Main GBP drivers
- Bank of England interest-rate expectations
- Inflation and wage growth
- Economic growth
- Government fiscal policy
- Politics and trade
- Global risk sentiment
1. Interest-rate expectations
Higher expected UK interest rates relative to other countries tend to support sterling, because they increase the return on holding pounds. Markets react to changes in expectations — from data, speeches and Bank of England decisions — more than to the current rate itself.
2. Inflation and wages
UK CPI and wage growth feed directly into rate expectations. A hotter-than-expected inflation print often lifts GBP; a softer one can weaken it.
3. Growth
GDP, PMI surveys and retail sales show the economy's momentum. Strong growth supports the case for higher rates; weakness can weigh on the pound.
4. Fiscal policy
Budgets and borrowing plans can move sterling and UK government bond yields together. Markets watch how credible spending and tax plans look.
5. Politics and trade
Elections, referendums and trade negotiations can cause large moves, especially when outcomes are uncertain.
6. Global risk sentiment
In risk-off periods investors often favour the US dollar, Swiss franc and Japanese yen, which can push GBP/USD and GBP/JPY lower even without UK news.
