ECB key rate at 2.50 per cent (September 2026): what it means for merchants
ECB rate decision of 10 September 2026: all three key rates rise by 25 basis points, with the deposit facility at 2.50 per cent from 16 September. The projections see inflation at 3.0 per cent in 2026, 2.5 per cent in 2027 and 2.1 per cent in 2028. For merchants that is two calculations: more expensive financing and an average basket size that keeps falling in real terms.
What happened
On 10 September 2026 the ECB Governing Council decided to raise the three key interest rates by 25 basis points each. With effect from 16 September 2026 the deposit facility stands at 2.50 per cent, the main refinancing rate at 2.65 per cent and the marginal lending facility at 2.90 per cent. The press conference with President Christine Lagarde and Vice-President Boris Vujčić was held in Berlin. The new staff projections were published at the same time: headline inflation is seen averaging 3.0 per cent in 2026, 2.5 per cent in 2027 and 2.1 per cent in 2028, and the rate excluding energy and food at 2.5, 2.6 and 2.3 per cent. For economic growth the projection names 0.9 per cent this year, 1.4 per cent in 2027 and 1.5 per cent in 2028. Compared with the June round, the inflation figures for 2027 and 2028 and the growth figures for 2026 and 2027 have been revised upwards. Only in 2028 is expected inflation back close to the two per cent target.
Who it affects
Every business financing a till, terminal, refrigeration or shopfitting over the coming months — by leasing, hire purchase or overdraft. Also everyone whose business depends on the average basket size: hospitality, bakeries, to-go, kiosks, specialist retailers with a narrow range. And sales organisations planning 2027 budgets, which have to reckon with a lower willingness to invest among their customers.
What it means
I do not judge monetary policy, I translate it into till figures. And there two sentences from the projection sit side by side that have to be read together: prices are rising more strongly through to 2028 than previously expected, and growth stays below one per cent this year. For retail that does not mean recession, it means something more grinding — turnover that holds up in nominal terms and volumes that do not. Exactly that pattern was already visible in this week’s EHI survey on in-store hospitality: record turnover, carried by prices and the snack business, not by larger purchases.
On the financing side the move is tangible. Anyone financing a terminal fleet or a till system over 36 or 48 months is now negotiating in an environment where money has become more expensive again — and in which many leasing offers quietly write the rate increase into the instalment instead of disclosing it. My recommendation to every merchant with an offer on the table this quarter: have the total sum over the term quoted to you, not the monthly instalment. With an interest differential of two to three per cent, the difference between rental, hire purchase and purchase quickly becomes a four-figure amount per device, and it disappears into the instalment just as fast as it becomes visible in the total price. That is not a comment on interest rates, that is purchasing.
What to do now
- Review all current financing arrangements for till, terminal and shop technology for remaining term and effective annual interest rate. Contracts with variable rates first.
- For every new offer, have the total cost over the full term disclosed and compare rental, hire purchase and purchase in the same table.
- Look at your own average basket size over the past twelve months in real terms, that is, adjusted for price increases. Only then does it become visible whether the business is growing or merely getting more expensive.
