Dollar strengthens amid tensions and monetary policy shifts

According to Investing.com News, the US dollar strengthens driven by two key dynamics: tensions between the US and Iran, and rising expectations for a more hawkish Federal Reserve stance.

Volatility factors for traders

Geopolitical risks and commodities: Tensions between major powers directly affect oil and currency pairs like EURUSD, plus commodity-linked assets. Traders operate in uncertainty over sudden developments.

Interest rate expectations: If markets anticipate a tighter Fed, the dollar typically appreciates. This impacts currency pairs, equities, and bonds, creating shifting correlations.
