The Pound Sterling (GBP) gains against its major peers on Wednesday after the United Kingdom's (UK) Office for National Statistics (ONS) has reported that inflation grew at a faster-than-projected pace in December.
UK headline inflation rose to 3.4% year-on-year, faster than estimates of 3.3% and the November reading of 3.2%. On a monthly basis, headline CPI grew at an expected pace of 0.4% after contracting by 0.2% in November.
The UK core CPI – which strips off volatile components such as food, energy, alcohol, and tobacco – rose at a steady pace of 3.2% year-on-year (YoY), as expected.
Meanwhile, inflation in the services sector, which is closely tracked by Bank of England (BoE) officials, accelerated to 4.5% YoY from the prior reading of 4.4%.
Signs of price pressures remaining sticky are expected to weigh on market expectations for interest rate cuts by the BoE in the near term. In the December policy meeting, the BoE guided that the monetary policy will remain on a “gradual downward” path.
Going forward, investors will focus on the UK Retail Sales data for December and the preliminary S&P Global Purchasing Managers’ Index (PMI) data for January. Both indicators will be releasedon Friday.

GBP/USD trades broadly sideways near 1.3440 at the time of writing. Price holds marginally above the 20-Exponential Moving Average (EMA) at 1.3429, which has flattened after a steady climb, signaling consolidation. A sustained close above the 20-day EMA would keep the near-term bias tilted to the upside.
The 14-day Relative Strength Index (RSI) at 53 (neutral) shows a slight improvement in momentum. Measured from the 1.3789 high to the 1.3006 low, any rebound would confront the 61.8% retracement at 1.3490, while the 50% retracement at 1.3397 is a pivotal threshold.
A push through 60 by the RSI would strengthen bullish traction, whereas a dip under 50 would reassert bearish pressure. A daily close above the retracement resistance would extend the rebound, while a break back under the 20 EMA could revive the broader pullback.

The Pound Sterling (GBP) is the oldest currency in the world (886 AD) and the official currency of the United Kingdom. It is the fourth most traded unit for foreign exchange (FX) in the world, accounting for 12% of all transactions, averaging $630 billion a day, according to 2022 data. Its key trading pairs are GBP/USD, also known as ‘Cable’, which accounts for 11% of FX, GBP/JPY, or the ‘Dragon’ as it is known by traders (3%), and EUR/GBP (2%). The Pound Sterling is issued by the Bank of England (BoE).
The single most important factor influencing the value of the Pound Sterling is monetary policy decided by the Bank of England. The BoE bases its decisions on whether it has achieved its primary goal of “price stability” – a steady inflation rate of around 2%. Its primary tool for achieving this is the adjustment of interest rates. When inflation is too high, the BoE will try to rein it in by raising interest rates, making it more expensive for people and businesses to access credit. This is generally positive for GBP, as higher interest rates make the UK a more attractive place for global investors to park their money. When inflation falls too low it is a sign economic growth is slowing. In this scenario, the BoE will consider lowering interest rates to cheapen credit so businesses will borrow more to invest in growth-generating projects.
Data releases gauge the health of the economy and can impact the value of the Pound Sterling. Indicators such as GDP, Manufacturing and Services PMIs, and employment can all influence the direction of the GBP. A strong economy is good for Sterling. Not only does it attract more foreign investment but it may encourage the BoE to put up interest rates, which will directly strengthen GBP. Otherwise, if economic data is weak, the Pound Sterling is likely to fall.
Another significant data release for the Pound Sterling is the Trade Balance. This indicator measures the difference between what a country earns from its exports and what it spends on imports over a given period. If a country produces highly sought-after exports, its currency will benefit purely from the extra demand created from foreign buyers seeking to purchase these goods. Therefore, a positive net Trade Balance strengthens a currency and vice versa for a negative balance.
