President Donald Trump announced Saturday that the United States will impose blanket tariffs of 30 per cent on all goods from the European Union and Mexico beginning 1 August, marking a significant escalation in his administration’s global trade war that has already roiled financial markets and raised concerns about inflation.
The announcement, made through letters posted on Trump’s Truth Social platform, threatens to disrupt trade relationships worth more than £900 billion annually and could significantly impact consumer prices on both sides of the Atlantic. Trump warned that tariffs could rise even higher if either the EU or Mexico retaliates against the new levies.
The 27-member European Union represents America’s largest trading partner, with £480 billion worth of imports into the US in 2024, surpassing Mexico, Canada, and China. Pharmaceuticals and medical products constitute the largest category of EU exports to America, valued at approximately £100 billion annually, followed by motor vehicles, aircraft, and heavy machinery.
Border Security Concerns Drive Mexico Tariffs
In his letter to Mexican President Claudia Sheinbaum, Trump linked the tariffs directly to border security concerns, stating that whilst Mexico had been “helping me secure the border,” the efforts were insufficient. “Mexico still has not stopped the Cartels who are trying to turn all of North America into a Narco-Trafficking Playground,” the president wrote.
Mexico, which exported £400 billion worth of goods to the United States in 2024, supplies 69 per cent of America’s vegetable imports and 51 per cent of fresh fruit imports, according to US Agriculture Department data. Industry experts warn that the short shelf life of these products could lead to rapid price increases for American consumers.
The Mexican government has yet to issue a formal response to the tariff announcement, though President Sheinbaum has previously emphasised the importance of maintaining strong trade relations with the United States whilst defending Mexico’s sovereignty.
EU Prepares Retaliatory Measures
European officials, who have been engaged in intensive negotiations to avoid the tariff imposition, expressed disappointment at the announcement. EU Trade Commissioner Maroš Šefčovič had stated earlier this week that negotiations were happening “every single day” between Brussels and Washington, noting that the bloc had thus far avoided the higher tariffs imposed on other nations.
The European Commission has more than £80 billion worth of retaliatory tariffs on standby that can be quickly implemented, according to trade officials. These countermeasures specifically target politically sensitive American exports, including soybeans from Louisiana, bourbon from Kentucky, and Boeing aircraft.
We want to give negotiations a chance,” European Commission President Ursula von der Leyen said in recent remarks, whilst warning that “if negotiations are not satisfactory, our countermeasures will kick in.
Market Volatility and Economic Impact
Financial markets, which had spent much of the week dismissing earlier tariff threats, showed signs of concern following Saturday’s announcement. The Stoxx Europe 600 index had fallen 1.7 per cent earlier in the week when Trump first floated the possibility of higher EU tariffs.
Analysts at Citi warned that the new tariffs could exacerbate inflation concerns. Higher tariffs going into effect in August also could mean that inflationary effects come through later this year or even into next year, extending the timeline on higher inflation,” the bank noted in a client report.
The tariff announcement represents a significant escalation from Trump’s initial “Liberation Day” rollout in April, when the EU faced a 20 per cent levy. The new 30 per cent rate is 10 percentage points higher than what the president had previously indicated for America’s largest trading partner.
Pharmaceutical Trade Under Threat
Of particular concern is the potential impact on pharmaceutical trade between the EU and US. Ireland alone exported £52 billion worth of pharmaceutical products to America in 2024, whilst Germany, Belgium, and Italy are also major suppliers. Any disruption to this trade could affect drug availability and prices in the United States.
The pharmaceutical sector has already been under scrutiny, with the Trump administration launching investigations into the industry citing national security concerns. EU officials have strongly rejected these characterisations, with trade official Elena Kamilarova stating, “We do not agree with the concept… namely, looking at it as if imports of pharmaceuticals can pose national security risks.”
Agricultural Impact Looms Large
For Mexico, the agricultural sector stands to bear the brunt of the new tariffs. The country exported £24 billion worth of agricultural products to the United States in 2024, with avocados valued at £2.4 billion, tomatoes at £2 billion, and peppers at £1.2 billion forming the top categories.
Tom Madrecki of the Consumer Brands Association warned that these tariffs would have immediate consumer impact. “A 50 per cent tariff on a commodity that fundamentally is not available in the US — you can’t really do much with that,” he said, referring to tropical products that cannot be grown domestically.
Broader Trade War Context
The latest tariff threats come as Trump’s trade agenda continues to evolve rapidly. Earlier this week, the president announced a 50 per cent tariff on Brazilian goods, citing concerns about the treatment of former President Jair Bolsonaro and attacks on American social media companies. He has also threatened 35 per cent tariffs on Canadian goods and suggested that blanket tariffs on all trading partners could rise to 20 per cent.
According to trade data, the average applied US tariff rate rose from 2.5 per cent to an estimated 27 per cent between January and April 2025, the highest level in over a century. Following some policy rollbacks, the rate stood at approximately 15.8 per cent as of June.
The administration has collected over £80 billion in customs revenue for the first time in a fiscal year, with Treasury Secretary Scott Bessent projecting total customs revenue could reach £240 billion in 2025.
Diplomatic Efforts Continue
Despite the announcement, both sides have indicated that negotiations will continue until the 1 August deadline. The EU has proposed a “zero for zero” deal eliminating tariffs on industrial goods, including automobiles, though Trump has indicated this proposal falls short of addressing American concerns.
French Trade Minister Laurent Saint-Martin reiterated the EU’s stance during a visit to Indonesia, stating, “We believe that a tariff war is harmful for everyone. We must continue the work of dialogue and negotiation with the US.”
As the deadline approaches, businesses on both sides of the Atlantic are preparing for potential disruptions to supply chains that have been carefully constructed over decades of free trade. The ultimate impact will depend on whether diplomats can find common ground in the coming weeks or whether the world’s largest trading relationships will face their most significant test in generations.
