WASHINGTON — Tens of billions of dollars in matured U.S. savings bonds have gone unredeemed, with every month of delay costing owners real money as current 10-year Treasury yields hover near 4.79%. The figure that matters: 30 years. Series EE and Series I bonds stop earning interest exactly three decades after their issue date.
Any bond purchased in 1996 or earlier is now dead weight, still sitting in drawers and safe deposit boxes across the country while inflation quietly erodes what remains. By the numbers, the cost of inaction is steep.
Leaving a matured bond uncashed effectively gives the federal government an interest-free loan. With Treasury yields where they are, owners who delay are actively losing purchasing power they could capture elsewhere. The tax hit comes whether owners cash out or not.
Under Internal Revenue Code Section 454, accrued interest triggers a tax liability the moment a bond hits final maturity. Heirs can inherit surprise tax burdens for assets they have not even liquidated, a trap that catches families unaware.
Finding Lost Bonds Gets Harder, Then Easier
The federal government once ran an online look-up tool called Treasury Hunt. That database shut down on September 30, 2025, leaving a gap for owners trying to track forgotten holdings. New legislation changed the landscape.
The SECURE Act 2.0 now requires the U.S. Treasury to share bond data directly with state governments, making it easier to track these assets at the local level. Owners can search state-run financial databases instead.
The National Association of Unclaimed Property Administrators (NAUPA) portal allows searching for names across states where relatives have lived. The bottom line: the tool exists, but owners must know to use it.
How to Check What You Own
For physical paper bonds, the Issue Date printed on the top right corner is the critical detail. If that date is more than 30 years old, the bond needs immediate redemption. Investors will note: do not rely on the face value printed on the front.
Savings bonds were often sold at a discount, with buyers paying $25 for a $50 bond that grew over time. The actual current value can be higher or different than what the paper suggests.
The TreasuryDirect Savings Bond Calculator shows exactly what a bond is worth today. Owners input the series, denomination, and issue date to get a precise figure.
Cashing Out: The Practical Steps
Many local banks and credit unions will cash paper savings bonds for customers, though they may place limits on the dollar amount per transaction. If a local bank cannot process them, the physical bonds can be mailed to the Bureau of the Fiscal Service along with FS Form 1522. The Treasury continues to report that billions in matured, unredeemed bonds remain in circulation.
With the Treasury Hunt tool gone and tax liabilities ticking upward, the window for owners to act is narrowing. What to watch next: whether state databases under the SECURE Act 2.0 successfully reconnect significant bond holdings with their owners, and whether the Treasury develops any replacement federal search tool after the 2025 shutdown.
