Introduction to the British Pound’s Performance
The British pound has experienced a significant rally against the US dollar in 2025, reaching multi-year highs. However, it lost ground against the euro, resulting in a volatile year for currency markets. Economists are now looking ahead to 2026, anticipating potential triggers for sterling weakness, including weak UK growth, further interest rate cuts from the Bank of England, and ongoing political risk from UK fiscal policies.
Key Takeaways
- Currency traders are focused on the Bank of England’s next moves, as UK interest rate cuts could weaken sterling against the dollar and euro.
- Political risk, with new threats to the UK prime minister’s leadership, could lead to continued sterling volatility.
- Against the dollar and euro, the pound remains below levels seen before the vote to leave the European Union in 2016.
2026 British Pound Forecast: At a Glance
The forecast for the British pound in 2026 is nuanced, with several factors at play.
- GBP vs USD: Modest upside as rate differentials narrow, according to Morningstar analysts.
- GBP vs EUR: Performance tied closely to UK economic growth in early 2026.
- Key Risks: Bank of England rate cuts, renewed political instability.
- Key Support: Fading fiscal risk premium after the Autumn Budget.
How the Pound Has Performed Against the Dollar and Euro in 2025
In 2025, the strengthening pound lowered returns on dollar assets and flattered assets denominated in euros. The GBP/USD exchange rate is now back to levels last seen in late 2021, with one pound currently buying USD 1.35. This is a far cry from autumn 2022, when the pound slumped during Liz Truss’s short-lived run as UK prime minister. The pound is also lower against the euro than it was before the Brexit vote in 2016, weakening from EUR 1.21 to EUR 1.15 in 2025.
Factors Influencing the Pound’s Performance
Strong economic growth in countries like Portugal, Spain, Greece, and Italy, along with ambitious defense spending plans by Germany, have boosted the attractiveness of holding euro assets. The euro has also benefited from the shift away from US assets in the trade war era. However, according to Hong Cheng, head of fixed income and currency research at Morningstar Wealth, the euro is not yet in a position to challenge the dollar’s status.
Bank of England Holds the Key to GBP Performance in 2026
A strong year for the pound against the dollar came despite a period when UK monetary policy was being loosened, with the Bank of England cutting rates four times in 2025. Lower interest rates reduce the attractiveness of holding a country’s currency and assets because higher yields can be found elsewhere. However, it also depends on interest rate moves made by other central banks, such as the Federal Reserve. With sluggish economic growth and a weakening labor market, the Bank of England could play a key role by lowering interest rates further to stimulate economic activity amid falling inflation.
UK Political Risk Could Still Weaken Sterling
Some experts point to domestic factors as influencing the pound’s next move. While the Autumn Budget answered certain questions about the government’s fiscal plans, political uncertainty is still a live issue. With at least two separate political revolts hitting the UK prime minister, Keir Starmer, in 2025, many anticipate 2026 bringing further turbulence as internal Labour Party politics come back to the fore and the May local elections potentially result in a formal leadership challenge. This could lead to a selloff in sterling, as it did at key points in 2025 when market anxiety over the government’s economic plans was at its highest.
Conclusion
In conclusion, the British pound’s performance in 2026 will be influenced by a combination of factors, including the Bank of England’s interest rate decisions, UK economic growth, and political risk. While there are potential triggers for sterling weakness, such as weak UK growth and ongoing political instability, the pound may also experience modest upside against the US dollar as rate differentials narrow. As the UK navigates its economic and political landscape, investors and currency traders will be closely watching the British pound’s movements, anticipating how it will perform against the dollar and euro in the coming year.
