Banca Monte dei Paschi di Siena has completed its inaugural green bond issuance, pricing a EUR 500 million six-year senior preferred unsecured note on 13 November 2025 with a coupon of 3.25% and a maturity date of February 2032. The transaction drew approximately EUR 2 billion in orders, representing around four times the deal size, and priced at a spread of 90 basis points above mid-swap — some 30 basis points tighter than the initial guidance communicated to investors when the book was opened.
The strong oversubscription and material spread compression mark a notable milestone in the Siena-based lender's ongoing rehabilitation. The bond was issued under the bank's 2024 Green, Social and Sustainability Bond Framework, which established the governance structure necessary for BMPS to enter the labelled sustainable finance market.
FOUR TIMES OVERSUBSCRIBED AT FINAL PRICING
The EUR 2 billion order book that supported the EUR 500 million print reflected a competitive bookbuilding process in which demand comfortably outstripped supply. Investors from across Europe participated, with the final allocation distributed geographically as follows: Italy took 36% of the book, the DACH region accounted for 17%, France for 15%, and Southern Europe for 13%. The remaining allocation was distributed among other European institutional buyers, demonstrating the transaction's reach beyond BMPS's domestic investor base.
The 30-basis-point tightening from initial guidance to final pricing terms illustrates the substantial pricing power that a heavily oversubscribed order book confers on an issuer. In practical terms, BMPS was able to raise its EUR 500 million at a lower cost than the opening guidance implied, a direct financial benefit of the strong investor demand. For a bank that has navigated a prolonged restructuring, pricing a debut green bond at levels that outperformed initial expectations is a meaningful statement about its standing in European capital markets.
Senior preferred unsecured instruments of this type sit within a bank's funding hierarchy in a position that ranks ahead of subordinated and Tier 2 instruments in a resolution scenario, making them relatively accessible for a broad range of institutional investors, including those operating under investment-grade mandates that preclude subordinated paper.
ISSUED UNDER 2024 SUSTAINABILITY FRAMEWORK
BMPS established its Green, Social and Sustainability Bond Framework in 2024 to provide the governance architecture necessary to enter the labelled bond market in a credible and verifiable manner. The November issuance is the first green tranche executed under that framework, with proceeds directed toward eligible green assets identified by the bank in line with the framework's stated criteria. The framework gives investors assurance that allocated funds will be tracked and reported against defined environmental categories.
The successful debut opens a new and potentially recurring funding avenue for BMPS and diversifies its investor base beyond the institutions that participate in conventional senior or subordinated issuance. ESG-dedicated funds and sustainability-linked mandates represent a distinct pool of capital with specific reporting requirements, and by meeting those requirements through its framework and annual reporting obligations, BMPS positions itself to access that pool on a repeated basis. Should the green bond programme continue to attract the oversubscription levels seen in this inaugural deal, the bank can expect to return to the market in future years, progressively broadening both the scale of its sustainability commitments and the depth of its relationships with dedicated ESG investors across Europe.
