The Spanish stock index Ibex-35 opened Tuesday's session with slight losses after touching 10,000 points at Monday's close, at a time when investors await the release of a key U.S. inflation report that could help shape the Federal Reserve's rate outlook.

The recent run of favorable U.S. economic data, particularly this month's jobs report, has raised expectations that U.S. interest rates will remain on the upside for longer.

However, Renta 4 analysts caution "that the latest headline CPI showed some uptick against the forecast and core (inflation) remains almost double the 2% target, against a backdrop of solid economic growth and labor market."

Markets currently expect the Fed to cut interest rates by 110 basis points this year starting in May, down from 160 basis points at the end of last year.

In addition to the US inflation data, due at 1330 GMT, markets will be watching the February ZEW survey in Germany (1000 GMT).

Chinese financial markets are closed for the Lunar New Year holiday and will resume trading on Monday, February 19, while Hong Kong markets will resume trading on February 14.

At 0804 GMT on Tuesday, Spain's selective Ibex-35 stock market index was down 22.80 points, or 0.23%, to 9,961.90 points, while the FTSE Eurofirst 300 index of large European stocks was down 0.14%.

In the banking sector, Santander lost 0.31%, BBVA fell 0.02%, Caixabank ceded 0.23%, Sabadell gained 0.04%, Bankinter gained 0.31%, and Unicaja Banco lost 0.31%.

Among the large non-financial stocks, Telefónica fell 0.17%, Inditex dropped 0.51%, Iberdrola gained 0.28%, Cellnex fell 1.49%, and the oil company Repsol rose 0.50%.
