Side-by-Side Comparison

Treasury Bonds (T-Bills, Notes, Bonds)

Pros

+Backed by the full faith and credit of the US government — safest investment on earth
+State and local tax exempt — huge advantage in high-tax states like NY, CA
+Highly liquid — massive secondary market, sell anytime
+No early withdrawal penalty — sell on secondary market (may gain or lose value)
+Competitive yields, especially for T-bills (under 1 year)

Cons

-Interest rate risk if selling before maturity — bond prices fall when rates rise
-Slightly more complex to purchase than a CD (though TreasuryDirect makes it easy)
-Returns are modest — you won't get rich on Treasury yields
-Long-term bonds can lose significant value in rising rate environments

Best For

Investors in high-tax states, safety-first savers, people who want government-backed certainty, and anyone building a bond ladder.

Certificates of Deposit (CDs)

Pros

+Simple — walk into your bank or open one online in minutes
+FDIC insured up to $250,000 per depositor per bank
+Guaranteed rate for the full term — no interest rate risk if held to maturity
+Some banks offer no-penalty CDs with early withdrawal flexibility
+Promotional rates from online banks can beat Treasury yields

Cons

-Early withdrawal penalties on most CDs (typically 3-12 months of interest)
-Fully taxable at federal AND state level — worse than Treasuries in high-tax states
-FDIC insurance is per bank — need to spread across banks for amounts over $250K
-Rate shopping is annoying — each bank has different terms and fine print

Best For

Savers who want dead-simple guaranteed returns, people in low-tax or no-tax states, and anyone who likes the FDIC guarantee.

Glen's Verdict

Former hedge fund manager, current index fund enthusiast

If you live in a state with income tax (which is most of you), Treasuries win on an after-tax basis because they're exempt from state and local taxes. A 5% Treasury yield in New York is effectively 5.5%+ compared to a 5% CD that gets taxed at state level too. If you live in Texas, Florida, or another no-income-tax state? It's a wash — go with whichever has the higher yield. I use short-term T-bills for cash I won't need for 3-12 months and HYSA for my emergency fund. The TreasuryDirect website looks like it was designed in 2003, but the product itself is great.
