The GBP/USD pair is expected to remain sideways, with investors awaiting the United States (US) Consumer Price Index (CPI) data for July in the North American session and the United Kingdom (UK) Q2 Gross Domestic Product (GDP) data on Thursday. Investors expect the US CPI data to have a meaningful impact on Federal Reserve (Fed) interest rate expectations, as comments from Chairman Kevin Warsh in the July policy meeting press conference signaled heightened concerns regarding upside inflation risks. The projections point to a modest month-on-month rebound in both headline and core price pressures, alongside slightly lower annual rates compared with June. On Thursday, the UK Q2 GDP data is expected to arrive lower at 0.4% from 0.6% in the first quarter this year. Below the 20-day EMA, the pair would be exposed to the July 28 low at 1.3273.
