Key Takeaways
- The dollar has struggled to hold its post-data gains as falling Treasury yields offset strong US inflation and activity figures, pulling DXY back from its 2026 high near 102.9.
- The AI and semiconductor selloff has driven defensive demand into Treasuries, weakening the dollar’s rate advantage as markets shift their focus from an October Fed hike to December.
- The euro has gained little from the dollar’s retreat as rising French yields and persistent fiscal uncertainty continue to limit EUR/USD.
- Hotter Mexican inflation has given the peso some relief by challenging expectations for a November Banxico cut, although its sub-300-basis-point carry spread remains fragile.
AI Treasury bid keeps dollar near support
The dollar is struggling to capitalize on the strongest combination of US inflation and activity data this year as lower Treasury yields offset the initial hawkish repricing. Hotter CPI, PPI and retail sales pushed DXY to a 2026 high of 102.9, but the move quickly faded after Fed Chair Warsh declined to reinforce expectations for an October hike during his Bangkok appearance. The implied probability of a move this month fell from 45% to 14%, shifting the policy debate toward December and removing the dollar’s nearest rate catalyst.
The larger drag has come from the AI and semiconductor selloff, which drove defensive flows into Treasuries and pulled two- and ten-year yields 15 to 18 basis points below their post-CPI highs. That compression weakened the dollar’s rate advantage and outweighed economic data that would normally support the currency. A partial recovery in chipmakers has since helped the ten-year yield stabilize near 5.1%, but the link now cuts both ways. Renewed equity weakness would revive Treasury demand and pressure the dollar, while a more durable stabilization could allow yields and rate differentials to regain control.
Oil and Europe are at the same time limiting the downside. Shipping risks around the Strait of Hormuz continue to support the energy-inflation channel even as crude prices retreat from their recent peak, preserving the case for a December Fed hike. Jobless claims and flash PMIs could shift expectations if they materially challenge the growth outlook, but the October 28 Fed decision remains the next major test of whether policymakers intend to wait until December.
DXY is testing the lower end of its ascending channel near 101.5, with initial resistance around 101.8. December hike pricing near 88% and persistent European fiscal pressure still support the broader dollar outlook. For now, however, the index remains caught between sticky inflation that limits the downside and an AI-driven Treasury bid that caps its recovery.
French 10Y at 5% keeps euro bears in control
EUR/USD closed flat yesterday, with buying interest emerging during Asia trading hours as tech earnings failed to reassure investors about the rebound in the artificial intelligence trade.
Those concerns had weighed modestly on the dollar in recent days. As investors reassessed the growth outlook amid fears of an AI bubble, Treasuries rallied and markets priced in a slightly more dovish path for Federal Reserve policy.
We remain doubtful that AI-related anxiety will prove potent enough to become a distinct bearish force for the dollar.
This is a familiar pattern. Such episodes of anxiety tend to persist until earnings season demonstrates that corporate fundamentals remain resilient, allowing the rally to resume. Whether that resilience ultimately proves durable is another question. But the typically temporary nature of these rotations out of the AI sector should prevent a more lasting reassessment of the long-term growth outlook.
A hawkish Federal Reserve, ongoing geopolitical uncertainty, and France’s fiscal and political challenges remain the dominant headwinds for EUR/USD.
Yesterday, the yield on benchmark French government debt climbed to 5% for the first time since 2002, widening the spread over German Bunds to 159.4 basis points, the largest gap in 15 years.
These moves were driven by a rise in energy prices, with benchmark European natural gas futures gaining around 4% and Brent crude trading near $110 per barrel.
This highlights that France’s fiscal difficulties are also being influenced by external factors, adding another layer of complexity to the outlook. Yield spreads can widen and the euro can weaken even in the absence of fresh developments from budget negotiations. That dynamic gives investors further reason to remain cautious.
Civil unrest across France, coupled with the looming Moody’s sovereign rating review this Friday, should continue to weigh on the euro in the near term. That pessimism, however, is more likely to find expression through crosses such as EUR/CHF or EUR/JPY should the AI theme continue to dominate trading this week.
Hotter inflation offers Peso a fragile reprieve
The Mexican peso has found its first meaningful relief in weeks after Mexico’s early-October inflation report challenged expectations for another Banxico rate cut. USD/MXN retreated from an overnight high of 18.85 toward 18.77 after headline inflation rose 0.41% in the first half of the month, while core prices increased 0.25%, well above the 0.17% forecast. The stronger core reading suggests price pressures extend beyond energy and could produce a more divided policy debate at Banxico’s November 5 meeting.
The peso’s carry support remains fragile. Mexico’s two-year yield near 7.62% leaves its advantage over US Treasuries at roughly 289 basis points, still below the 300-basis-point threshold investors have typically demanded to compensate for peso volatility. Higher oil prices are squeezing that spread from both sides by raising Mexico’s fuel-import costs while reinforcing the Fed’s tightening bias. Unresolved trade negotiations and record bearish institutional positioning add to the pressure, although crowded shorts leave room for a sharp rebound if Banxico turns more hawkish or Washington confirms progress on trade.
USD/MXN traded above its previous 52-week high of 18.69 during the session but has yet to confirm the breakout on a closing basis. The 18.7 area is the first support level on any further peso recovery, while a move below 18.6 would suggest the inflation surprise has materially changed the Banxico outlook. Without a sustained repricing toward a November hold or concrete progress on trade, the damaged carry structure leaves 19.00 in focus.
