Title: Shanghai Composite Index Hits 10-Year High Amid Trade Tensions and Strong Domestic Demand

The Shanghai Composite Index (SSEC) closed at 3,728 on Monday, marking its highest level in a decade and the highest since August 2015 [1]. The index rose 0.9%, driven by a shift of capital from bonds to equities, with small investors playing a key role in the surge [2]. Turnover on mainland exchanges exceeded 2.7 trillion yuan, while margin debt reached levels not seen since 2015, indicating strong investor participation [3].

This upturn followed a 20% rebound from the April slump triggered by sweeping U.S. tariffs under Donald Trump. A recent extension of the tariff truce provided further reassurance, helping to restore confidence among Chinese investors [4]. The market’s performance also reflects a broader shift in capital as investors rotate out of fixed-income assets amid reduced expectations for aggressive monetary easing [5].

Fund managers have expressed optimism about the sustainability of the rally, pointing to ample liquidity, government measures to curb price wars, and cautious economic stabilization. Wang Huan, a fund manager at Shanghai Zige Investment Management Co. Ltd., stated that the current upturn appears more firmly supported than previous rallies, citing growing interest in artificial intelligence and policy-driven economic support [6].

Despite the strong performance, the index remains below its 2015 peak of 5,166 and its historical high of 6,124 recorded in October 2007. However, the rally has contributed to a broader global market upswing, with U.S. and Indonesian stocks reaching record levels [7]. On the mainland, trading activity has surged, with the Shanghai Composite up 11% year-to-date, outpacing the 8% gain of the CSI 300 Index [8].

The increased demand has extended to Hong Kong, where mainland investors purchased a record 35.9 billion Hong Kong dollars of shares on Friday. Leverage has also risen, with margin debt reaching its highest level since 2015. Authorities have introduced policy adjustments, including tighter enforcement of taxes on overseas stock trades and subsidies for eligible personal consumer loans, to channel funds into domestic equities [9].

Analysts remain cautious but optimistic, noting that a combination of improved sentiment, tighter bond market policies, and official support will determine whether the current rally can be sustained. The market is closely watching for signs that the positive momentum will continue into the broader economic recovery [10].
