The Calendar Changed. The Market Regime Did Not.
What’s happening: Q4 opened as a continuation of Q3. Global sovereign bonds extended their selloff, the US 10-year Treasury yield rose to around 5.34%, the Dollar pushed higher after a sixth consecutive quarterly gain, and EUR/USD broke below 1.13. This came even though softer August PCE inflation had already reduced conviction in another Fed hike in October.
Why it matters: The long end refused to rally on softer inflation data, which makes the 10-year Treasury yield, not the Fed calendar, the cleaner real-time signal for the Dollar. Renewed fuel-supply stress, with Brent back above USD 100, keeps that inflation-and-yield loop alive. Today’s US ISM Manufacturing report and Friday’s NFP are therefore the first tests of whether the Q3 regime can be interrupted.
Within hours of the fourth quarter opening, the dominant themes of Q3 had reasserted themselves. Global sovereign bonds extended their selloff, the Dollar pushed higher, EUR/USD broke below 1.13, and renewed fuel-supply stress kept the inflation backdrop uncomfortable. Even AUD, despite rebounding on the day, remained the weakest major currency over the broader weekly horizon.
The significance is less that these trends survived September than that the quarter boundary produced no reset whatsoever. Q4 has so far opened as a continuity trade. That makes today’s US ISM Manufacturing report the first meaningful test of whether the Q3 regime can finally be interrupted, with Friday’s payrolls report providing the larger test still ahead.
Bond Selloff Crosses the Quarter Boundary
The bond market remains the central driver.
Global Yield Snapshot
- US 10-year Treasury yield: around 5.34% earlier in the day, its highest level since 2002
- US 10-year Treasury yield, Q3: largest quarterly rise since 1994
- Britain 30-year yield: touched 6% for the first time since 1998
- French borrowing costs: pushed to multi-year extremes
- Japanese yields: remained around multi-decade highs
The selloff remained global rather than US-specific, and that matters because the forces behind the move are broader than the next central-bank meeting. Markets are pricing a combination of persistent inflation risk, heavy sovereign borrowing, fiscal strain, large capital demands from AI and defence investment, and a diminished willingness to hold long-duration debt at lower yields. The global rise in borrowing costs is also increasingly threatening government finances as well as equities and credit.
The most revealing US signal came before the new quarter even began. Softer August PCE inflation reduced conviction in another Fed hike in October, yet the long end refused to rally. Instead, the 10-year yield pushed through 5.3%.
Fed timing has become less aggressive. Long-term financial conditions have not.
Dollar Still Trades the 10-Year More Than the Fed Calendar
That distinction continues to support the Dollar.
Dollar Data Points
- DXY: sixth consecutive quarterly gain entering Q4
- DXY: extended higher as Treasury yields climbed again
- Dollar Index: near its strongest level since mid-May
The rise in long-term US yields is outweighing the reduction in immediate Fed-hike expectations. The mechanism is the same one that limited Gold’s reaction to softer PCE a day earlier.
The market can simultaneously price less urgency from Fed officials and demand a higher yield to own longer-dated US debt. As long as the second force dominates, the Dollar retains support even without a fresh increase in October-hike pricing.
That makes the 10-year Treasury yield a cleaner real-time Dollar signal than the precise probability attached to the next FOMC meeting. For Q4 to begin differently from Q3, that relationship probably needs to break.
Euro Breaks 1.13 as Structural Pressures Persist
The Euro provided the clearest FX extension of the Q3 trend.
EUR/USD Data Points
- EUR/USD: dropped through 1.13 for the first time since May 2025
- EUR/USD, September: decline of nearly 2.5%, the largest monthly fall since July last year
The combination of higher energy costs, rising European bond yields and political uncertainty continues to act as a headwind.
The energy channel remains particularly important. Europe is a net importer facing renewed pressure from crude and refined-product prices just as inflation concerns are rebuilding. At the same time, fiscal concerns have pushed French yields sharply higher, while German bonds have not escaped the wider global selloff.
That leaves the Euro caught between higher domestic borrowing costs and a terms-of-trade disadvantage from expensive imported energy.
The move should not be overstated as uniform Euro weakness against every major currency, however. Intraday cross-performance has been mixed. The more durable signal is EUR/USD itself and the broader September decline. The break of 1.13 therefore matters more than any single-session heat map.
Oil Keeps Feeding the Inflation-Yield Loop
Oil and refined fuels provide the connective mechanism between the rates and FX stories.
Fuel Supply Data
- Brent: moved back above USD 100 as global fuel-supply concerns intensified
- China: refiners suspended exports of oil products beyond Hong Kong and Macau from October
- US request to the EU: release of 120mn barrels of emergency diesel over six months
- Germany and France: hold more than a third of the bloc’s strategic diesel reserves
Chinese refiners are prioritising domestic supply, potentially removing an important source of diesel, jet fuel and gasoline from already tight international markets. The strain has also moved into strategic stockpiles. The Trump administration has pressed Germany and France to release emergency diesel stocks, with one source saying Washington requested the 120mn-barrel EU release.
This should not be treated as a separate geopolitical sidebar. It feeds directly into the bond story.
Restricted fuel supply keeps inflation risk alive; persistent inflation risk keeps pressure on long-duration bonds; higher long yields reinforce Dollar strength and squeeze energy-importing economies.
That is the same mechanism that carried markets through much of Q3, and it has reappeared almost immediately in Q4.
ISM Is the First Test of the Script
The first opportunity to disrupt that pattern comes with today’s US ISM Manufacturing report.
A firm reading would reinforce the existing configuration: resilient US activity alongside persistent energy and inflation risks, giving the long end another reason to stay under pressure and Dollar another source of support.
A weak number would be more interesting, but only if the rates market reacts.
After softer PCE failed to push the 10-year yield sustainably lower, simply missing an economic forecast may no longer be enough. A genuine change in the Q3 script would require weaker data to translate into lower long yields.
Friday’s NFP report then becomes the larger test.
Until that transmission changes, Q4 has opened with remarkably little evidence of a new regime.
The global bond rout continues. Dollar remains supported. Euro has broken another important level. Fuel stress is still feeding inflation concerns.
Day One offered no evidence of a turn. The calendar changed. The market regime did not.

FAQ
Why is the Dollar rising when Fed hike expectations have eased?
The market can price less urgency from Fed officials while still demanding a higher yield to own longer-dated US debt. Softer August PCE reduced conviction in another October hike, yet the 10-year Treasury yield pushed through 5.3% and reached around 5.34% on October 1. As long as the long-end yield dominates, the Dollar keeps its support, which is why the 10-year is a cleaner real-time Dollar signal than the probability attached to the next FOMC meeting.
Why did EUR/USD fall below 1.13?
EUR/USD dropped through 1.13 for the first time since May 2025, extending a September decline of nearly 2.5%. Higher energy costs, rising European bond yields and political uncertainty are the main headwinds. The Euro is caught between higher domestic borrowing costs and the terms-of-trade disadvantage of expensive imported energy. The weakness is not uniform against every major currency, so EUR/USD itself and the broader September decline are the more durable signals.
What would show that Q4 is breaking from Q3?
A genuine change would require weaker data to translate into lower long-term yields. A firm US ISM Manufacturing reading would reinforce the current setup, while a weak number matters only if the rates market reacts. Today’s ISM report is the first test, and Friday’s NFP report is the larger one.
Key Takeaways
- Q4 opened as a continuity trade: the bond selloff, Dollar strength, Euro weakness and fuel-supply stress all carried over from Q3 with no reset at the quarter boundary.
- The US 10-year Treasury yield climbed to around 5.34% earlier in the day, its highest level since 2002, and the selloff is global, spanning France, Britain and Japan.
- Softer August PCE reduced conviction in an October Fed hike, but the long end did not rally: Fed timing has become less aggressive while long-term financial conditions have not.
- The Dollar extended higher after a sixth consecutive quarterly gain, trading the 10-year yield more than the Fed calendar.
- EUR/USD broke below 1.13 for the first time since May 2025, squeezed between higher domestic borrowing costs and expensive imported energy.
- Brent above USD 100 and tightening fuel supply keep the inflation, bond-yield and Dollar loop intact.
- Breaking the Q3 script requires weaker data to translate into lower long yields.
What to Watch Next
Today’s US ISM Manufacturing report is the first test of the Q3 regime. A firm reading would reinforce the current setup, while a weak number matters only if long-term yields respond. Friday’s NFP report is the larger test still ahead.
Beyond the data, watch whether the US 10-year yield can fall back from the 5.3% area on weaker numbers, whether EUR/USD can recover the 1.13 level it just lost, and whether fuel-supply stress eases, with Brent back above USD 100, Chinese product-export curbs from October and the US request for an EU diesel release all in play. Until those relationships change, the market regime has not.
