US Dollar Faces Downside Risks as Policy Events Drive Market Sentiment

The US Dollar remained broadly stable at the start of the week, although investors are increasingly focused on policy developments that could shape the currency's near-term direction. MUFG strategist Derek Halpenny noted that concerns over potential US Dollar debasement have returned as markets assess how the US Treasury may respond to rising long-term bond yields. While MUFG does not expect a repeat of the sharp Dollar selloff seen earlier in the year, the bank believes several upcoming events could weaken sentiment toward the currency. One major focus is Treasury Secretary Scott Bessent's expected update on the administration's economic and fiscal plans. Investors are looking for credible measures that could help contain longer-term Treasury yields and improve confidence in the US fiscal outlook. ### Iran Developments Could Drive Dollar Volatility Markets are also watching potential US policy actions related to Iran. A stronger-than-expected response could push crude oil prices higher and initially support the US Dollar through increased demand for safe-haven assets. However, MUFG cautions that geopolitical developments alone may not determine the Dollar's direction because broader concerns about fiscal policy and currency debasement remain important drivers. ### Treasury Yields Remain in Focus Long-term US Treasury yields are another key risk for currency markets. Investors remain concerned that insufficient progress on fiscal consolidation could place additional pressure on longer-dated bonds. If oil prices rise at the same time as fiscal concerns intensify, MUFG believes the 30-year Treasury yield could challenge or move above the recent 5.34% high. Higher long-term yields would normally provide some support to the Dollar, but a rise driven by concerns over government borrowing and fiscal sustainability could instead damage confidence in US assets. ### Jackson Hole Speech Could Shape Fed Expectations Attention will also turn to Federal Reserve Chair Warsh's Jackson Hole speech. Markets will closely examine his comments for signals about inflation, interest rates, economic growth and the outlook for US monetary policy. MUFG expects the speech could maintain pressure on the longer end of the Treasury market, particularly if investors receive little reassurance regarding fiscal consolidation. ### US Dollar Outlook The balance of risks for the US Dollar appears tilted to the downside in the near term. Investors are monitoring several interconnected factors, including Treasury policy, fiscal consolidation plans, developments involving Iran, crude oil prices and signals from the Federal Reserve. Any disappointment around fiscal measures or a renewed rise in long-term Treasury yields could weaken Dollar sentiment. Conversely, stronger policy credibility or increased safe-haven demand could provide temporary support. For now, traders are likely to remain cautious as this week's major policy events unfold.
