The US dollar moved to a more than three-month high on October 1, 2026, as higher US Treasury yields gave fresh support to the currency. The Dollar Index, or DXY, reached 101.66, its highest level since June 25. The move came even after fresh US inflation data reduced some bets on a Federal Reserve rate hike this month.
The dollar has gained strong support from the bond market. US Treasury yields have moved much higher as investors deal with concerns about inflation, government debt, new bond supply and higher energy costs. These factors have created a strong demand for the US currency.
The latest move shows an important point in the foreign exchange market. The dollar does not always need a higher Fed rate outlook to gain strength. At present, the level of long-term US Treasury yields has a major role in the currency market.
US Treasury Yields Give the Dollar Support
US Treasury yields have become one of the main forces behind the dollar’s latest rise. On October 1, the yield on the 10-year US Treasury note reached 5.342%. That was the highest level since early 2002. The move came as the global bond market faced a sharp selloff.
A higher bond yield can make US assets more attractive to investors who seek higher returns. This can create more demand for the dollar because many global investors need US dollars to buy US bonds and other dollar-based assets.
The recent bond move also reflects wider concerns. Investors face higher oil prices, large government borrowing needs and fresh worries about inflation. These issues have pushed yields higher in several major markets, not just the United States.
The rise in the 10-year Treasury yield is especially important because this rate has a major effect on global financial markets. It can affect loans, bonds, stocks and currency values across many countries.
Inflation Data Gives a Mixed Signal
The latest US inflation data did not give a clear reason for a stronger dollar on its own. US core Personal Consumption Expenditures, or core PCE, rose 3% on a yearly basis in August. The figure was below the market expectation of 3.3%.
This result reduced some expectations for a Federal Reserve rate hike in October. A lower inflation result usually reduces pressure on the central bank to raise rates at once.
Yet the dollar still gained ground.
The reason is that the currency market paid more attention to the rise in long-term Treasury yields and wider inflation risks. The market also received support from comments that inflation pressure has not gone away.
This mix has made the dollar story more complex. Short-term rate expectations have eased, but long-term bond yields have moved higher. As a result, the dollar has kept its strength even after softer US inflation data.
DXY Touches 101.66
The Dollar Index is one of the main measures of US dollar strength. It tracks the dollar against a group of major currencies.
On October 1, the DXY reached 101.66. This was its highest level since June 25. The index had also gained about 2% in September.
The September move was important because it showed a clear change in dollar demand. Investors had faced a mix of inflation worries, bond market pressure and concerns about economic conditions in other major regions.
The dollar also has a safe-haven role. When global markets face higher risk, some investors prefer assets that they see as more liquid and easier to trade. The US dollar often benefits from this type of demand.
The current rise therefore has more than one source. Higher Treasury yields, inflation concerns and demand for the dollar as a major reserve currency have all helped the greenback.
Euro Falls to a 17-Month Low
The euro has faced strong pressure against the US dollar. On October 1, the euro fell below $1.13 for the first time since May 2025. It later traded close to $1.1317 in the Asian session.
The euro also had a weak September. It lost almost 2.5% against the dollar last month. This was its largest monthly fall since July 2025.
Several issues have hurt the euro. Europe faces higher energy costs, concerns about government finances and political uncertainty. Higher oil prices can also create a problem for Europe because the region depends heavily on imported energy.
The contrast with the United States has helped the dollar. US Treasury yields remain high, while investors have faced new concerns about European bonds and government debt.
The result is a weaker EUR/USD rate. A lower EUR/USD value means that one euro buys fewer US dollars.
Yen Remains Under Pressure
The Japanese yen has also weakened against the dollar. USD/JPY rose to about 158.29 on October 1, according to Reuters. Another market report placed the pair near 158.15.
The move is important because the yen remains close to levels that have caused concern in Japan. A weak yen raises the cost of imported goods, especially energy and raw materials.
At the same time, the market remains alert to possible action from Japanese authorities. The memory of past currency intervention has made traders more careful as USD/JPY moves close to the 158 area.
The Bank of Japan also remains a key factor. A summary of views from its September meeting showed that some policymakers saw a need to speed up or bring forward future rate hikes.
Even so, the gap between US and Japanese bond yields remains a major factor for the currency pair. Higher US yields can make dollar assets more attractive compared with Japanese assets.
Pound Also Feels Dollar Pressure
The British pound has not escaped the broad dollar move. GBP/USD was near $1.32495 in early trade on October 1.
Sterling had already lost about 2.1% in September. The stronger dollar has been one reason for that decline.
The pound also faces its own set of market concerns. Global bond pressure can affect UK assets, while higher energy prices can add to inflation concerns.
For the GBP/USD pair, the US side of the story remains very important. If US Treasury yields stay high, the dollar can retain support against the pound.
Australian Dollar Falls
The Australian dollar also came under pressure. AUD/USD fell to about $0.6940, its lowest level in two months.
Part of the pressure came from weaker expectations for another near-term rate hike by the Reserve Bank of Australia. Australian inflation data came in slightly below forecasts, which reduced some rate expectations.
At the same time, higher US Treasury yields made the US dollar more attractive.
This shows how the dollar story can affect currencies far outside Europe and Japan. When US yields rise, currencies such as the Australian dollar can face pressure even when their own economies have local support.
New Zealand Dollar Hits a New Low
The New Zealand dollar faced similar pressure. NZD/USD fell to about $0.5618, its lowest level since November 2025.
The New Zealand dollar is often sensitive to global risk sentiment and interest rate expectations. When investors prefer the US dollar, currencies such as the New Zealand dollar can face a decline.
The latest move also shows the broad nature of the dollar advance. The US currency has gained against several major currencies rather than just one or two.
Global Bond Pressure Matters for Forex
The current forex move cannot be viewed on its own. The bond market is a major part of the story.
Global bonds had one of their worst monthly periods in years in September. Higher government debt, more bond supply and renewed inflation concerns all pushed yields higher.
The US 10-year yield reached 5.342% on October 1. The UK bond market also faced major pressure. The UK 30-year gilt yield moved above 6%, a level not seen since 1998.
Japanese bond yields also moved close to multi-decade highs.
These moves matter for forex because interest rates and bond yields affect the flow of global capital. When investors see higher returns in one market, they may move money toward that market. Currency demand can rise as a result.
Oil Prices Add to Inflation Concerns
Energy prices have added another layer to the market story. Higher oil prices can raise costs for households and companies. They can also make it harder for central banks to control inflation.
For Europe, the issue is more serious because of its high reliance on imported energy. Higher energy costs can hurt the euro if they weaken economic confidence or force the European Central Bank to deal with higher inflation.
For the United States, higher oil prices can also create inflation pressure. That keeps the Federal Reserve in a difficult position.
The market therefore faces a balance between weaker inflation data and fresh price pressure from energy and other costs.
What Traders Will Watch Next
The next major focus will be on US economic data and Federal Reserve comments.
On October 1, markets were set to receive weekly Initial Jobless Claims data and the ISM Manufacturing PMI report for September. Investors were also set to hear from several Federal Reserve and European Central Bank policymakers.
These events can affect expectations for future interest rates.
The market will also watch US payroll data and future inflation reports. These reports can help show whether the Federal Reserve needs to keep rates high for longer or can move toward a softer policy path.
For forex traders, the main question is not only whether the Fed raises rates. The level of US Treasury yields may remain just as important.
What the Dollar Move Means for Forex
The dollar’s move to 101.66 shows that the currency market remains highly sensitive to US bond yields.
A weaker inflation report did not stop the dollar from gaining. The reason was a mix of high long-term yields, global inflation concerns, energy costs and demand for US assets.
The euro remains under pressure near $1.13, while USD/JPY remains close to 158. GBP/USD stays near $1.325, AUD/USD has fallen to around $0.6940, and NZD/USD has dropped to about $0.5618.
The Indian rupee also faced pressure. It fell 0.16% to 95.9850 per dollar on October 1. State-run banks sold dollars, which likely helped limit the rupee’s fall.
A Market Driven by Yields
The main forex story on October 1, 2026, is clear: the US dollar has strong support from the Treasury market.
The DXY reached 101.66, its highest level since June 25. The US 10-year Treasury yield reached 5.342%, its highest level since early 2002. At the same time, the euro fell below $1.13, the yen weakened near 158 per dollar, and several other major currencies also lost ground.
The softer US core PCE result has reduced some near-term rate hike expectations, but it has not removed inflation concerns. Higher oil prices, large government borrowing needs and global bond pressure remain important risks.
For the forex market, the next phase will depend on whether US Treasury yields stay at these high levels and what future US economic data says about inflation, jobs and Federal Reserve policy.
For now, the dollar remains at the center of the global currency market, with bond yields serving as one of its strongest sources of support.
