With French government bond yields close to 3.9% and mortgage rates around 3.2%, Fairway analyses this gap and its consequences for buyers and sellers in Paris.
The French real estate market is currently facing an unusual situation. While French government bond yields have risen significantly, mortgage rates offered to individual borrowers have remained relatively stable.
As of July 14, 2026, the TEC 10, a benchmark representing the yield on French government borrowing over ten years, stood at 3.88%, compared with 3.65% at the beginning of the month. At the same time, the average rate on new mortgage loans excluding renegotiations stood at 3.21% in May, according to the Banque de France. The Crédit Logement/CSA Observatory reported an average rate of 3.25%.
How can a bank offer a twenty-year mortgage at a rate lower than the yield on ten-year French government debt? Does this situation mean that mortgage rates will inevitably rise? And should buyers accelerate their property search in Paris?
Fairway Luxury Real Estate analyses the gap between long-term market rates and mortgage rates to help buyers and sellers better understand the factors currently influencing property financing in Paris.
The ten-year French government bond yield is often presented as the benchmark used by banks when setting their mortgage rate schedules. The comparison is relevant, but incomplete.
The TEC 10, published by Agence France Trésor, represents the actuarial yield of a theoretical French government bond with exactly ten years remaining until maturity. It provides an indication of long-term interest rate levels in France and of the cost at which the French State can borrow over that period.
However, it does not represent the direct funding cost of every mortgage granted by a bank.
Banks finance their activities through several sources, including sight deposits, regulated savings, term deposits, bond issuance, market refinancing and hedging operations. Deposits collected from customers represent a significant part of the French banking system's funding resources.
The comparison is also imperfect from a financial perspective. A government bond is generally repaid at maturity, whereas a mortgage is progressively amortised. With every monthly payment, the borrower repays part of the principal, meaning that the amount exposed to risk decreases throughout the life of the loan. There is therefore no formula allowing one to conclude that a government bond yield of 3.80% should automatically result in a mortgage rate of 4.80%.
Mortgage lending continues to play an important commercial role for banks. It allows them to establish a long-term relationship with a client who may transfer their income, savings and other financial activities to the institution.
This strategy is particularly relevant for borrowers with stable incomes, substantial financial savings or an already established level of wealth. In such cases, the bank does not assess only the immediate profitability of the mortgage: it considers the overall banking relationship.
The French universal banking model is based on several sources of revenue. The performance of major banking groups is supported by net interest income, fees and commissions, asset management and insurance activities.
Competition also plays a role. During the first quarter of 2026, general terms and conditions for mortgage lending remained broadly stable, while lower margins on average loans and changes in offered rates contributed to easing certain lending conditions.
Banks may therefore accept reduced margins on certain applications in order to maintain lending volumes, win new customers or prevent their best clients from moving to competing institutions. This does not necessarily mean that they are lending at a loss: their actual cost of funding depends on the structure of their balance sheet, the resources available to them and the way they manage interest rate risk.
The average rate published by the Banque de France is a national indicator. It does not necessarily correspond to the rate that a particular buyer will obtain.
In practice, the difference between two bank offers can remain significant for the same property transaction. Several criteria are taken into account:
In the Paris luxury real estate market, the size of the down payment alone is not always enough to distinguish between applications. A bank may also consider transferable financial assets, future savings capacity, the composition of income or the existence of other real estate assets.
Two buyers with the same income and the same down payment may therefore obtain different financing conditions depending on how their application is presented and on the institution approached.
Given the amounts typically financed in Paris, a difference of only a few tenths of a percentage point can quickly have a significant impact.
For a €1,000,000 mortgage over twenty years, excluding insurance and fees:
The difference represents approximately €303 per month, or more than €72,000 in additional monthly payments over twenty years, including around €73,000 in additional interest.
With the same monthly payment, moving from a rate of 3.21% to 3.80% reduces borrowing capacity by approximately €51,000. The mortgage rate therefore has a direct effect on the available budget, but it must be considered alongside the negotiated purchase price of the property.
A 3% price negotiation on an apartment listed at €2 million represents €60,000. In some transactions, the quality of the property negotiation can therefore have a greater financial impact than a small difference in the mortgage rate. Buyers should consequently work simultaneously on three variables: the purchase price, the financing structure and the intended holding period.
The current resilience of mortgage rate schedules does not guarantee that they will remain unchanged over the longer term.
Since December 2025, Crédit Logement has observed a gradual increase in mortgage rates, although the average rate rose only moderately to reach 3.25% in May. The composition of new lending has also changed: the share of the longest and most expensive loans has declined, which helps contain the overall average.
The European Central Bank has also pointed to a deterioration in banks' access to bond markets and anticipated tighter mortgage lending standards during the second quarter of 2026 across the euro area. It also expected demand for housing loans to decline.
If French long-term interest rates remain close to 3.80% or continue to rise, banks may eventually have to pass part of this increase on to their future mortgage rate schedules. Such a transmission would likely be gradual and vary from one institution to another.
It is also important to distinguish between a bank's official rate schedule and the rate that can actually be negotiated. Banks may increase their general rates while continuing to offer discounts to borrowers whose business they actively want to win.
The possibility of higher mortgage rates should not lead buyers to rush into purchasing a property that does not truly match their project.
In Paris, the intrinsic quality of an apartment, its floor level, natural light, layout, orientation, the condition of the condominium and the acquisition price will generally have a greater impact on its long-term value than a limited change in the mortgage rate.
Nevertheless, the current environment remains favourable for buyers who have prepared their financing in advance. Sellers are paying closer attention to the financial strength of offers and to the buyer's ability to meet the timeline required for signing the preliminary sales agreement.
Before making an offer, it is useful to obtain a banking assessment or an agreement in principle specifying:
A slightly lower offer supported by financing that has already been assessed may be preferred to a higher offer whose feasibility remains uncertain.
The interest rate offered to the buyer is not relevant only to the borrower. It also affects the overall security of the transaction.
When an offer includes a financing contingency, the seller and their real estate agent should assess the consistency between the purchase price, the announced down payment and the amount the buyer intends to borrow.
A financing condition drafted with an unrealistically low maximum interest rate may weaken the transaction if mortgage rates rise before the final application is submitted. Conversely, an unrealistic rate ceiling may reduce the buyer's protection or make it more difficult to assess a potential refusal from the bank.
In a high-end transaction, it can be appropriate to ask the buyer or their mortgage broker for documentation confirming that the financing has already been subject to an initial assessment. The objective is not to obtain a bank guarantee before signing the preliminary agreement, but to ensure that the offer is based on credible assumptions.
What is the average mortgage rate in July 2026?
The latest available national data relates to May 2026. The Banque de France reported an average rate of 3.21% for new housing loans excluding renegotiations. Crédit Logement/CSA reported an average of 3.25%, with the two organisations using different methodologies and scopes.
Why is the 10-year French government bond yield higher than mortgage rates?
Because the government bond yield is only one component of the financial environment in which banks operate. Banks also use customer deposits, regulated savings and other funding sources. In addition, an amortising mortgage does not have the same financial profile as a bond repaid at maturity.
Can the strongest applications obtain rates below the average?
Yes. National averages include very different borrower profiles, loan terms and transactions. A borrower with a high income, a substantial down payment and significant financial assets may still obtain a discount compared with the bank's general rate schedule, depending on its commercial policy.
Would higher mortgage rates automatically cause property prices in Paris to fall?
No. Mortgage rates influence borrowing capacity, but Paris property prices also depend on available supply, the quality of individual properties, the level of negotiation and the proportion of buyers with substantial down payments. The most sought-after apartments tend to be less sensitive to general changes in mortgage conditions than properties with several weaknesses.
Can you renegotiate your mortgage later?
A mortgage renegotiation or refinancing may be considered if interest rates fall sufficiently after the purchase. However, potential early repayment charges, administrative fees, guarantee costs and the remaining term of the loan must all be taken into account. A future decline in rates should therefore not be assumed when making a property purchase.
Key points to remember
"A rise in the 10-year French government bond yield does not automatically result in an immediate increase in mortgage rates. For a property purchase in Paris, the quality of the negotiation, the preparation of the financing and the strength of the buyer's application remain decisive."
