London (AFP) - Stock markets seesawed Friday as data showed a key US inflation indicator easing in December, opening the door for the Federal Reserve to slow its rate-hike campaign.
But the data also showed that consumer spending dipped further, raising concerns about whether the US economy will be able to dodge a recession.
Wall Street's three main indices opened mixed, then pushed higher only to fall back and then turn positive.
In Europe, the three main indices also wobbled in afternoon trading but finished with meagre gains.
Markets had risen the day before after official figures showed the US economy had grown more than expected in the fourth quarter of last year.
Fresh data on Friday showed the Fed's preferred inflation gauge, the personal consumption expenditures (PCE) price index, rising 5.0 percent last month from a year ago.
"The key takeaway from the report is that it showed a continued moderation of inflation pressures," said Briefing.com analyst Patrick O'Hare.
But, he added, consumer prices were "still too high for the Fed's liking...and will keep the Fed in a vigilant, inflation-fighting mode".
Investors hope the Fed, which meets next week, will lift interest rates by just 25 basis points, having slowed its pace of increases last month following four straight bumper hikes aimed at bringing inflation down from multi-decade highs.
The US economy grew 2.9 percent in the fourth quarter of 2022, exceeding analyst estimates with help from resilient consumer spending, which is a key economic driver.
But Friday's data also showed household spending dipped a further 0.2 percent between November and December.
Analysts believe spending is set to slow further in the coming months.
"The latest data offer among the first tangible signs that the economy's main engine is slowing," said Oren Klachkin of Oxford Economics.
While the data did not eliminate recession fears, it nonetheless offered a reason for optimism that the US central bank will manage to lower inflation without tipping the economy into a major downturn.
'Goldilocks scenario'
Central banks spent last year ramping up borrowing costs to battle soaring prices and any sign of strength in the economy was taken as a bad sign that policymakers would continue to tighten policy sharply, threatening companies' profits.
The European Central Bank is also holding a monetary policy meeting next week, with analysts expecting a 50-basis-point rate increase.
Concern towards the end of the year focused on a possible global recession caused by the restrictive policies, with several observers warning that top economies were likely to suffer a so-called hard landing.
Thursday's US growth figures showed a slowdown in 2022 from the previous year but a better-than-expected performance.That was described as a "Goldilocks scenario", where the figures are neither too good nor too bad.
Yet lingering jitters persist of a possible downturn.
"There being a time lag between interest rate hikes and the effect on the economy, it remains difficult to predict how much of the Federal Reserve's actions so far are having the desired dampening effect," noted Interactive Investor analyst Richard Hunter.
"More pessimistic investors are suggesting that the latest quarter of growth could be the last before previous hikes take full effect, potentially pushing the economy towards recession this Spring."
Investors are also keeping a nervous eye on earnings season, which has thrown up some disappointing figures and downbeat forecasts, including from chip titan Intel.
Asian markets finished higher ahead of the latest US inflation data.Shanghai was closed for the Lunar New Year break and reopens next week.
