The European session saw mixed performance, with the DAX and FTSE closing slightly down as investors digested varying PMI data and corporate earnings. Siemens Healthineers' reduced forecast contributed to a cautious mood in Germany, while the UK faced broader selling pressure. However, the dominant theme for the global pre-market has been significant optimism stemming from hints of a potential US-Iran peace deal. This prospect ignited a strong rally across Asian markets, with major indices like the Nikkei and Hang Seng posting impressive gains, especially in big tech. This 'risk-on' sentiment has translated into a weaker US Dollar, as safe-haven demand diminishes, while boosting some commodities like gold and silver. Conversely, crude oil prices are sharply lower on reduced geopolitical supply risk. US equity futures are showing a slight pause, taking a breath after the Asian surge, as investors prepare for domestic data and key speeches from Fed Chair Powell, ECB President Lagarde, and BOE Governor Bailey which could shape the US trading day.

The primary risk for the US session revolves around Fed Chair Powell's remarks. Any hawkish surprises or concerns about persistent inflation could quickly reverse the current optimistic sentiment. Initial Jobless Claims and Existing Home Sales data will provide insights into the US labor market and housing sector. Furthermore, speeches from other central bank leaders (Lagarde, Bailey, Ueda) will be scrutinized for global monetary policy signals. Any unexpected negative corporate news or escalation of other geopolitical tensions (despite Iran optimism) could also trigger a market correction. The sustainability of the 'Iran deal' optimism will be key.
