This section below was published at 23:15 GMT on Tuesday as a preview of the UK inflation data.

  • The high-impact UK CPI data will be released by the Office for National Statistics on Wednesday.
  • Headline and core annual inflation from the United Kingdom are set to fall, while monthly CPI is expected to rebound.
  • The UK CPI report could significantly influence the BoE policy outlook, impacting the Pound Sterling.

With increased bets for an interest cut by the Bank of England (BoE) as early as April, the all-important Consumer Price Index (CPI) data from the United Kingdom (UK) will be closely scrutinized for gauging the timing of the BoE policy pivot and its impact on the Pound Sterling.

The Office for National Statistics (ONS) will release the UK inflation data at 07:00 GMT on Wednesday.

What to expect from the next UK inflation report?

The headline annual UK Consumer Price Index is seen growing by 3.8% in December, a modest slowdown from November’s 3.9% increase. The reading would be its lowest since September 2021, but still almost double the BoE’s 2.0% target.

The Core CPI inflation is seen falling further to 4.9% YoY in December, compared with a 5.1% growth recorded in November. Meanwhile, the British monthly CPI is expected to jump 0.2% after falling 0.2% in November.

Analysts at TD Securities (TDS) cited key reasons behind the likely easing in the headline inflation data, noting that “We don't expect a rebound from the weak Nov report, and instead look for more weakness in Dec. A rise in tobacco duty adds some upside pressure on the headline, but softness in leisure and travel should support a decent fall in services to 6.0% YoY— a notable 0.9 ppts below the MPC. This should support a dovish pivot soon from the MPC in Feb, but cuts likely won't come until May.”

At a hearing of the Treasury committee earlier this month, BoE Governor Andrew Bailey said he hoped the recent fall in the cost of mortgages would continue. Bailey refrained from commenting on the monetary policy outlook but said, “let’s just take the market for a moment – obviously that is feeding through into mortgage costs and I hope that is something that continues.”

After the UK central bank held the policy rate at 5.25% at its December meeting, Governor Bailey pushed back against speculation in the financial markets that the interest rates would soon be reduced, stressing that the fight to bring inflation down to 2% is “hard work.”

A surprise fall in inflation in November, however, raised hopes that the BoE would begin cutting interest rates sooner than expected. The ONS said that falling petrol prices were largely behind the surprise drop in inflation last month, alongside easing food and household goods price inflation.

In the quarter to November, UK wages grew at the slowest pace in almost a year, adding to signs of easing inflationary pressures and BoE’s worries. Average Earnings Excluding Bonus in the UK rose 6.6% 3M YoY in November, slowing from October’s 7.2% increase. 

Meanwhile, Britain's Gross Domestic Product (GDP) expanded by 0.3% in November after October’s 0.3% decline. But the economy remains at high risk of slipping into a recession as households continue to bear the burden of high energy bills and borrowing costs.

Against this backdrop, the upcoming UK inflation data could help estimate the pace and timing of the central bank’s interest rate cuts this year, which could have a significant impact on the value of the Pound Sterling.

When will the UK Consumer Price Index report be released and how could it affect GBP/USD?

The UK CPI data will be published on Wednesday at 07:00 GMT. The Pound Sterling is correcting from two-week highs of 1.2786 against the US Dollar in the run-up to the United Kingdom’s inflation showdown. The US Dollar is regaining its safe-haven status amid an escalation of geopolitical tensions in the Middle East.

An unexpected uptick in the headline and core inflation data could pour cold water on expectations of a BoE rate cut as early as April, providing the much-needed lift to the Pound Sterling. In such a case, GBP/USD could revert toward the 1.2785 region. Conversely, GBP/USD could extend its correction toward 1.2600 if the UK CPI data shows a rapid fall in inflation and affirms BoE April rate cut bets.

Dhwani Mehta, Asian Session Lead Analyst at FXStreet, offers a brief technical outlook for the major and explains: “The GBP/USD pair has breached the 21-day Simple Moving Average (SMA) at 1.2712, as the downside correction unfolds. The 14-day Relative Strength Index (RSI) is piercing the midline from above, suggesting more pain ahead of the Pound Sterling.”

“A sustained move below the ascending 50-day SMA at 1.2611 could intensify selling pressure on the Pound Sterling. The next downside targets are seen at the critical 200-day SMA at 1.2548 and the 1.2500 round level. Alternatively, any recovery in GBP/USD will need acceptance above the 21-day SMA support-turned-resistance at 1.2712, above which doors will reopen for a test of the two-week high of 1.2786,” Dhwani adds.

Inflation FAQs

What is inflation?

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%.

What is the Consumer Price Index (CPI)?

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.

What is the impact of inflation on foreign exchange?

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.

How does inflation influence the price of Gold?

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.

AUD/USD pulls back from monthly high but holds above 0.7000

AUD/USD retreats from the monthly high set earlier this Thursday, sliding back to 0.7000 during the Asian session as a further escalation of tensions in the Middle East undermines the risk-sensitive Aussie. However, recent hawkish comments from RBA officials could support the Australian Dollar. Furthermore, the prevailing US Dollar selling bias, despite Fed hike bets and geopolitical uncertainties, could limit losses for the pair.

USD/JPY declines to a one-week low; eyes trading range support near 157.50 on weaker USD

USD/JPY drops to a one-week low during Thursday’s Asian session, with bears now awaiting a break below multi-week range support near mid-157.00s before placing fresh bets amid a broadly weaker US Dollar. Despite bets for a December Fed rate hike and Middle East jitters, the recent decline in US bond yields keeps USD depressed near a three-week low. Moreover, hawkish BoJ expectations and intervention risks underpin the Japanese Yen, further weighing on the currency pair.

Gold remains offered just above $4,000

Gold prices resume their decline on Thursday, easing toward the area of two-month lows around $4,050 per troy ounce. Higher crude oil prices have reignited speculation of further tightening by the Fed, supporting the US Dollar and weighing on the precious metal.

UK inflation as measured by the CPI accelerated to 3.5% YoY in September, up from 3.1% in August, according to the Office for National Statistics. This is the highest level since October 2025, exceeding economists' expectations of 3.4% and pushing inflation further from the BoE's 2% target.

What November 3 means for the Fed's rate path and the US Dollar
