A hurricane, tornado, flood or fire can pose a threat not just to your home, but also to those U.S. savings bonds stored in your safe or filing cabinet. But damage from a disaster — or theft or carelessness — doesn't have to extend to your bonds. You can replace them, and cash them in as well.
The U.S. Department of the Treasury has all the forms you need online, including Claim for Lost, Stolen or Destroyed United States Savings Bonds (PDF). And if you want to convert your paper savings bonds into electronic bonds, look into the Treasury Department's SmartExchange Program.
