The United States Supreme Court’s decision to strike down President Donald Trump’s global tariffs, and his imposition of a 15% global tariff in response to the verdict, have concerned the world and its trade order. India and China seem to be among the biggest winners, while the United Kingdom appears to be the biggest loser from Trump’s latest order.

The US Supreme Court handed Trump a major setback when it cancelled several tariffs he had imposed during the global trade war. Just hours after the decision, Trump announced a fresh 10% duty on imports into the US from every country starting Tuesday, later increasing it to 15% on Saturday.

Right after Friday’s ruling, they fell to 10%, then rose to 15% on Saturday, the highest allowed under Section 122.

For India, the present 15% rate still improves on the 18% set in the bilateral framework revealed this month and is far lower than the 26% Liberation Day level.

On Monday, Beijing also urged the United States to cancel unilateral tariffs announced by Trump since “there are no winners in a trade war and protectionism leads nowhere”.

For countries such as China, which also had a 10% fentanyl tariff removed by the courts, exports now face less harsh rates.

Apart from Beijing, Mexico also had fentanyl-linked levies, so it benefits as those charges no longer apply.

Britain had been benefiting from a lower reciprocal tariff of 10% than many other countries, which gave it an edge, but Trump’s pledge to raise it to 15% for all nations means firms may now face steeper duties.

The UK is set to face the largest increase, followed by Italy and Singapore, according to Global Trade Alert, while Brazil, China and India are likely to gain the most.

UK officials are now urgently trying to convince the US administration to exclude it from the higher rate. The British Chambers of Commerce says this could increase costs on UK exports to the US by up to £3 billion ($4 billion) and affect 40,000 British companies.

“We are having conversations at the highest levels to make sure that what we regard as being in our national interest is heard loud and clear with our American counterparts,” cabinet minister Bridget Phillipson told Sky News on Sunday.

“A deal is a deal,” a commission statement said.

“As the United States’ largest trading partner, the EU expects the US to honour its commitments set out in the Joint Statement — just as the EU stands by its commitments,” it added.

The EU and the United States last year reached an agreement that set US tariffs at a maximum of 15 per cent on most European goods.

Bernd Lange, chairman of the parliament’s trade committee, said he will propose halting legislative work on approving the deal on Monday “until we have a comprehensive legal assessment and clear commitments from the US.”
