US Futures Slide After Iran's Pars Field Attack; FOMC Decision Ahead

US equity futures have slumped sharply, erasing overnight gains following reports of an attack on Iran's giant South Pars gas field, sending shockwaves through global markets and amplifying risk-off flows in the forex space. The attack has intensified fears of a broader Middle East conflict and further disruptions to global energy supply, pushing crude oil prices higher and driving demand for safe-haven currencies including the US dollar, Japanese yen, and Swiss franc. EUR/USD is facing downward pressure as traders de-risk ahead of this week's dual central bank events — the FOMC and ECB policy decisions. The US Dollar Index futures are trading higher on safe-haven demand, though gains may be capped if the Federal Reserve signals a dovish tilt. Immediate attention is on the FOMC statement and dot plot projections, which will set the tone for USD direction in coming weeks. Traders are advised to manage position sizes carefully given the elevated geopolitical uncertainty and the potential for sharp intraday reversals around the Fed announcement.
