ECB rate hike: what the 10 September 2026 decision changes for businesses

What the Governing Council decided

On 10 September 2026, the ECB announced a 25-basis-point increase across its three key interest rates, bringing:

• the deposit facility rate to 2.50%

• the main refinancing operations (MRO) rate to 2.65%

• the marginal lending facility rate to 2.90%

These new rates take effect on 16 September 2026. This marks the ECB's second rate hike since the onset of the conflict in the Middle East, following an initial increase decided on 11 June 2026. The next Governing Council meeting is scheduled for 29 October 2026, and futures markets are already pricing in the possibility of a third rate rise before the end of the year.

Why the ECB is shifting course: the energy shock linked to the war in the Middle East

Since 2024, the ECB had embarked on a cycle of rate cuts to support a sluggish European economy. The conflict in the Middle East has reshuffled the cards by triggering a sustained rise in energy prices, with direct repercussions on inflation across the euro area.

In its new projections published on 10 September, the institution now forecasts average inflation of 3.0% in 2026, compared to a 2% target, before a gradual return towards the target in 2028. Core inflation (excluding energy and food) has also been revised upwards to an average of 2.5% over 2026 and 2027. The ECB justifies its decision by the need to prevent this energy shock from spreading more broadly throughout the economy via second-round effects on wages and prices.

The consequences for corporate and household lending

A hike in key interest rates is never immediately or mechanically passed on to commercial lending rates. Existing fixed-rate loans remain unchanged. However, new financing—credit lines, investment loans, mortgages—tends to become progressively more expensive as banks adjust their rate schedules.

For an SME financing supplier purchases or capital expenditure through credit, this translates into slightly higher borrowing costs in the months ahead, providing an additional incentive to weigh financing decisions more carefully against cash management.

A stronger, yet more volatile euro: the impact on international payments

A rate hike mechanically tends to support the currency in question by making euro-denominated assets more attractive to international investors. Yet the current environment is far from a standard monetary tightening cycle: it is driven by a geopolitical shock whose scale and duration remain uncertain.

Consequently, foreign exchange markets are factoring in both the prospect of further rate increases and the risk of escalation in the conflict—two countervailing forces that can pull in opposite directions from one week to the next. For a company invoicing or paying suppliers in US dollars, pounds, or other currencies, this volatility significantly complicates establishing reliable profit margins on contracts spanning several months.

It is precisely during such periods of shifting interest rates and jittery currencies that the lack of an FX hedging strategy proves most costly—a swing of just a few pence or cents on an exchange rate can be enough to wipe out an entire commercial margin. Solutions such as forward contracts allow businesses to lock in today's rate for a future transaction, shielding them from market swings. This is the type of support that OSolto, an international payments specialist registered with ORIAS (no. 26004337), provides to French SMEs operating internationally, in partnership with technology providers like Ebury and CurrencyCloud.

Key takeaways

The ECB has resumed its cycle of rate hikes for the second time since June, driven by the energy shock stemming from the Middle East conflict. While the impact on borrowing costs remains gradual, the volatility accompanying these decisions represents, in the short term, the most immediate risk for businesses exposed to foreign currencies.

FAQ

What are the ECB's current key interest rates? As of 16 September 2026, the deposit facility rate is at 2.50%, the main refinancing operations (MRO) rate is at 2.65%, and the marginal lending facility rate is at 2.90%.

Why is the ECB raising rates in 2026 after lowering them? Surging energy prices linked to the conflict in the Middle East have driven up the ECB's inflation forecasts, prompting the central bank to tighten monetary policy to prevent this shock from spilling over into the broader economy.

Does an ECB rate hike automatically strengthen the euro? Not necessarily. In theory, it supports the currency, but amidst geopolitical tensions, other factors can counteract this effect and heighten short-term volatility.

How can an SME protect itself against currency volatility? By implementing an FX hedging strategy (such as forward contracts or planned spot transactions) with an authorised payment provider, rather than being subject to market fluctuations at the time of each transaction.
