US trading partners in Asia started weighing fresh uncertainties yesterday after President Donald Trump vowed to impose a new tariff on imports, hours after the Supreme Court struck down many of the sweeping levies he used to launch a global trade war.
The court’s ruling invalidated a number of tariffs that the Trump administration had imposed on Asian export powerhouses from China and South Korea to Japan and Taiwan, the world’s largest chip maker and a key player in tech supply chains.
Within hours, Trump said he would impose a new 10 percent duty on US imports from all countries starting on Tuesday for an initial 150 days under a different law, prompting analysts to warn that more measures could follow, threatening more confusion for businesses and investors.

In Japan, a government spokesman said Tokyo “will carefully examine the content of this ruling and the Trump administration’s response to it, and respond appropriately.”
China, which is preparing to host Trump late next month, has yet to formally comment or launch any counter moves with the country on an extended holiday. But a senior financial official in China-ruled Hong Kong described the US situation as a “fiasco.”
Hong Kong Secretary for Financial Services and the Treasury Christopher Hui (許正宇) said Trump’s new levy served to underscore Hong Kong’s “unique trade advantages.”

“This shows the stability of Hong Kong’s policies and our certainty ... it shows global investors the importance of predictability,” Hui said at a media briefing yesterday when asked how the new US tariff’s would affect the city’s economy.
Hong Kong operates as a separate customs territory from mainland China, a status that has shielded it from direct exposure to US tariffs targeting Chinese goods.
While Washington has imposed duties on mainland exports, Hong Kong-made products have generally faced lower tariff rates, allowing the city to maintain trade flows even as Sino-US tensions have escalated.
Before the Supreme Court’s ruling, Trump’s tariff push had strained Washington’s diplomatic relations across Asia, particularly for export-reliant economies integrated into US-bound supply chains.
Friday’s ruling concerns only the tariffs launched by Trump on the basis of the International Emergency Economic Powers Act, or IEEPA, intended for national emergencies.
Trade policy monitor Global Trade Alert estimated that by itself, the ruling cuts the trade-weighted average US tariff almost in half from 15.4 percent to 8.3 percent.
For those countries on higher US tariff levels, the change is more dramatic. For China, Brazil and India, it will mean double-digit percentage point cuts, albeit to still-high levels.
In Taiwan, the government said it was monitoring the situation closely, noting that the US government had yet to determine how to fully implement its trade deals with many countries.
“While the initial impact on Taiwan appears limited, the government will closely monitor developments and maintain close communication with the US to understand specific implementation details and respond appropriately,” a Cabinet statement said.
Taiwan has signed two recent deals with the US — one was a Memorandum of Understanding last month that committed Taiwan to invest US$250 billion and the second was signed this month to lowering reciprocal tariffs.
Analysts said that the Supreme Court’s ruling against Trump’s more aggressive tariff measures might offer little relief for the global economy. They warned of looming confusion as trading nations brace for moves by Trump to find other means of using levies to circumvent the ruling.
Thailand’s Trade Policy and Strategy Office head Nantapong Chiralerspong said the ruling might even benefit its exports as uncertainty drove a fresh round of “front loading,” where shippers race to move goods to the US, fearing even higher tariffs.
In corporate disclosures tracked by Reuters, firms across the Asia-Pacific region reported financial hits, supply shifts and withdrawals as levies escalated through last year and early this year.
South Korea said the US Supreme Court ruling would not derail its broader trade agreement with Washington.
South Korean Industry Minister Kim Jung-kwan held an emergency meeting yesterrday to assess the decision. The ruling renders void the 15 percent reciprocal tariff currently applied to South Korean goods, the Ministry of Trade, Industry and Resources said in a statement.
“Although the ruling has heightened uncertainty over exports to the US, the overall framework of export conditions secured under the Korea-US tariff agreement will remain intact,” Kim said, pledging a full-scale response to protect national interests and Korean companies.
Sectoral tariffs on automobiles and steel, imposed under separate laws, remain in place, and are unaffected by the court’s decision, the ministry said.
Seoul said it would closely monitor Washington’s follow-up measures, while continuing talks on the implementation of last year’s trade agreement.
The ruling comes against an already fragile tariff backdrop between Seoul and Washington. The US imposed a 15 percent tariff on South Korean imports, including autos, under a deal that features a US$350 billion investment commitment. Trump last month also warned of a possible tariff increase, citing delays in South Korean legislation needed to implement the pledge.
The presidential Blue House said it would comprehensively review the court ruling and the US government’s position, and would proceed in a direction that best serves the national interest.
Seoul said it would monitor US developments on potential refunds of the now-voided reciprocal tariffs and work with business groups to support affected companies.
Nanya Technology Corp (南亞科技) yesterday said the DRAM supply crunch could extend through 2028, as the artificial intelligence (AI) boom has led the world’s major memory makers to dramatically reduce production of standard DRAM and allocate a significant portion of their capacity for high-bandwidth memory (HBM) chips. The most severe supply constraints would stretch to the first half of next year due to “very limited” increases in new DRAM capacity worldwide, Nanya Technology president Lee Pei-ing (李培瑛) told a news briefing. The company plans to increase monthly 12-inch wafer capacity to 20,000 in the first half of 2028 after a
Property transactions in the nation’s six special municipalities plunged last month, as a lengthy Lunar New Year holiday combined with ongoing credit tightening dampened housing market activity, data compiled by local land administration offices released on Monday showed. The six cities recorded a total of 10,480 property transfers last month, down 42.5 percent from January and marking the second-lowest monthly level on record, the data showed. “The sharp drop largely reflected seasonal factors and tighter credit conditions,” Evertrust Rehouse Co (永慶房屋) deputy research manager Chen Chin-ping (陳金萍) said. The nine-day Lunar New Year holiday fell in February this year, reducing
Taiwan has enough crude oil reserves for more than 100 days and sufficient natural gas reserves for more than 11 days, both above the regulatory safety requirement, Minister of Economic Affairs Kung Ming-hsin (龔明鑫) said yesterday, adding that the government would prioritize domestic price stability as conflicts in the Middle East continue. Overall, energy supply for this month is secure, and the government is continuing efforts to ensure sufficient supply for next month, Kung told reporters after meeting with representatives from business groups at the ministry in Taipei. The ministry has been holding daily cross-ministry meetings at the Executive Yuan to ensure
New vehicle sales in Taiwan plunged about 37 percent sequentially last month as the long Lunar New Year holiday and 228 Peace Memorial Day holiday cut short the number of working days, along with the lingering uncertainty over import tax cuts on US vehicles, market researcher U-Car said in a report yesterday. New car sales last month totaled 22,043, slumping from 35,073 units in January and down 19.89 percent from 37,515 in February last year, U-Car data showed. Sales of imported luxury cars, led by Mercedes-Benz, plummeted about 45 percent to 3,109 units last month from 5,663 units in the previous month,
