US equity futures tumbled during European trading hours Tuesday as surging Treasury yields and escalating tensions between Washington and Tehran spooked investors. Dow Jones futures dropped 0.25% to approximately 53,410, while S&P 500 futures fell harder at 0.52% near 7,730. Tech-heavy Nasdaq 100 futures led losses with a 0.92% decline to around 29,820, reflecting sector-specific pressure from rising borrowing costs.

The selloff comes as Treasury yields continue their upward climb, raising concerns about valuations in rate-sensitive growth stocks and increasing debt servicing costs for corporations. Simultaneously, heightened US-Iran geopolitical friction adds uncertainty to global risk appetite, threatening energy supply stability and broader market sentiment. Technology shares face particular vulnerability given their sensitivity to interest rate movements and lofty valuations established during the low-rate environment.

FXnCO Insight

Traders should monitor the 30,000 level on Nasdaq futures as a critical technical support while positioning defensively in sectors less exposed to rate volatility.
