Consumer prices jumped by 5.6 percent, up from a 5.4 percent increase in October, according to preliminary figures from national statistics institute.
That is its fastest pace since September 1992, when the rate was 5.8 percent.
The surge in inflation in the eurozone’s fourth-largest economy was due largely to a spike in food prices, followed by higher gas prices, the statistics office said.
Electricity costs, however, declined slightly after a month-long acceleration, it added.
As in other European Union nations, inflation in Spain has risen since the start of the year after consumer prices declined during most of 2020 due to the economic impact of pandemic lockdowns.
In October, eurozone inflation reached 4.1 percent, well above the European Central Bank’s target of two percent and equal to a high set in July 2008.
But the bank believes eurozone inflation will peak in November and is set to gradually slow next year as supply bottlenecks and the energy crunch ease, board member Isabel Schnabel said earlier this month.
Investors worry central banks will withdraw their stimulus measures sooner than expected to tame inflation.
