Sembcorp Industries' stock soared 3.05% intraday, leading gains on the Singapore benchmark index amid a broad regional rally.

The surge in Sembcorp Industries and other Asian equities was driven by renewed investor optimism following hopes for a resumption of U.S.-Iran peace talks. This diplomatic development calmed markets, sent oil prices lower, and lifted appetite for risk-sensitive assets across emerging Asia.

As a key component of the Singapore market, Sembcorp Industries benefited from this improved risk sentiment, which supported a relief rally in regional stocks leveraged to trade and economic growth.
