Delfin Sarl, the investment arm of the Del Vecchio family, has firmly denied reports that it's negotiating a sale of its 17.5% stake in Banca Monte dei Paschi di Siena with UniCredit. The denial comes amid ongoing speculation about the future ownership of Italy's oldest bank, a perennial subject of market chatter and restructuring efforts.

This stake represents a significant holding in a lender that has long been a focus of Italian banking sector stability. UniCredit's interest, if real, would signal a potential consolidation move in a crowded domestic market. For the Del Vecchio family, maintaining control of Paschi has been a strategic investment following earlier state-backed rescue efforts.

The denial likely aims to quell immediate market rumors, but the underlying question of Paschi's ownership remains open. Investors will watch for any shifts in UniCredit's strategy or alternative suitors for the stake. The saga underscores the complex web of ownership that continues to shape Italy's banking landscape, with Delfin's position remaining a key variable.
