Intesa Sanpaolo filed its voluntary public tender offer document with Consob for all outstanding shares of Banca Monte dei Paschi di Siena, setting a December 2025 completion target. The filing converts eighteen months of Ministry of Economy negotiations into binding procedure. Italy's largest bank now owns the regulatory clock on absorbing the world's oldest continuously operating lender, founded 1472.
The tender formalizes Intesa's acquisition of the Italian state's 11.7% residual stake and minority float in MPS, following three prior rescue attempts since the €5.4 billion state bailout in 2017. Consob review typically runs 25 to 30 business days before offer approval, placing the acceptance window in mid-to-late Q4 2025. Monte dei Paschi holds €165 billion in assets under management, primarily retail and SME exposure across Tuscany and Lazio. Intesa's document specifies no financing condition — the €13.3 billion Tier 1 capital base covers the residual equity purchase and integration reserve.
The filing matters because it closes the Italian sovereign's longest post-crisis banking exposure. The Ministry of Economy converts its 64% MPS stake — acquired through 2016-2017 recapitalizations — into Intesa equity and cash, removing €8.6 billion in contingent liability from state books before the 2026 budget cycle. Intesa inherits MPS's 1,400-branch network, the second-densest footprint in the Mezzogiorno after Banco BPM. The combined entity controls 23% of Italian household deposits and 18% of business lending below €5 million ticket size. Brussels approved the merger in October 2024 under state-aid clearance, requiring no branch divestitures — a reversal from the 2017 UniCredit negotiation, which collapsed on EU Competition demands for 500-store spin-offs.
The second-order effect runs through Italy's last two independent mid-cap banks. Banco BPM and BPER Banca now face a €900 billion balance-sheet competitor with 4,200 branches and cost-of-capital advantages no standalone Italian lender can match. Intesa models €700 million in annual cost synergies by 2027, primarily MPS headcount reduction and IT infrastructure shutdown. The Siena headquarters — a Renaissance palazzo employing 1,100 staff — converts to regional office status. Monte dei Paschi's €18 billion NPL book, cleaned to 3.2% gross after four state-led disposals, folds into Intesa's €31 billion distressed platform. Allocators watching Italian financials now price a three-player oligopoly instead of five.
Operators and allocators should monitor Consob's approval timing in the second half of November, which sets the formal acceptance window. The tender requires 66.67% acceptance to trigger squeeze-out provisions under Italian corporate law — watch for hedge-fund holdout positioning in the 8.3% free float during the first ten trading days of the offer. The Ministry of Economy's conversion of its MPS stake into Intesa shares hits the market in early January 2026, creating a €2.1 billion secondary overhang that typically trades at 90-basis-point discounts to spot in prior Italian bank privatizations. Brussels releases its annual state-aid compliance report in March 2026 — the first post-merger filing that confirms or disputes Intesa's synergy math.
The Consob document is the opinion. Italy just filed the paperwork to erase its oldest banking mistake, and the world's oldest bank becomes a footnote in someone else's investor deck by New Year.
