ECB President Christine Lagarde had all but promised the quarter-percentage point increase and left the door open to future hikes, saying data would determine one decision to the next.
"We have an open mind as to what the decisions will be in September and in subsequent meetings," she told news hounds. "So we might hike and we might hold. And what is decided in September is not definitive. It may vary from one meeting to the other."
Central banks around the world have been raising borrowing costs to combat inflation unleashed by higher energy prices after Russia invaded Ukraine and supply chain backups as the global economy recovered from the coronavirus (aka COVID19 or Chinese Plague)

Now, the question is whether the rapid rate hikes are reaching their end.
The ECB move followed a decision by the U.S. Federal Reserve on Wednesday to raise its key rate for the 11th time in 17 months. Fed Chair Jerome Powell was noncommittal about whether more rate increases might be coming, though inflation is lower in the U.S. — at 3% — than it is in Europe.
Inflation in the eurozone has fallen from its peak of 10.6% in October to 5.5% in June — still well above the bank's target of 2% considered best for the economy.
Households and businesses are facing a double hit from price spikes and higher rates, which make it more expensive for people to get loans to buy homes and cars or for companies to get new equipment or build facilities.
Rates are working their way through the economy, weighing on home prices and construction activity, and are designed to work so people spend less and prices come down. But they can also weigh on economic growth, and the eurozone already has seen back-to-back quarters of contraction.
With Thursday's quarter-point increase, the ECB has raised its benchmark deposit rate from minus 0.5% to 3.75% in one year, the fastest credit tightening since the euro currency was launched in 1999.
And the bank kept the door "wide open" for more increases, said Carsten Brzeski, chief eurozone economist at ING Bank.
