Safe Deposit Box

A safe deposit box is a locked container inside a financial institution's vault that the institution rents to a customer for storing physical items. The relationship it creates is landlord and tenant rather than banker and depositor: the customer is buying secured space and the right to reach it during banking hours, and the institution has no inventory of what is inside and no obligation to make good what goes missing beyond what its rental agreement and state law impose. That distinction is the reason a box is excellent at some jobs, such as holding an irreplaceable original document, and poor at others, such as holding cash or anything that might be needed on a Sunday.

Start with what the FDIC says, because it disposes of the commonest assumption in two sentences. From its consumer guidance on boxes, safes and valuables: "A safe deposit box is not a deposit account. It is storage space provided by the bank, so the contents, including cash, checks or other valuables, are not insured by FDIC deposit insurance if damaged or stolen. Also, financial institutions generally do not insure the contents of safe deposit boxes." The first half of that follows from what deposit insurance is, and is covered on the FDIC insurance page. The second half is the part people do not expect: no coverage arrives from the bank either. The FDIC's own recommendation is to talk to a homeowner's or renter's insurance agent about adding coverage for the valuables in a box, which means the protection is bought in the insurance market rather than supplied by the vault.

The rental agreement is the operative document, and it can limit the contents. The FDIC advises reading the terms because "the bank may limit what you can keep in the box", and says expressly that those limitations could include cash. That is worth pausing on: the item most people picture in a box can be the item the contract excludes, and storing it anyway would put the customer outside the agreement while gaining no insurance. The FDIC's separate observation is the quieter cost. Money in a box earns nothing, so its purchasing power falls, which makes a box a poor place to hold currency for any length of time whatever the agreement says.

Access controls are the part that decides who is responsible when something goes wrong. The Office of the Comptroller of the Currency describes two systems banks use. Under dual control, two people, usually a bank employee and the renter, are required to open the box, so no single person can open it and remove the contents. Under authorized signature, everyone permitted to access the box signs a signature card when the box is rented, only those people are admitted, and the bank records the signature of anyone who opens it. A bank facing a claim of unauthorized access may defend itself by showing its controls were followed, and the OCC's framing of a customer's remedies is that they "generally depend on state law or the safe-deposit agreement" rather than on a federal rule.

Adding someone to the box gives them everything. The FDIC puts it plainly: a box can be jointly rented with people you would like to give unrestricted access, and "your bank would likely not be responsible for anything that people you authorize to enter the box remove without your permission." There is no partial access, no read-only version, and no audit the bank performs on your behalf, because the bank does not know what is in there. The convenience of adding an adult child so someone can reach a document in an emergency and the risk of doing so are the same fact.

A bank can open a box without the renter, and the OCC names the four situations. Dual control is recommended, or required by state law, whenever a box is opened without the renter's permission, which the OCC lists as a court order, a search warrant, rental delinquency on the box, or a branch closure. Generally at least two people must be present to inventory the contents, and the bank keeps them in the vault for safekeeping. So a drilled box does not mean lost property; it means the contents have moved into the bank's custody with a written inventory behind them.

Unpaid rent starts a clock that ends outside the bank. The OCC's answer to someone who lost track of a box rented decades earlier is that non-payment of the annual fee is itself the absence of activity: the box "likely would have been considered dormant once there was no activity, such as payment of the fee, for three to five years", with the exact period "defined by state statute." If the property then remains unclaimed and is classified as abandoned, the bank may be required to transfer the contents to the state treasurer or unclaimed-property office "in a process called escheat", and the OCC notes that some states require the bank to attempt to notify the owner first. Recovering property that has made that journey is a matter for the state's unclaimed-property office, which is the unclaimed property page's subject.

What belongs in a box turns on one question: would you ever need this when the bank is shut? The FDIC's list of good candidates is originals of key documents such as birth certificates, property deeds and car titles, US savings bonds that have not been converted into electronic securities, family keepsakes, valuable collections, photographs or video of a home's contents kept for insurance purposes, and irreplaceable photos. Its list of things to keep elsewhere is driven by access rather than by value: a passport and the original of a power of attorney are both documents someone may need urgently and outside banking hours. For an original will the FDIC declines to give a general answer and says to check with an attorney about what state law requires or recommends, which is the right posture, because the rules governing entry after death are themselves state law. As FDIC Counsel Richard Schwartz put it, those rules "restrict entry into the safe deposit box to certain individuals and permit entry only under controlled situations."

And no box is unconditional. The FDIC's own caution is that no safe deposit box or home safe is completely protected from theft, fire, flood or other loss or damage, and its practical suggestions are to place items in resealable water-safe containers and to keep no identifying information, such as the box number or the bank's name, on or near the key.

Renting a box is ordinary contracting. The customer signs a rental agreement, pays an annual fee, and receives keys or a credential; anyone else who is to have access is added to the agreement or signs the signature card at that point. Access happens during banking hours, at the branch holding the box, with the bank verifying identity and recording the entry. The bank never sees the contents. Rent is normally billed annually, often debited from an account at the same institution, and the OCC notes that banks may offer discounts on box fees to their own account holders.

A hypothetical showing the cost of using a box as a place to keep cash. Suppose Dana puts $10,000 in currency in a box and leaves it there for five years, and the box rents for $60 a year. The cash is worth exactly $10,000 at the end, because currency in a box earns nothing, and she has paid five times $60, or $300, in rent. Had the same $10,000 sat in an insured savings account earning a hypothetical 4 percent compounded annually, it would have grown to $10,000 times 1.04 to the fifth power, which is $12,166.53, so the interest alone is $2,166.53. The gap between the two choices over five years is $2,166.53 plus the $300 of rent, or $2,466.53, before considering that the account balance would have been federally insured and the currency was not. The 4 percent, the rent and the balance are all invented for the illustration; the shape of the result is not sensitive to them, and it is the FDIC's own reason for preferring a deposit account to a box for cash.

Pros

• Secured, controlled storage for physical originals that cannot be reissued, which is the job nothing else does as well.
• Entry is logged and identity-checked, and where the bank uses dual control no single person can open the box alone.
• Far harder to reach than a home safe, which the FDIC notes a burglar could more easily break into and open.
• A box opened without the renter, on a court order or for unpaid rent, is inventoried by at least two people and the contents are kept in the vault rather than disposed of.

Cons

• The contents are not covered by federal deposit insurance, and the FDIC says institutions generally do not insure them either. Protection has to be bought under a homeowner's or renter's policy.
• The rental agreement may restrict what can be stored, and the FDIC notes those restrictions can include cash.
• Nothing in a box is reachable outside banking hours or away from that branch, which rules it out for a passport or an original power of attorney.
• A joint renter has unrestricted access, and the bank would likely not be responsible for what an authorized person removes.
• Cash held in a box earns nothing and loses purchasing power the whole time.
• Stop paying the rent and the box is eventually drilled and its contents remitted to the state, on a timetable set by state statute.
• Access after the owner's death is governed by state law and is restricted to certain people under controlled conditions, so a box is a poor hiding place for the document that says who may act.
