More ships to call at Singapore? How the Iran war and tariffs are reshaping global sea trade
Geopolitical disruptions, including the Iran war and rising tariffs, have begun redrawing global shipping routes. Industry watchers say the risks could push more carriers toward alternative hubs, including Singapore.

The ongoing conflict between Iran and the US is directly affecting shipping routes around the Gulf and the Strait of Hormuz. Carriers are reassessing their paths to avoid heightened security risks in the region.
At the same time, rising global tariffs are adding pressure on companies to diversify their supply chains. Industry representatives say the combination of these two trends could boost demand for strategically located hubs such as Singapore.
Analysts expect shipping operators to keep rebalancing security and cost considerations, a shift they say could strengthen the role of Southeast Asian ports in global trade.
