Brent below $90, CAC 40 at its highest in two months

The fall in oil prices supported the Paris stock market on 10 November. Stronger-than-expected US inflation, however, weighed on the open on Wall Street.

The facts

According to Investir Les Echos, the CAC 40 was up about 1% in the middle of the day on 10 November. A barrel of Brent was then trading below $90, a first since August. The outlet put US inflation in focus.

At the close, Investir Les Echos says the Paris index reached its highest level in two months. The article’s headline attributes this move to the continued fall in oil prices.

BFM Bourse describes a drop in oil prices that gives the CAC 40 a boost. According to the site, Wall Street opens in the red because of stronger-than-expected US inflation.

The following morning, Boursorama says Europe is expected to open higher. The outlet mentions strengthened bets on Fed rates. The available information does not specify the exact level of inflation or the precise direction of these bets.

Our take

Take: the link between oil and the Paris stock market is simple to understand. A cheaper barrel lowers costs for many sectors and reduces pressure on prices. The cited outlets clearly associate it with the rise in the CAC 40. However, the sources do not detail which stocks drove the index, or whether other factors played a role.

The contrast with Wall Street deserves a mention. Falling oil helps Europe, while higher-than-expected US inflation feeds concerns about Fed policy. Markets are therefore moving forward with two signals that do not point in the same direction. Hesitation across the Atlantic could spill over into European markets if it persists.

These observations are based on article headlines and summaries, not on their full text. Caution is therefore needed on the real size of the moves and on their durability.

Risks to watch

The oil price could rebound as quickly as it fell, which would remove one of the supports for the CAC 40. Persistent US inflation could harden expectations on Fed rates and weigh on equity markets. Finally, a rise driven by a single factor remains fragile if that factor reverses.
