Bidding War Erupts for Monte dei Paschi, World's Oldest Bank

Banca Monte dei Paschi di Siena, founded in 1472 and the oldest operating bank in the world, became the center of Italy's largest-ever banking deal over a single weekend in June 2026. What began as a genteel merger proposal from Banco BPM on Saturday turned into a full-scale bidding war by Monday morning, when Intesa Sanpaolo — already Italy's biggest bank — launched an unsolicited €30.6 billion cash-and-share offer to swallow MPS whole [1][2].

The fight for MPS is about far more than one troubled Tuscan bank. It touches the balance of power across Italian finance: retail banking, insurance, wealth management, and the political question of how much consolidation one country's financial system can absorb before competition suffers and communities lose their lender of last resort.

The Weekend That Upended Italian Banking

On June 7, 2026, Banco BPM's board unanimously approved a proposal to open merger discussions with MPS, describing the combination as a "merger of equals" that would create Italy's second-largest banking group with a combined market capitalization exceeding €50 billion [3][4]. The proposed entity would surpass UniCredit in size and trail only Intesa Sanpaolo domestically.

Less than 24 hours later, Intesa CEO Carlo Messina preempted the move. Intesa filed a voluntary public tender and exchange offer for 100% of MPS's share capital, offering 16 newly issued Intesa shares for every 10 MPS shares, plus €1 in cash per share — valuing each MPS share at €10.09 [5][6]. That represented a 12.5% premium to MPS's closing price of €8.97 on June 5 and a 17.4% premium to the three-month volume-weighted average [7].

"If someone is prepared to offer more than we are offering, then there could be competition," Messina said, signaling his readiness for a fight [1].

Under Italian takeover rules, Intesa's formal bid now prevents MPS from agreeing a deal with BPM without prior shareholder approval [2].

The Price Tag of a Decade of Bailouts

MPS's path to the auction block has been paved with taxpayer money. In 2017, the Italian government injected €5.4 billion into the bank as part of a precautionary recapitalization under EU state-aid rules, taking a 68% ownership stake [8]. That bailout followed years of losses tied to disastrous derivative trades, a scandal-plagued acquisition of Banca Antonveneta, and a portfolio choked with non-performing loans.

The total public cost extended well beyond the 2017 injection. Including earlier capital raises backed by state guarantees, burden-sharing imposed on junior bondholders (many of them retail investors who were subsequently compensated by the state), and the cost of managing MPS's bad-loan transfers, estimates of the cumulative taxpayer exposure range from €8 billion to over €10 billion [8][9].

The Italian Treasury has since clawed back a significant portion of that investment through a series of share sales. Between late 2022 and 2024, Rome sold down its stake from 64% to approximately 11.7%, generating just over €4 billion in proceeds [9]. By early 2025, Prime Minister Giorgia Meloni declared that "Rome's role in MPS had ended," with the remaining government stake reduced to roughly 4.9%, worth approximately €1.36 billion at market prices at the time [9].

Under Intesa's bid, which values MPS at €30.6 billion total, the government's 4.9% residual stake would be worth approximately €1.5 billion. Combined with the €4 billion-plus already recovered through earlier sales, taxpayers would recoup roughly €5.5 billion — still short of the original €5.4 billion cash injection alone, before accounting for the broader costs of guarantees and bondholder compensation [9][5].

The Bidders and What They Want

Intesa Sanpaolo: The Dominant Player Gets Bigger

Intesa's offer would create the eurozone's second-largest banking group by market value after Spain's Santander, with a combined market capitalization of roughly €126 billion, approximately €1.7 trillion in assets, over 27 million clients, and around 3,000 branches [5][10]. Intesa projects the merged entity would generate net income exceeding €16 billion by 2029, with a return on equity above 20% [7].

The projected synergies are substantial: €2.9 billion annually by 2029, broken down into approximately €1.5 billion in cost savings and €1.4 billion in revenue gains [5][7]. Intesa expects the deal to deliver earnings-per-share accretion of 8% from the third year onward [7].

But there is a deeper strategic motive. MPS acquired rival investment bank Mediobanca in 2025, which handed it a roughly 13% stake in Assicurazioni Generali, making MPS the largest single investor in Italy's premier insurance company [11][12]. By acquiring MPS, Intesa would effectively gain influence over Generali — a prize that has been at the heart of Italian financial power struggles for decades. Intesa's board separately approved purchasing an additional 3.01% stake in Generali to maintain equity accounting treatment for its share of Generali's earnings [12].

Banco BPM: The Merger of Equals

Banco BPM's proposal, while less dramatic in headline value, offers a fundamentally different vision. Rather than absorption by a dominant player, BPM proposed a combination in which both institutions would retain "balanced influence" [3][4]. The merged group would have estimated annual pre-tax synergies of over €1.1 billion — €650 million from cost reductions and €450 million from revenue enhancement — and a projected run-rate net profit of approximately €6 billion [4].

BPM's board, which includes representatives of its largest shareholder, France's Crédit Agricole, unanimously backed the proposal. Crédit Agricole separately signaled it was "interested in analyzing value creation opportunities which can strengthen BPM," a statement interpreted as endorsing the merger approach [2][3].

The BPM path would preserve MPS's institutional identity and, potentially, its operational footprint in Tuscany more fully than absorption into Intesa.

The Unipol-BPER Side Deal

A third actor has entered through the side door. To address antitrust constraints — Intesa already commands roughly a fifth of the Italian domestic market after its 2020 acquisition of UBI Banca — Intesa struck a pre-arranged agreement with insurer Unipol [10][13]. If the bid succeeds, Intesa would divest 635 MPS branches (roughly half the retail network) along with MPS's central offices in Siena and the MPS brand name to Unipol, which would fold them into BPER Banca. The branch package is valued at €3 billion to €3.5 billion [10][13].

The resulting entity would operate under the name "Banca Monte dei Paschi," preserving the world's oldest banking brand even as the institution itself is carved up [1][13]. Unipol played the same role in Intesa's 2020 UBI acquisition, purchasing divested branches to satisfy competition authorities [10].

What Happens to 17,000 Jobs

MPS employed roughly 16,800 people as of its most recent disclosures, down from approximately 21,000 in 2020 after successive rounds of restructuring [14]. The workforce question is central to the political acceptability of any deal.

Intesa has framed its plan carefully: 6,800 "voluntary departures" offset by an equivalent number of new hires by 2029, producing what the company characterizes as a net-neutral workforce impact [10]. In practice, the departures would likely be concentrated among back-office and overlapping administrative functions, while new hires would be oriented toward revenue-generating roles. The voluntary nature of the departures — typically achieved through early retirement incentives — is designed to defuse union opposition, though the net effect on employment in specific regions, particularly Tuscany, remains uncertain.

Banco BPM's merger-of-equals structure would, by design, produce fewer redundancies because the integration would be less aggressive. BPM has estimated cost synergies of €650 million, compared to Intesa's €1.5 billion — a gap that implies significantly fewer job cuts under the BPM scenario [4][5].

For Siena and the broader Tuscan economy, the stakes are acute. MPS is not just the largest private employer in Siena — it is a civic institution whose operations, charitable foundation, and local spending have shaped the city for over five centuries. The Unipol side deal, which would retain MPS's central offices in Siena, is a direct acknowledgment of this political reality [13].

Regulatory and Antitrust Hurdles

Both bids face significant regulatory scrutiny. The Italian Competition Authority (AGCM) must approve any transaction, and the European Central Bank — as MPS's prudential supervisor — holds effective veto power over changes to the bank's ownership structure [10][15].

For Intesa, the primary concern is domestic market concentration. Having already absorbed UBI Banca in 2020, Intesa controls the largest share of Italian deposits and loans. Adding MPS's full branch network would almost certainly trigger antitrust objections, which is why the Unipol branch divestiture was negotiated in advance [10][13]. Whether the AGCM and the European Commission consider the remedy sufficient remains an open question. The Commission's competition branch has already shown heightened interest in MPS-related transactions, having launched scrutiny into the Italian government's November 2024 share sale process over concerns that some investors were excluded [16].

For Banco BPM, the antitrust picture is cleaner. A BPM-MPS combination would create Italy's second-largest bank but would not approach the market dominance Intesa already holds, reducing the likelihood of forced divestitures [15].

Both transactions require ECB approval, conditioned on capital adequacy, governance standards, and integration plans. The ECB has historically been supportive of European banking consolidation as a means to build more resilient institutions, but has also flagged execution risk in cross-border and large domestic mergers [15].

Crédit Agricole's involvement adds a cross-border dimension. As BPM's largest shareholder, the French bank would become a major stakeholder in the combined entity, potentially raising questions about whether the "merger of equals" is truly a domestic consolidation or a backdoor for French banking influence in Italy [2][3].

The Case for MPS Staying Independent

The bidding war has emerged precisely because MPS has finally become attractive again. After years as a ward of the state, the bank returned to profitability, completed its acquisition of Mediobanca, and saw its share price rise over 21% in the three months preceding the bids [7]. Its market capitalization of €27.4 billion on the eve of Intesa's offer reflected genuine investor confidence, not just speculative positioning [5].

This turnaround is the strongest argument against a sale. If MPS can generate sustainable profits as an independent institution — especially one that now controls Mediobanca's investment banking franchise and a commanding stake in Generali — then selling it to Intesa at a 12.5% premium could destroy more long-term value than it creates. Banking analysts at Bankinter characterized the premium as modest, observing that MPS's recent share price gains already exceeded the premium being offered [7].

Italy's experience is not unique. Germany's handling of Commerzbank, which received a state bailout during the 2008 financial crisis, offers a counterpoint. Berlin has resisted UniCredit's €35 billion hostile bid, with Chancellor Friedrich Merz calling a foreign takeover "unacceptable" and arguing that Commerzbank should remain independent [17]. The German government retains its stake and has prioritized national banking sovereignty over a quick exit.

Spain's Bankia-CaixaBank merger in 2020 provides the opposite lesson. The Spanish government, which held a majority stake in bailed-out Bankia through its restructuring fund FROB, used the merger with CaixaBank to reduce its position and create Spain's largest domestic lender [18][19]. The transaction prioritized consolidation and taxpayer recovery over preserving Bankia as a standalone institution — and was widely viewed as successful in stabilizing Spain's banking sector, though taxpayer recovery on the original bailout costs remained incomplete [18].

Italy's path with MPS falls somewhere between these models. Rome has already recovered a substantial portion of its investment through share sales, and the remaining 4.9% stake gives it less leverage — but also less reason to force a sale at a price that may undervalue MPS's improved fundamentals [9].

Second-Order Consequences: Tuscany's SME Economy

Beyond employment, MPS's role as the dominant lender to Tuscany's small and medium-sized enterprises makes any change in ownership a regional economic event. The bank serves approximately 3.9 million customers across Italy, with a concentration in Tuscany where it has historically been the primary banking relationship for tens of thousands of local businesses [14].

Neither bidder has made binding commitments to maintain regional lending volumes as a condition of the deal. Intesa's plan to divest 635 branches to Unipol/BPER would preserve a retail banking presence under the MPS name, but whether a Unipol-managed branch network would maintain the same lending appetite for Tuscan SMEs — which carry higher risk profiles and require more relationship-intensive underwriting — is uncertain [13].

Under the Banco BPM merger, the preservation of MPS's institutional identity could more plausibly translate into continuity of regional lending practices, though BPM has offered no specific guarantees on lending volumes [3][4].

Italian banking unions and regional political figures are likely to demand enforceable lending commitments as a condition of any regulatory approval — a mechanism that has precedent in Italian banking M&A but is difficult to enforce over time.

What Comes Next

MPS's board confirmed receiving Banco BPM's proposal and indicated it was awaiting a formal board meeting to evaluate competing offers [4]. Intesa's bid is conditional on acquiring at least 66.67% of MPS's share capital and receiving antitrust clearance, with a target completion date of December 2026 [5][6].

The Italian government, despite its reduced 4.9% stake, retains outsized political influence. Prime Minister Meloni's government has promoted banking consolidation as part of broader plans to raise €19 billion from state asset sales through 2028 [9]. But the political sensitivity of MPS — with its deep roots in the traditionally left-leaning Tuscan electorate and its symbolic weight as the world's oldest bank — means no government can afford to appear indifferent to the outcome.

Messina has left the door open to raising Intesa's offer. Banco BPM may formalize its own bid. Crédit Agricole could deepen its involvement. And UniCredit, which considered and rejected a bid for MPS in 2021, may yet re-enter the picture, particularly given its thwarted ambitions for Commerzbank [17].

For a bank that has been rescued, restructured, and propped up for the better part of two decades, the irony is sharp: MPS is now so attractive that Italy's biggest financial institutions are fighting over it. The question is whether the institution that emerges from this contest will still serve the communities that sustained it through its darkest years — or whether the world's oldest bank will become just another line item on a conglomerate's balance sheet.
