The UK economy has delivered a robust performance in the first quarter of 2026, with preliminary GDP growth of +0.6% quarter-on-quarter (q/q) and +1.1% year-on-year (y/y). This solid showing is a testament to the economy's resilience, despite the headwinds posed by rising energy prices. However, as I will argue, this positive momentum may be short-lived, with the real test for the UK economy yet to come in the form of the US-Iran conflict.
A Strong Start, But What Lies Ahead?
The UK economy's performance in Q1 is indeed impressive, with services output leading the charge. The services sector, which accounts for a significant portion of the UK economy, grew by 0.8% in Q1 2026, a sharp contrast to the 0.2% growth in Q4 2025. This is particularly noteworthy, as it suggests that the economy is not only bouncing back but also expanding. Moreover, non-consumer-facing services, or business-facing services, grew by 0.7%, while consumer-facing services grew by 0.8%, indicating a balanced and robust growth across different sectors.
Household consumption also showed a notable increase in the first quarter (+0.35%), a marked improvement from the final quarter of last year (+0.07%). This is a positive sign, as it suggests that consumers are feeling more confident and willing to spend. However, as I will argue, this may be a temporary boost, and the real test for the economy will come in the form of the US-Iran conflict.
The US-Iran Conflict: A Looming Threat
The US-Iran conflict has the potential to disrupt global supply chains and markets, and the UK economy is not immune to this. The conflict has already led to a rise in energy prices, which has had a knock-on effect on the cost of living and business operations. As the conflict escalates, it is likely that the UK economy will face further challenges, such as reduced trade and investment, and increased uncertainty.
In my opinion, the real test for the UK economy will come in the second quarter of 2026, as the effects of the conflict become more pronounced. The economy may have enjoyed a period of resilience and solid performance in Q1, but the real challenge begins now. The UK government and central bank will need to take proactive measures to mitigate the impact of the conflict and support the economy, such as providing financial support to businesses and households, and implementing policies to boost trade and investment.
Conclusion: A Moment of Resilience, But What Lies Ahead?
The UK economy has delivered a strong performance in Q1, but the real test is yet to come. The US-Iran conflict has the potential to disrupt global markets and supply chains, and the UK economy is not immune to this. As I have argued, the economy may have enjoyed a period of resilience and solid performance in Q1, but the real challenge begins now. The UK government and central bank will need to take proactive measures to mitigate the impact of the conflict and support the economy, and the future of the UK economy hangs in the balance.
