FTSE 100 Declines Amidst Mixed US Inflation Data and Mining Sector Weakness
The FTSE 100 index experienced a downturn, closing the day lower as investors reacted to US inflation figures and specific company news. Mining stocks, particularly Antofagasta, led the decline following production guidance cuts.
Key takeaways
- The FTSE 100 index closed down 54 points at 10,778.
- US inflation data and jobless claims influenced market sentiment, prompting adjustments to Federal Reserve rate hike expectations.
- Antofagasta's reduced copper production guidance, due to severe weather in Chile, significantly impacted the mining sector and the FTSE 100.
- Analyst ratings for UK insurance companies Aviva, Legal & General, and M&G were adjusted by JP Morgan.
The FTSE 100 index finished the trading day in negative territory, registering a decline of 54 points to close at 10,778. The performance lagged behind a more positive mood in the United States, where the Dow Jones Industrial Average and S&P 500 saw modest gains.
What Happened
US markets reacted to producer price index data that came in below expectations, with core readings showing a slowdown both monthly and annually. This followed a cooler consumer price figure from the previous day, leading traders to reduce bets on a September interest rate hike by the Federal Reserve. However, US jobless claims presented a mixed picture, with initial filings increasing while continuing claims fell.
In London, the mining sector was a significant drag on the FTSE 100. Copper producer Antofagasta was the index's largest faller, shedding 5% after it revised its 2026 copper production guidance downward. The company cited severe storms in Chile, which led to a shutdown at its Los Pelambres mine and a government-declared state of catastrophe in the Coquimbo region, as the cause for the reduced forecast.
The insurance sector also saw notable shifts. JP Morgan upgraded Aviva to 'overweight' while downgrading Legal & General Group and M&G to 'underweight,' suggesting a change in relative value within the UK life insurance sector. Standard Life maintained its 'overweight' rating.
