Nasdaq Drops as Nvidia Disappoints and Iran Tensions Hit Risk Sentiment

US equity markets faced significant selling pressure on Wednesday, with the Nasdaq 100 declining sharply after Nvidia's results failed to meet elevated market expectations, triggering a broader risk-off move across global markets. Compounding the negative sentiment, renewed geopolitical concerns surrounding Iran added a layer of uncertainty, pushing investors toward safe-haven assets. The combination of tech sector weakness and Middle Eastern tensions is weighing on risk-correlated currencies such as AUD/USD and NZD/USD, while supporting traditional havens including the Japanese yen, Swiss franc, and gold. USD/JPY faces downward pressure as yen demand increases amid the flight to safety. The dollar index is seeing mixed flows, benefiting from haven demand but constrained by falling US Treasury yields as equity weakness raises questions about the economic outlook. Traders should monitor upcoming geopolitical developments regarding Iran and broader tech sector sentiment, as sustained risk aversion could drive further safe-haven flows and increase volatility across major forex pairs in the near term.
