European equity markets were set to open on a downward trajectory on Tuesday, weighed down by increasing tensions between Israel and Iran. Investor confidence waned as U.S. President Donald Trump urged for a complete evacuation of Tehran amidst ongoing Israeli airstrikes, emphasizing that Iran should have accepted his nuclear deal proposition. Further intensifying the geopolitical strain, the G7 issued a statement in support of Israel, identifying Iran as the "principal source of regional instability and terror." Domestically, investors are anticipating the release of the Eurozone and Germany’s ZEW economic sentiment surveys for June, which could provide insights into the region's growth prospects. No major corporate earnings announcements are expected today. During pre-market trading, futures for both the Euro Stoxx 50 and Stoxx 600 were down roughly 0.7%.
