Safe Deposit Box Insurance 2026: What the Latest Stiftung Warentest Comparison Shows

A safe deposit box is widely seen as one of the safest places to store valuables - gold, jewelry, important documents, cash. But what happens if something goes wrong anyway? That's exactly what the latest comparison by Stiftung Warentest (Finanztest 8/2026) set out to answer, examining 43 safe deposit box providers on, among other things, how well the contents are insured. The result: there are sometimes enormous differences in price and insurance coverage - and without their own safe deposit box insurance, many renters are relying on more protection than they actually have.

Why this topic is so relevant right now

The trigger for the new test was a break-in at a savings bank branch in Gelsenkirchen-Buer over the 2025 Christmas holidays: criminals broke open almost all of the roughly 3,250 safe deposit boxes there, with an estimated damage of 30 million euros. Cases like this - and similar ones before it - raise an uncomfortable question: does the bank actually cover the contents of my safe deposit box?

The answer is sobering. A provider is only liable without limit if it can be proven at fault - for example, because it failed to adequately secure its vault. Whether that's the case in an individual instance is often settled only after years of litigation.

Why bank liability alone isn't enough

A recent ruling by the Hanseatic Higher Regional Court (OLG) Hamburg shows just how bank-friendly such proceedings can turn out: five years after a break-in at a savings bank branch in Norderstedt, the court ruled that Hamburger Sparkasse owes those affected no compensation beyond the 40,000 euros already paid (case no. 13 U 95/23) - contradicting an earlier, more customer-friendly ruling.

Attorney Daniel Kuhlmann, who represents around 650 victims of the Gelsenkirchen case, calls the ruling "extremely bank-friendly" in his interview with Stiftung Warentest, warning that it effectively lowers the bar for banks' duty of care. His advice: anyone storing valuables should not rely solely on the bank's liability, but should additionally take out their own, adequately high insurance. In the event of a claim, it typically settles far faster and with far less hassle than a years-long legal dispute.

What the Stiftung Warentest comparison reveals about insurance

Looking across all 43 providers tested reveals significant gaps in the market:

• Only 31 of 43 providers include any insurance at all in the rental price.
• 35 providers allow the insured sum to be topped up afterwards.
• 12 providers offer no insurance coverage whatsoever in the rental price - seven of them have dropped it since the last study.
• The insured sum included in the rental price ranges from 2,500 to 50,000 euros, depending on the provider.
• Anyone booking additional coverage sometimes pays noticeably more than before: Deutsche Bank, for instance, raised its price per 1,000 euros of insured sum from 0.57 euros to 0.86 euros. Sparkasse Saarbrücken, Schließbar23 and VR Bank in Holstein have also raised their prices.

The message is clear: anyone renting a safe deposit box should scrutinize the insurance coverage just as closely as the rental price itself - and should not simply assume the contents will be replaced in the event of a claim.

Cash in the safe deposit box: the most common insurance trap

Cash may generally be stored in a safe deposit box - but it's far from insured everywhere. According to the current test, 14 of 43 providers explicitly exclude cash from their insurance, and three more only cover it for an extra fee. Anyone storing larger amounts of cash should clarify this explicitly before signing a contract.

On top of that, in the event of a claim, renters must prove what was actually in the box - which is especially difficult for cash, since it carries no individually identifiable features. All the more reason to choose an insured sum that realistically matches the value stored from the outset, rather than having to argue about proof requirements after the fact.

Safe deposit box insurance at Trisor: how you're protected

At Trisor, insurance coverage is part of the offering from day one - not an afterthought buried in paperwork:

• A base coverage of 5,000 euros is automatically included in every plan's rental price - no separate application needed.
• Coverage can be increased up to 500,000 euros (Standard, Premium, Business Standard and Business Premium plans; up to 30,000 euros on the Basic plan).
• Maximally flexible, never rigid: the insured sum can be adjusted personally at any time - in small increments, upwards or downwards, independent of the safe deposit box size or contract term. Adding new valuables? Simply top up the sum. Taking items out? Just as easily reduce it again. There's no new contract commitment and no waiting period either way.
• Coverage includes burglary, robbery, vandalism, fire and water damage, among other risks - and cash is covered too, which, according to the Stiftung Warentest comparison, is not the case for roughly a third of providers in the market.
• Coverage is underwritten by a consortium of well-known insurers, including AXA and HDI.
• The premium is calculated transparently: 0.15% per year of the chosen insured sum plus insurance tax - for example, around 6.70 euros per month for 50,000 euros of additional coverage.

This directly addresses the weak points the current Stiftung Warentest comparison identifies as the biggest gaps in the market: missing or recently discontinued insurance coverage, excluded cash, and inflexible top-up options.

Conclusion

The 2026 Stiftung Warentest comparison makes one thing clear: a safe deposit box is only as safe as its insurance. Anyone relying solely on bank liability is taking on considerable risk in light of recent court rulings. What matters is a safe deposit box with insurance built in from the start that also covers cash and can be flexibly adjusted to the actual value of its contents at any time - up or down.
