The Paris Bourse ended Wednesday (+ 0.61%), after a very nervous day, breaking with four sessions of recoil under the fears generated by the new outbreak of Sino-US commercial fever.

The CAC 40 index gained 31.86 points to finish at 5.266.51 points, in a volume of exchanges increased by 3.7 billion euros. The day before, it had ended in slight ebb (-0.13%).

The Parisian rating had a dynamic start to session before seriously doubting the point of passing briefly in the red, weakened by the misdirection of Wall Street, but then regained ground at the end of the session.

"The market has benefited from the easing of trade tensions in the morning, even exceeding the threshold of 5,300 points," said AFP Lara Nguyen, an expert in financial investments at Milleis Bank.

But it was then weakened by a series of factors, new tweets from the US president demanding more from the Fed until the fall of Wall Street, through the decline in bond market borrowings, did it? -she adds.

US President Donald Trump reiterated on Wednesday, in a long series of tweets, his diatribes against the US Central Bank (Fed), demanding that it reduce rates "faster and stronger" and calling it "incompetent".

This new offensive has added to fears for global trade and the risks it poses to growth, pulling US borrowing rates down, and Wall Street in their wake.

"In the end the market remains very nervous" because investors "lack tangible elements," summarized Ms. Nguyen. "They had returned to the fundamentals", notably thanks to the results of companies at the end of July, but "they are now again confronted with the political hazards, more difficult to anticipate".

"It may also encourage a certain wait-and-see attitude in markets, which will try to hold on year after year until the big Jackson Hole central bankers meeting" in the United States at the end of August, according to the expert.

Donald Trump had set fire to the dust Thursday night by waving the threat of new trade sanctions against China, creating stupefaction in the markets. In retaliation, Beijing had asked its public companies to stop buying US agricultural products.

The tension then turned to the monetary field, China allowing its currency to weaken. Washington then accused it of manipulating its currency to support its exports.

In an attempt to defuse the situation, the Chinese Central Bank intervened to stabilize the yuan, which had crossed Monday the symbolic threshold of 7 yuan to the dollar, its lowest level in 11 years.
