(BFM Stock Exchange) – The Parisian index closes slightly, on the eve of the entry into force of new American customs duties.

The Paris Stock Exchange has advanced with felt steps. After losing 0.14% the day before, the CAC 40, its reference index, slight closure increased from 0.18% to 7,636.03 points, this Wednesday, August 6.

The market was very attentive to new announcements on American customs surcharge, while new customs duties, as acted in the decrees signed last week by Donald Trump, will enter into force on August 7, that is to say on Thursday. As a reminder, the rate applied to European products will increase to 15%, as for Japan or South Korea.

“The markets first welcomed the revised customs agreements, in particular with Japan and the European Union, but this optimism fades quickly,” observes Stephen Innes of Spi am.

Some countries are still trying to win a last minute agreement. The main Japanese commercial negotiator is currently in Washington to clarify the details of what was supposed to be a concluded agreement, while the Swiss Minister of Finance tries to lower the high rate by 39%.

India, it saw its customs treatment substantially grow this Wednesday, Donald Trump accusing the country for buying Russian oil. By decree, India is imposed an additional 25% surcharge on Indian products, which is added to that of 25% which is to enter this Thursday.

GTT penalized by Berenberg

On the side of the values, Totalenergies won 1.2%, approaching the increase in its comparable BP which takes 2.3% in London after revealing quarterly results marked by an operating profit and an operational cash flow greater than expectations, according to UBS.

Excluding CAC 40, GTT made 1.8%, suffering from a degradation of Berenberg who went from “to buy” to “keep” on the title.

In Frankfurt, Beiersdorf, owner of Nivea, fell 8.6% after lowering its prospects for 2025.

In other markets, the euro takes 0.5% against the dollar at 1.1636 dollars. Oil rises. The October Brent of the North Brent contract takes 0.8% at 68.20 dollars per barrel while that of September on the WTI listed in New York advances from 0.9% to 65.74 dollars per barrel.
