FRANKFURT, June 15 — The European Central Bank hiked interest rates to a 22-year high today and said another increase in July was "very likely", as it pushed ahead with its fight against inflation despite a darkening eurozone economy.

The ECB's governing council increased rates by a further 25 basis points, taking the closely-watched deposit rate to 3.50 per cent — its highest level since 2001.

"Inflation has been coming down but is projected to remain too high for too long," ECB president Christine Lagarde said.

The move comes a day after the US Federal Reserve held off from raising rates after 10 straight increases.

"We're not thinking about pausing," Lagarde said, adding that the ECB still has "ground to cover" on rates after the Frankfurt institution lifted its inflation outlook for 2023-2025 in fresh forecasts today.

"Barring a material change to our baseline, it is very likely the case that we will continue to increase rates in July," she told reporters.

The ECB has lifted borrowing costs at the fastest rate ever to combat red-hot inflation after Russia's war in Ukraine sent food and energy prices soaring, raising its key rates by 4.00 percentage points since July.

Eurozone inflation slowed to 6.1 per cent in May year-on-year, down from a peak of 10.6 per cent in October, mainly thanks to rapidly falling energy costs.

The ECB said its inflation-busting efforts were "gradually having an impact", with loan demand slowing sharply as higher borrowing costs take their toll on eurozone households and firms.

But inflation remains three times above the ECB's target while core inflation — which strips out volatile food and energy prices — eased only slightly to 5.3 per cent in May, after 5.6 per cent in April.

Lagarde reiterated today that the ECB will "follow a data-dependent approach" as it charts the way forward.

"The ECB simply cannot afford to be wrong on inflation," said ING bank economist Carsten Brzeski.

"The bank wants and has to be sure that it has slayed the inflation dragon before considering a policy change."

'Not satisfactory'

Like all central banks, the ECB has to walk a fine line in raising interest rates sufficiently to dampen demand and contain inflation, without provoking a sharp economic slowdown in the process.

But the eurozone economy has proved less resilient than initially thought.

Revised data last week showed that the economy in the 20-nation currency union shrank by 0.1 per cent for two straight quarters at the end of 2022 and the start of 2023, meeting the technical definition of a recession.

While still mild, the surprise winter slump has cast doubt on more optimistic economic forecasts for 2023.

In updated forecasts, the ECB now sees the eurozone economy growing by 0.9 per cent in 2023 — down from 1.0 per cent previously.

Lagarde said the economy would "strengthen in the course of the year" as inflation slows, supply chains ease and the service sector remains resilient.

But she stressed that the outlook remained "highly uncertain", citing Russia's war in Ukraine and potentially weak global growth among the risk factors.

'We will get there'

Thursday's updated projections also showed inflation reaching 5.4 per cent in 2023, 3.0 per cent in 2024 and 2.2 per cent in 2025 — a 0.1-percentage-point increase for each year from its last forecasts in March.

With the ECB's two-per cent target still out of reach by 2025, Lagarde called the outlook "not satisfactory".

Wage pressures were becoming an "increasingly important source" of inflation, she said, as workers — boosted by record-low eurozone unemployment — push for pay rises to help compensate for the higher cost of living.

She also expressed concern about high corporate profits, urging companies and employees to avoid a "tit-for-tat" where both sides sought full compensation for inflation — potentially creating an unwanted spiral of price rises.

The ECB was watching the discussions and developments between the different parties in the labour market closely, Lagarde said.

The central bank "will take all necessary measures to return inflation to two per cent. That they can count on," she said.

"And we are confident that we will get there." — AFP
