Confusion continues as to whether Donald Trump’s new 15% tariffs kick in tomorrow in the UK or the European Union, despite the US trade representative Jamieson Greer’s assurances that nothing changes for the 20-odd countries the US has already agreed tariff deals with.The new president of the British Chambers of Commerce, Andy Haldane, told the BBC he believed that the 15% tariffs did apply from tomorrow unless the government hears otherwise.Haldane told the BBC Today programme:double quotation mark“We are 10% [tariff rate with the US].If he [Trump] follows through tomorrow, that will be 15% and that will mean UK sits towards the bottom the league table in terms of who’s been made worst off by the measures of the weekend.”And the German confederation of businesses, BDI, called on the EU to “quickly approach the US and provide clarity on tariffs and trade rules”.

With European stock markets down today, and analysts warning of an ‘unholy mess’ of tariff confusion, BDI president Peter Leibinger said:double quotation mark“These decisions create significant new uncertainty for transatlantic trade,Businesses on both sides of the Atlantic urgently need planning certainty and reliable trading conditions,The EU, with the support of the German government, should quickly approach the United States and provide clarity on tariffs and trade rules,Only through dialogue can transparency be established and trust in transatlantic economic relations be secured,”On Sunday Greer told CBS that the US will not back out of tariff deals it has already sealed with countries around the world, including the UK, the EU, Japan, Switzerland and others.

“We want them to understand these deals are going to be good deals,” Greer said.“We’re going to stand by them.We expect our partners to stand by them.”In a strongly worded statement, the EU called on the US not to walk back the July deal.“A deal is a deal,” it said, adding:double quotation mark“As the United States’ largest trading partner, the EU expects the US to honour its commitments.

”Adding to the confusion, there’s also uncertainty whether the new 15% tariffs are legal,That’s because Trump is using section 122 of the Trade Act of 1974, which gives the president the power to impose surcharges and import restrictions to tackle international payments problems,But some experts are questioning how the US can have a balance-of-payments problems in an era of floating exchange rates,Gita Gopinath, the former first deputy managing director of the International Monetary Fund, declared yesterday that the US does not have a fundamental international payments problem:Wearing my (former) IMF hat I will say that the US does not have a fundamental international payments problem,A balance of payments (BoP) problem arises when a country loses market access or is close to losing market access.

As long as there is plenty of demand for US debt and equities, which is the case, the US does not have a 'payments' problem.It can finance its trade deficits…Atakan Bakiskan, economist at Berenberg, has written about this issue:double quotation markAre the new tariffs even legal? The new Section 122 tariffs may also face court challenges, as the current US trade deficit may not meet the condition of “large and serious balance-of-payments” deficits that grant the president authority to impose tariffs to address “fundamental international payments problems.”First of all, isn’t the balance of payments always equal to zero as an accounting identity under a flexible exchange rate regime? Second, what qualifies as “large and serious”? No president has ever invoked Section 122 before, so any legal challenge will likely take time to resolve.The EU has said “additional clarity” is required from the US as to whether the tariff agreement it struck last July in Scotland still stands, after Donald Trump announced a new global tariff of 15% on Saturday.‘We are very clear what needs to happen here.

The US needs to tell us precisely what is going on,Our intention is to continue implementing the aspects of the agreement we made with the US,” said trade spokesman Olof Gill,Gill added:double quotation mark“Additional clarity is required,And I think it’s very fair to say that full clarity on what these new developments mean for the EU US trade relationship is the absolute minimum that is required in order for us as the EU to make a clear eyed assessment and decide on next steps,”The German chancellor Friedrich Merz has said he expects Donald Trump to respect the tariff deal struck last July at his Scottish golf course.

As confusion reigns across the globe as to whether the new 15% tariff rate, announced by the US on Saturday, would be implemented for the UK, the EU and others, Merz’s spokesperson said:double quotation mark“We expect the US to follow the Supreme Court of the US decision with clear policies.”The EU on Sunday called on the US to honour the July agreement.“A deal is a deal” it said.The new 15% tariff rate Trump says he will impose from tomorrow flows from powers in the 1974 Trade Act, a different legal framework to the reciprocal tariffs Trump imposed unilaterally last year on dozens of countries.They can only hold for 150 days and must then get congressional approval.

Asia should emerge as a beneficiary of the US tariff reset, as the removal of the IEEPA tariffs by the supreme court lowers effective tariff rates for key exporters like India, China, and Vietnam, says ING analyst Deepali Bhargava.Bhargava says China stands to gain meaningfully from the removal of IEEPA tariffs, while the supreme court ruling arguably improves India’s negotiating position as it hammers out an interim trade deal with the US.Vietnam, meanwhile, could be the region’s biggest winner, as the move to a flat 15% tariff will make an even more favourable production base for US-bound goods.While Japan and South Korea gain little on tariffs alone, their strategic trade and investment deals with the US should continue as planned, Bhargava adds.The European Parliament is set to pause the process of ratification of the trade deal with Donald Trump later this afternoon, the lead negotiator of the conservative group of MEPs has said.

The parliament has already paused the deal once, over Trump’s threat to Greenland, but unpaused earlier this month with a vote of all MEPs expected in March to formally ratify the agreement.Bernd Lange, chair of the International Trade Committee of the European Parliament, has convened an extraordinary meeting on Monday following the supreme court ruling in the US striking down the tariffs as illegal.Zeljana Zovko, the lead trade negotiator in the European People’s Party group on the US deal told Bloomberg that “we have no other option” but to delay the approval process to seek to clarity on the situation.Potential shockwaves from Donald Trump’s global 15% U.S.

tariff could disrupt UK supply chains overnight, warns Dr Jonathan Owens, senior lecturer in operations management and global supply chain expert at the University of Salford.double quotation markIf implemented, a 15% tariff policy under Donald Trump could send immediate shockwaves through UK supply chains, despite the measures being imposed by the United States.The UK is tightly woven into global trade networks, and many British firms either export directly to the U.S.or supply critical components that feed into American markets.

A sudden cost barrier of this scale would not be contained within U.S.borders and could ripple quickly across the Atlantic.In the short term, higher U.S.

import costs would likely suppress demand for UK goods, particularly in strategically vital sectors such as automotive manufacturing, aerospace, machinery, and pharmaceuticals.British suppliers embedded in transatlantic production lines could face abrupt order cancellations, forcing production cuts and leaving warehouses with unsold inventory.For smaller firms operating on thin margins, such disruption could quickly escalate into a cash-flow crisis.The indirect fallout could be equally destabilising, Owens continues:double quotation markCountries hit by falling U.S.

demand may flood European markets with surplus goods, intensifying price competition and squeezing UK manufacturers,At the same time, currency volatility could surge, driving up hedging costs and injecting further unpredictability into procurement and pricing strategies,Logistics networks would not escape unscathed, as shipping routes could be rapidly reconfigured as firms scramble to avoid tariff exposure,This could lead to port congestion, delivery delays, and rising freight costs,While the long-term consequences would depend on political negotiations, the immediate impact would be clear: heightened uncertainty, mounting cost pressures, and a period of acute supply chain turbulence as UK businesses fight to remain resilient.

However, this could ultimately prove to be little more than a burst of political theatre, generating headlines rather than lasting economic damage.If the policy were short-lived, disruption to UK supply chains might be sharp but brief.Confusion continues as to whether Donald Trump’s new 15% tariffs kick in tomorrow in the UK or the European Union, despite the US trade representative Jamieson Greer’s assurances that nothing changes for the 20-odd countries the US has already agreed tariff deals with.The new president of the British Chambers of Commerce, Andy Haldane, told the BBC he believed that the 15% tariffs did apply from tomorrow unless the government hears otherwise.Haldane told the BBC Today programme:double quotation mark“We are 10% [tariff rate with the US].

double quotation markA flat tariff rate of 15% seems, at face value, less confusing than multiple tariff rates.Nevertheless, this will apply for up to five months, after which, no exporter (or even importer) will know what to expect next.The main issue is that in anticipation of the mid-term elections towards the end of the year, and with US inflation (the Fed’s preferred measure) already at 2.9%, Trump might (or might not) be willing to lower tariffs from 15%.The problem for the UK economy remains a significant one, not least because my recent paper shows that trade uncertainty, again on the rise, is a major driver of future GDP and CPI inflation developments…The supreme court ruling against Donald Trump’s IEEPA tariffs is creating new cracks in the president’s “electoral-fiscal-trade” trilemma, says Grace Fan of City consultancy TS Lombard.

Fan writes:double quotation markStill, Trump’s trilemma (electoral-fiscal-trade) – in a midterm election year in which Trump’s approval rating is tanking – means the great tariff reshuffle has just begun.With the administration’s top priorities shaping up to be voters and jittery bond markets, look for the White House to dial down tariffs further on targeted consumer items this year to address the affordability crisis, while ratcheting up Sec.232 (national security) and 301 (“unfair” trade) tariffs to plug the IEEPA tariff revenue hole with Sec.122 set to expire in August.Likely losers are select industrial sectors, with the burden falling on both US importers and across core trading partners (USMCA, Asia, EU).

Former Amazon boss Doug Gurr has been named as the preferred candidate to chair Britain’s competition watchdog, despite criticism of his appointment as interim chair a year ago.Business secretary Peter Kyle has announced that Gurr is his choice of candidate to continue as chair of the Competition and Markets Authority (CMA), “following an open competition for the role”.Kyle said the CMA has been playing a key role delivering the government’s pro-growth agenda under Gurr’s leadership since last January.He was appointed interim chair in early 2025, after the government grew frustrated that the CMA was not doing enough to support growth, and forced out its chair, Marcus Bokkerink.Gurr’s appointment as interim chair was controversial, though; it was called a “slap in the face to workers” by trade unions and Trumpian by consumer activists.

It prompted fears that the CMA would wave through business deals without the necessary scrutiny, if bosses could claim they’d be good for growth.Financial markets are being being “rattled by fresh trade uncertainty”, reports Susannah Streeter, chief investment strategist at Wealth Club:double quotation mark“The rip-roaring performance of the Footsie has been interrupted as fresh trade chaos mars the party.The exuberance that flashed over global markets after the US Supreme Court rejected Trump’s tariffs as unconstitutional is evaporating.The President is using a backdoor via the Trade Act to reimpose temporary blanket tariffs of 10% and has threatened to increase the rate to 15%.Bilateral deals reached through tortuous negotiations have been thrown up in the air again, creating a cloud of uncertainty.
