Key Takeaways
- Sticky US inflation pushed the dollar to a fresh 2026 high as markets brought forward Fed tightening expectations and Treasury yields moved higher.
- The dollar’s breakout now depends on whether Fed officials validate expectations for an October hike, with DXY approaching resistance around 103.
- USD/CAD returned toward 1.425 as the US-Canada two-year yield gap widened, overwhelming the limited support the loonie received from higher oil prices.
- Canada’s weakening labour market leaves the Bank of Canada poorly positioned to match further Fed tightening, keeping the risk of a move above 1.4300 firmly in view.
- USD/MXN’s break above 18.5 signals a deeper carry unwind as rising US yields, Banxico easing expectations and elevated energy risks erode the peso’s rate advantage.
Hot inflation pushes US dollar to new 2026 high
The dollar has climbed to a fresh 2026 high after inflation once again came in stronger than the Fed would like. Headline CPI accelerated to 3.7% year over year as energy costs rose, but the more important signal was a second consecutive 0.3% monthly increase in core prices. Treasury yields moved sharply higher at the front end as markets lifted the probability of an October hike to 45% and moved closer to fully pricing another increase by December.
That repricing has widened the dollar’s rate advantage, particularly against currencies such as the Canadian dollar, where the policy outlook could diverge further by month-end. Weaker equity futures have added some demand for the greenback, while renewed shipping disruptions near the Strait of Hormuz have pushed oil higher. The combination of sticky core inflation, rising energy costs and softer risk appetite leaves the Fed with little room to signal an early shift away from tightening.
The break above the dollar index’s previous 2026 high supports dollar’s five-week rally that otherwise looked running out of momentum. European fiscal pressure remains another source of support, with concerns over France’s budget weighing on the euro and mechanically lifting the heavily euro-weighted index. DXY is now approaching resistance around 103, with the inflation surprise leaving dollar bears little immediate support.
The durability of the breakout now depends on whether Fed officials validate the market’s repricing for October. Chair Warsh has been reluctant to commit to a policy path based on a single inflation report, leaving room for officials to push back against expectations of an immediate hike. That could produce a brief pullback in yields and the dollar, but persistent core inflation and elevated energy risks continue to favour further gains.
Hot US inflation threatens Loonie recovery
The loonie’s two-day recovery faded quickly after the stronger US CPI report pushed USD/CAD back toward 1.425. Higher oil prices and broader US-dollar weakness had offered some relief earlier in the week, but the inflation surprise shifted attention back to relative rates. US two-year yields rose sharply, taking the US-Canada spread toward its cycle high near 160 basis points and restoring the main source of pressure on the Canadian dollar.
That rate gap is difficult to overcome because the two economies are moving in different directions. Canada has lost more than 110,000 jobs over the past two months, leaving the Bank of Canada with little room to follow the Fed if US rates move higher again. The result is a widening policy divide that keeps Canadian yields below their US counterparts and limits the scope for a sustained loonie recovery.
Oil above $105 per barrel provides some terms-of-trade support, but the benefit is less straightforward than usual. Higher crude prices also add to US inflation pressure, reinforcing the Fed’s hawkish stance and widening the yield differential against Canada. Trade frictions and unresolved diplomatic tensions are adding to the Canadian growth concerns, leaving USD/CAD supported even with oil near multi-month highs.
The October 28 central bank decisions will determine whether that divergence widens further. A more hawkish Fed alongside a Bank of Canada hold could push the rate spread wider and take USD/CAD through 1.43. Canada’s upcoming inflation report is the clearest domestic challenge to that outlook. Unless it delivers a meaningful upside surprise, the loonie is likely to remain under pressure.
Peso carry unwinds as USD/MXN breaks higher
The Mexican peso has fallen to new year-to-date lows as the backdrop for its once-attractive carry trade deteriorates. USD/MXN is trading close to its 52-week high at 18.52, removing the technical ceiling that contained the pair during the peso’s earlier strength. Stronger US inflation has pushed Treasury yields higher just as Banxico’s recent guidance keeps the door open to eventual easing, narrowing the rate advantage that had supported the peso.
That leaves Banxico in a difficult position. Trade frictions, geopolitical risks and Mexico’s reliance on imported refined fuels leave inflation vulnerable to higher energy prices, yet the domestic outlook still argues for lower rates. Elevated crude prices also reinforce the Fed’s hawkish stance, adding pressure from both sides of the yield differential. Continued uncertainty over the USMCA outlook has further weakened one of the peso’s main sources of structural support.
Sustained trading above 18.5 opens a path toward 19 as carry positions continue to unwind. A peso recovery would require US yields to retreat, Banxico to push back more firmly against easing expectations or trade uncertainty to recede. Until the rate differential stabilizes or energy pressures ease, the balance of risks for USD/MXN remains tilted higher.
