Piraeus Bank: The NII Upgrade Rests on a Deposit Flywheel It Only Half-Owned Last Quarter
Record core profit and raised 2027 ambitions, but the swing factor is deposit growth, a held-for-sale clean-up, and a buyback that quietly vanished
TPEIR.AT · Earnings Call · 2026-10-30
Piraeus Bank did not simply beat and raise. The Greek lender's 9M 2026 call was a lesson in how a bank can upgrade guidance while quietly changing what drives the P&L. Record core operating profit of €930 million, EPS of €0.68 and a 15.4% return on tangible book value are the headline. But the real news is that deposit growth—not loan growth—has become the swing factor in net interest income, that a €50 million held-for-sale clean-up has de-risked 2027, and that a buyback management once framed as an annual option has disappeared from the capital-return story.
The NII upgrade is a deposit flywheel—until it isn't
Piraeus grew its loan book 8% year-on-year to €40 billion and delivered €2.2 billion of net credit expansion in the nine months, putting it on track for more than €3 billion for the full year. That is strong, and management still leans on the familiar best-in-class cost-to-income ratio of 33% to sell the equity story. But the more important number is the 7% quarter-on-quarter jump in net interest income and the 2.3% net interest margin. CFO Theo Gnardellis was explicit that the deposit side did the heavy lifting: the ratio of deposit delta to loan delta ran above 130% in 2026 versus a 60% plan assumption. That is a massive tailwind for the NIM outlook, and it is why 2027 NIM guidance moved to more than 2.4%.
CEO Christos Megalou framed the deposit inflow as a structural shift rather than a quarterly quirk:
We think this is the beginning of a new trend. We saw EUR 3 billion deposits -- net flow deposit this year... a large part of it has to do with funds being repatriated into the Piraeus deposit base.
That is a more confident claim than the one he made in July. Asked then about the strong deposit growth, Megalou attributed “about 50%... to this corporate activity and the other 50% of the growth was organic” — Christos Megalou, Chief Executive Officer · 2026-07-29. Six months later, the same flow is being described as the start of a repatriation trend. It may well be true—Greece's improving macro, declining debt ratios and European funding flows are real—but the base case now leans on a deposit flywheel that was partly corporate-driven only a quarter ago. If it persists, Piraeus's core deposits franchise deserves a higher multiple; if it fades, the NII upgrade is more cyclical than structural.
The loan mix adds a second wrinkle. Shipping drove more than 40% of net credit expansion in the first nine months and now represents about 10% of group loans. Megalou defended the book—LTV around 50%, conservative client selection—but was careful not to extrapolate:
“This is not like we cannot say that this is a trend for next year because all our work and analysis is coming on a year-for-year basis, recognizing that this is a cyclical business.” — Christos Megalou, Chief Executive Officer · 2026-10-30
For 2027, the replacement growth is meant to come from hospitality, infrastructure, construction and energy. That is a sensible rotation, but it also means the loan-growth story is more concentrated than the headline 8% suggests.
The 2027 clean-up: held-for-sale today, cleaner cost of risk tomorrow
Asset quality looks excellent: the NPE ratio fell to 2.0% from 2.2%, and organic cost of risk came in at 57 basis points. But the improvement was helped by a deliberate €50 million provision to move a bucket of loans into held-for-sale status. The holding for sale portfolio was a mix of existing NPEs and accounts that were going sour; Piraeus added provisions and pulled the pain forward. Gnardellis was unusually candid about the motive:
“The 2027 P&L does not have any cost of risk budgeted for sale. It's one of the reasons why we did it.” — Theodore Gnardellis, Chief Financial Officer · 2026-10-30
That is legitimate balance-sheet management, not a scandal. It creates a cleaner 2027 base and reduces the chance of a repeat of the Katseli-law-related cost-of-risk upgrade that hit the second quarter. But it also means the 2027 cost-of-risk guidance is flattered by a 2026 action. Investors should treat the 57 basis points as a cleaner underlying run rate only after adjusting for the held-for-sale charge. The contrast with July is subtle but real: then, the CFO said the move from 50 to 60 basis points reflected Katseli and macro adjustments, and that “I would not move on any part of the guidance for the upcoming years” — Theodore Gnardellis, Chief Financial Officer · 2026-07-29. The held-for-sale bucket is the mechanism that lets him keep that promise.
The other source of P&L noise is the trading book, which is larger than at some peers because Piraeus is a top market-maker in Hellenic Republic paper and a primary dealer in NGEU. The book is rate-hedged, but credit-spread moves still hit reported earnings. Gnardellis called the third-quarter volatility a one-off and said the fourth quarter is so far flat:
“It's fully hedged for interest rate risk, but still a credit spread movement can create some P&L volatility that we have experienced in the previous quarters.” — Theodore Gnardellis, Chief Financial Officer · 2026-10-30
This is why management wants investors to focus on core operating profit rather than reported EPS. Fair enough—but it also means the headline “conservative” 2027 EPS growth of roughly 10% carries more mark-to-market risk than a pure commercial bank.
Capital options: Danish Compromise is priced by analysts, not by management
CET1 rose 10 basis points quarter-on-quarter to 12.9%, and Piraeus still targets above 13% for 2026 and above 13.5% for 2027. The CFO insisted the 2027 path is pure organic capital generation, with no reliance on the Danish Compromise. That is a notable shift in specificity: the compromise—Article 49 of CRR3—would add about 70 basis points of CET1 given the current balance sheet, but Gnardellis said it is “not in the short-term aspirations, nor is that the objective of getting FICO status” — Theodore Gnardellis, Chief Financial Officer · 2026-10-30. In May 2025, the same topic was described as “not in play and not in any, I would say, plan A calculations” — Theo Gnardellis, Chief Financial Officer · 2025-05-10. The option has moved from hypothetical to quantified, yet remains outside guidance. Conservative, yes—but analysts will likely capitalize some of that 70 basis points anyway.
The bigger surprise is the buyback. Asked whether the 10% EPS growth aspiration includes repurchases, Megalou was blunt: “the distribution is all cash, Osman... the earnings per share outlook... is a conservative number.” — Christos Megalou, Chief Executive Officer · 2026-10-30 That is a clear break from the tone of prior calls. In July 2025, the CEO said a buyback was something the bank “would like to be in a position to take on an annual basis, depending on where our share price stands at tangible book value” — Christos Loannis Megalou, Chief Executive Officer · 2025-07-31. Piraeus did execute a €100 million buyback in 2025. Now, despite a 15.4% ROTE and management's own view that the shares trade below European peers with similar earnings, the cash dividend is the only tool on the table. That may be a preference for a strong cash yield, or a signal that regulators want capital retained; either way, the EPS lever that a buyback would provide has been removed.
What the market is really being asked to believe
Piraeus's bull case is no longer just “Greek bank recovery.” It is that deposit repatriation is structural, that the 2027 cost-of-risk base is genuinely clean, that the services over assets slowdown is mostly a bancassurance accounting reclassification—roughly €50 million of nominal fee headwind as upfront commissions become amortized insurance contributions—and that capital options like the Danish Compromise are nice-to-haves rather than necessities. Each claim is plausible. Together, they ask investors to look through several moving parts: a shipping-heavy loan book, a volatile trading book, a held-for-sale clean-up and an all-cash payout.
The call was strong enough to justify the raised 2027 ambitions. But the quality of the beat matters more than the size. If deposits keep growing faster than loans and the Greek economy stays resilient, Piraeus has a genuine NII flywheel and a path to a higher valuation. If the deposit surge was partly corporate repatriation that normalizes, the upgrade is more cyclical—and the absence of a buyback leaves less cushion for the EPS story. That is the debate the market now has to price.
