Paris (France) (AFP) – The Paris Stock Exchange ended Monday in a slight decline before the main courses of the week, namely the meeting of the European Central Bank (ECB) and the announcement of quarterly tech results, without forgetting the tensions around the Strait of Hormuz.

The flagship CAC 40 index fell 0.19%, a loss of 15.90 points to 8,141.92 points. However, the “CAC” had started the day slightly up before skepticism took over.

In addition to waiting for the major meetings of the week, the markets must integrate "the apparent paralysis of negotiations and military actions in the Middle East", according to analyst Andreas Lipkow of CMC Markets.

Nothing new in fact on the Middle East front and the closure of the Strait of Hormuz, which maintains tension on global supply and therefore oil prices.

Iran is "stable, robust", declared its head of diplomacy Abbas Araghchi on a visit to Russia, where he blamed the United States for the failure of the negotiations.

US President Donald Trump is due to hold a crisis meeting on Iran on Monday, according to US media.

Under these conditions, Brent oil from the North Sea, the benchmark for crude in Europe, increased by almost 3% (+2.91%) to 108.40 dollars per barrel shortly before 7:00 p.m.

Its American equivalent of WTI increased by 1.90% to $96.19.

“Before the conflict, around 15 million barrels per day passed through the Strait of Hormuz, indicating that around 6 million barrels per day are in short supply, without taking into account other petroleum products,” argue Ben Jones and Ashley Oerth for the asset management company Invesco.

In this context of inflation risks, the markets will listen carefully to the comments of the President of the Central Bank (ECB) Christine Lagarde on Thursday.

“The European Central Bank (ECB) should opt for the status quo, maintaining its key rates at 2%,” comments Kevin Thouzet for Carmignac.

“We still anticipate two rate increases from June. Only a significant drop in oil prices, below $80 per barrel, would be likely to justify a prolonged pause,” he adds.

On the bond market (interest rate requested by borrowers who finance State debt), the yield on French debt over ten years rose to 3.68% compared to 3.63% on Friday.

When there is a risk of inflation, creditors demand higher interest rates.

Outside the CAC 40, the action of Ose Immuno (pharmaceutical industry) jumped 20.97% to 3.66 euros per share, due to an authorization of drug designation for the prevention of heart transplant rejection in the United States by the Food and Drug Administration (FDA).
