The US Dollar Index staged a modest recovery on Monday, August 24, 2026, but remains close to multi-month lows as traders balance renewed safe-haven demand against concerns over US government debt, Treasury-market intervention and the Federal Reserve’s interest-rate outlook.
The US Dollar Index (DXY) rose around 0.2% to approximately 99.00 during Monday’s session, recovering from levels near 98.80 earlier in the day. Safe-haven demand strengthened ahead of new US sanctions against Iran, helping the greenback recover despite falling Treasury yields.
The rebound, however, follows considerable weakness. DXY fell nearly 1% last week, while Friday’s trading left the currency near its lowest levels since May.
For currency traders, the key question is whether today’s move represents the beginning of a sustainable dollar recovery, or simply a temporary rebound within a broader period of weakness.
Why Has the US Dollar Index Been Under Pressure?
The dollar’s recent decline has an unusual source: concerns about the US Treasury market.
Last week, after the 30-year Treasury yield approached levels not seen in nearly two decades, the US Treasury announced that it would double its purchases of longer-dated government securities to $4 billion per operation.
The intervention initially supported bonds and lowered yields, but it also unsettled currency investors.
Traders increasingly interpreted the Treasury’s actions as evidence that Washington is uncomfortable with high long-term borrowing costs. That raised questions about fiscal credibility and whether policymakers could increasingly intervene to suppress yields.
Reuters noted that although $4 billion is relatively small compared with the roughly $32 trillion Treasury market, the interventionist signal itself was enough to pressure the dollar.
This helps explain an unusual recent development: the dollar has struggled even during periods when US yields remained relatively high.
US Dollar Index Gains as Iran Risks Boost Safe-Haven Demand
Monday’s recovery has been driven partly by geopolitical risk.
US Treasury Secretary Scott Bessent is preparing a major new sanctions offensive against Iran, targeting Tehran’s international trade relationships. Iran has threatened retaliation, including measures that could affect oil exports from the Gulf if economic pressure intensifies.
The prospect of escalating confrontation has generated renewed demand for safe-haven assets, including the dollar.
DXY climbed approximately 0.2% to 99.00, even as Treasury yields declined.
This divergence is important.
Normally, falling Treasury yields would reduce the attractiveness of dollar-denominated assets and pressure the currency. Monday’s ability to rise despite lower yields indicates that geopolitical safe-haven demand is temporarily outweighing the negative rate effect.
Whether that continues will depend partly on the severity of the new sanctions and Iran’s response.
Treasury Yields Fall While the Dollar Rises
The US bond market remains one of the most important variables for currency traders.
The benchmark 10-year Treasury yield declined approximately 2.8 basis points to 4.709%, while the 30-year yield fell about 2.6 basis points to 5.249% on Monday.
Lower oil prices contributed to the decline, while traders also continued speculating that the Treasury could take further action to contain elevated long-term borrowing costs.
Under normal circumstances, declining yields could be bearish for the dollar.
But the current relationship has become more complicated because investors are simultaneously weighing US fiscal risks, Treasury intervention and geopolitical uncertainty.
Pimco strategists highlighted rising sovereign debt, AI-related corporate borrowing and persistent inflation risks as factors that could keep global bond markets volatile.
For dollar traders, Treasury-market developments therefore remain crucial.
Dollar Remains Weak Against Several Major Currencies
Despite Monday’s rebound, recent dollar weakness remains visible across major currency pairs.
The euro traded around $1.1664, remaining close to the three-month high reached last week, while sterling stood near $1.3627, not far from Friday’s six-month peak of $1.3675.
The Japanese yen traded around 159.21 per dollar.
Meanwhile, China’s yuan remained near a three-and-a-half-year high, with the dollar around 6.72 yuan after the Chinese currency recorded an eighth consecutive weekly gain.
The Canadian dollar was an exception. It weakened to approximately C$1.384 per US dollar after US-Canada trade negotiations collapsed and both countries imposed substantial tariffs.
These moves underline an important point: Monday’s dollar recovery has not yet reversed the broader weakness seen over recent sessions.
Fed Rate Expectations Remain Critical for the Dollar
Federal Reserve policy remains another major driver.
Markets currently assign approximately a 63% probability that the Fed will leave rates unchanged at 3.50%–3.75% at its September meeting, while roughly 37% probability is assigned to a 25-basis-point increase.
Those expectations have changed substantially following softer US labor-market and inflation data.
Recent employment figures showed weaker hiring, while inflation reports have provided some evidence that price pressures are moderating.
However, last week’s FOMC Meeting Minutes showed that many policymakers remained concerned about inflation and that further tightening could become necessary if inflation fails to decline.
This creates two competing scenarios for the dollar:
More hawkish Fed expectations → potentially higher yields → stronger dollar
Fed remains on hold as the economy slows → potentially lower yields → weaker dollar
The balance between these scenarios will likely remain a central driver of DXY.
Gold and Bitcoin Reflect Concerns About the Dollar
One of the clearest signs of recent dollar anxiety has been the strength of alternative assets.
The dollar recorded its largest weekly decline against Bitcoin in nearly three and a half years, while gold has also risen sharply against the US currency.
Gold’s rise has been particularly significant because bullion has advanced even while long-term Treasury yields remain historically elevated.
Some investors appear to be using gold and Bitcoin as alternatives amid concerns about government debt, fiscal deficits and potential attempts to control long-term yields.
Marc Ostwald of ADM Investor Services told Reuters that fears surrounding deficits and policy intervention were encouraging investors to diversify toward gold and Bitcoin.
For dollar traders, continued strength in these assets could therefore provide an important signal about confidence in the greenback.
Jackson Hole Could Determine the Dollar’s Next Major Move
Attention now turns toward the Jackson Hole Economic Symposium, where Federal Reserve Chair Kevin Warsh is expected to provide important clues about monetary policy.
Markets will be watching closely for any indication of whether the Fed remains prepared to raise rates again following July’s hawkish policy debate.
If Warsh emphasizes persistent inflation risks and keeps another hike firmly on the table, the dollar could receive support as traders increase expectations for tighter policy.
A more cautious message emphasizing weaker employment and slowing economic activity could have the opposite effect.
Upcoming US inflation data will also be critical, particularly because the Fed continues to emphasize that future decisions will depend heavily on incoming economic information.
US Dollar Index: What Traders Should Watch Next
The US Dollar Index has recovered toward 99.00, but the broader outlook remains unusually uncertain.
Safe-haven demand surrounding escalating US-Iran tensions is supporting the greenback Monday, while lower oil prices and falling Treasury yields are creating competing pressures.
The bigger issue remains confidence in US fiscal and monetary policy.
The Treasury’s expanded bond-buyback program contributed to the dollar’s sharp decline last week, while the prospect of further intervention continues to make traders cautious. At the same time, uncertainty over whether the Federal Reserve will raise rates again leaves the dollar highly sensitive to economic data.
For traders, the most important factors to monitor are DXY around 99.00, the 10-year and 30-year Treasury yields, US-Iran developments, Fed rate expectations and Kevin Warsh’s Jackson Hole remarks.
A sustained move above 99 could signal that safe-haven demand is beginning to stabilize the greenback. But if fiscal concerns regain control and DXY falls back through its recent lows around 98.5, the broader dollar decline could resume.
For now, the dollar is recovering, but it has yet to prove that the weakness that pushed it toward multi-month lows has run its course.
