The Dow Jones index yielded 0.02%, the technology-dominated Nasdaq gleaned 0.32% after initially losing up to 1% and the S&P 500 0.17% around 3:00 p.m. GMT.

Inflation remained strong in the United States in January, slowing less than expected over one year and even accelerating over the month, for the first time since October, according to the CPI index published on Tuesday.

Consumer prices increased by 6.4% year on year, against 6.5% the previous month.

This is worse than the 6.2% that was expected.

And over just one month, the rise in prices accelerated to 0.5%, after +0.1% in December (revised figure).

Core inflation (excluding food and energy) is also a little more persistent than expected at 0.4% over the month against 0.3% expected.

Over one year, food prices continued to rise by 10.1% and those of services even accelerated to +7.2% against +7% in December.

"For members of the Fed, this slow decline in inflation only justifies the idea that rates should be kept higher for longer," said Rubeela Farooqi, chief economist for HFE.

"Policymakers still have work to do to bring inflation back towards the target (of 2%) and are likely to continue raising rates and maintain tight policy for some time," the analyst added.

"Inflation is a tenacious adversary," summed up Neil Saunders of Global Data, pointing out that it was "much more persistent than we would like".

“There is really a risk that 2023 will be another year dominated by rising prices,” warned the expert.

Other more optimistic economists, such as Chris Low of FHN Financial, saw "good news" in the fact that inflation had nevertheless "marked a turning point".
