Vonovia's Berlin Standoff: Mucic Pushes Back as Merz Prepares Federal Shield
Published on 09/23/2026 at 10:10 | Editorial boerse-global.de
Vonovia chief executive Luka Mucic has launched a direct counterattack against persistent calls to socialize large swaths of Berlin's housing stock, arguing that expropriation would not deliver a single additional apartment. Writing in Handelsblatt, Mucic pointed to a post-election survey of Berlin voters showing 51% reject the seizure of private landlords, with 37% in favor.
The political backdrop has shifted sharply since the Berlin Linke's election success thrust the nationalization debate back into the spotlight. Vonovia, together with its subsidiary Deutsche Wohnen, controls just over 130,000 apartments in the German capital — exposure that makes the DAX group uniquely vulnerable to the city's political mood swings.
A Federal Counterweight Takes Shape
Chancellor Friedrich Merz has pledged to move quickly on federal legislation banning the expropriation of private property, a move by the black-red coalition that now collides head-on with Berlin's state-level ambitions. The coalition committee of CDU, CSU and SPD had already agreed in early July on such a ban covering rental housing stock, with ministerial drafts currently in preparation.
Should the federal government succeed in anchoring the rule in national law swiftly and in a constitutionally sound manner, the legal foundation underpinning Berlin's socialization plans would be removed. A protracted legal battle between the city and the federal government, by contrast, would usher in a prolonged period of uncertainty. An expert commission convened by SPD and CDU concluded in 2023 that socialization could in principle be structured in a constitutionally compliant way — though critics point to a Federal Constitutional Court ruling that struck down Berlin's rent freeze on grounds the city lacked legislative competence.
Competing Price Tags Fuel the Dispute
Running parallel to the legal wrangling is a bitter argument over what socialization would actually cost. Linke politician Jan van Aken puts compensation at EUR 8 billion to EUR 12 billion, a sum he suggests could be written off over a century. Municipal officials reject that figure outright. Neukölln district mayor Martin Hikel estimates EUR 29 billion to EUR 36 billion, citing calculations by the Berlin audit office that reach as high as EUR 42 billion.
Should investors sell immediately? Or is it worth buying Vonovia?
Economists are meanwhile flagging the side effects of state intervention. Monika Schnitzer of the German Council of Economic Experts noted that the benefits of such measures would accrue mainly to sitting tenants, leaving all other market participants empty-handed. The uncertainty, she added, weighs on an investment climate in a sector already grappling with changed conditions.
Building Activity as a Counterargument
Vonovia is positioning its own construction record against the political demands. Roughly 1,000 new residential units are currently under construction in Berlin, and the company has completed 6,000 apartments there since 2013. At an average existing rent of EUR 8.26 per square meter and EUR 10.80 for new lettings, the portfolio offers an affordable base in a market that remains tight.
Operational progress extends beyond the political hotspots. In Hamburg-Lurup, the group completed a serial facade renovation of a 1960s apartment block in two weeks per building. At EUR 4 million, investment costs came in around 20% below earlier pilot projects, while energy efficiency improved from class E to B. If such methods prove scalable, Vonovia gains considerable room for energetic refurbishment while the core business delivers steady returns.
Market Signals Point in Different Directions
Despite the political noise, not all market observers are pessimistic. Berenberg continues to rate the stock a buy, even as Goldman Sachs has already dropped its recommendation. The shares closed yesterday at EUR 17.57, hovering just above their 52-week low of EUR 17.05, and today trade at EUR 17.48 — down 29% since the start of the year.
The changed interest rate environment adds further pressure. Ten-year German government bonds yield 3.47%, structurally raising refinancing costs for residential property groups. Should municipal new-build projects increasingly stall on local resistance, organic growth would be dampened further.
The Cabinet Timetable Is the Next Catalyst
For the stock's near-term direction, defending the recent lows is essential. As long as the shares hold above EUR 17.05, the chance of stabilization remains intact; a break below that level under renewed political pressure would threaten an extension of this year's losses. The decisive catalyst is the federal government's concrete draft law against housing expropriation. Once ministries present the proposal and the cabinet signs off, investors will finally learn how effectively Berlin's plans can be countered from the federal level. Until that signal arrives, Vonovia's stock remains tethered to the political rhythm in Berlin — and in Berlin-Mitte.
