Eurozone inflation at 3.8% is still an energy shock, and markets expect the ECB to wait past October

Euro-area annual inflation was 3.8 per cent in September, according to Eurostat's flash estimate published on 2 October, up from 3.2 per cent in August. The figure landed three weeks after the European Central Bank's second rate increase of the cycle and four weeks before the Governing Council meets again on 28-29 October. On Eurostat's own breakdown it is almost entirely an energy number, which is why the market reading of the October meeting is not the one the headline implies.

What the flash estimate said

Eurostat put energy inflation at 18.8 per cent year on year, against 14.3 per cent in August. Services rose to 3.2 per cent from 3.0, food, alcohol and tobacco to 1.4 from 1.1, and non-energy industrial goods edged down to 1.1 from 1.2. The monthly all-items rate was 0.6 per cent.

The underlying measures need naming precisely, because the release publishes three and they do not agree. Eurostat's "all-items excluding energy, food, alcohol & tobacco" — the aggregate normally reported as core — was 2.5 per cent, up from 2.4 per cent. "All-items excluding energy" was 2.3 per cent, up from 2.1 per cent, and "all-items excluding energy and unprocessed food" was 2.2 per cent, up from 2.1 per cent. All three are rising; none is far from the 2 per cent target. Euronews, working from the same release, calculated that energy contributed roughly 1.7 percentage points of the 3.8 per cent headline, close to half of it.

Dispersion across the union is wide. Eurostat's country estimates run from 2.4 per cent in Malta and 2.6 in Finland up to 5.1 in Greece, 5.2 in Cyprus and Luxembourg and 6.1 in Lithuania. Germany was 3.3 per cent, France 3.4, Italy 4.1 and Spain 5.0. One policy rate is being set against national rates differing by a factor of two and a half.

The ECB's position, and what it has not said

On 10 September the Governing Council raised all three key rates by 25 basis points, to 2.50 per cent on the deposit facility, 2.65 per cent on the main refinancing operations and 2.90 per cent on the marginal lending facility, with effect from 16 September. That followed 11 June, which took the deposit rate to 2.25 per cent; both times the ECB's stated reason was the inflationary pressure generated by the war in the Middle East. The September decision was unanimous.

The September staff projections put headline inflation at 3.0 per cent in 2026, 2.5 per cent in 2027 and 2.1 per cent in 2028, the last two revised up from June, with growth at 0.9, 1.4 and 1.5 per cent, revised up across the horizon. Christine Lagarde offered nothing beyond the framework: "We are not pre-committing to a particular rate path," and, on the next meeting, "We have not actually debated at all any kind of future path."

Isabel Schnabel made the hawkish case in Luxembourg on 30 September. The new shock, she argued, "hit while the disinflation process was still in motion"; household inflation expectations "moved up and continue to stand above pre-conflict levels"; and "if policymakers waited for firms to visibly raise prices and wage negotiations to conclude, they would be acting too late." She defended the record plainly — "Raising interest rates twice since June was an appropriate policy decision" — while conceding that long-term expectations "remain in the vicinity of our 2% target".

Sovereign spreads, where France is now the pressure point

Bond markets are tightening conditions independently, but not where the euro-crisis template would predict. Il Sole 24 Ore reported the ten-year BTP-Bund spread opening at 123 basis points on 2 October, the widest since April 2025, after closing at 118 on 1 October, up 16 basis points in a day; the ten-year BTP yielded 4.70 per cent and the Bund 3.47 per cent, the Bund falling as money moved into it. The paper attributed the widening to energy-market tension and to contagion from French paper, which investors now treat as riskier than Italian debt.

The French figures bear that out. Euronews reported the ten-year OAT at 4.96 per cent on 1 October, the highest since July 2002, and the France-Germany spread above 140 basis points, the widest since 2012, after a 2027 budget showing public debt at 119 per cent of GDP and planned borrowing of €340 billion. Deutsche Bank's Jim Reid said the daily moves "were reminiscent of the Euro crisis in many respects, with sovereign contagion a big talking point."

Olli Rehn drew the policy conclusion on 2 October. Higher energy prices "bring us closer to the ECB's adverse scenario in terms of inflation", he said, but "the rise in long-term interest rates will slow growth and reduce the pass-through of the energy shock to other prices and wages". Reuters put Germany's ten-year borrowing cost at 3.57 per cent, a 17-year high, against 5.32 per cent on the US equivalent. The currency does not help: the ECB's euro reference rate was $1.1225 on 2 October, from $1.1298 the day before, and a softer euro raises the local price of dollar-denominated energy.

Which way the next move goes

A near-certain October increase does not survive contact with the pricing. Reuters reported on 2 October that the odds of an October hike were negligible and that the next increase is not fully priced until January, with investors anticipating up to three further rises over the coming year. Jack Allen-Reynolds of Capital Economics said September's data "don't alter our view that the ECB is most likely to wait until December to raise interest rates again. That said, if energy prices rose further in the next few weeks, an October hike would not be a big surprise." Euronews, the same day, reported prediction markets assigning a 91 per cent chance of a hike at the end of the month. The two cannot be reconciled; the gap between a thin prediction market and money-market pricing is worth flagging rather than averaging away.

The case for waiting is Rehn's: the excluding-energy aggregates sit between 2.2 and 2.5 per cent, and long yields are doing part of the tightening unbidden. The case against is Schnabel's: expectations have already moved, and a central bank that waits for confirmation in prices and wages acts too late.

What to watch

• The 29 October decision: whether the deposit rate moves to 2.75 per cent, and whether September's unanimity survives a contested meeting.
• Eurostat's final September release and the October flash: whether the excluding-energy aggregates keep climbing, which would make this more than an energy shock.
• French rather than Italian spreads: a France-Germany gap wider than Italy's inverts the usual map of euro-area credit risk.
• Energy prices over the next few weeks, the condition Allen-Reynolds set for an October move becoming likely.
