UK CPI set to grow at stable 2.2% in August ahead of BoE meeting

• The United Kingdom's CPI is foreseen to grow at stable pace of 2.2% in the year to August.
• The Bank of England will announce its monetary policy decision on Thursday.
• The Pound Sterling is technically bullish and could surpass the 1.3300 mark.

The United Kingdom (UK) Office for National Statistics (ONS) will release August Consumer Price Index (CPI) figures on Wednesday. Inflation, as measured by the CPI, is one of the main factors on which the Bank of England (BoE) bases its monetary policy decision, meaning the data is considered a major mover of the Pound Sterling (GBP). 

The BoE met in August and decided to trim the benchmark interest rate by 25 basis points (bps) to 5%, a decision supported by a slim majority of 5 out of the 9 voting members of the Monetary Policy Committee (MPC). The widely anticipated announcement had a negative impact on the GBP, which entered a selling spiral against the US Dollar, resulting in the GBP/USD pair bottoming at 1.2664 a couple of days after the event.

What to expect from the next UK inflation report?

The UK CPI is expected to have risen at an annual pace of 2.2% in August, matching the July print. The core annual reading is foreseen at 3.5%, higher than the previous 3.3%. Finally, the monthly index is expected to grow by 0.3% after falling by 0.2% in July. 

It is worth adding that the BoE will announce its monetary policy on Thursday and that inflation levels could affect policymakers' decision. Ahead of the announcement, financial markets anticipate officials will keep rates on hold before adopting a more aggressive stance from November on. The central bank anticipated that inflation could reach 2.75% in the upcoming months before gradually declining and even falling below the 2% goal in 2025. 

Meanwhile, the BoE released a quarterly survey on public inflation expectations last week, which showed that inflation for the next 12 months is expected to fall to 2.7%, the lowest in three years. However, the 5-year perspective ticked higher, to 3.2% from 3.1% in May. The figures support the case for on-hold rates, and so will the expected CPI outcome.

Finally, it is worth noting that the UK entered a technical recession in the last quarter of 2023. Ever since the economy has recovered, but growth is sluggish, and the risk of another setback remains. 

In such a scenario, a mild deviation from the expected figures could have a limited impact on Pound Sterling. Higher than-anticipated readings could cool down hopes for aggressive rate cuts, but the path is clear. The BoE will reduce interest rates and there is no room for hikes. Even further, market participants don't expect the BoE to deliver a cut when it meets later this week, which would likely reduce the potential impact on the currency.

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

The UK Office for National Statistics will release August CPI data figures on Wednesday at 06:00 GMT. Before analysing potential scenarios, there's still one more thing to consider: Despite headline inflation hovering around the central bank's goal, services inflation has remained quite hot and above 5% for most of the year, more than doubling the headline one. 

As said, a modest uptick in inflation could be seen as modest rate cuts coming, but it will not surprise investors enough to consider the opposite scenario. On the contrary, a lower-than-anticipated outcome with easing services inflation should fuel hopes for more aggressive rate cuts and put the Pound Sterling under strong selling pressure. 

Valeria Bednarik, FXStreet's Chief Analyst, notes: "The GBP/USD pair is heading into the event trading above the 1.3200 mark, and not far from the multi-month high at 1.3265 posted in August. Most of the pair's strength is the result of the broad US Dollar's weakness, as the Federal Reserve (Fed) is expected to deliver its first rate cut on Wednesday. The Fed's event is likely to overshadow UK CPI release, as market players would wait until after the US central bank announcement to take positions."

Technically speaking, Bednarik adds: "GBP/USD is bullish according to technical readings in the daily chart. A break through the aforementioned August high could lead to a quick test of the 1.3300 mark, while once beyond the latter, the rally can continue towards 1.3360. A daily close above the 1.3300 threshold would support the case for a steady advance in the days to come. On the other hand, the pair would need to slip below the 1.3140 region to put the bullish case at risk. In that case, the next level to watch and the potential bearish target comes at 1.3000."
