The eurozone's central bank announces its biggest interest rates increase as inflation sits at record levels and the 19 countries that use the euro head for a recession.
The European Central Bank (ECB) has hiked its key interest rates by an unprecedented 75 basis points, signalling that further rises are likely.
On Thursday afternoon, the bank - which makes monetary policy for the eurozone and the European Union - lifted the deposit rate from zero to 0.75% and the main refinancing rate was lifted to 1.25%, the highest level since 2011.
It comes as inflation is at a half-century high, and as the bloc heads for a likely winter recession.
In a statement, the ECB said: "Over the next several meetings the Governing Council expects to raise interest rates further to dampen demand and guard against the risk of a persistent upward shift in inflation expectations."
The bank has revised its economic forecast, projecting inflation averaging 8.1% this year, 5.5% in 2023, and 2.3% in 2024.
Inflation was initially driven by energy prices - exacerbated by Russia's invasion of Ukraine - but it is also being fuelled by the drought seen in recent months.
The ECB said: "Price pressures have continued to strengthen and broaden across the economy and inflation may rise further in the near term.
"This major step frontloads the transition from the prevailing highly accommodative level of policy rates towards levels that will ensure the timely return of inflation to the ECB's 2% medium-term target."
The ECB has forecast GDP growth at 3.1% this year - up from the 2.8% projection it made in June, but it cut its 2023 forecast from 2.1% to 0.9%.
'Euro slide putting upward pressure on inflation'
Rob Clarry, investment strategist at Evelyn Partners, said: "While eurozone inflation has largely been driven by supply side challenges rather than excessive demand, the ECB has acted firmly as it looks to avoid expectations of higher inflation from becoming entrenched.
"Another crucial reason is to try and halt the euro's slide against the US dollar given that this has put further upward pressure on inflation.
"Fundamentally, it appears that the ECB is taking a similar stance to the Bank of England and the Federal Reserve: tackling inflation at the expense of economic growth.
'Positives we can draw on'
"While the economic outlook appears challenging there are some positives we can draw on.
"First, the eurozone has made good progress in replenishing its gas stocks ahead of winter; whether this will be enough depends on ongoing flows and the winter weather.
"Second, it looks like there's a consensus emerging around the bloc that governments need to support households by subsidising energy bills.
"Indeed, this week we saw Germany (€65bn), Portugal (€2.4bn) and the Netherlands (€16bn) announce support packages.
"This should prop up consumer spending as the eurozone looks to avoid a prolonged economic contraction."
In currency trading, the euro initially went above parity against the dollar, but has since weakened. The pound hit a fresh two-and-a-half month low of 86.95 pence per euro early in the day before recovering a little.
