What the Latest US Tariffs Mean for Singapore and Asia?
Last Friday, the US Supreme Court ruled that President Trump could not rely on the 1977 International Emergency Economic Powers Act (IEEPA) to impose his “reciprocal” tariffs on imports from every country. However, within hours of the decision, President Trump signed a new proclamation invoking Section 122 of the 1974 Trade Act. This alternative provision allows him to impose a temporary tariff of up to 15% for a period of 150 days, after which Congressional approval would be required.
Initially set at 10%, the tariff was subsequently raised to the maximum 15% permitted under the statute , a provision that has never previously been used. The new tariff will take effect from Tuesday, 24 February 2026.
While the Supreme Court’s ruling represents a clear legal setback to the administration’s earlier tariff strategy, it provides little immediate relief to the global economy. Uncertainty persists, not least because the President has consistently demonstrated a willingness to use tariffs as a primary instrument of economic leverage.
Across Asia, governments are now assessing what both the court ruling and the new blanket global tariff may mean for trade relations with the United States. Businesses, meanwhile, are largely adopting a wait-and-see approach, as they have done in previous episodes when tariff measures were announced before operational details were clarified.
Singapore’s Ministry of Trade and Industry has stated that it is monitoring developments closely and will seek further clarification from US authorities, particularly regarding implementation details and whether any tariff refund mechanisms will be introduced.
Trump’s latest announcement is unlikely to significantly unsettle Asian businesses. Many have already adjusted to operating in an environment shaped by policy unpredictability. Since “Liberation Day,” when a broad package of import duties was first unveiled, global trade dynamics have shifted towards what some describe as a “World minus One” framework.
The administration has argued that tariffs are necessary to reduce the US goods trade deficit. However, the US trade deficit widened further in 2025, rising by 2.1% from 2024 to approximately US$1.2 trillion.
Several major conglomerates from Japan and South Korea have pledged substantial investments in the United States, with some projects already underway. These investments could face delays if higher tariffs disrupt machinery procurement. Equally, the impact could prove negligible if exemptions are granted. In either scenario, the prevailing uncertainty may contribute to delays in further investment commitments.
There is, however, a potential offsetting dynamic. If US businesses interpret the 15% tariff as temporary, they may front-load imports over the next five months to take advantage of what could be viewed as relatively lower tariff levels. In that case, Asia , including trade-dependent Singapore , could see a modest lift in export activity.
The Bottom Line
Immediate disruption appears limited, but uncertainty remains elevated. Asian businesses are largely taking a cautious approach, yet prolonged ambiguity could weigh on investment decisions. For Singapore, there may be marginal benefit if front-loading of US imports boosts trade flows in the near term. Ultimately, outcomes will depend on implementation details and the scope of any exemptions.
