European stock markets were set to open lower on Wednesday, with investors remaining cautious ahead of US President Donald Trump’s anticipated announcement regarding new tariffs. There are indications that Trump is contemplating a flat 20% tariff on a wide range of imports, although a strategy targeting specific countries with reciprocal measures is still expected to prevail. Additionally, Europe has no significant economic or earnings reports scheduled for release today. In premarket trading, futures for both the Euro Stoxx 50 and Stoxx 600 were down approximately 0.2%.
