Key Points
US Dollar Index fell to 99.4, a 3-month low, as Fed rate hike odds dropped to 35%.
ECB expected to raise rates by 25 basis points in September, supporting euro strength.
Higher Treasury yields may reflect fiscal risk rather than economic growth, weakening dollar support.
Policy divergence between dovish Fed and hawkish ECB continues to pressure the greenback.
The US dollar has slumped to a three-month low against the euro, with the Dollar Index trading at 99.4 as of August 20. Softer US employment, inflation, and consumption data have cut Fed rate hike odds to just 35% for September, while the European Central Bank is poised to raise rates by 25 basis points next month. Currency strategists warn that higher Treasury yields may reflect fiscal risk rather than economic strength, undermining traditional dollar support.
Why the dollar is weakening against the euro
The US Dollar Index has fallen from its 52-week high of 101.80 on June 24 to 99.4, a slide driven by dimming rate hike expectations. Recent US data showed negative jobs reports, milder inflation, and weak retail spending. Meanwhile, 57 of 69 economists surveyed by Reuters expect the ECB to raise rates by 25 basis points in September, moving from 2% to 2.5%. This policy divergence favors the euro, which benefits from a more hawkish central bank even as eurozone inflation sits at 2.9% versus the ECB’s 2% target.
Treasury yields no longer guarantee dollar strength
Higher US bond yields have historically supported the dollar by attracting foreign capital. The 30-year Treasury yield recently hit its highest level since 2007. However, Charu Chanana, chief investment strategist at Saxo, warns that yields driven by fiscal risk and government borrowing may not support the dollar the way yields from stronger growth or tighter Fed policy do. If investors see rising yields as a warning sign rather than a strength signal, the dollar loses its traditional anchor.
Fed rate expectations have shifted sharply
Markets now price a 65% probability that the Federal Reserve will hold rates steady at its September meeting, with only 35% odds of a rate hike. This represents a major shift from earlier expectations. The upcoming release of July Fed meeting minutes will clarify how divided committee members were on the rate decision, potentially adding to dollar volatility. Uncertainty over Fed policy is a key headwind for the greenback.
What this means for Swiss franc and euro holders
For Swiss and European investors, a weaker dollar makes US assets less attractive on currency grounds alone. The euro has strengthened against the dollar, while the Swiss franc typically benefits from safe-haven demand during periods of policy uncertainty. Investors holding dollar-denominated assets face headwinds unless US economic data rebounds or the Fed signals more aggressive rate hikes ahead.
Final Thoughts
The dollar’s slide to a three-month low reflects a fundamental shift in rate expectations and investor confidence in US fiscal health. Until the Fed delivers clearer guidance or US economic data improves, the greenback faces continued pressure against the euro and other major currencies.
