The US dollar stabilized Thursday after strong quarterly results from AI leader Nvidia (NVDA) boosted investor confidence, offsetting earlier losses. Nvidia's sales exceeded analyst forecasts and projected current-quarter revenue above expectations, providing a positive catalyst for markets. However, traders remain cautious, awaiting clarity on the Trump administration's response to the Supreme Court's recent ruling against emergency tariffs.

The US Trade Representative indicated some countries' rates could rise to 15% or higher from the current 10%, though specific targets weren't named. Simultaneously, US and Iranian officials are meeting in Geneva to discuss a potential nuclear deal, with President Trump threatening consequences if progress stalls. Analysts suggest the Nvidia-driven dollar relief might be temporary, with the Iran situation posing the biggest near-term risk for a broader dollar rally.
