The United Kingdom (UK) Office for National Statistics (ONS) will publish the high-impact Consumer Price Index (CPI) data for August on Wednesday at 06:00 GMT.
The UK CPI inflation report could significantly impact the direction of the Bank of England’s (BoE) interest rate move and the Pound Sterling (GBP) just ahead of Thursday’s Bank of England (BoE) meeting to decide on interest rates.
The UK Consumer Price Index is forecast to rise 3.9% year-over-year (YoY) in August, following a 3.8% increase in July.
While the reading is set to meet the BoE’s projection, it will also come in almost double its 2.0% target.
Core CPI inflation, which excludes energy, food, alcohol, and tobacco prices, is expected to fall to 3.6% YoY in August from 3.8% in July.
According to a Bloomberg survey of economists, official data is expected to show that service inflation remained elevated well above the BoE’s 2% target, seen at 4.8% YoY in August vs. 5.0% in July.
Meanwhile, the British monthly CPI is expected to rise by 0.3% in the same period, after having increased by 0.1% in July.
“We expect a mixed CPI print, with core coming in below consensus, but in line with Monetary Policy Report (MPR) projections; and headline at 3.9% YoY to be a tick above both market and BoE forecasts,“ TD Securities analysts said in a research note ahead of the data release.
The expected slight uptick in British inflation and a cooling labor market could dictate the BoE’s path forward on interest rates beyond the anticipated September pause.
The latest labor data published by the Office for National Statistics showed annual growth in regular earnings, excluding bonuses, slowed to 4.8% in the three months to July from 5% previously, while the Unemployment Rate remained unchanged at 4.7%, both readings matching the analysts’ estimates.
Meanwhile, a strong majority of the economists polled by Reuters pencilled in a 25-basis-point cut next quarter, with increased bets for a rate reduction in November.
At its August monetary policy meeting, the BoE lowered the benchmark rate to 4%, but after an unprecedented second round of voting that ended with a 5-4 split in favor of such a move.
The central bank repeated its guidance about "a gradual and careful approach" to further cuts in borrowing costs but added that "the restrictiveness of monetary policy had fallen as Bank Rate had been reduced.”
Therefore, a hotter-than-expected headline inflation data would pour cold water on expectations of any rate cuts this year. In such a case, the Pound Sterling will receive the much-needed boost, driving GBP/USD toward the 1.3700 barrier. Conversely, an unexpected slowdown in annual CPI could ramp up the odds of a November rate cut, which could weigh heavily on the pair.
Dhwani Mehta, Asian Session Lead Analyst at FXStreet, offers a brief technical outlook for the major and explains: “GBP/USD is sitting at the highest level in two months above 1.3600, with the 14-day Relative Strength Index (RSI) momentum indicator pointing north above the 50 level.”
“The pair needs acceptance above the 1.3650 psychological barrier to extend the uptrend toward the 1.3700 threshold. The next topside target is aligned at the July high of 1.3789. Conversely, the immediate support is seen at around the 1.3550 level, below which the 21-day Simple Moving Average (SMA) at 1.3506 could be challenged. Further down, the last line of defense for buyers is seen at the confluence zone of the 50-day SMA and the 100-day SMA at around 1.3470,” Dhwani adds.
The United Kingdom (UK) Consumer Price Index (CPI), released by the Office for National Statistics on a monthly basis, is a measure of consumer price inflation – the rate at which the prices of goods and services bought by households rise or fall – produced to international standards. It is the inflation measure used in the government’s target. The YoY reading compares prices in the reference month to a year earlier. Generally, a high reading is seen as bullish for the Pound Sterling (GBP), while a low reading is seen as bearish.

The Bank of England is tasked with keeping inflation, as measured by the headline Consumer Price Index (CPI) at around 2%, giving the monthly release its importance. An increase in inflation implies a quicker and sooner increase of interest rates or the reduction of bond-buying by the BOE, which means squeezing the supply of pounds. Conversely, a drop in the pace of price rises indicates looser monetary policy. A higher-than-expected result tends to be GBP bullish.
Inflation measures the rise in the price of a representative basket of goods and services. Headline inflation is usually expressed as a percentage change on a month-on-month (MoM) and year-on-year (YoY) basis. Core inflation excludes more volatile elements such as food and fuel which can fluctuate because of geopolitical and seasonal factors. Core inflation is the figure economists focus on and is the level targeted by central banks, which are mandated to keep inflation at a manageable level, usually around 2%.
The Consumer Price Index (CPI) measures the change in prices of a basket of goods and services over a period of time. It is usually expressed as a percentage change on a month-on-month (MoM) and year-on-year (YoY) basis. Core CPI is the figure targeted by central banks as it excludes volatile food and fuel inputs. When Core CPI rises above 2% it usually results in higher interest rates and vice versa when it falls below 2%. Since higher interest rates are positive for a currency, higher inflation usually results in a stronger currency. The opposite is true when inflation falls.
Although it may seem counter-intuitive, high inflation in a country pushes up the value of its currency and vice versa for lower inflation. This is because the central bank will normally raise interest rates to combat the higher inflation, which attract more global capital inflows from investors looking for a lucrative place to park their money.
Formerly, Gold was the asset investors turned to in times of high inflation because it preserved its value, and whilst investors will often still buy Gold for its safe-haven properties in times of extreme market turmoil, this is not the case most of the time. This is because when inflation is high, central banks will put up interest rates to combat it. Higher interest rates are negative for Gold because they increase the opportunity-cost of holding Gold vis-a-vis an interest-bearing asset or placing the money in a cash deposit account. On the flipside, lower inflation tends to be positive for Gold as it brings interest rates down, making the bright metal a more viable investment alternative.
