UK Trade Tensions Rise as Trump Signals New Deal and Potential Tariffs Amid Shifting Global Economic Landscape

Listeners, welcome to “United Kingdom Tariff News and Tracker.” Here’s your tariff and trade update for today, September 24, 2025. The global tariff landscape remains dynamic. According to S&P Global’s latest tracker, the worldwide average trade-weighted effective tariff rate stands at 16.9% as of September 9th, a slight dip from late August. For UK businesses and importers, this means marginally reduced average costs across select global markets, but still historically high by pre-pandemic standards—a symptom of still-elevated protectionism in world trade. Turning stateside, former US President Donald Trump recently signaled in an interview with Fox News that he’s actively working on a new trade deal with the United Kingdom, describing the talks optimistically and touting its potential benefits. At the same time, he doubled down on America’s readiness for “a heavy set of tariffs,” hinting at the possibility of a more confrontational approach to global trade—particularly with regard to China, India, and possibly with broader implications for all US trading partners, including the UK. These remarks have set the stage for nervous speculation among policymakers and exporters on both sides of the Atlantic, as further escalation could reshape the terms of trade and market access for major UK sectors. It’s important to note, as highlighted in The Wall Street Journal, that under the Trump administration, the UK managed to secure a baseline US tariff of 10%, which is lower than the 15% rate imposed on the European Union. Key products like steel and cars benefited from this arrangement. According to trade policy expert Kelly Ann Shaw, this preferential treatment allows the UK to enjoy one of the most favorable trading relationships with the US among America’s partners, though some UK exports still face higher duties in select categories. Meanwhile, the United States and European Union finalized a landmark trade agreement last month, tightening coordination on key sectors like steel, aluminum, and advanced manufacturing. The pact enshrines preferential access for each party, ring-fences quotas, and sets stringent “rules of origin,” making it harder for non-bloc countries—including the UK now that it’s outside the EU—to access these vast markets with value-added goods. This deepened transatlantic collaboration on tariffs and industrial policy is already incentivizing smaller economies to reassess strategic alliances. Alongside trade developments, US-UK energy tensions remain in the spotlight. Trump has criticized Britain’s move away from North Sea oil, suggesting it may imperil energy security and trade alignments between the two countries. For UK companies and those trading with Britain, the months ahead are likely to bring fresh negotiations and shifting ground rules, especially if new tariffs or bilateral deals take shape.
