Safe deposit box insurance is a specialty policy that covers what you store in a bank box, because the bank does not insure the contents and the FDIC does not cover them, and one provider says its cover starts as low as $25 a year. The catch is the assumption gap: a SurveyUSA analysis reported in a consumer article found about half of box holders believe a bank or government agency insures their box, and standard homeowners policies give only limited cover for items kept outside the home.
Key Takeaways
- The contents of a safe deposit box are not FDIC insured, and banks typically carry only a liability policy that protects themselves if found negligent
- About 25 million safe deposit boxes are leased in the US, and roughly half of holders wrongly believe the contents are insured
- Specialist cover through Safe Deposit Box Insurance Coverage (SDBIC) advertises limits from $5,000 to $500,000, from $25 a year, with no deductible
- Standard homeowners policies generally provide only limited cover for items stored outside the home and rarely cover flood
- In the 2015 Hatton Garden heist in London, over 70 boxes were ransacked and many owners had not insured the contents
What Is Safe Deposit Box Insurance?
InsuranceNewsNet reports that after a fire at a Citibank branch in Manhattan, box holders learned the bank’s lease said it does not carry insurance on the contents of the box, and that the FDIC, which insures deposit accounts, does not cover safe deposit boxes. SDBIC-style policies, offered through banks and brokers such as McGriff, cover property in the box including gold, cash, collectibles, legal documents, photos and electronic backup devices, and McGriff says no disclosure or appraisal of contents is required at sign-up. A Texas bank, ANBTX, tells customers the contents are not FDIC insured and offers the cover through SDBIC.
Does Homeowners Insurance Cover a Safe Deposit Box?
Only partly. Bottom Line says homeowner’s insurance generally provides limited coverage for items stored outside the home and rarely covers flood damage, and suggests asking how much a rider costs or buying a specialized policy that includes flood. InsuranceNewsNet adds that a standard homeowners policy provides no cover for bullion coins stored in a box, and that flood is the most common peril threatening safe deposit boxes. The Christian Science Monitor quoted an agent who noted most policies fail to mention safe deposit boxes, which could cause a dispute after a loss.
| Source of Protection | What It Does | Key Catch |
|---|---|---|
| The bank | Carries liability insurance for its own negligence | Does not insure box contents |
| FDIC | Insures deposit accounts | Does not cover box contents |
| Homeowners policy or floater | Limited off-premises cover | Rarely covers flood; box may not be named |
| Specialist box policy | Covers contents up to a chosen limit | Terms and exclusions vary |
How Much Does Safe Deposit Box Insurance Cost?
McGriff says SDBIC coverage starts as low as $25 a year, with limits from $5,000 to $500,000 or higher chosen by the holder. ANBTX says the cost depends on the limit you select, and that the premium plus the cost of appraising stored items is almost always higher than the cost of the box policy alone, which is an argument for a box policy over a scheduled homeowners rider. American Insurance Point told a Florida station rates are lower when contents sit in a bank box. The sources reviewed do not give a premium for specific limits, so ask for a quote at your chosen limit. Several sources are sellers, so treat the prices as marketing starting points.
What Happened in the Hatton Garden Heist?
A Mondaq legal analysis says burglars disguised as workmen entered the Hatton Garden Safe Deposit building in London over the Easter weekend of 2015, descended a lift shaft and drilled through a 2 metre thick vault door, ransacking over 70 boxes. Many owners had chosen not to insure the contents, and many valuables were not documented as stored there, which complicated claims. The article notes uninsured owners might pursue civil actions in the courts, though recovery is uncertain.
How Do Box Contents Get Lost?
Bottom Line says losses are not uncommon, especially because of banking errors as banks consolidate boxes into fewer branches, plus missed rent payments, fires and floods, and one insurer estimates 33,000 boxes a year suffer some damage or loss. It tells the story of a Florida woman whose Chase box was reassigned to another customer after 2016. ClickOrlando reports an expert investigating 17 cases involving lost bank box contents that were never insured, and quotes the woman as saying the bank told her to go to her own insurer.
What Should You Check Before Buying?
- Named property: confirm the policy names safe deposit box contents explicitly
- Flood: check flood cover, since the most common peril is often excluded
- Limit: choose a limit that matches what is inside
- Records: photographs and appraisals help prove what you stored
- Annual check: Bottom Line suggests checking the box at least once a year
How Does This Connect to Other Valuables Cover?
