Why Treasuries Beat High-Yield Savings (HYSA)

A 5% return at a bank is NOT the same as a 5% return from Uncle Sam. The tax exemption makes Treasuries the clear winner for high earners.

How to Use TreasuryDirect.gov

Warning: Do not use the “Back” button on your browser, or the site will log you out. It is very sensitive.

Step 1: Open an Account

Go to the site and select “Open a New Account.” You will need your SSN, Driver’s License, and Bank Routing Number.
Note: If the system cannot verify you automatically, you may have to mail a physical paper form stamped by a bank. (Yes, really).

Step 2: BuyDirect Tab

Once logged in, click the “BuyDirect” tab at the top. Select the type of security:

  • Bills (T-Bills): Short term (4, 8, 13, 26, 52 weeks). Sold at a discount (e.g., pay $990, get $1,000).
  • Notes/Bonds: Longer term (2 – 30 years). Pays interest every 6 months.
  • Series I Bonds: Inflation-protected savings bonds. (Limit $10k/year).

Step 3: The Auction Process

You don’t buy instantly like a stock. You place an order for the next auction. The price/rate is determined on auction day, and the money is withdrawn from your bank shortly after.

What Should You Buy?

1. T-Bills (The Cash Park)

Use this for money you need in 1-6 months. It pays the current high interest rate and is very liquid. If you buy 4-week bills, you can set them to “auto-reinvest” to create a passive income ladder.

2. Series I Bonds (The Inflation Shield)

These are special. The interest rate has two parts: a fixed rate + an inflation rate. They are designed so your money never loses purchasing power.
Rule: You must hold them for at least 1 year. If you sell before 5 years, you lose the last 3 months of interest.

Pro Tip: The “T-Bill Ladder”

Don’t just buy one big bond. Build a ladder.
Buy 4-Week T-Bills every week for 4 weeks.
Result: Every Tuesday, one bill matures and cash hits your account. If you don’t need it, the “Auto-Reinvest” feature rolls it into a new one. It’s a perpetual high-yield machine.

Frequently Asked Questions

Can I buy these at Fidelity/Vanguard?
Yes, mostly. You can buy T-Bills, Notes, and Bonds at most brokerages (often easier to sell there). However, Series I Bonds can ONLY be purchased on TreasuryDirect.gov.
What if I need the money early?
On TreasuryDirect, you have to transfer the bond to a bank to sell it (painful). If you think you might need to sell early, buy T-Bills through a brokerage (Fidelity/Schwab) where you can sell them instantly on the secondary market.
