BritishAmerican Business (BAB) has today released its six-month review of the

UK-US Economic Prosperity Deal (EPD), providing the most detailed independent assessment on how much progress has been made since the General Terms of the agreement were signed on May 8th, 2025.


The analysis finds that while the EPD has delivered meaningful advances in certain areas, specifically technology and life sciences, progress across the wider agenda has been inconsistent, with several commitments still lacking clarity, timelines or implementation.


Among the most positive developments are the recent pharmaceuticals agreement, which secures some tariff exemptions and highlights future regulatory collaboration, and the Technology Prosperity Deal, which provides a framework for future cooperation in AI, civil nuclear energy and other advanced technologies. 


The review also finds that large parts of the EPD remain unresolved, including those related to steel and aluminium, non-tariff barrier reform, digital trade, and other sectors still under Section 232 investigation. Additionally, automotive and agricultural businesses continue to face uncertainty over how key tariff arrangements will be implemented.


While the continuation of the 10 per cent reciprocal tariff on UK goods remains a challenge for exporters, BAB remains hopeful that continued engagement between the negotiating teams will lead to greater alignment on non-tariff issues.


BritishAmerican Business CEO Duncan Edwards said:


“The Economic Prosperity Deal was always going to require sustained political attention to deliver results. While there have been meaningful steps forward, especially in tech and pharma, we cannot ignore the fact that large parts of the deal have yet to translate into measurable improvements for businesses. We fully acknowledge the positive intentions of both governments and understand that the issues involved are complex and politically sensitive. We will continue to give our full support to the process in any way that we can.”


As the leading transatlantic business organisation, BAB will continue to monitor and evaluate every commitment in the EPD. BAB urges both governments to ensure progress remains on track and helps deliver tangible benefits for transatlantic businesses.
