European Office Real Estate Posts Cautious Q1 2026 as Leasing Volumes Decline and Investors Pause

European office real estate got off to a subdued start in 2026, with leasing activity across 18 major markets declining 16% in the first quarter and total take-up reaching 1.67 million square meters — significantly below the five-year average — according to a market commentary published May 19, 2026, by BNP Paribas Real Estate.

The report attributes the contraction primarily to a drop in large transactions above 5,000 square meters, as occupiers navigated an uncertain economic and financial environment by gravitating toward smaller footprints and higher-quality buildings.

Leasing Activity Falls Across Most Major Markets

Take-up declined in two of Europe's largest office markets: Paris fell 23% and London dropped 15% year-on-year. The six main German markets collectively posted a 12% decrease, though results varied by city. Munich was a notable outlier, recording 172,000 square meters of take-up in Q1 2026 — a 26% year-on-year increase and the market's highest quarterly figure since 2022 — driven in part by three transactions exceeding 20,000 square meters each. Berlin also outperformed, with 146,000 square meters transacted, up 42% year-on-year.

Elsewhere, results were mixed. Milan and Madrid recorded significant declines of 36% and 25%, respectively. By contrast, Barcelona (+34%), Dublin (+21%), Rome (+11%), and Brussels (+11%) all posted growth, underscoring what BNP Paribas Real Estate described as a heterogeneous recovery across the continent.

Vacancy Rises as Market Polarization Deepens

Office supply continued to expand across Europe, albeit unevenly. The average vacancy rate reached 9.5% at the end of March 2026, up 30 basis points year-on-year, despite limited new deliveries. BNP Paribas Real Estate noted that this figure masks significant geographic disparities.

Central business districts maintained tighter conditions, with an average vacancy rate of 5.6%, compared with 11.2% in secondary markets. The firm said the widening gap reflects increasing market polarization and confirms occupiers' preference for central locations with strong transport accessibility, while vacancy rates climb more sharply in peripheral areas and older building stock.

Prime Rents Rise, Supported by Limited Availability of New Space

Prime office rents continued to increase across most major European cities, supported by the limited availability of new space in central locations. Southern European markets led rental growth, with Barcelona recording a 10% increase, Madrid and Milan each rising 7%, and Rome up 4.5%. Over a 12-month period, London posted a notable 6% increase.

However, BNP Paribas Real Estate cautioned that Q1 2026 data suggests rental growth may begin to moderate in several markets. The firm noted that some occupiers, faced with elevated prime rents, are increasingly considering secondary locations that offer both accessibility and quality — a trend that could ease upward pressure on prime rents going forward.

Investment Volumes Decline in Q1 but Rise on a Rolling Basis

On the investment side, more than €36 billion was deployed across European real estate in Q1 2026, representing a limited year-on-year decrease of 7%. On a rolling 12-month basis, volumes are up 10%, consistent with momentum observed at the end of 2025. BNP Paribas Real Estate characterized the Q1 slowdown as a pause rather than a market downturn.

The office sector reflected the broader trend, with investment volumes declining 13% to approximately €9 billion in the quarter. The firm attributed the moderation to a normalization following a strong close to 2025, as well as varied performance across markets. Amsterdam and Madrid showed relative resilience, maintaining solid activity levels.

Country-level dynamics diverged sharply. France recorded a sharp decline of 42% following a strong 2025, though Paris remained a concentration point for transactions. The United Kingdom saw a more moderate correction of 15%, with London retaining its position as Europe's leading investment market. Germany stood out positively, with investment volumes rising 5%, supported by improved market sentiment.

Peripheral markets gained momentum. The Netherlands posted a 166% increase in investment volumes, while Spain attracted more than €1 billion — a fivefold increase year-on-year. Ireland also confirmed a recovery trajectory, according to the report.

Yields Remain Broadly Stable Amid Financial Uncertainty

Real estate yields held broadly stable in Q1 2026, though BNP Paribas Real Estate noted signs of slight upward pressure in select markets, including Paris at 4.25% and Berlin at 4.35%. The firm said central banks are operating in an increasingly uncertain environment, with renewed inflationary pressures tied to geopolitical tensions raising the prospect of further interest rate adjustments.

"Markets have already largely priced in adjustments in valuations in a context of tighter financing conditions. While current uncertainties may still trigger temporary fluctuations in yields, these adjustments should remain limited in both scale and duration," said Etienne Prongué, Head of International Investment Group (IIG) at BNP Paribas Real Estate.

The firm added that increased investor selectivity continues to shape the market, with a clear preference for core assets in the most liquid markets. Prime rental growth was cited as a supporting factor that helps offset the potential impact of further yield adjustments.

Outlook: Selective Demand, Structural Divergence

BNP Paribas Real Estate described the broader European real estate market as resilient but in a phase of cautious observation, shaped by macroeconomic uncertainty, downward revisions to European growth forecasts, and the potential re-emergence of inflationary pressures linked to energy markets. The firm noted that market fundamentals remain solid and that demand for high-quality assets continues to support activity, even as occupiers and investors adopt more selective approaches in the near term.
