What changed in June, and what did not in July
On 11 June 2026 the ECB raised its three key interest rates by 25 basis points, taking the deposit facility rate to 2.25% with effect from 17 June. It was the first increase since September 2023, and the Governing Council pointed to inflationary pressure coming through energy prices. At its following meeting on 23 July the Council left all three rates unchanged, with the deposit facility still at 2.25%, describing the energy outlook as close to the baseline in its June projections but with uncertainty still elevated.
So the picture as of late July 2026 is one increase followed by a pause, not the start of a confirmed climb. That distinction matters for a rate decision, because a single hike followed by a hold is a much weaker argument for locking everything down than a sustained upward path would be.
How the two structures actually work in Greece
A floating Greek mortgage is quoted as a benchmark plus a bank spread. Greek lenders commonly reference three-month Euribor for the floating leg, and the rate you pay resets as that benchmark moves, while the spread stays fixed for the life of the loan. The spread is the part you negotiate. The benchmark is the part nobody controls.
A fixed-rate offer in Greece usually means fixed for an agreed initial period rather than for the whole term. Three, five, seven and sometimes ten years are the common options, after which the loan reverts automatically to the floating formula. Some lenders will quote a rate fixed for the full term, but that is the exception rather than the default, and it is normally priced accordingly.
The practical consequence is that in many Greek offers you are not choosing between fixed and floating. You are choosing how long to defer floating, and on what terms it starts when the fixed period ends.
Read the reversion terms, not just the headline rate
Because most fixed offers revert, the number that decides the second half of your mortgage is the spread that applies after the fixed period, not the promotional rate that applies during it. An attractive introductory fixed rate paired with a wide reversion spread can cost more over twenty years than a plainer offer with a narrower one.
Ask each lender for three figures in writing: the fixed rate and its exact duration, the benchmark used for the floating leg, and the spread that will be added to that benchmark afterwards. If a quote will not give you the third figure clearly, that is worth noticing in itself.
Where the benchmark sits at the moment
Euribor moved up alongside the June decision. Twelve-month Euribor was around 2.98% in the final week of July 2026, having started June closer to 2.76%. Three-month Euribor, the reference most often used for Greek floating mortgages, sits on its own path and should be checked separately rather than assumed to match.
Two things follow. First, a floating rate quoted today is not the floating rate you saw quoted in spring. Second, a fixed quote issued before June may already have been repriced, so refresh any offer you collected earlier in the year before comparing it against anything new.
The non-resident starting point is different
Whichever structure you pick, a US buyer generally starts from tighter parameters than a Greek resident. Loan-to-value for non-residents typically runs around 60% to 70%, against a higher ceiling for residents, and lenders often apply a modest rate premium as well. Terms can be shorter, and documentation requirements are heavier.
That affects the fixed-versus-floating question indirectly but genuinely. A larger deposit means a smaller loan, which means each percentage point of rate movement moves your monthly payment by less in absolute terms. Buyers who are financing a small proportion of the purchase price sometimes over-engineer the rate decision when the amount at stake is modest.
Keep rate risk and currency risk in separate columns
If you earn in dollars and the mortgage is in euros, you are carrying two independent exposures. Fixing your interest rate stabilises the euro amount of your payment. It does nothing to stabilise what that euro amount costs you in dollars, which depends on an exchange rate that has moved substantially in recent years.
This is worth stating plainly because the two get merged in conversation, and a fixed rate can create a false sense that the payment is now predictable. The euro figure is predictable. The dollar figure is not. If currency movement is the exposure that actually worries you, a fixed rate is not the tool that addresses it.
Early repayment changes the calculation
Buyers who expect to repay a Greek mortgage early, whether from a US property sale, a maturing investment or a planned relocation, should treat early-repayment terms as part of the rate decision rather than a footnote. A charge is more likely to apply during a fixed period than on a floating loan, and Greek mortgage credit rules place limits on what a lender may charge.
The general shape is that flexibility and rate certainty pull against each other, and the right balance depends on how firm your repayment plan really is. Ask your lender to state the early-repayment charge for each option in writing, for a partial repayment and a full one, before you choose between them.
How to reach a decision you can defend
Start from your own position rather than from a forecast. How long do you realistically expect to hold the property and the loan? How much monthly variation could you absorb without changing anything else? Is a repayment likely in the first few years? Those three answers narrow the field faster than any view on where the ECB goes next.
Then compare complete offers rather than headline rates: fixed rate and duration, reversion spread, benchmark, fees, and early-repayment terms, for the same loan amount and the same term. A structure that suits a buyer who is relocating permanently and repaying slowly is rarely the same one that suits a buyer who expects to clear the loan in five years.
Practical checklist
- Ask whether the fixed rate applies for a period or for the full term.
- Get the reversion spread in writing, not just the introductory rate.
- Confirm which Euribor tenor the floating leg references.
- Refresh any quote issued before the June 2026 decision.
- Check the early-repayment charge for both partial and full repayment.
- Treat currency exposure as a separate question from rate structure.
- Compare offers on the same loan amount, term and fee basis.
