CAC 40 Rebounds 0.92% as Oil Slips and Chip Stocks Rally
Paris stocks recovered 73.92 points on Monday, driven by falling crude oil prices and a surge in semiconductor equities ahead of the Trump-Xi summit.
Key points
- CAC 40 closed at 8,138.94, up 0.92% from Friday, recovering most of the previous day's losses.
- Brent crude fell below $100 for the fourth straight day, easing pressure on European corporate input costs.
- Chip stocks like Soitec and STMicroelectronics led a tech rally, supported by successful US-China diplomatic talks.
The CAC 40 index closed at 8,138.94 on Monday, 21 September 2026, marking a gain of 73.92 points or 0.92% from the previous session. This recovery clawed back roughly three-fifths of the losses sustained during Friday's sharp sell-off, signaling a return to risk appetite after a volatile week for European markets.
The rally was primarily fueled by a fourth consecutive drop in Brent crude prices, which fell below $100 per barrel, and a strong performance in the technology sector. According to reports from the BBN Times, these factors combined with easing US Treasury yields to support broader equity valuations ahead of the scheduled Trump-Xi summit.
Energy Costs Ease Corporate Margins
Brent crude’s decline below the $100 threshold acted as a direct relief valve for European corporate margins. Since Europe imports the majority of its fuel, lower energy prices reduce input costs for industries such as industrials and transportation. This dynamic also helps anchor inflation expectations, providing a more favorable backdrop for companies operating under the European Central Bank’s recent interest rate hikes.
Semiconductor Shares Lead Sector Gains
The pan-European STOXX 600 technology sector advanced approximately 2% during morning trade, driven by strength in chip-linked equities. Soitec and Aixtron tracked gains among their US peers, while STMicroelectronics rose more than 3% in Milan despite trading ex-dividend. This sector-specific rally contributed significantly to the index’s overall positive performance, offsetting weakness in other areas.
Diplomatic Prospects Support Risk Appetite
Investor sentiment was further bolstered by diplomatic developments between the United States and China. US Treasury Secretary Scott Bessent described weekend talks with Chinese Vice Premier He Lifeng as very successful, while the upcoming meeting between Presidents Trump and Xi on 24 September encouraged traders to lean towards risk rather than defensive positions. This geopolitical clarity reduced uncertainty for multinational firms exposed to cross-border trade.
