The dollar remains near three-month lows even as US real yields climb. The 10-year real yield has risen about 70 basis points from its 18-month low, while DXY is trading around 99. Similar real-rate moves generated considerably more dollar strength in 2018 and 2022. The weaker response now suggests that investors are separating the return available on Treasuries from their broader assessment of US policy risk.
The latest Treasury buyback announcement highlighted that distinction. The expansion of long-end operations beginning September 9 briefly pulled yields lower, but much of the move in the 30-year was subsequently reversed. The program may ease pressure in less-liquid securities and improve execution at the long end, but it does not alter the volume of debt the private sector must ultimately finance. It may also complicate the market signal by introducing another policy influence over long-term borrowing costs.
The rise in yields should not be interpreted solely as a fiscal revolt. The expected path of monetary policy has also shifted higher as the economy continues to absorb restrictive rates, inflation remains above target and expectations for near-term easing fade.
Under a scenario in which the nominal equilibrium policy rate is around 3.7%, a 10-year yield in the high-4% range is economically plausible. The San Francisco Fed’s model decomposition supports that broad interpretation: on August 21, its model divided a 4.81% 10-year yield into a 3.45% average expected overnight rate and a 1.36% term-premium component. Current valuations therefore reflect a meaningful reassessment of the future policy path, not just concern over federal borrowing.
The buyer base is also becoming less supportive. Last week, we argued that Uncle Sam is now competing with deep-pocketed tech giants for global capital. The Dallas Fed estimates that AI-related investment-grade issuance could reach $300 billion in 2026 and generate as much as $360 billion in 10-year-equivalent duration supply, or about one-eighth of the duration supplied by Treasury issuance.
At the same time, higher Japanese yields also improve the relative appeal of domestic assets for Japanese institutions, particularly after accounting for hedging costs and currency exposure. Neither development implies an abrupt withdrawal from Treasuries, but both reduce the certainty that historical sources of demand will absorb additional US issuance on the same terms.
This changing mix helps explain the dollar’s unusual behaviour. Higher US yields still offer carry and may establish a floor under the currency, but the composition of the increase is becoming less supportive. A rise driven by economic outperformance and a credible monetary response normally strengthens the dollar. A rise that also includes compensation for fiscal uncertainty, supply absorption and unpredictable policy intervention has a less straightforward FX impact.
Trade and geopolitical tensions add further crosscurrents and narrative volatility. The collapse of US-Canada trade talks threatens regional growth, while tougher Iran sanctions could lift oil prices and oil-linked dollar demand. The PCE report on Wednesday and Jackson Hole on Friday may decide whether DXY breaks below 98.80 or recovers toward 100. Until the US policy premium narrows, however, rallies toward 100 should remain tactical and vulnerable to reversal.
USD/CAD has jumped to 1.3852 from last Thursday’s cycle low of 1.3760 as the trade dispute returns with greater force. Talks collapsed after the final text reportedly differed from Canada’s understanding of the agreement. The US then imposed 50% tariffs on about $20 billions of Canadian goods, prompting Canada to announce equal counter-tariffs from September 8. A further threat to raise tariffs on Canadian autos, parts and steel to 50% from January 2027 has widened the economic risk.
The escalation has quickly weakened Canada’s improving macro-outlook. The Canadian two-year yield has fallen to 2.94%, widening its gap with the US equivalent to about 129 basis points. Markets are now questioning whether the Bank of Canada can raise its policy rate toward 3% by July 2027. Federal support may cushion affected firms and workers, but it cannot fully protect investment, employment or supply chains from a prolonged tariff regime.
This shift has also reversed the technical picture for USD/CAD. The pair had declined 2.6% from its July high of 1.4125 as strong Canadian data and trade optimism supported the loonie. That move is now unwinding, with 1.39 emerging as the first major resistance level. A sustained break above it would strengthen the case for a move toward 1.40 to 1.41 as markets price a longer and more damaging dispute.
The January auto tariff threat presents the largest forward risk because components often cross the border several times before final assembly. US PCE on Wednesday and Jackson Hole on Friday, could provide some relief through broader US dollar weakness, but Canadian trade risks will continue to drive the pair. Renewed negotiations before the September 8 deadline could trigger a sharp CAD recovery. Without a credible path back to talks, however, rallies in the Loonie are likely to struggle and USD/CAD will remain biased toward 1.40.
USD/MXN is trading near 16.96, close to its strongest level since May 2024, despite rising geopolitical risk. Second-quarter GDP rebounded by 1.4%, and inflation moved above Banxico’s target midpoint. These conditions support a prolonged rate hold and preserve the peso’s carry appeal.
Mexico’s yield advantage remains the main source of peso strength. The two-year yield offers a premium of about 293 basis points over the US, while the long-end spread remains close to 250 basis points. Banxico’s unanimous hold at 6.50% and delayed inflation convergence forecast suggest that this advantage will persist. Strong reserves, nearshoring investment and AI-related exports add further support, even as global equity sentiment weakens.
USD/MXN is now testing support near 16.90 after breaking through several key levels since its July peak. A sustained move lower would expose 16.80, although crowded peso positioning raises the risk of a sharp reversal. China’s response to Iran sanctions, US PCE on Wednesday and Jackson Hole on Friday are the main near-term catalysts, while a wider North American trade conflict could introduce fresh pressure. Carry and technical momentum favour the peso, but any shock that forces investors to cut risk could send USD/MXN higher.
