On 7 September 2026, DWS, the fund arm of Deutsche Bank, did something it had avoided for two years: it marked down the valuations of its three large open-ended real estate funds - Grundbesitz Europa, Grundbesitz Global and Fokus Deutschland - once again. For millions of savers who hold such funds through Riester pension contracts, fund savings plans, or as a supposedly crisis-proof building block of their retirement provision, this is an uncomfortable wake-up call: even seemingly solid bricks-and-mortar investments can lose value, and exactly when people least expect it.
What actually happened on 7 September
For two years, DWS had kept the valuations of its open-ended property funds largely stable, even as the commercial real estate market was quietly repricing in the background. Now the fund provider is catching up: all three funds were marked down, with unit prices losing noticeable value this year. A look at the stock exchange is particularly revealing, since fund units trade there independently of the officially stated net asset value: some units already trade at discounts of up to 27 percent versus their official fund value. In other words, the capital market had been pricing the underlying property holdings more realistically for a long time before the official fund valuation caught up.
This is not purely a DWS problem. Since mid-2023, the entire German open-ended property fund industry has seen persistent net outflows. Several smaller providers - such as Wertgrund with its Wohnselect D fund, or the Fokus Wohnen Deutschland fund - had to temporarily suspend unit redemptions altogether in 2026 because there simply was not enough liquidity available to pay out departing investors. DWS, with its multi-billion-euro funds, has remained solvent so far, but it too must respond to falling property values.
Why now, of all times
Three developments explain the timing of this correction. First, the interest rate increases of recent years have raised financing costs for commercial property and simultaneously depressed achievable sale prices - an effect that only shows up in official appraisals with a delay. Second, structural demand for office space has fallen permanently due to home working and hybrid work models, which particularly affects the classic city-centre office buildings these funds traditionally invest heavily in. Third, new regulatory requirements that took effect in April 2026 require open-ended property funds to use so-called hybrid liquidity management tools - minimum liquidity buffers and swing-pricing-like mechanisms - which force fund managers to tie their valuations more closely to actual market transactions instead of keeping them artificially stable for years.
Why this affects more people than they think
Not a bank product, even if it feels like one
The key misconception many investors make: an open-ended property fund feels like a solid savings product, but legally it is something entirely different. It is a pooled investment vehicle with a fluctuating value - not a bank deposit covered by statutory deposit protection. Anyone who instead keeps their money in a classic savings account or fixed-term deposit knows exactly, at every point in time, how much capital is available and that it is legally protected up to 100,000 euros per bank and customer. Readers looking for that kind of reliability can find transparent terms on our deposit products overview and our savings accounts comparison, without the risk of an unpleasant surprise at the next valuation round.
The notice period many only notice when they try to sell
Since a 2013 reform of German investment fund law, open-ended property funds are subject to a statutory minimum holding period of 24 months and a notice period of 12 months before units can be redeemed at the official redemption price. In practice, that means anyone who notices today that their fund is losing value cannot simply exit the next day. The only quick way out is selling on the stock exchange - and that is exactly where the discounts of up to 27 percent mentioned above show up. This illiquidity is the price of a fund being able to invest in physical buildings rather than daily-tradable securities at all. For personal financial planning, the lesson is straightforward: money that needs to stay available at short notice generally does not belong in this kind of fund structure.
Knock-on effects for the property market and mortgages
DWS's revaluations are also a signal for anyone planning to buy or finance a property themselves. When institutional appraisers value commercial real estate more realistically, banks typically also scrutinise collateral values a little more closely on private mortgage applications - which can affect the required equity share and the terms offered. At the same time, an overall more cautious approach to price discovery in the property market can also open up more room for buyers to negotiate. Anyone currently planning a property purchase should therefore compare several financing offers right now, rather than settling for their house bank's first proposal - a structured comparison via mortgage offers quickly shows just how large the differences between lenders really are.
What you should do now
Three steps make sense if you might be affected by this development. First, check your Riester contracts, fund savings plans and portfolio overviews specifically for exposure to open-ended property funds - this is often not obvious at first glance, since such funds are frequently tucked into mixed portfolios as a supposedly defensive component. Second, understand notice periods before you make an investment decision, not after. Third, for money you will need in the foreseeable future, or want to be able to rely on at any moment, use products with clear, legally protected conditions - including everyday essentials like a transparent current account without hidden fees as a solid foundation for your finances. The DWS writedown is not a reason to panic, but it is a good occasion to honestly review your own investments and check whether your return expectations still match the actual risk you are carrying.
