The Spanish stock index Ibex-35 opened Tuesday recovering the level of 9,500 points, lost the day before, in a context of nervousness in view of the imminent news on the central banks' fight against inflation.

During the morning, the final Eurozone price index for August will be released (0900 GMT), but the highlight of the day will be the meeting of the Federal Open Market Committee (FOMC) of the U.S. Federal Reserve (Fed).

"Part of the market expects no change in the same, but the pickup in inflation could change the minds of FOMC members and make a 25bp hike to the 5.50-5.75% bracket," said Diego Morin, analyst at IG.

As the debate continues over when the ceiling on interest rate hikes by major central banks will be reached, concerns are growing over rising oil and energy prices in general, which could reignite inflation with the northern winter in sight.

On Tuesday, Brent crude was up 0.54% at $94.94 per barrel, and some analysts see it as likely to rise above $100.

Against this backdrop, European stock markets were barely impacted by the good news from Chinese real estate, where two distressed companies reached agreements to restructure their debt.

At 0816 GMT on Tuesday, Spain's selective Ibex-35 stock market index was up 50.70 points, or 0.53%, to 9,532.80 points, while the FTSE Eurofirst 300 index of large European stocks was up 0.20%.

In the banking sector, Santander rose 0.29%, BBVA gained 0.45%, Caixabank advanced 0.25%, Sabadell gained 0.73%, Bankinter gained 0.34%, and Unicaja Banco rose 1.20%.

Among the large non-financial stocks, Telefónica gained 0.88%, Inditex advanced 0.48%, Iberdrola gained 0.77%, Cellnex gained 0.14%, and the oil company Repsol rose 0.81%.

The stock with the greatest variation was Fluidra, which lost 2.4%, after having risen more than 32% so far this year.
