The European Central Bank kept borrowing costs unchanged Thursday but opened the door to further tightening after oil prices surged past $97 a barrel.
The ECB held its deposit rate at 2.25% on Thursday, pausing after a year of cuts, but signaled it could resume hiking as Brent crude's surge to $97.73 threatens to reignite inflation across the eurozone.
"The outlook for inflation has become more uncertain due to the sharp increase in energy costs, and we stand ready to adjust all instruments if needed," ECB President Christine Lagarde said at the press conference in Frankfurt.
The decision to hold was unanimous, according to a statement. The main refinancing rate stays at 2.40% and the marginal lending facility at 2.65%. Eurozone inflation fell to 2.8% in June from 3.2% in May, but the 12th consecutive night of US strikes on Iran and Houthi threats to blockade Saudi ports have pushed Brent crude up 4.3% this week alone, threatening to reverse the disinflation trend.
The shift in tone puts the ECB on a collision course with markets that had priced in further easing. Money markets now see a 45% probability of a quarter-point hike at the September meeting, up from 12% a month ago. If oil holds above $95, the ECB may have little choice but to act, potentially pushing eurozone government bond yields higher and strengthening the euro.
Oil's Shadow Over the Inflation Outlook
The last time the ECB confronted a similar oil-driven inflation scare was in mid-2022, when Brent averaged $110 a barrel and the central bank delivered a 50-basis-point hike in July of that year. That tightening cycle ultimately lifted the deposit rate to a record 4.0% before the ECB began cutting in June 2024. Today's situation differs in magnitude — oil is roughly $12 below that 2022 average — but the direction of travel is identical, and the transmission to consumer prices could be faster given already-elevated energy costs in the eurozone.
Brent crude has gained 18% since the start of June, driven by the escalating conflict between the US and Iran and Houthi threats to blockade Saudi ports in the Red Sea. The risk of a sustained supply disruption has pushed the oil complex into backwardation, with front-month contracts trading at a premium to deferred deliveries — a classic sign of physical tightness. For the ECB, each $10 sustained increase in oil adds roughly 0.4 percentage points to eurozone headline inflation within six months, according to European Commission models.
Cross-Asset Fallout
The hawkish hold reverberated across European markets. The euro rose 0.2% to $1.1426, its highest in three weeks against the dollar. German 10-year bund yields climbed 6 basis points to 2.58%, while Italian BTPs underperformed, pushing the spread over bunds to 148 basis points. The Stoxx Europe 600 fell 0.4%, led lower by rate-sensitive real estate and utility stocks, while energy shares gained 1.8% as BP and Shell advanced on higher oil prices.
The dollar index edged down 0.1% to 104.2, reflecting the euro's strength, though the greenback hit a three-week high earlier in the session before the ECB decision. Gold slipped to $4,094.64 an ounce, down 1.5% on the day, as higher real yields reduced the appeal of non-yielding assets.
What Comes Next
The ECB's next scheduled meeting is Sept. 10, by which time the council will have two more months of inflation data and a clearer picture of oil's trajectory. Lagarde emphasized that the bank is "data-dependent" and not on a pre-set path, but the shift in language from June's communique — which described inflation as "on track to return to target" — to Thursday's more cautious tone suggests the bar for further easing has risen substantially.
For investors, the calculus has inverted. Three weeks ago, the debate was about the pace of cuts. Now it is about whether the next move is a hike. If Brent crude breaches $100 — a level some traders say is plausible if the Hormuz Strait disruption persists — the ECB may need to act before September, potentially at an unscheduled meeting. That scenario would mark the first time a major central bank has reversed an easing cycle since the ECB itself did so in 2011, when it raised rates twice before the eurozone debt crisis forced it to cut again.
