Weekly Sentiment: Diesel Leads Oil, Long End Whipsaws, Euro at 17-Month Low

The fourth quarter opened with a tape that refused to settle into one regime. Core bonds sold off hard into the quarter turn, then reversed as buyers stepped back into Treasuries on Thursday. Energy strength came from the refined end of the barrel rather than crude. Equity indices sat close to record territory while the median stock underperformed. If you were looking for a single risk-on or risk-off label this week, the market did not offer one — it offered three separate threads, each with its own driver, moving at different speeds.

Here is what we observed across those threads, and why the market read them the way it did.

Diesel, not crude, set the energy tape this week

The meaningful energy story was distillate, not Brent or WTI. Chinese refiners suspended most refined fuel exports for October as domestic supply was prioritised, removing diesel, gasoline and jet fuel barrels from an already constrained market. PetroChina cancelled gasoline and diesel cargoes. Separately, restrictions on US diesel flows to Europe moved from background chatter into active discussion, with European emergency stockpiles cited as the pressure point.

What made this different from the crude-led moves of prior weeks is that the crude supply picture actually loosened. Middle East crude exports hit their highest September level since the regional conflict began, according to shipping and commodity data cited this week. Venezuelan exports fell close to 9% in September to roughly 1.08 million barrels per day — but the stated cause was tanker economics and discounting, not wellhead supply.

So crude availability improved while product availability tightened. The market read this as a refining-margin story. Traders watching USOIL alone would have seen a less dramatic week than those tracking distillate cracks, and the dispersion between the two is where the volatility actually lived. Downstream, the pass-through conversation had already started — coverage this week ran through how a sustained diesel premium filters into grocery, apparel and appliance costs, which is a fundamentals input for consumer-facing equities and for the inflation prints on next week's docket.

Why it mattered for positioning: energy exposure taken through crude benchmarks did not capture the week's dominant energy move. That divergence is worth noting in any end-of-week review of what actually drove P&L.

The long end delivered two opposite tapes inside four sessions

The quarter opened with another core bond selloff, particularly at the long end. In the UK, the 30-year tenor pushed past the 6% level — a round number that tends to draw attention regardless of what the underlying fundamentals say. US yields printed fresh 24-year highs in the same stretch.

Then, around Thursday's Wall Street open, it reversed. Yields fell sharply as buyers re-engaged with Treasuries, described in coverage as a tug of war rather than a clean directional shift. That framing is accurate: neither side of the auction-and-flow equation resolved this week.

The cross-asset read was immediate. Bitcoin price action, which had been fighting to hold a local sequence of higher lows, firmed as the yield move faded — a clean illustration of how long-duration risk assets have been trading off real-rate moves rather than off crypto-native catalysts. We observed the same sensitivity in rate-geared equity sectors.

For traders, the practical consequence of a two-way long end is margin and gap behaviour, not direction. When a 30-year tenor moves through a psychological level and then retraces inside the same week, intraday ranges widen across FX and index CFDs even when the weekly close looks unremarkable. Position sizing calibrated to a quiet weekly range would have been mis-sized for the daily ranges inside it.

The euro absorbed the energy bill

EUR/USD fell to a 17-month low on Thursday, breaking to its weakest level since late May 2025. The drivers cited were a stack rather than a single catalyst: the inflationary impact of higher energy costs on an already soft bloc economy, broad dollar strength, and uncertainty that kept risk premium elevated.

The sequencing matters. Europe is the region most directly exposed to the distillate squeeze described above, and the currency took the adjustment. That is the textbook terms-of-trade channel working in real time — an energy importer facing a product-price shock sees it expressed in the exchange rate before it shows in the data.

The data arrives Friday. Euro area flash inflation is scheduled for 09:00 GMT+3, with headline forecast at 3.6% year-on-year against 3.2% prior and core at 2.5% against 2.4%. A headline acceleration of that size, if it lands near forecast, would be the first hard confirmation of the energy pass-through the currency has already been pricing.

We also noted MiCA-review activity on the European side this week — submissions on perpetuals classification under MiFID II, stablecoin reserve requirements, and a 50,000-signature campaign on stablecoin rewards restrictions. None of this moved prices, but it is the regulatory pipeline that shapes European digital-asset market structure over the next cycle.

Index strength masked stock-level churn

The S&P 500 traded just shy of record territory while most individual constituents struggled — a breadth divergence documented in detail this week. That is a concentration signal, and it has a mechanical dimension too: index reshuffles matter more when index-level flows dominate. Twilio's addition to the S&P 500 landed this week alongside the pending Warner Bros Discovery–Paramount merger that vacated a slot.

Underneath, the power-and-electrification theme kept absorbing capital. Amazon secured a 20-year nuclear supply agreement with Constellation. The IEA's framing of rising electricity demand — driven by data centres, electrification and industrialisation — was echoed in sell-side notes on solar and copper, and in reporting on China's 2030 solid-state battery commercialisation target. This is now a multi-asset theme touching equities, industrial metals and energy simultaneously, which is why it keeps surfacing in cross-asset flow discussions rather than staying a single-sector story.

Looking ahead: payrolls and a Fed speaker close the week

The immediate catalyst is US non-farm payrolls at 12:30 GMT+3 on Friday 2 October, forecast at 90K against 162K prior, with the unemployment rate forecast unchanged at 4.1% and average hourly earnings at 3.2% year-on-year. A near-halving of the headline forecast makes this a wide-distribution print, and the long end's two-way behaviour this week suggests limited consensus on how it will be absorbed. Fed Logan speaks at 14:00 GMT+3, roughly ninety minutes after the data — a sequence that has historically produced a second impulse once the initial reaction has run.

Traders holding positions through both events should be aware that scheduled high-importance releases compress liquidity around the print. Our execution is fully automated with no requotes, no filtering by profitability and symmetric slippage — meaning fills around data events reflect available market liquidity in both directions.
