Ordinary Ledger: one receipt, three different stories

Germany’s inflation rate is a single number, and it is a useful one. In September Eurostat’s harmonised index put it at 3.3%, up from 2.0% in February¹. But nobody pays an average. You pay a fuel bill, a supermarket bill and an energy bill, and this autumn those three lines are telling three different stories. On the day the European Central Bank meets, it is worth reading them one at a time.

The pump. Fuels for the car cost 36.8% more in September than a year earlier, the highest reading since at least the start of 2025¹. Before the war began in late February the same line was rising by 0.4% a year; by March it was up 19.8%¹. The ADAC’s figures from Wednesday show where it stands now: a litre of Super E10 at €2.084 on the national average, diesel at €2.289, more than 20 cents apart². The two are moving in opposite directions. E10 fell 2.6 cents in a week while diesel rose 3.4 cents, with Brent at about $114 a barrel². The automobile club blames tight international diesel markets and the seasonal demand for heating oil, and reads the petrol move as a sign that there had been room for cuts².

The plate. Food and non-alcoholic drinks cost 0.4% more than a year ago¹. In March 2025 that line was rising at 3.5%¹. For a household that spends more at the checkout than at the pump, this is the quiet good news of the year, and it gets few headlines because nothing happened. A supermarket that keeps its prices is not a story. It is a supply chain, a wholesale contract and a lot of people doing their jobs.

The boiler. Electricity, gas and other household fuels cost 1.9% less in Germany than a year ago¹. That line has been below zero in every month since January 2025¹. Across the euro area as a whole, the same line rose 9.4%¹. Desk arithmetic: that is a gap of 11.3 percentage points between what a German household and the average euro-area household pay for heat and light, in the same month, with the same war on the news. Eurostat’s table does not say why; it only records the difference. The point for you is simpler: a figure from Brussels or Frankfurt about “energy prices” may not describe your meter at all.

What the committee sees. The ECB has to set one rate for all of it. Newsquawk’s preview expects the deposit rate to stay at 2.50% today, after September’s quarter-point rise, with energy the main argument for doing more and France’s bond market the main argument for caution³. It notes that euro-area energy inflation reached 18.9% in September and added 1.71 points to the headline rate of 3.8%³. Desk arithmetic: take energy’s 1.71 points away and about 2.1 points of the 3.8% remain. It also recalls President Christine Lagarde’s recent observation that there has not yet been a material response in wages³. That is the sentence to hold on to. Fuel at 36.8% is a shock. A shock becomes inflation in the full sense only when it moves into payslips, rents and service prices, and does not come back out.

The dull defence. Nothing in this ledger is comfortable for a commuter who drives a diesel van. But the lines that are behaving matter as much as the one that is not. The checkout and the meter have not followed the pump, so far, and a shock that stays in one line is a shock a household can plan around. The central bank, whatever it decides at 14:15 CET, will announce it on a timetable everyone knew, explain it at 14:45 CET, and publish the reasons. That machinery is not exciting. It is the reason a jump at the pump does not have to become a jump in everything.

What you can do. Read your own three lines rather than the headline. If the car is the problem, the ADAC’s standing advice is to fill up shortly before noon, when prices are lowest in the daily cycle, and to compare stations; the price jumps at 12:00 and then eases back slowly². If heating is your worry, look at your actual tariff and its end date before reading another national average. And tomorrow, when Destatis publishes its first October figures⁴, look past the first digit to the lines underneath. Nothing here is investment advice.
