China and Hong Kong Markets Rally on Strait of Hormuz De-escalation

The CSI300 Index, a key barometer for Chinese blue-chip stocks, led the surge with a 2.4% gain. The Shanghai Composite Index mirrored this upward momentum, closing 1.6% higher as market participants reacted to the removal of a significant geopolitical risk factor. In Hong Kong, the Hang Seng Index followed suit, posting a 0.5% increase by the final bell.

Energy security remains the primary driver behind this sudden influx of capital. By securing the Strait of Hormuz—the world’s most vital maritime oil chokepoint—the agreement provides a rare window of predictability for energy-dependent industries. This cooling of regional tensions has replaced months of anxiety with a renewed appetite for risk, setting a bullish tone for regional trade.
