The US dollar posted its sharpest single-session decline in more than a month after President Donald Trump signaled that talks with Iran were making meaningful progress. The announcement flipped a switch in global markets, pulling capital away from safe-haven assets and into riskier corners of the financial universe, including crypto.

The dollar index dropped to approximately 98.9, marking a notable retreat that caught the attention of forex traders and crypto investors alike.

What happened and why it matters

Trump’s comments around late May pointed to tangible progress in negotiations with Iran, a development that immediately dampened demand for the dollar. Geopolitical tension typically drives investors toward safe havens like the greenback and US Treasuries. Remove that tension, even partially, and the trade unwinds.

Oil prices also softened on the prospect that the Strait of Hormuz, one of the world’s most critical chokepoints for energy supply, could see reduced risk. Risk-on sentiment surged across asset classes. Bitcoin and Ether both posted gains exceeding 3% during certain trading sessions as the broader crypto market cap rebounded by an estimated $75 billion following the positive Iran-related news.
