When inflation stays elevated but you want something that doesn’t feel speculative, three government-backed and cash-equivalent tools do most of the practical work: TIPS, I Bonds, and high-yield cash alternatives. Each is designed differently, and knowing which fits your specific timeline matters more than picking a favorite.
I Bonds: Current Rate and How They Work
As of the most recent Treasury announcement, I Bonds carry a composite rate of 4.26%, good through October 2026 — made up of a 0.9% fixed rate plus an inflation-adjusted component that resets every six months based on CPI.
- Annual purchase limit: $10,000 per person per calendar year in electronic I Bonds through TreasuryDirect (plus up to $5,000 more via paper bonds bought with a tax refund).
- Minimum holding period: 12 months — you cannot redeem earlier under any circumstances.
- Early redemption penalty: If cashed before 5 years, you forfeit the last 3 months of interest. After 5 years, no penalty applies.
- Tax treatment: Interest is exempt from state and local tax, and federal tax can be deferred until redemption or final maturity (30 years).

TIPS: The Larger-Scale Alternative
Treasury Inflation-Protected Securities work on a similar principle to I Bonds — principal adjusts with CPI — but with meaningful practical differences:
- No annual purchase limit the way I Bonds have, making TIPS the more scalable option for larger allocations.
- Tradeable on the secondary market, meaning you can sell before maturity without the fixed penalty structure I Bonds impose — though you’re exposed to market price fluctuation if you sell before maturity.
- Available in a range of maturities (5, 10, and 30 years) directly from TreasuryDirect or through TIPS-focused mutual funds and ETFs.
- Federal tax is due annually on both interest payments and any inflation adjustment to principal, even though you don’t receive the principal adjustment in cash until maturity — a quirk sometimes called “phantom income” worth discussing with a CPA before buying in a taxable account.
High-Yield Cash Alternatives
For money you might need on short notice, high-yield savings accounts and money market funds have been paying in the 4%+ range through 2026 — broadly in line with or slightly above current CPI, meaning cash parked there isn’t losing much real purchasing power the way a standard checking account does.
Matching the Tool to the Timeline
| Time horizon | Best fit |
|---|---|
| Under 1 year | High-yield savings or money market fund (I Bonds aren’t accessible this early) |
| 1-5 years | I Bonds (accepting the early-redemption interest penalty if needed before 5 years) |
| 5+ years, larger amounts | TIPS, which scale beyond the $10,000 I Bond cap |
Frequently Asked Questions
Are I Bonds still worth buying at the current rate?
At a 4.26% composite rate through October 2026, I Bonds are competitive with high-yield savings accounts while also offering tax deferral and state tax exemption — reasonable for money you’re comfortable locking up for at least a year, ideally five.
What’s the real difference between TIPS and I Bonds?
The biggest practical differences are purchase limits ($10,000/year for I Bonds vs. no cap for TIPS) and liquidity (I Bonds have a fixed penalty structure; TIPS can be sold on the secondary market anytime, at whatever the current market price is).
Should I hold TIPS in a taxable account or a retirement account?
Because TIPS generate taxable “phantom income” on the inflation adjustment before you actually receive that cash, many CPAs recommend holding TIPS inside a tax-advantaged account (IRA or 401(k)) rather than a taxable brokerage account, where the annual tax bill can be a genuine cash-flow annoyance.
