Ipek Ozkardeskaya, senior analyst at Swissquote, said: "Finally some data! Economic data remains scarce due to the ongoing US government shutdown, but the Bureau of Labor Statistics decided to publish September CPI figures today to give policymakers and investors some direction ahead of next week’s decision.
"Both headline and core inflation are expected to land around 3.1% YoY for September, and some analysts warn CPI could rise toward 3.5% in the coming months amid tariff-driven pressures. That’s well above the Fed’s 2% target, but markets broadly believe the central bank will tolerate higher inflation to avoid an economic meltdown.
"Even so, inflation remains an issue. Today’s numbers are unlikely to be a game-changer if they align with the 3% expectation. A softer print could fuel speculation of a third rate cut in December, boosting risk appetite while dragging US yields and the dollar lower. Conversely, a stronger CPI could trigger a reassessment of dovish expectations and raise questions about whether major indices deserve to keep pushing into uncharted highs."
The US CPI data for September is due at 1330 BST.
On home shores, figures from the Office for National Statistics showed that retail sales jumped in the last quarter, as the fine weather boosted demand for summer clothing.
The quantity of goods bought was estimated to have risen 0.9% in the three months to September, the highest level since summer 2022.
Sales volumes rose by 0.5% in September, following an upwardly-revised 0.6% increase in August.
Analysts had been expecting a 0.2% dip last month.
ONS senior statistician Hannah Finselbach said: "Retail sales rose quite strongly in the latest quarter and were at their highest level since summer 2022. Although food stores saw very little growth, good weather in July and August boosted sales of clothing, while online retailing also did well.
"Retail sales also grew over the month of September, with tech stores seeing a notable rise in sales, while online jewellers reported strong demand for gold."
