Chinese equities delivered an astonishing turnaround in late September 2026, culminating in the CSI 300 Index's most explosive single-week rally since the global financial crisis in November 2008. The onshore benchmark advanced 15.7% across five frantic trading sessions, propelled by a tsunami of domestic and overseas capital responding to Beijing's decisive macroeconomic rescue package.

The dramatic re-rating gathered steam after the People's Bank of China (PBOC), alongside securities regulators and top leadership, unveiled an unprecedented multi-pronged offensive. Measures included steep cuts to benchmark interest rates, lowered reserve requirement ratios (RRR) releasing roughly 1 trillion yuan in liquidity, and groundbreaking swap facilities granting institutional investors direct PBOC funds to purchase domestic shares.

Simultaneously, policymakers addressed the protracted real estate downturn by slashing existing mortgage rates by an average of 50 basis points and reducing minimum down payments for secondary home purchases to 15%. This coordinated fiscal and monetary posture signaled a pivotal shift in Beijing's approach toward tackling deflationary headwinds.

Market activity broke historical milestones as aggregate daily trading volume across the Shanghai and Shenzhen bourses repeatedly shattered records, exceeding 1.4 trillion yuan. Trading terminals at prominent domestic brokerages briefly experienced execution latency due to overwhelming traffic from retail investors opening accounts and depositing fresh collateral.

Trading Frenzy and Outlook for Golden Week Liquidity

Consumer discretionary, technology, and property development shares spearheaded the gains, with heavily shorted blue-chip conglomerates experiencing sharp short-covering spikes. International hedge funds, which had held underweight positions in Chinese equities for quarters, reversed course rapidly to rebalance exposures against rising benchmarks.

As the nation heads into the week-long Golden Week national holiday recess, market analysts anticipate that elevated consumer sentiment and retail spending data will provide further fundamental validation for the sustained equity recovery, setting an optimistic tone for fourth-quarter earnings.
