Eurozone Inflation Jumps to 3.8% in September, Yet the Euro Stays Near 1.12

Inflation in the euro area rose faster than expected in September. Eurostat's flash estimate, published on Friday 2 October, puts annual inflation at 3.8%, up from 3.2% in August and above the 3.6% that economists had forecast. Energy did most of the damage, with prices up 18.8% on the year.

Normally a beat like this would lift the euro, because hotter inflation raises the chance of another rate hike from the European Central Bank. This time EUR/USD rose briefly towards 1.1270, then slipped back to around 1.1250, just above Thursday's low of 1.1210.

What drove the jump

Energy accounts for almost all of the rise. Annual energy inflation climbed from 14.3% in August to 18.8% in September as crude stayed high on tension around the Strait of Hormuz. Services inflation edged up from 3.0% to 3.2%, and food, alcohol and tobacco rose from 1.1% to 1.4%. Prices of non-energy industrial goods cooled slightly, to 1.1% from 1.2%.

Core inflation, which strips out energy, food, alcohol and tobacco, stood at 2.5%, matching forecasts. That detail explains much of the muted market reaction. The ECB looks closely at the core rate to judge whether energy costs are spreading into wages and wider prices, and so far that spread looks limited.

Which countries saw the highest rates

National figures released earlier in the week had already pointed to a hot print. Germany, France, Italy and Spain all reported September inflation above forecast. Spain hit 5.0%, its highest since 2023, and German harmonised inflation rose to 3.3%, close to a three-year high.

Why the euro did not rally

Three weights are holding the single currency down. US yields keep rising faster than European ones, so the rate gap still favours the dollar. French public finances are under pressure: France's 10-year yield rose more than 70 basis points in September and the spread over German Bunds widened to about 140 basis points, a 14-year high. Energy-driven inflation also hurts growth, because households and factories pay more for power and have less to spend elsewhere.

Markets therefore read the data as bad news dressed up as hawkish news. An ECB hike to fight energy prices could slow an already weak economy, and that prospect does little for the currency.

EUR/USD lost about 0.8% on Thursday alone and is down more than 1% this week. Thursday's 1.1210 marked its weakest point in more than a year.

What the ECB is likely to do next

The ECB raised its deposit rate by 25 basis points to 2.50% on 10 September. Its next meeting is on 29 October, one day after the Fed. September's figures add pressure to tighten again, but policymakers face a hard trade-off: energy prices they cannot control on one side, slowing industry on the other.

ECB staff projections suggest inflation peaks in late 2026 and eases as energy costs fall back, assuming the Middle East conflict does not worsen. If oil stays high into the winter, that forecast will need revising, and the debate over further hikes will intensify.

How energy inflation reaches your trades

Europe imports most of its oil and gas, so every rise in crude sends money out of the region. Importers sell euros to buy dollars and pay for fuel, which adds steady selling pressure on EUR/USD that has nothing to do with interest rates. America produces much of its own energy and feels far less of that drag.

Higher fuel bills also squeeze spending. Families paying more for heating and transport cut back elsewhere, and factories facing higher power costs trim output. Weaker growth makes the ECB more cautious about hiking, even with headline inflation near 4%, and that caution caps any rally in the single currency.

This is why oil headlines from the Gulf now move the euro almost as much as data from Frankfurt. A deal that reopens the Strait of Hormuz would likely ease both inflation and the pressure on the euro. Any fresh flare-up would do the reverse.

EUR/USD levels to watch

• Resistance: 1.1270 (Friday's high), then 1.1325, the June low that now acts as a ceiling, and 1.1350.
• Support: 1.1210 (Thursday's low), then the round number 1.1200.
• Next catalyst: today's US jobs report at 12:30 GMT, which matters more for the pair than Europe's own data this week.

A break below 1.1200 would open the way for a deeper slide, especially if US payrolls surprise on the upside. By contrast, a weak US report could lift the pair back towards 1.1325. See our daily EUR/USD analysis for intraday levels and trade plans.

What this means for traders

• Treat energy prices as a driver of EUR/USD. Sharp moves in Brent crude often show up in the pair within hours.
• Expect the euro to react more to US data than to its own releases while the US rate advantage stays wide.
• Watch French bond spreads. A further jump above 140 basis points would signal fresh stress for the currency.
• Mark 29 October in your calendar. A hawkish ECB surprise could squeeze traders who are short the euro.

None of this guarantees a further fall. Positioning against the euro is already heavy after a weak September, and crowded trades can unwind quickly when data turns. Keep risk small until the pair shows which way it will break from the 1.1200 to 1.1325 range.
