Shenzhen Component and ChiNext.

The bulk of the adjustments take effect after trading closes on June 12. Shenzhen index modifications follow shortly after on June 15.
