The rate accelerated from October's 5.4% to reach its highest level since September 1992's 5.8%. Inflation has been rising across the euro zone in recent months, with Spain particularly hard hit.

Rising food costs were the main driver, followed by vehicle fuels and lubricants. However, a months-long acceleration in electricity costs reversed in November, according to the INE.

On a EU-harmonised basis, Spanish inflation also rose by 5.6% in November, up from 5.4% in October, the INE data showed.

Core inflation, which strips out food and energy prices and is used by central banks as a monetary policy determinant, rose to 1.7%, its highest since July 2013.

The European Central Bank believes euro zone inflation will have peaked in November and is set to gradually slow next year as supply bottlenecks and the energy crunch ease, according to board member Isabel Schnabel.
