The star CAC 40 index lost 72.72 points to 7,160.93 points around 9:55 a.m. (08:55 GMT).
On Friday, it had taken 0.94% and ended its fifth week in the green since the start of the year.
The Paris market continues to digest the announcements of last week.
Initially pleased by the tone of the US, EU and UK central banks, markets were held back by a strong US jobs report.
Job creations far exceeded analysts' forecasts and the unemployment rate hit a 50-year low, sending the New York Stock Exchange into the red on fears of further rate hikes.
"Following their strong rebound, according to central banks, in the middle of last week, markets are consolidating a bit following very strong US jobs reports on Friday, which cast doubt on the Fed's ability to stop its fight against the inflation rapidly", comments Xavier Chapard, from the research and strategy team at La Banque Postale AM.
These questions will continue this week with the speeches of several American central bankers scheduled for this week.
Jerome Powell, the chairman of the Fed will speak Tuesday in Washington, before a hearing before the European Parliament of Christine Lagarde, president of the ECB, on Wednesday.
Geopolitical concerns add to this gloomy context after the United States shot down the Chinese balloon which had been flying over their soil for several days.
The Chinese government said Monday that the United States has "seriously affected and damaged" relations between the two countries and the head of American diplomacy Antony Blinken postponed his visit to Beijing.
"This calls into question the dynamic of calming tensions between the two great powers which had begun with the interview between Xi and Biden in mid-November and is a reminder that the geopolitical environment remains very difficult", explains Xavier Chapard.
Renault and Nissan clarify their agreement
The two automakers confirmed on Monday the "rebalancing" of their cross-shareholdings.
While Renault held 43.4% of Nissan, the two companies will enter into a new agreement under which Nissan and Renault Group will hold a "cross-shareholding of 15%, with an obligation to hold, as well as an obligation to cap their participations. ".
Renault shares were stable (+0.10%) at 39.05 euros, while Nissan rose 2.12% in Tokyo, ahead of the announcements.
