August Core PCE: The Last Inflation Test Before October FOMC
============================================================

The Fed's preferred inflation gauge is due at 13:30 London today — the final core PCE reading before the 27-28 October FOMC — and the outcome will set the tone for Treasuries, the dollar and European duration into month-end.

![August Core PCE: The Last Inflation Test Before October FOMC](https://assets.simplefx.com/cms/medium_49ada861-8978-41dd-a106-0f5431366670.jpg)

One Number, One Window: PCE Lands Into a Bruised Bond Market
------------------------------------------------------------

August core PCE is scheduled for release at 13:30 London today, arriving at one of the more consequential moments for fixed income in recent memory. Consensus expects a monthly gain of +0.3% on the core measure, with the annual rate seen in a range of roughly 3.3-3.4%. The headline reading is forecast higher, in a +0.4-0.5% monthly range. These are expectations, not outcomes — and the gap between the two will drive the afternoon session.

The stakes are elevated because this is the last core PCE print the Fed will see before the 27-28 October FOMC. Prediction markets currently assign roughly a 68-69% probability to a 25 basis point hike at that meeting. A reading that comes in above the consensus monthly figure would harden that pricing further, extending the global long-end selloff that has already pushed benchmark yields to multi-year highs. A soft print offers duration its only credible near-term relief — but there is a catch.

Annual revisions accompanying today's release may revise the July PCE figure lower by two or three tenths, potentially pulling the 12-month rate toward 3%. If that happens, a seemingly benign annual number could be read as a statistical artefact rather than genuine disinflation. Traders will need to strip out the revision effect quickly and focus on the unrevised monthly momentum to gauge the true signal. A soft headline built on downward revisions to prior months is likely to be dismissed as stale data rather than celebrated as a turning point.

The release lands into a bond market already under severe stress. Ten-year Treasury yields held near their highest level since 2007 during Asian hours on 30 September, with the month of September on course for one of the largest monthly yield rises in roughly two years. The 30-year has climbed above levels not seen since the early 2000s. European duration has moved in sympathy, with Bunds, gilts and BTPs all under pressure. A hotter-than-expected core PCE would extend that selloff into the European close and likely lift the dollar index, weighing on EUR/USD which is already sitting near multi-month lows.

For European equity desks, the transmission is direct: higher long-end yields compress valuations, and energy-intensive sectors face a double squeeze given elevated crude prices. A softer print would offer some relief to rate-sensitive names, though the broader context — energy costs, fiscal stress in France, and a hawkish ECB — limits how far any rally could run on a single data point.

Bond Rout, Crude Risk and French Spread Pressure Set the Stage
--------------------------------------------------------------

The bond selloff deepened after President Trump rejected Iran's latest proposal to reopen the Strait of Hormuz, removing a diplomatic off-ramp that markets had partially priced. Brent crude rallied for a second consecutive session before a reported emergency reserve release pulled prices back. The Hormuz premium is keeping energy costs elevated and hardening global rate expectations — a direct input into today's PCE read.

Separately, French 10-year yields surged to an 18-year high on 30 September, pushing the OAT-Bund spread to its widest since the 2010-2012 euro sovereign debt crisis. Drivers include a widening budget deficit, political fragmentation and proposed spending cuts, with French Senate elections falling in early October. The spread widening is dragging gilts and BTPs with it and adding a political risk premium to the euro.

Jobs Data and Euro-Area Inflation Follow on 2 October
-----------------------------------------------------

If today's PCE lands in line or softer, the next test arrives on 2 October: the US September employment report, where consensus sits at +90k nonfarm payrolls with unemployment at 4.1%. Analysis suggests even a notably weak print may not be sufficient to shift October hike pricing materially. On the same date, Eurostat releases the September flash euro-area HICP, with national readings from Germany, France, Italy and Spain preceding it. A firm core or services component there could harden ECB December hike expectations and put a floor under the euro.

### Risk Factors

*   Revision whipsaw: annual benchmark revisions to prior PCE data could distort the headline annual rate, creating a sharp initial market move that partially reverses once traders adjust for the revision effect.
*   Event-day gap risk: with long-end yields already at multi-year highs and positioning stretched, a surprise in either direction on core PCE could trigger outsized moves in Treasuries and the dollar in thin pre-European-close liquidity.
*   Hormuz headline risk: any fresh development on the US-Iran diplomatic situation — in either direction — could override the PCE signal for crude and risk assets mid-session.
*   OAT contagion: further widening in the French OAT-Bund spread into month-end could amplify any negative reaction in European duration and equities, particularly if the PCE print is hot.
