Interest Rates 2026: Impact on Luxury Purchases
After a first rise in three years and a French OAT that has just crossed 4%, the question of credit is back on the table — even for a segment where bank financing plays a different role than the rest of the market.
An update on the mortgage lending situation
After a year of stability between June 2025 and June 2026, the European Central Bank surprised markets by raising its key interest rates by 0.25 percentage points in June 2026—its first increase in three years. It then opted for a pause at its meeting on July 23, providing banks with a window of opportunity. As a result, mortgage rates remained broadly stable in August, but vigilance is still advised for the fall.

The 4% OAT, the real signal to watch
Beyond the ECB's decisions alone, it is the French 10-year OAT—the rate at which the government borrows on the markets—that is now attracting the attention of banks. This rate has just crossed the symbolic threshold of 4%, a level which, if it remains stable, could gradually put pressure on bank lending rates in the coming months.

Why doesn't the luxury sector react like the rest of the market?
In the ultra-luxury segment, a significant proportion of transactions are carried out without recourse to traditional bank credit, which mechanically reduces the direct sensitivity of this market to interest rate variations.
The usury rate for the 3rd quarter of 2026 has been raised to 5.29% for 20 years and more — a development which paradoxically facilitates access to credit for the most constrained cases, including some complex wealth management arrangements.
Foreign buyers, often structured through international financing or holding companies, do not necessarily depend on French bank rates observed in the domestic market.
Even without recourse to credit, rising rates influence the general market sentiment and can strengthen the bargaining position of buyers on less exceptional or less sought-after properties.
Of note: the August increase affected high-income earners (over €120,000 annually) more than those with more modest incomes—up to +0.15 percentage points over 25 years, compared to near stability for more typical incomes over shorter terms. This paradox is something that buyers who still opt for traditional bank financing should be aware of.
Should we accelerate or wait for a prestigious project?
For a buyer using financing, the relative stability observed in August 2026 represents a window of opportunity before a possible change in interest rates in the fall, if the French government bond (OAT) remains above 4%. Industry experts generally recommend finalizing financing arrangements before September rather than waiting for clarification that could be delayed.
For a cash buyer, the question is different: interest rate fluctuations primarily influence the market's psychological climate and the behavior of other market participants, rather than their own financial capacity. In both cases, a precise simulation with a broker or financial advisor remains the best way to objectively assess your strategy before making any commitment.
