GBP/USD faces a tougher second half of 2026 as central bank expectations shift against sterling. As of the second half outlook, the British pound has already fallen around 2% in Q2 while UK growth weakens and U.S. economic data remains more resilient. The result is a widening policy contrast between the Federal Reserve and the Bank of England, with potential consequences for currency positioning, gilt yields and dollar demand.
Fiona Cincotta, StoneX Senior Market Analyst, tracks global macro and foreign exchange markets through central bank decisions, economic data and political risk. Her perspective is directly relevant to GBP/USD because the pound outlook now depends on how investors price the gap between Federal Reserve tightening expectations and Bank of England restraint.
Key Themes
GBP/USD has fallen around 2% in Q2 as the pound faces a more challenging second half of 2026.
UK growth is weakening, business activity has contracted for two straight months and the labor market is cooling.
The Federal Reserve and the Bank of England policy gap could become the biggest driver of GBP/USD in the months ahead.
GBP/USD weakness is being reinforced by a stronger U.S. policy backdrop and a more resilient U.S. economy. Cincotta notes that "across the Atlantic the picture looks very different" and adds that "the US economy is surprisingly resilient". Elevated U.S. inflation and expectations for further Federal Reserve rate hikes may keep the U.S. dollar supported against sterling. For investors, the key issue is whether GBP/USD continues to price a wider yield advantage in favor of the dollar.
Bank Of England Restraint Leaves Sterling Exposed
Sterling is losing support as softer UK inflation reduces pressure on the Bank of England to tighten policy aggressively. Cincotta states that "UK inflation came in below expectations" and that the Bank of England "may not need to raise rates as aggressively as investors previously thought". As a result, the British pound faces a weaker domestic rate outlook just as the Federal Reserve appears more hawkish. This divergence could make GBP/USD more sensitive to incoming UK growth data, U.S. inflation readings and any shift in central bank communication.
