FTSE 100 edges down as falling oil weigh on energy majors amid hot U.S. CPI

The benchmark FTSE 100 index experienced a slight decline on Tuesday, falling by approximately 0.3%, as falling global crude oil prices and a hotter-than-anticipated U.S. inflation report impacted the energy sector and weighed on the index. The FTSE 100's heavy emphasis on commodity stocks made it struggle to keep up with other European indices amid the prevailing bullish sentiment across European markets.

The primary driver of the London index's decline was the energy complex, with shares of oil giants Shell and BP falling to the bottom of the FTSE 100. These declines mirrored a broader liquidation in global energy markets. Brent crude futures experienced a further 0.8% drop, settling at $91.85 a barrel, a level not seen since early September and well below the psychologically significant $100 mark.

The energy sell-off intensified as investors grew increasingly confident of diplomatic talks between the United States and Iran, which eased the immediate threat of conflict and disrupted supplies in the Persian Gulf. This shift in the geopolitical outlook reduced the risk premium associated with UK energy producers, leading to a temporary reallocation of capital away from London's traditional dividend-paying stocks into broader consumer and industrial sectors.

The decline in oil prices provided some relief, but the overall risk appetite in the City faced significant challenges mid-session due to the release of the U.S. Consumer Price Index (CPI). The headline inflation rate rose by 0.4% in October, surpassing the 0.3% forecast, while the core CPI, which excludes food and energy components, also exceeded expectations, increasing to 0.3%.

This robust inflation data, released following a surprise increase in the U.S. jobs report the previous Friday, prompted a rapid revaluation of fixed-income markets and the Federal Reserve's potential interest-rate hike at the December meeting. Market participants now anticipate an 84% probability of a Fed rate hike at the upcoming December meeting, a substantial rise from the 74% probability just a week prior, as indicated by the CME FedWatch tool.
