Market Overview

London’s blue‑chip FTSE 100 advanced 0.8% on Tuesday, buoyed by a sharp decline in global crude oil prices. Benchmark Brent futures slipped another 1% during the session, settling at $91.56 a barrel – the lowest level since early September and comfortably below the psychological $100 barrier.

Impact on Energy Sector

Despite the broader market lift, heavyweight UK energy producers recorded steep losses, dragging on the rally. The energy sell‑off intensified as investors priced in the possibility of renewed diplomatic talks between the United States and Iran, which reduces the perceived risk of supply disruptions in the Persian Gulf and consequently lowers the risk premium attached to UK energy stocks.

Macro‑Economic Context

Traders were also cautious ahead of the release of the October U.S. Consumer Price Index (CPI) later in the session. Economists expect the CPI to show a moderate increase in prices, yet remain high enough to justify further restrictive action by the Federal Reserve. The market’s attention to the CPI is heightened after a blow‑out U.S. jobs report last Friday, which prompted fixed‑income markets to aggressively reprice the Fed’s year‑end trajectory.

Fed Rate‑Hike Expectations

According to the CME FedWatch tool, the probability of a Federal Reserve interest‑rate hike at the December meeting rose to 84%, up from 74% a week earlier. A hotter‑than‑expected inflation print would likely cement these hawkish expectations, potentially tightening global financial conditions and increasing cross‑border volatility.

Overall Sentiment

The FTSE’s gain reflects underlying bullishness across European bourses, but the index’s heavy weighting in commodity stocks limited the upside, as energy‑related losses offset broader consumer and industrial gains.
