If you’re worried about runaway inflation eating away at your hard-earned cash, you’re not alone. The stock market might spike your anxiety, but there’s a pair of boring investments that quietly protect your savings: Treasury I-bonds and Treasury Inflation-Protected Securities (TIPS). While they may not trend on social media, these government-backed securities are designed to beat inflation and keep your money safe. Let’s break down what makes them an intelligent pick for building long-term, inflation-resistant wealth—even if you prefer a set-it-and-forget-it approach.
Key Takeaways: Why Consider I-Bonds and TIPS?
Inflation protection: Both adjust your returns based on the Consumer Price Index (CPI), keeping purchasing power steady.
Government guaranteed: U.S. Treasuries are backed by the “full faith and credit” of the U.S. government—possibly the world’s safest investment.
Simple and low-cost: No fancy strategies required. Buy, hold, and let the Treasury do the hard work.
I-bond rates (as of mid-2024): Composite rate is 4.28% (6-month annualized), partially tax-deferred.
TIPS yields (summer 2024): Real yields around 2% PLUS inflation adjustment, taxable but available in retirement accounts.
Low minimums: Start with $25 for TIPS and $25 for I-bonds via TreasuryDirect.
Understanding Inflation: Why It Threatens Your Savings
Every year, the price of groceries, gas, and just about everything else creeps upward. In 2022, U.S. inflation peaked at over 9%. Even now, it hovers above the Federal Reserve’s 2% long-term target. If your cash is stashed in a checking account paying 0.40%, your real purchasing power shrinks. Over ten years, a 3% inflation rate cuts your money’s value by nearly 26%!
This is why putting your ‘safe’ cash to work in investments designed to outpace inflation is so critical. Treasury I-bonds and TIPS offer a simple, low-risk solution that regular savings accounts and CDs just can’t match.
What Are Treasury I-Bonds?
Treasury I-bonds are U.S. savings bonds designed for small investors who want inflation protection. They’re issued directly by the U.S. Treasury and combine a fixed rate with a variable inflation rate (updated every May and November).
How I-Bonds Work
Composite rate: The earnings rate is a combination of a fixed rate (currently 0.20% as of July 2024) and a variable inflation rate (currently 4.08% annualized).
Interest accrues monthly: Compounded semiannually, paid at redemption.
Minimum purchase: $25 (electronic), $50 (paper via tax refund).
Purchase limit: $10,000 per person per year (extra $5,000 via tax refund).
Your principal is guaranteed—you can’t lose money, even if inflation rates drop.
Who Should Buy I-Bonds?
I-bonds are ideal if you want:
Inflation-proof savings for the next 1–30 years (minimum hold is one year, penalty if redeemed in less than five).
Tax-advantaged interest (tax-free at the state/local level; defer federal tax until redemption or maturity).
A simple way to grow your emergency fund above inflation.
You can purchase I-bonds online via Acorns for micro-investing options, or directly from the Treasury at TreasuryDirect.gov.
What Are TIPS (Treasury Inflation-Protected Securities)?
TIPS are marketable U.S. government bonds whose par value adjusts based on inflation, measured by CPI. Unlike I-bonds, TIPS can be bought and sold on secondary markets and held in IRAs or brokerage accounts.
How TIPS Work
Interest rate: Fixed at auction (e.g., 1.80%) PLUS inflation adjustment. Your principal increases if inflation rises, so your interest payments also grow.
Terms: 5, 10, or 30 years; $100 minimum investment.
Can be sold anytime: Prices fluctuate, so there’s interest rate risk if you don’t hold to maturity.
Marketplace access: Buy through the U.S. Treasury, or via a brokerage like Robinhood for added convenience.
Who Are TIPS For?
TIPS make sense for anyone seeking:
Serious inflation hedging with larger sums ($100+ per purchase)
The ability to buy/sell easily (secondary market liquidity)
Tax-advantaged retirement accounts (hold TIPS in IRAs or 401(k)s for tax efficiency)
Many robo-advisors like Betterment or M1 Finance automatically include TIPS in portfolios to help defend against inflation.

How to Buy I-Bonds and TIPS: Step-by-Step Guide
Buying I-Bonds Directly
Go to the U.S. Treasury’s secure site, TreasuryDirect.gov, and set up a free account (takes about 20 minutes).
Connect your bank account by verifying two small test deposits.
Choose “BuyDirect” and select Series I Savings Bonds. Start with as little as $25.
For paper I-bonds, use your federal tax refund (up to $5,000 per year).
For a hands-off approach, apps like Acorns can help automate your investments in diversified portfolios, although you can't buy I-bonds directly in Acorns; you'll access inflation-fighting assets broadly.
Buying TIPS (Several Ways)
Buy at auction or on the secondary market at major brokerages like Robinhood or M1 Finance. Minimums are typically $100.
Select TIPS mutual funds or ETFs, such as the iShares TIPS Bond ETF (TIP) or Schwab U.S. TIPS ETF (SCHP), which pool your money with others for diversification and easy trading.
Hold TIPS in IRAs, 401(k)s, or taxable accounts. Many robo-advisors automatically add them for inflation protection.
You may want to track your asset allocation and performance for free using a tool like Personal Capital.
Real-World Returns: How I-Bonds and TIPS Have Fought Inflation
Recent Rate Example
May–October 2024 I-bonds: 4.28% annualized rate (based on a fixed rate of 0.20% and 2.04% semiannual inflation).
TIPS 10-year bonds (July 2024): Real yields around 2.20% PLUS actual CPI inflation (currently ~3.3%). That’s a 5.5%+ total yield if inflation stays elevated.
In the 2000s, I-bonds issued at a 3.4% fixed rate (still compounding!) now have outperformed nearly all 'safe' bank products. And TIPS issued then have seen their principal adjust upward dramatically in years with high inflation.
When Do These Bonds Not Make Sense?
If inflation is persistently low/negative, fixed-rate CDs may pay better (rare in the 2020s climate).
If you need absolute liquidity, a savings account is more flexible than I-bonds.
If tax deferral isn’t important to you, TIPS in taxable accounts produce ‘phantom income’ since you pay taxes on inflation adjustments as they accrue.
Pros and Cons: Are “Boring” Bonds Right For You?
Advantages
Safety: U.S. government guarantee.
Inflation defense: Your savings keep pace with rising prices.
Low minimums: You don’t need to be wealthy—anyone can buy.
Flexibility: TIPS are tradable; I-bonds defer federal tax.
Drawbacks
Annual purchase limits: You can only buy up to $10K/year in I-bonds per SSN.
Penalty for early redemptions (I-bonds): Forfeit 3 months’ interest if cashed in within 5 years.
Tax complexity (TIPS): Pay taxes yearly on inflation increases, even if you don’t sell.
Building a Diversified Inflation-Proof Portfolio
Suggested Allocation Strategies
Max your I-bond allowance each year for ultra-safe, inflation-proof savings (emergency fund or bond ladder).
Complement I-bonds with TIPS funds in your retirement accounts—great for 401(k)s or IRAs.
Pair with Fundrise or Acorns for exposure to real estate or diversified equities—assets that may also hedge inflation but carry more risk.
Keep some liquid cash for day-to-day needs, but don’t let your long-term money rot in a checking account.
Other ‘Inflation-Proof’ Ideas (with Higher Risk)
Real estate (rents often rise with inflation—invest using Fundrise)
Stock and REIT funds (long-run winners but can be volatile)
Gold or commodities (hedge against inflation but don’t produce income)
Side hustles and digital assets—grow your income with platforms like Fiverr or build a business on Shopify
Use your risk tolerance and time horizon to decide how much to allocate to each.
Practical Tips for Getting the Most From Inflation-Protected Bonds
Buy I-bonds early in the month to lock in a full month’s interest with your purchase date.
For TIPS, consider buying when real yields are higher (above 1% is typically a good entry).
Reinvest TIPS proceeds into new issues if you prefer simplicity and want to keep pace with changing rates.
Track all your accounts (including I-bonds, TIPS, ETFs) with Personal Capital so you never lose sight of your true asset allocation.
Avoid buying TIPS in taxable accounts unless you’re ready to track “phantom” taxable income each year.
Final Thoughts: Are I-Bonds and TIPS Right for You?
To sum it up: Inflation is unpredictable, but your investment plan doesn’t have to be. Treasury I-bonds and TIPS are unexciting on the surface—but their quiet power is in preserving your purchasing power for years or even decades. Start building your truly “safe” portfolio by adding a dose of inflation protection today—your future self will thank you when your savings survive whatever the economy throws your way!
If you’re ready to get started, open an account with Robinhood, M1 Finance, or Acorns to easily diversify your investments (including tips and bonds), or go straight to TreasuryDirect for I-bonds. And make inflation work for you—not against you.
