Morgan Stanley analysts reiterated a cautious view on Paris office stocks, stating that the sector is contending with countervailing forces that could limit near-term upside for landlords and listed office companies.
The firm said an expected rise in inflation driven by higher oil prices in 2026 should feed through to stronger rent indexation in 2027 and 2028, providing an earnings tailwind for office landlords that use inflation-linked lease mechanisms. However, this prospective benefit is likely to be offset by weaker macroeconomic growth, which Morgan Stanley expects will contribute to higher vacancy rates across Paris office markets.
Analysts warned of negative reversion pressures as the gap widens between passing rents - those set by inflation-linked indices - and market rents, which are determined by prevailing supply and demand. That divergence, the note said, presents a valuation risk because contractual income tied to indexation may not reflect current market clearing rents when tenants renegotiate or leases roll.
The brokerage described the outlook for Paris offices as uncertain. Take-up has remained persistently low while new supply sits at record highs, the analysts said. Capital values for office assets continue to fall and transactions remain limited, reflecting both price discovery challenges and constrained investment appetite. The firm observed that assets in central Paris have shown relatively greater resilience, while unconfirmed press reports suggest notable value declines for several properties being sold in La Defense.
On financing, Morgan Stanley noted that most continental European office companies have deployed hedging to shield their in-place debt costs from higher market rates. As a result, average in-place cost of debt remains below 2% for many firms. Nevertheless, the bank is now modelling a modestly higher path for financing costs, forecasting a 2 basis point annual increase in average debt costs relative to its prior assumptions, driven by elevated marginal financing rates.
The analysts also flagged disruption risk from artificial intelligence. While the scope and timing are uncertain, Morgan Stanley suggested that AI-driven efficiencies could influence employment patterns and, by extension, corporate demand for office space, creating an additional source of uncertainty for the sector.
Despite the cautious stance on French offices overall, Morgan Stanley retains a constructive view on select names within the subsector. The firm has an Overweight rating on Inmobiliaria Colonial - referenced as Colonial - citing expectations that the company will deliver the strongest earnings per share growth among its French office peers.
Bottom line: The Paris office market faces an interplay of supportive inflation-linked rent dynamics and deteriorating demand fundamentals, with rising vacancy, negative rent reversion and financing pressures combining to produce an uncertain outlook for capital values and transactions.
