Cautious Optimism on Wall Street: Trump Hints at Iran Deal, but the Dollar Refuses to Blink
A Much More Skeptical Market: For the second time this May, global markets are trying to digest a potential U.S.-Iran peace deal after President Trump claimed negotiations are in their “final stages.” However, market conviction is significantly lower this time. Having been burned by false dawns earlier this month, the intraday drop in the Dollar Index (DXY) was only half the size of the move seen on May 6.

Global Market News: Key Developments Across Major Assets on May 21, 2026
- The technology sector experienced positive momentum driven by strong earnings from Nvidia, which reported sales exceeding market expectations. Sentiment was further supported by an averted labor strike at Samsung Electronics, avoiding global semiconductor supply disruptions. In corporate news, Eightco Holdings announced its treasury reached $337 million, including indirect investments in OpenAI.
- Germany’s DAX 40 index fell 0.6 percent to trade below 24,600. The market faced pressure from data indicating Germany’s private sector contracted for a second consecutive month in May. The European Commission also lowered Eurozone GDP forecasts while raising inflation expectations. Commerzbank shares dropped 4 percent after rejecting a 39 billion euro takeover offer from UniCredit, though Infineon advanced following Nvidia’s earnings.
- Japan’s Nikkei 225 index surged over 3.5 percent to cross 61,900, marking its largest daily advance in two weeks. The index tracked Wall Street’s technology rally and reacted to domestic data showing Japanese exports rose 14.8 percent in April. Technology and financial shares led the gains, with SoftBank Group and Tokyo Electron surging amid optimism regarding a potential US-Iran peace deal that could ease national energy costs.
- Brent crude oil futures rebounded to trade near $105.80 per barrel. This slight increase followed a steep 5.6 percent drop on Wednesday after reports that US-Iran peace negotiations were in their final stages. Today’s price recovery was driven by lingering uncertainty over the final diplomatic agreement, alongside a notable draw in United States petroleum inventories that heightened concerns over tightening global energy supplies.
