A high-stakes bidding war has broken out for Banca Monte dei Paschi di Siena (MPS), recognized as the world’s oldest bank, after two rival Italian lenders stepped forward with competing proposals. Founded in 1472 in Siena by the Republic of Siena to extend credit to impoverished citizens, the Tuscan institution has grown over more than five centuries into a pillar of Italy’s financial system.
Rival Bids Erupt for Banca Monte dei Paschi di Siena
The race for control of the historic lender intensified within a 24-hour window. On Monday, Italy’s largest bank, Intesa Sanpaolo, launched a surprise, unsolicited bid valued at 30.6 billion euros (approximately $35.3 billion to $36 billion depending on the valuation figures cited by CNBC and Cbsnews). Intesa’s proposal represented a 12.5% premium over MPS’s closing share price on Friday, with the target bank valued at 27.4 billion euros.
Intesa’s move gatecrashed an approach made just one day earlier by Banco BPM, Italy’s third-largest bank by assets (noted as the fourth-largest lender by Thebanker). Banco BPM announced that its board had unanimously approved expressing interest in discussing a merger of equals
. While Banco BPM did not disclose specific financial terms, it stated that the combined group would possess a market capitalization of around 50 billion euros ($58 billion) and form Italy’s second-largest lender.
Strategic Stakes and Market Reactions
The competing offers carry major implications for the European banking landscape. Intesa stated that its acquisition proposal would create the second-largest banking group within the eurozone, trailing only Spain’s Banco Santander. Meanwhile, Banco BPM provided few initial details regarding its deal structure, indicating only that the transaction would grant both entities equal weight in the combined enterprise.
Market reaction on Monday saw shares move downward for the prospective buyers while rising for the target. Shares in Intesa fell 4%, Banco BPM shares dropped 1.1%, and MPS shares increased by 0.9% in early trade.
MPS has undergone significant structural shifts in recent years. After receiving a state bailout in 2017, the bank was reprivatized in 2023. It subsequently became a primary driver of consolidation in the Italian banking sector after buying Mediobanca, a transaction that established MPS as the largest investor in insurer Generali.
Political Scrutiny Over Foreign Influence
Banco BPM’s merger approach has triggered political and financial scrutiny due to its ownership structure. The bank’s largest shareholder is French financial giant Crédit Agricole, which holds roughly a 20% stake. Crédit Agricole voiced support for the potential tie-up, stating it was interested in analyzing value creation opportunities to strengthen BPM.

However, critics have raised concerns that a merger involving Banco BPM could offer Paris an indirect pathway into one of Italy’s most strategically sensitive financial institutions. MPS owns a 13% stake in Generali Insurance, which stands as one of Italy’s largest private holders of government bonds. Because of these substantial holdings in domestic debt, the takeover battle carries heavy significance for the broader Italian public beyond conventional banking.
According to reports from the Financial Times, resistance has emerged among figures inside Italy’s government regarding the prospect of heightened French influence over strategic financial assets and government debt. The situation is particularly sensitive for Prime Minister Giorgia Meloni’s nationalist administration, which has pursued an interventionist strategy to shield nationally critical companies from foreign oversight. Reuters noted that Meloni and key allies previously sought to block foreign investors from expanding their control over Generali to preserve domestic leverage within strategic sectors of the national economy.
