For the first time, every long-term debt instrument issued by Banca Monte dei Paschi di Siena carries an investment-grade rating. On 1–2 October 2026, Morningstar DBRS lifted the bank’s Tier 2 subordinated debt to ‘BBB (low)’ from ‘BB (high)’, clearing the final rung that had kept part of the Sienese lender’s capital stack in sub-investment territory. Understanding the MPS DBRS upgrade in full requires looking at these details closely.
The MPS DBRS upgrade is a notable moment in Italy’s current banking consolidation wave, and it was reported by multiple financial outlets. This article summarises what the agency actually did, what it said, and how the move fits into a bigger reshaping of the Italian banking map that gf6.com tracks through its global directory of banks in Italy.
The finding — what Morningstar DBRS actually changed — MPS DBRS upgrade
The rating action covers several instruments at once, and the direction of travel is uniformly positive. Here is what the agency announced on 1–2 October 2026: These figures put the MPS DBRS upgrade into clearer perspective.
- Long-Term Issuer Rating upgraded to ‘BBB (high)’ from ‘BBB’.
- Long-Term Senior Debt Rating upgraded to ‘BBB (high)’ from ‘BBB’.
- Long-Term Deposit Rating raised to ‘A (low)’.
- Tier 2 subordinated debt rating lifted to ‘BBB (low)’ from ‘BB (high)’.
- Outlook on all ratings: stable.
The practical effect is that all of MPS’s long-term debt instruments now sit in investment grade. That matters most for the Tier 2 line, which crossed the line from speculative-grade into IG territory with this action. The original report was published by Borse.it and independently covered by MarketScreener and Capitalist.it.
What it means for MPS and its bondholders
Morningstar DBRS attributed the upgrade to three specific drivers: MPS’s solid H1 2026 operating performance, greater business diversification following the acquisition of Mediobanca, and progress in the integration process. The agency noted that the combined entity formed a new banking group with assets of approximately €230 billion as of end-June 2026. This context matters for anyone following the MPS DBRS upgrade.
Pushing Tier 2 debt from ‘BB (high)’ to ‘BBB (low)’ is the single most consequential piece. Many institutional mandates — insurance portfolios, pension funds, certain index-linked bond funds — cannot hold sub-investment-grade paper. Once the entire capital stack is IG from at least one recognised agency, the pool of eligible buyers for MPS’s subordinated bonds widens, which is generally associated with tighter spreads over time. This is a general market dynamic, not a specific forecast for MPS. It is a central thread in the wider MPS DBRS upgrade.
The agency also flagged, but did not act on, MPS’s twin all-share takeover bids: one for Banco BPM, valued at roughly €25.3 billion, and one for Banca Generali, at around €8.7 billion. Morningstar DBRS said that if completed, these deals could further strengthen market positioning, though it evaluated them separately from the current rating action. In other words, the upgrade reflects where MPS is today after the Mediobanca combination — not where it might be if either further bid succeeds. Such details shaped how the MPS DBRS upgrade unfolded.
Markets took the news in stride rather than celebrating it. Italian financial outlets reported MPS shares were under slight pressure on 2 October 2026, down 1.08% to €11.19, amid broader banking sector volatility. Credit upgrades of this kind are often already partly priced in by the time they are announced, and equity moves on the day frequently reflect sector sentiment rather than the rating action itself. This is one of the defining aspects of the MPS DBRS upgrade.
How this fits the Italian consolidation wave
The upgrade is a credit-market data point inside a much larger structural story. Italy’s banking sector has been reshaping around a handful of larger groups, and MPS — long considered a legacy problem child — has moved from state rescue to acquirer in a strikingly short period. The Mediobanca acquisition is the move that Morningstar DBRS specifically cites as having lifted diversification and scale.
The outstanding bids for Banco BPM and Banca Generali, if successful, would consolidate that transformation further. For the branch and ATM footprint on the ground, consolidation of this scale typically leads to network reviews over the following years — rebranding, overlap closures, and shifts in which towns keep which operator. That is one reason gf6.com tracks branch and ATM locations country by country rather than taking a single snapshot in time.

Methodology
This piece is a plain-language rewrite of a publicly reported credit rating action. The underlying facts — the ratings themselves, the drivers cited by the agency, the group asset figure, the bid valuations, and the intraday share move — come from reporting by Borse.it, with independent confirmation from MarketScreener and Capitalist.it. No figures have been added beyond those in the source reporting.
Context about Italy’s branch and ATM landscape draws on gf6.com’s own curated directory, a four-year project covering roughly 445,000 financial locations worldwide, including a substantial but incomplete sample of Italian branches and cash machines. Coverage varies by country, and the directory is not an official register.
Frequently asked questions
What exactly did Morningstar DBRS change on 1–2 October 2026?
The agency upgraded MPS’s Long-Term Issuer Rating and Long-Term Senior Debt Rating to ‘BBB (high)’ from ‘BBB’, raised the Long-Term Deposit Rating to ‘A (low)’, and lifted the Tier 2 subordinated debt rating to ‘BBB (low)’ from ‘BB (high)’. The outlook on all ratings is stable.
Why is the Tier 2 upgrade the most important part?
Moving Tier 2 subordinated debt from ‘BB (high)’ to ‘BBB (low)’ crosses the line from speculative-grade into investment grade. It means all of MPS’s long-term debt instruments now carry investment-grade ratings for the first time, which generally expands the universe of institutional investors permitted to hold the paper.
What reasons did the agency give?
Morningstar DBRS pointed to MPS’s solid H1 2026 operating performance, greater business diversification following the acquisition of Mediobanca, and progress in the integration process. It noted that the combined banking group had assets of approximately €230 billion as of end-June 2026.
Do the Banco BPM and Banca Generali bids factor into the rating?
No, not in this action. The agency mentioned the all-share takeover bids for Banco BPM (valued at around €25.3 billion) and Banca Generali (around €8.7 billion) and said they could further strengthen market positioning if completed, but it evaluated them separately from the current upgrade.
How did the share price react?
Italian financial markets reported MPS shares were under slight pressure on 2 October 2026, down 1.08% to €11.19, amid broader banking sector volatility. Rating upgrades are often partly priced in before they are announced, and day-of equity moves can reflect sector sentiment rather than the action itself.
Does this change ratings from other agencies?
No. This is a Morningstar DBRS action only. Other credit rating agencies maintain their own independent assessments of MPS, and those are unaffected by this specific upgrade.
