Jul 20 (Reuters) - The Spanish stock index Ibex-35 opened Thursday's session higher, with investors looking ahead to the publication of corporate results in the United States and Europe and awaiting the decisions of central banks next week.

Following Wednesday's release of a final eurozone inflation figure of 5.5%, markets will need "new data to confirm whether, as several ECB members claim, core inflation has peaked or not," analysts at Renta 4 said in their daily analysis note.

Before markets opened, the German statistics office reported that the country's producer price index fell 0.3% in June.

At 0711 GMT on Thursday, Spain's selective Ibex-35 stock market index was up 40.80 points, or 0.43%, to 9,492.60 points, while the FTSE Eurofirst 300 index of large European stocks was down 0.16%.

Bankinter fell to the bottom of the index with a drop of 2.48% after publishing its second-quarter results.

In the rest of the banking sector, Santander rose 0.46%, BBVA gained 0.90%, Caixabank advanced 0.71%, Sabadell gained 0.22%, and Unicaja Banco rose 0.60%.
