The largest bank in France saw a 28 per cent net profit rise in the fourth quarter, reaching â¬1.72 billion (Â£2.26 billion) from â¬1.34 billion.
Revenues also rose significantly, from â¬1.34 billion a year earlier to their current level of â¬1.72 billion.
An increase in its investments in larger-growing markets was a significant factor in the bank's performance. Rome-based Banca Nazionale del Lavoro was one such acquisition, which gained it an extra three million retail customers and contributed â¬177 million to pre-tax profit.
There are concerns ahead, though, in the European banking sector - as Yves Marcais, a strategist at Global Equities in Paris, told Bloomberg.
He said: "European banks posted great results for 2006 but the question now is, how can such good results be sustainable this year? This concern is what is pushing shares down today."
