Market Watch: Fed Policy and Ukraine Deal Drive Volatility in STOXX 600 and FTSE 100

 

​European equity markets, as measured by the pan-European STOXX 600 and the UK's FTSE 100, experienced a session characterized by sensitivity to global monetary policy signals and geopolitical developments on December 5, 2025. While overall sentiment trended towards caution, optimism over a widely anticipated US interest rate cut provided a foundation for gains, particularly in cyclically sensitive stocks.

​The market's attention was sharply divided between the upcoming US Federal Reserve (Fed) policy meeting and evolving news regarding a potential breakthrough in peace talks between Russia and Ukraine.

​The Federal Reserve's Shadow

​The primary driver for global risk appetite remained the anticipation of a forthcoming monetary easing cycle by the US Federal Reserve. Investors are closely monitoring economic data and central bank rhetoric for confirmation that the Fed is committed to cutting interest rates—a move that typically weakens the US Dollar and increases liquidity globally, benefiting non-US assets like European equities.

​On December 5, the prevailing mood was one of certainty regarding an imminent rate cut. This expectation provided a tailwind for the STOXX 600, allowing the index to post modest gains.

​Impact on Sectors: The belief in lower rates boosted sectors that perform well in a growth environment. Technology stocks, which rely on accessible capital for expansion, showed particular strength across Europe. Industrial stocks also benefited from this 'risk-on' sentiment, suggesting increased confidence in future business spending.

​The FTSE 100 in London, however, frequently lagged behind its European counterparts. Due to its heavy weighting in "old economy" sectors like banks, energy, and tobacco, the UK benchmark often struggles when global risk appetite favors growth and technology stocks. Bank stocks, in particular, may have weighed on the FTSE 100 as the prospect of lower interest rates often narrows lending margins.

​Geopolitical Catalyst: Ukraine Peace Speculation

​The second major focal point was the ongoing situation between Russia and Ukraine. In late 2025, any significant movement toward a peace agreement or cease-fire triggers major reactions across the European stock market, with conflicting effects on key sectors:

​Positive Impact (Commodity & Infrastructure): Any credible progress toward a deal tends to buoy commodity stocks (oil and gas, metals) on the expectation of stabilized supply chains and lower energy price volatility. Furthermore, construction and building materials companies often see gains as markets price in massive future reconstruction efforts in Ukraine.

​Negative Impact (Defense): Conversely, reports of an imminent peace deal typically cause a sharp drop in aerospace and defense stocks. Companies like Rheinmetall or Leonardo, which have seen massive gains due to high defense spending, can face losses as the geopolitical risk premium is removed from their valuations.

​On this particular day, while overall sentiment was cautiously positive due to the Fed outlook, the lack of a firm, confirmed deal meant that geopolitical risk remained elevated, providing a fluctuating influence on defense and commodity names.

​In sum, the market on December 5 was defined by a classic tug-of-war: the fundamental hope for cheaper capital from the Fed fighting against the persistent uncertainty of the war in Ukraine, leading to a session where sector performance was highly differentiated.
