ECB Raises Rates to 2.50% as Iran War Fuels Euro Zone Inflation

The European Central Bank raised its deposit facility rate by 25 basis points to 2.50% on Thursday, the second increase in what is on track to become its shortest hiking campaign since 2011.

What happened

The Governing Council's decision was unanimous. Alongside the deposit rate, the main refinancing rate rose to 2.65%. All 65 economists in a Reuters poll conducted between August 31 and September 3 had forecast the move.

The trigger is inflation. Euro area headline inflation climbed to 3.3% in August, up from 2.9% in July and the highest reading since September 2024. Energy inflation accelerated to 14.3% from 10.3%, driven by disruption tied to the war between Iran and Israel and renewed volatility around the Strait of Hormuz.

At her press conference, ECB President Christine Lagarde confirmed the bank's new staff projections:

• Headline inflation: 3.0% in 2026, 2.3% in 2027, 2.0% in 2028
• Core inflation (excluding energy and food): 2.5% in both 2026 and 2027, easing to 2.2% in 2028

Lagarde kept the statement's language tied to meeting-by-meeting data dependence and gave no guidance on October. She also pushed back directly on market pricing that implied roughly 80 additional basis points of hikes through mid-2027, without ruling them out.

Why it matters

The deposit rate now sits at or above the upper end of the ECB's informal neutral range of 1.5% to 2.5%. That is a meaningful shift for anyone holding European fixed income, equities, or cash in euros.

German 10-year Bund yields fell after the announcement as investors priced out some of the additional tightening Lagarde had rejected. The euro weakened against the dollar. Both moves reflect a market recalibrating how much further this cycle has to run, not whether the ECB is done raising rates yet.

For portfolios with European exposure, the practical effect runs through borrowing costs, bond valuations, and the relative appeal of cash versus risk assets. A rate move like this touches every asset class at once. Portfolio trackers that consolidate holdings across brokers and banks make it easier to see the full effect in one place.

What to watch next

This is the ECB's shortest hiking campaign since 2011, when it raised rates twice in quick succession in response to an oil price shock. That precedent did not last: the ECB cut rates again within months once the shock faded.

The next Governing Council meeting will show whether September marks the top of this cycle or the start of a longer one. Three factors will decide it: whether Iran-linked energy disruption persists, whether headline inflation actually falls back toward the 3.0% projection, and how the ECB weighs a slowing euro area economy against still-elevated prices.

Riksbanken, by contrast, held its policy rate steady at 1.75% on September 7, underscoring how differently Nordic and euro area central banks are reading the current inflation picture.
