European stock markets are anticipated to open broadly higher on Wednesday, with ongoing volatility stemming from the Iran conflict remaining a key focus ahead of the Federal Reserve's upcoming policy announcement. According to IG data, the UK's FTSE 100 index is projected to open flat, underperforming other European markets. Germany's DAX index and France's CAC 40 index are expected to open approximately 0.5% higher, while Italy's FTSE MIB index is forecast to rise around 0.8%. Despite oil prices climbing above $100 per barrel due to renewed supply concerns fueled by continued U.S.-Iran tensions, global equities advanced overall on Tuesday. U.S. President Donald Trump criticized NATO allies this week for declining to assist in protecting vessels transiting the Strait of Hormuz, but stated in a Tuesday post on Truth Social that America did not require external help. Oil markets remain in focus: although attacks on energy facilities in the UAE have increased, prices retreated overnight as rising U.S. crude inventories offset geopolitical risk premiums. Investors are now awaiting the Federal Reserve's interest rate decision, scheduled for release later on Wednesday. Markets expect the Fed to maintain rates within the 3.5% to 3.75% range. Traders will closely monitor any guidance from Fed Chair Jerome Powell regarding whether oil prices could influence future monetary policy decisions. In Europe, investors are awaiting Eurozone inflation data due later in the day. This data will be released ahead of monetary policy announcements from the European Central Bank, the Bank of England, the Swedish Riksbank, and the Swiss National Bank on Thursday.
