The European Central Bank raised all three policy rates by 25 basis points on 10 September, responding to energy-driven inflation from the Middle East conflict. From 16 September, the deposit rate will be 2.50%, the main refinancing rate 2.65% and the marginal lending rate 2.90%.
The message for investors is more concrete than the original headline suggested: policy has already tightened, the ECB expects inflation to remain above its 2% target for an extended period, and the path beyond this meeting remains data-dependent. That combination raises discount rates while leaving growth and earnings exposed to the same energy shock that prompted the hike.
What the ECB now forecasts
The September baseline projects headline HICP inflation averaging 3.0% in 2026, 2.5% in 2027 and 2.1% in 2028. Inflation excluding energy and food is forecast at 2.5%, 2.6% and 2.3%, respectively. The ECB expects headline inflation to peak at 3.6% in the fourth quarter of 2026 as higher crude, refined-product, gas and electricity costs reach consumers.
| ECB baseline | 2026 | 2027 | 2028 |
|---|---|---|---|
| Headline HICP | 3.0% | 2.5% | 2.1% |
| HICP excluding energy and food | 2.5% | 2.6% | 2.3% |
| Real GDP growth | 0.9% | 1.4% | 1.5% |
Compared with June, the 2026 inflation forecast is unchanged, while 2027 and 2028 were revised higher. The baseline assumes that the energy shock gradually fades and that indirect and second-round effects remain contained. That is an assumption, not a certainty: the ECB’s alternative scenarios span materially weaker growth and higher inflation if energy disruption lasts longer or feeds more forcefully into wages and non-energy prices.
Why the rate hike matters across assets
Sovereign bonds: a higher policy floor and slower disinflation can keep front-end euro rates elevated. Longer-dated Bunds and peripheral debt face a two-sided risk: inflation can push yields higher, while a sharper growth slowdown can eventually revive duration demand. Sovereign spreads will also reflect fiscal credibility and the ECB’s transmission tools.
Euro: tighter ECB policy can support the currency when rate differentials move in Europe’s favour, but an adverse energy shock worsens the trade balance and growth outlook. EUR performance will therefore depend as much on relative U.S. and UK policy as on the ECB itself.
Equities and credit: higher discount rates are a headwind for long-duration valuations and leveraged balance sheets. Banks may benefit from asset repricing, but only while deposit costs and credit losses remain controlled. Airlines, chemicals, transport and other energy-intensive businesses face direct margin pressure; utilities and industrials may also carry larger working-capital needs.
Bullish and bearish interpretations
The more constructive reading is that the euro-area economy has been resilient enough for the ECB to tighten: staff lifted its baseline growth forecasts for 2026 and 2027, and the labour market remains supportive. If energy prices normalise quickly, inflation could fall without a deep contraction, allowing real incomes and domestic demand to recover.
The bearish reading is a stagflationary one. If energy prices remain high, companies may pass costs through, wage demands may adjust and the ECB may need to keep policy restrictive even as activity weakens. The central bank’s severe scenario illustrates that tail risk; investors should not treat the baseline as a narrow confidence interval.
What investors should monitor
- Spot and forward prices for oil, gas, electricity and refined products.
- Monthly HICP components, especially services and non-energy goods.
- Negotiated wages, compensation per employee and inflation expectations.
- Bank lending surveys, corporate defaults and peripheral sovereign spreads.
- ECB language on indirect and second-round effects; the Governing Council has not pre-committed to a rate path.
