The public offer launched by Intesa Sanpaolo to acquire Monte dei Paschi di Siena represents one of the most important operations in recent years in the Italian financial landscape. The overall value of the operation, equal to 30.6 billion euros, does not only concern the fate of one of the oldest banks in the world, but is destined to change the balance of the national credit sector, with effects that involve large groups such as Unipol, BPER, Mediobanca and Generali and which could also change the daily experience of millions of banking customers.
Why Intesa Sanpaolo wants to buy MPS
Although the launch of a voluntary takeover and exchange offer (Opas) on all the shares of Monte dei Paschi di Siena (MPS) was announced on 8 June 2026, the operation has not yet been formally concluded, as the process involves several phases and requires the necessary regulatory and shareholder approvals. However, if the acquisition were to be completed, Intesa would become Generali’s main shareholder with an overall stake close to 16%, further consolidating its position in the Italian financial market.
Through this operation Intesa Sanpaolo aims to increase its size but also to strengthen its presence in the managed savings, insurance and investment sectors.investment banking. Furthermore, the group led by Carlo Messina would once again become the first Italian bank by market value, overtaking UniCredit and strengthening its leadership also at a European level.
The terms of the offer and the agreement with Unipol
The proposal involves the exchange of 16 Intesa Sanpaolo shares for every 10 MPS shares, with the addition of one euro in cash for each MPS share. The offer is conditional on reaching at least 66.67% of MPS’s capital (source: Intesa Sanpaolo).
To prevent Antitrust issues, Intesa Sanpaolo has signed a binding agreement with Unipol Assicurazioni. The latter involves the subsequent sale of an autonomous banking entity which will include the historic MPS brand and approximately 635 branches. Intesa Sanpaolo will instead maintain approximately 625 branches in the MPS perimeter.
The preliminary calendar indicates that the filing of the offer document is scheduled for the end of June 2026, while the extraordinary meeting of Intesa Sanpaolo shareholders to approve the capital increase will be held on 10 September 2026. The actual start of the offer is estimated between the end of September and December 2026.
What changes for customers
For account holders, the most important news is that, in the immediate future, absolutely nothing changes. The operation will in fact have to obtain all the authorizations required by the supervisory authorities and will require long technical times before becoming operational.
During this phase:
- current accounts will continue to function normally;
- the Ibans will remain unchanged;
- credit and debit cards will continue to be usable;
- bank debits and salary or pension credits will not be changed;
- the economic conditions signed by customers will remain valid.
Those who have an account with MPS or Intesa Sanpaolo will therefore not have to carry out any operations and will be able to continue using the services as usual.
Mortgages and loans: contracts remain unchanged
Even on the financing front, the protections provided by the legislation are very clear. A merger or corporate acquisition does not allow the bank to unilaterally modify the contractual conditions already signed.
For this reason:
- the mortgage interest rate will remain the one originally agreed;
- duration and repayment plan will not be changed;
- the amount of the installments will remain unchanged;
- the guarantees provided for by the contract will continue to be effective.
The same principle also applies to personal loans, salary-backed loans and other loans already granted. The contractual obligations pass to the new banking entity without altering the customer’s rights.
What could change in the coming years
However, not everything will remain unchanged. In fact, the effects of the operation will be visible above all in the medium-long term. Once the integration between the various entities involved is complete, a rationalization of the commercial networks and banking offering is likely.
This could translate to:
- review of product catalogues;
- unification of commercial offers;
- integration of digital platforms;
- closure of overlapping branches in the same geographical areas and consequent strengthening of online services and financial consultancy.
The industrial objective is in fact to create more efficient groups, with greater economies of scale and a more rational territorial presence.
Furthermore, according to the industrial project, the branches sold to Unipol will merge together with Bper into a new bank which will maintain the historical name of Banca Monte dei Paschi di Siena. The BPER brand would therefore be destined to disappear, while the MPS brand would continue to exist as the commercial sign of the new reality.
Widiba will also be progressively absorbed into the new corporate structure, while the financial consultancy and wealth management activities will be integrated with those coming from Mediobanca.
Which customers switch to Intesa
For Monte dei Paschi customers, the future will depend on the branch they belong to. Part of the network will enter directly into the Intesa Sanpaolo universe, while the customers of the 635 branches destined for Unipol will flow into the new Banca Monte dei Paschi created from the integration with BPER.
However, these are changes which, if the operation is approved, will be accompanied by specific communications to customers and transition periods designed to guarantee operational continuity.
