Madrid, Spain – The Ibex 35, Spain's leading stock market index, concluded Tuesday's trading session with a modest gain of 0.29%, settling at 11,468.5 points. This comes amid a week of generally subdued trading activity due to the Christmas holiday season.

Monday's news of Spain's economy expanding by 0.8% in the third quarter, matching the previous quarter's growth, provided a positive backdrop. This growth was primarily driven by increased government spending, which surged by 2.5% on a quarterly basis – the highest rate since records began in 1995.

In the corporate arena, Grifols successfully completed a private placement of senior secured bonds worth €1.3 billion, maturing in May 2030 and carrying a 7.125% annual coupon. Additionally, Iberdrola finalized the acquisition of 100% of its subsidiary, Avangrid, after securing regulatory approval from New York.

While the remainder of the week is expected to see limited trading due to the Christmas holidays, the overall sentiment in European markets remains positive. London's FTSE 100 rose by 0.42%, and Paris's CAC 40 increased by 0.14%.

In the commodities market, the price of Brent crude oil climbed 0.75% to $72.83 per barrel at the close of the European session. Similarly, West Texas Intermediate (WTI) crude rose by 0.92% to $69.88 per barrel.
