The U.S. dollar index entered Wednesday trading under pressure as longer-dated Treasury yields retreated and oil prices declined, setting the stage for the Federal Reserve’s preferred inflation gauge to determine whether the recent bond market rally can extend.
Longer-dated U.S. Treasury yields have eased over the past week following Treasury Secretary Scott Bessent’s decision to expand buybacks of long-dated government debt. The 10-year yield fell to around 4.63% on Tuesday, while the 30-year yield approached 5.16%, reflecting reduced term premiums and easing inflation concerns tied to energy prices. Crude oil futures have fallen for three consecutive sessions, with Brent crude approaching $86 per barrel as markets price in potential easing of tensions in the Strait of Hormuz. Lower energy costs ease one of the more immediate inflation pressures, reinforcing the case for contained longer-term yields.
The focus now shifts to the July core Personal Consumption Expenditures (PCE) report, due later on Wednesday. Economists expect the year-over-year core PCE reading to remain around 3.3%, still above the Fed’s 2% target but below prior peaks. The monthly figure is the more consequential metric, with a reading of 0.2% or softer aligning with the narrative that inflation risks are easing. Such a result would support the view that energy price declines and contained yields reduce the urgency for additional Fed tightening, potentially keeping the dollar subdued.
Conversely, a core PCE reading of 0.3% would signal persistent underlying inflation pressures, while a 0.4% or higher outcome could prompt a reassessment of Fed rate hike expectations. In that scenario, Treasury yields could rebound, providing a potential catalyst for dollar strength. Boston Fed President Susan Collins underscored the sensitivity of policy to incoming data, noting that rates may need to rise further unless inflation data shows convincing progress toward the Fed’s objective.
Technical levels add further context. The U.S. dollar index has broken below the lower boundary of a multi-month rising channel, a development that shifts the bias toward a deeper correction. The index is currently trading near 99.00, and unless it quickly reclaims the broken channel, the next significant support zone is seen between 97.65 and 98.00. This area has previously attracted buying interest and represents the key downside risk if today’s PCE data sustains the bond market rally.
The dollar’s path remains contingent on multiple catalysts this week. Following the PCE release, markets will assess a $44 billion seven-year Treasury auction on Thursday, followed by remarks from Federal Reserve Chair Kevin Warsh at the Jackson Hole symposium on Friday. These events create a concentrated sequence of catalysts for rates and currency markets.
For now, the dollar remains on the defensive. Oil prices are falling, longer-dated yields have pulled back from recent highs, and the dollar index has breached its technical uptrend. If the PCE data fails to challenge this combination, the 97.65–98.00 support zone may emerge as the next key level for the dollar index.
