Unexpectedly strong UK growth data is challenging forecasts of a pound sterling decline, raising the prospect that the currency could finish 2026 higher against both the euro and the US dollar if key risks are avoided
Recent UK economic data has shifted the outlook for pound sterling, with stronger-than-expected growth in the second quarter of 2026 prompting some analysts to question the widely held view that the currency will weaken against the euro and US dollar in the second half of the year. While many institutional forecasts remain cautious, the latest figures suggest the UK economy is proving more resilient than anticipated, opening the door to a potential upside surprise for the pound.
Market sentiment has been shaped by concerns over fiscal policy, political uncertainty, and expectations that the Bank of England will hold off on further rate hikes. However, the persistence of negative positioning may itself create conditions for a rebound if the economy continues to outperform and fiscal risks are managed carefully.
Growth Data Defies Expectations
The UK economy expanded by 0.4% in the second quarter of 2026, with June alone posting a 0.3% increase-both figures exceeding consensus forecasts and the Bank of England's own projections. Annual growth reached 1.2%, and the first quarter had already seen a 0.6% rise. This momentum is reflected in other indicators: the July flash composite PMI climbed to 52.1, June retail sales outperformed expectations, and recent labour market data indicate that job losses have stabilised after two years of weakness.
Historically, the UK economy has tended to slow in the second half of the year, but so far in 2026, this seasonal pattern has not materialised. Business investment rose by 1.7% quarter-on-quarter in Q2, and some economists now see the risks to growth as tilted to the upside, especially if investment in artificial intelligence infrastructure continues to provide support. Inflation has surprised on the downside for three consecutive months, giving the Bank of England more flexibility, though the annual rate remains at 2.8%-still above the 2.0% target. The stabilisation of the labour market may also encourage some Monetary Policy Committee members to consider further rate increases if inflation pressures re-emerge.
Fiscal Policy and Political Risks
Much of the market's caution towards pound sterling is rooted in concerns about the upcoming UK budget, scheduled for late October. While the fiscal environment remains challenging, Prime Minister Andy Burnham has so far demonstrated a cautious approach, favouring targeted measures such as a VAT cut on electricity bills, a bus fare cap, and business rates relief for pubs, rather than large-scale spending. When pressed on major commitments, Burnham has consistently avoided unfunded promises, and his government is acutely aware of the risks that fiscal missteps could pose to both bond and currency markets.
With the institutional community braced for a difficult budget, a fiscally neutral outcome could prompt a positive repricing of the pound if it reduces perceived risk. The presence of a Treasury acting as a brake on spending, combined with market sensitivity to fiscal signals, means that even a modestly prudent budget could help support sterling into year-end.
Competing Forecasts and Key Risks
Despite the improved data, many banks and analysts-including HSBC and Rabobank-continue to forecast a weaker pound against both the euro and the dollar, citing the risk of economic slowdown and political uncertainty. However, some, such as Lloyds Bank, now see scope for the pound to strengthen against the euro by the end of 2026. The main risks to a stronger pound remain a potential fiscal policy error in October, a renewed energy price shock that reignites inflation, or a global risk event that undermines sentiment towards UK assets.
For now, the combination of resilient growth, stabilising inflation, and cautious fiscal management suggests that the pound could outperform the downbeat consensus-provided these key risks do not materialise.
According to the Office for National Statistics, the pound sterling traded at 1.16 against the euro and 1.29 against the US dollar at the end of June 2026, both levels broadly unchanged from the start of the year. The Bank of England's policy rate remained at 4.75% in July, with inflation at 2.8% year-on-year. These figures highlight the relative stability of the pound despite ongoing uncertainty in the broader economic and political environment.
Fiscal policy plays a central role in shaping currency outcomes, especially in economies where government borrowing and spending are closely watched by investors. In the UK, the experience of rapid market reactions to fiscal announcements in recent years has reinforced the importance of credible, transparent budgeting. Even small shifts in fiscal stance can influence perceptions of risk and, by extension, the value of the pound. As the October budget approaches, the interplay between economic data, political decisions, and market expectations will remain critical for sterling's direction.
