Stronger-than-forecast UK Consumer Price Index (CPI) figures and another rise in government debt left the British Pound (GBP) fluctuating against the US Dollar (USD) on Wednesday. After touching a session low of 1.3364, GBP/USD recovered towards 1.3375. The pair continues to consolidate the gains of recent days, having been unable to establish itself above 1.3400 on Tuesday.

September’s UK Consumer Price Index (CPI) increased by 0.4%, National Statistics reported. Although slightly below August’s 0.5% rise, the reading exceeded market forecasts of 0.3%. On a year-on-year (Y-o-Y) basis, CPI growth quickened from 3.1% in August to 3.5%, beating the market consensus of 3.4%.
Excluding volatile food and energy prices, core CPI also surpassed expectations. The Y-o-Y rate reached 2.8%, compared with a market consensus of 2.7% and August’s 2.6% increase.
Released alongside the inflation figures, National Statistics data showed UK Public Sector Net Borrowing climbing from GBP 17.25 billion in August to GBP 24.52 billion in September. Renewed concerns over the UK’s high public debt may have followed, weighing somewhat on the Pound.
Tuesday’s unexpected fall in the ILO Unemployment Rate to its lowest in more than a year preceded Wednesday’s releases. Together with last week’s encouraging Gross Domestic Product (GDP) figures, the data have reinforced market expectations of a possible Bank of England interest rate increase at its 5 November meeting.
Following five days of selling, the Dollar Index (DXY) is recouping part of its losses, with the US Dollar modestly firmer on Wednesday. A pause at next week’s Federal Reserve (Fed) monetary policy meeting is already priced in. Meanwhile, concerns over high oil prices, against a backdrop of uncertainty surrounding the Middle East conflict, continue to draw safe-haven flows into the Greenback.
Published monthly by the Office for National Statistics, the United Kingdom (UK) Consumer Price Index (CPI) tracks consumer price inflation: the pace at which prices for goods and services purchased by households increase or decrease. Compiled to international standards, it is the measure used for the government’s inflation target. The YoY figure compares prices in the reference month with those a year earlier. A higher reading is generally regarded as bullish for the Pound Sterling (GBP), whereas a lower reading is regarded as bearish.

Headline Consumer Price Index (CPI) inflation is subject to the Bank of England’s target of around 2%, making the monthly release important for traders. Rising inflation points to interest rates increasing sooner and more rapidly, or to the BOE scaling back bond purchases, thereby restricting the supply of pounds. By contrast, a slowdown in price growth signals looser monetary policy. An above-forecast reading generally supports GBP.
Published by National Statistics, Public Sector Net Borrowing measures the amount of new debt held by UK governments, representing the financial deficit in the UK national accounts. A negative net borrowing figure generally indicates a surplus in the UK accounts, which should support GBP. As a deficit is generally unfavourable for the economy, an increase in net borrowing is regarded as negative, or bearish, for GBP.
