Global markets experienced a downturn as investors focused on corporate earnings reports and escalating tensions between the United States and Iran. European stocks, tracked by the STOXX 600 index, fell 0.6%, with significant drops seen in shares of Airbus and Rio Tinto following underwhelming financial results. This comes after a record high the previous day, boosted by defense and banking sectors.

Futures for the U.S. S&P 500 and Nasdaq also declined, indicating continued market volatility. Investors are closely watching earnings, including Walmart's forecast which fell below expectations. This follows a strong performance on Wall Street driven by Nvidia's AI chip deal with Meta Platforms, though these tech giants saw pre-market declines.

Geopolitical factors are contributing to market uncertainty. Rising U.S.-Iran tensions are impacting oil prices, which extended gains due to concerns over potential supply disruptions. Brent crude futures traded around $71.41 a barrel, near late January highs. Gold, a traditional safe-haven asset, saw a modest rise.

The U.S. dollar maintained its gains following positive economic data and Federal Reserve meeting minutes. The minutes suggested a potential openness to rate hikes if inflation persists, signaling a resilient U.S. economy which could support global growth. Asian markets showed a slight increase, though trading was impacted by Lunar New Year holidays.
