US-Iran diplomacy impact on USD

What happened: The US dollar experienced a volatile week, driven primarily by developments in US-Iran diplomacy. On June 12, the dollar steadied but was on track for a weekly loss, as markets monitored US-Iran deal talks. Positive signals from President Trump and Iran's foreign minister boosted hopes for a peace deal, driving the dollar index (DXY00) to a 2.5-month low on June 15 (-0.45%). However, the dollar recovered on June 16 (+0.03%) due to conflicting signals about a US-Iran deal.

Market impact: The US dollar's performance affected global markets, with safe-haven demand ebbing and flowing based on diplomatic progress. The dollar's decline led to a rebound in stock markets and a drop in crude oil prices, as tensions eased. Meanwhile, the Japanese yen appreciated on safe-haven demand, sparking intervention chatter.

What to watch next: Investors should monitor the progress of US-Iran peace talks, with key catalysts including any official announcements on a deal (or lack thereof) and the release of US non-farm payroll data on June 19. Additionally, traders should keep an eye on the 10-year Treasury yield, which supports the dollar through interest rate differentials.
