The US dollar began the week on solid footing, buoyed by a fragile diplomatic breakthrough between the United States and Iran that tempered immediate oil supply fears, even as broader currency risks persisted. The greenback held steady after high-level talks in Switzerland produced a 60-day roadmap toward a comprehensive agreement, backed by mediators Qatar and Pakistan. The plan includes further technical discussions and a channel aimed at protecting commercial shipping through the Strait of Hormuz.
Oil Risk Shifts to Currency Markets
Crude oil prices initially spiked after Iran indicated it had closed the waterway, but later eased as both sides signaled progress. Brent crude traded below $80 per barrel, suggesting energy traders have trimmed the immediate supply premium. However, currency investors remain cautious, as the path to a final deal is still uncertain. Shipping flows through Hormuz have already slowed, and any renewed threat to cargo movement could quickly feed back into oil, inflation expectations, and rate markets. Currency strategists note that FX and gold flows are likely to remain tied to the energy complex until traders see proof that vessels can move freely.
The dollar stayed supported against most major peers. The euro slipped to around $1.146, while the Australian dollar eased toward $0.700. The New Zealand dollar also remained under pressure, reflecting a broader preference for US assets at the start of the week.

Fed Repricing Keeps Yen Under Strain
The yen again looked like the weakest link, trading near 161.5 per dollar, close to levels that have previously drawn warnings from Tokyo. A move beyond 161.96 would put the currency near its weakest level since 1986. Japan's finance ministry repeated that it was ready to respond to excessive currency moves, but the market is testing that resolve. Analysts said intervention would be difficult while US yields are rising and the Federal Reserve is sounding more hawkish. Two-year Treasury yields climbed to their highest level since early 2025, with traders pricing a full quarter-point Fed rate increase by September and around 43 basis points of tightening this year. That rate gap leaves the yen exposed, even if the threat of official action slows the move.

UK Politics Drags on Sterling
Sterling carried its own domestic burden, falling around 0.2% to $1.3205 as traders watched Prime Minister Keir Starmer's position after Andy Burnham's decisive path into parliament revived questions over Labour's leadership. The market concern is not only political drama but also whether any leadership shift would bring looser fiscal rules, higher borrowing, and more pressure on gilts. Strategists said such a turn would probably weigh on the pound.
For now, the dollar's strength rests on three supports: Middle East uncertainty, rising US yields, and doubts elsewhere. None looks ready to disappear quickly. As oil markets remain sensitive to geopolitical developments, investors are also watching the interplay between energy prices and the dollar.
