The world is shifting rapidly, a reality underscored by the UK chancellor’s remarks—only for events to reinforce that change just hours later. In Westminster, the phrase “the world has changed” has become a common justification for policy adjustments, particularly following the Spring Statement delivered by Rachel Reeves, which introduced shifts in priorities and spending cuts.
One of the key reasons behind this uncertainty is Donald Trump’s return to the White House, bringing with him unpredictable economic and trade policies. His latest move? A sweeping 25% tariff on all imported cars, a decision that has significant implications for the UK. As the second-largest export market for British cars after the EU, the US remains a vital trading partner, making the new tariffs a serious concern for UK manufacturers.
So far, the UK government’s approach has been one of cautious diplomacy—opting for private negotiations while avoiding public confrontation with Trump, wary of provoking his well-known volatility. Behind closed doors, officials have been working tirelessly to secure a UK-US trade deal that could provide some buffer against these sudden economic shifts. However, this situation highlights a broader challenge: uncertainty has become the new certainty in international relations, forcing UK leaders to constantly anticipate and react to potential upheavals.
The Office for Budget Responsibility (OBR), the independent forecaster, has attempted to predict the impact of these changes, though it acknowledges the difficulty of making economic projections in such an unpredictable landscape. Its latest report examines possible outcomes if the US raises tariffs by 20 percentage points, including scenarios where other countries, including the UK, retaliate. The worst-case scenario—where global trading partners reciprocate with their own tariffs—could severely impact the UK’s fiscal plans, undoing the careful economic balancing act that Reeves has been managing.

With Trump’s self-proclaimed “Liberation Day” just around the corner—when a fresh wave of tariffs is expected to be announced—intensive negotiations between the UK and US are in full swing. Reeves has confirmed that talks are ongoing to address tariffs on cars, steel, and other key sectors, stressing that the UK is keen to avoid a full-scale trade war.
As the world continues to evolve unpredictably, UK policymakers remain in a reactive stance, trying to mitigate the fallout of Trump’s economic maneuvers while keeping the country’s financial stability intact.
