KEY POINTS
- Markets price a 99% probability the ECB will raise its deposit rate by 25 basis points to 2.25% on June 11, marking the first hike since September 2023.
- Eurozone headline inflation hit 3% in April, a full percentage point above the ECB's target, as the Iran-linked oil shock passes through to European energy costs.
- A second 25bp hike is expected in September, and ECB President Lagarde's tone on Wednesday will signal whether the tightening cycle extends further.
The European Central Bank will almost certainly raise interest rates on Thursday for the first time since September 2023, completing one of the fastest policy reversals in the institution's history. Markets are pricing a 99% probability of a 25 basis point hike to 2.25% on the deposit facility rate, a move that would formally end the easing cycle that brought rates down from 4% to 2% between June 2024 and January 2026.
Six months ago, the ECB was debating how quickly to cut rates toward 1.50%. Now it is debating how many times it needs to hike. The pivot is almost entirely the result of one event: the Strait of Hormuz closure in February, which sent oil prices surging and dragged eurozone inflation from a manageable 2.2% in January to 3% in April.
Why Europe Gets Hit Harder
The eurozone's energy vulnerability is structural. Europe imports roughly 90% of its oil and 60% of its natural gas, compared to the United States, which is a net energy exporter. When oil spikes from $70 to $95 per barrel, the pass-through to European consumer prices is faster and larger.
The ECB's own staff projections revised headline inflation upward to 2.6% for 2026 at the March meeting, but that estimate is already stale. April's 3% reading blew through it, and May is expected to come in around 3.2% when Eurostat publishes the flash estimate later this month.
Energy is the headline driver, but core inflation is proving stubborn as well. Services inflation in the eurozone remained at 3.9% in April, reflecting tight labor markets and wage growth that has not yet responded to the economic slowdown. The ECB's own wage tracker shows negotiated pay increases running at 4.1% year-over-year, the fastest pace since the monetary union began.
Lagarde's Balancing Act
ECB President Christine Lagarde telegraphed this move clearly. At the April meeting, she said the decision to hold rates was unanimous but revealed that a hike had been discussed "at length". She described the June meeting as "the right time" for a reassessment. The market took the cue.
The challenge for Lagarde on Thursday is managing expectations beyond June. Economists surveyed by Bloomberg expect a second 25bp hike in September, which would take the deposit rate to 2.50%. But there is a growing minority view that the ECB may need to move more aggressively if oil prices remain elevated and the Hormuz strait stays effectively closed.
Germany's economy, the eurozone's largest, contracted 0.1% in Q1 and is flirting with a technical recession. Italy's industrial production fell 2.3% in April. Hiking rates into economic weakness is the definition of a policy bind, and Lagarde's press conference language will be parsed for any acknowledgment that the growth-inflation tradeoff is worsening.
What Traders Should Watch
The rate decision itself is priced in and should not move markets. What matters is the updated staff economic projections and Lagarde's guidance language. If the ECB raises its 2026 inflation forecast above 3% and keeps the door open for a third hike in December, the euro could strengthen toward 1.12 against the dollar, putting additional pressure on European exporters and potentially dragging the Stoxx 600 lower.
For U.S.-based traders, the ECB decision matters because it reinforces a global tightening impulse. If both the ECB and the Fed are moving toward hikes — or at minimum, away from cuts — the interest rate environment for risk assets deteriorates meaningfully. The correlation between European and U.S. sovereign yields has been running above 0.80 since March, meaning ECB hawkishness tends to pull Treasury yields higher as well.
Thursday's ECB decision at 8:15 a.m. ET, followed by Lagarde's press conference at 8:45 a.m., sets the stage for the following week's Fed meeting. Together, these two central bank events will define the rate landscape for the summer.
