The imposition of new US tariffs could significantly disrupt global security dynamics, according to Home Affairs Minister K. Shanmugam. Mr. Shanmugam emphasized that a departure from a rules-based international system forces countries to increasingly focus on their own security interests.
US Tariff Policies Trigger Uncertainty in International Relations
This caution comes in response to US President Donald Trump’s decision on April 2 to introduce broad-based tariffs. Under this new directive, a standard 10 per cent tariff will be enforced on all imports entering the US, impacting even close partners like Singapore. Additionally, harsher, reciprocal tariffs have been levied against no fewer than 60 trading partners globally.
Potential Long-Term Consequences on Global Trade Landscape
Mr. Shanmugam highlighted the unpredictability of the current environment, noting that it remains unclear whether this shift is a temporary maneuver or a permanent change in US trade policy. He pointed out that if the world’s largest economy embraces protectionism, other nations may be compelled to follow suit by introducing their own trade barriers and incentives.
Security Implications for Smaller States like Singapore
The Home Affairs Minister underlined that this global drift away from cooperative trade practices could have direct security implications, especially for smaller countries like Singapore. As the balance of power and economic relationships are redefined, nations may increasingly have to fend for themselves without the protections offered by a stable international order.
Regional Efforts to Uphold Global Trade Stability

Addressing these challenges, Mr. Shanmugam shared that Prime Minister Lawrence Wong, together with like-minded leaders from other countries, is actively working to uphold the global trading system. Their efforts aim to preserve some degree of international order despite the overwhelming influence of the US on global consumption patterns.
Limitations in Countering America’s Dominant Role
However, Mr. Shanmugam acknowledged that the combined efforts of smaller nations cannot fully replace the pivotal role played by the United States, which accounts for roughly a third of global consumption. While establishing alternative frameworks could bring some stability, he cautioned that it would not completely offset the consequences of US actions.
Singapore Braces for Heightened Stress Amid Global Shifts
Referring to Prime Minister Wong’s speech at the 14th S. Rajaratnam Lecture on April 16, Mr. Shanmugam noted that Singapore is prepared to act with agency but must also brace for considerable stress. The evolving global environment demands resilience and adaptability from smaller nations facing increased vulnerability.
Navigating an Uncertain Future in Global Security and Trade
In conclusion, Mr. Shanmugam reiterated that Singapore must stay proactive and alert in the face of growing protectionist tendencies worldwide. As the traditional rules governing global interaction weaken, the city-state is reinforcing its commitment to safeguarding its economic and security interests amid these turbulent changes.
