Shanghai and Shenzhen margin balances rise 12.07 billion yuan in one day

The leverage build-up is concentrated in Shanghai, which absorbed the bulk of the single-day increase, suggesting the appetite for margin exposure is not evenly spread across the two boards. This matters because margin balances are a proxy for how much risk domestic traders are willing to carry, and a combined total above two trillion yuan signals that leverage remains a meaningful part of turnover. Whether the Shanghai-led pace continues, or reverses as it often does after sharp single-day jumps, is the open question worth tracking in the sessions ahead.
