European equity markets were headed for a higher open on Wednesday as investors prepared for the latest US Federal Reserve policy decision, where it is widely expected to deliver a 25 basis point rate cut. In Europe, investors will assess UK inflation figures for August, as well as final inflation data for the Eurozone. Later this week, the Bank of England will likely keep policy unchanged as consumer prices have continued to tick higher in recent months. Meanwhile, no major corporate earnings are scheduled in the region. In premarket trade, Euro Stoxx 50 and Stoxx 600 futures were up 0.3% and 0.2%, respectively.
