Government Bond
Quick Definition
A government bond is a debt security issued by a national government to raise money for public spending. In exchange for lending money to the government, investors receive regular interest payments (coupons) and the return of their principal at maturity. U.S. government bonds, called Treasuries, are considered the world's safest investment, backed by the full faith and credit of the United States.
What It Means
When governments spend more than they collect in taxes, they borrow the difference by issuing bonds. Investors who buy these bonds become creditors of the government, earning a fixed return over a set period. As of July 2026, the U.S. national debt stands at approximately $39.5 trillion, with the Treasury issuing trillions in new securities each quarter to refinance maturing debt and fund ongoing deficits.
Government bonds serve two roles in the financial system. First, they provide portfolio safety: in times of crisis, investors flee to government bonds as a safe harbor. Second, they act as a global pricing benchmark: U.S. Treasury yields are the "risk-free rate" against which all other investments are priced.
Every other interest rate in the economy, from mortgages to corporate bonds to auto loans, is priced as a spread above Treasury yields. This makes Treasury yields the foundation of the entire interest rate structure. When the 10-year Treasury yield moves, the cost of capital across the entire economy shifts with it.
U.S. Treasury Securities: The Benchmark
The U.S. Treasury issues several types of securities:
| Security | Maturity | Interest | Minimum | Notes |
|---|---|---|---|---|
| T-Bills (Treasury Bills) | 4 weeks to 52 weeks | None (issued at discount) | $100 | No coupon; profit = face - purchase price |
| T-Notes (Treasury Notes) | 2, 3, 5, 7, 10 years | Semi-annual coupon | $100 | Most commonly referenced; 10-year is benchmark |
| T-Bonds (Treasury Bonds) | 20 or 30 years | Semi-annual coupon | $100 | Longest duration; most rate-sensitive |
| TIPS (Treasury Inflation-Protected Securities) | 5, 10, 30 years | Semi-annual + inflation adjustment | $100 | Principal adjusts with CPI |
| I-Bonds (Series I Savings Bonds) | Up to 30 years | Inflation-adjusted | $25 | Purchased directly; $10K/year limit per person |
| FRNs (Floating Rate Notes) | 2 years | Quarterly variable | $100 | Rate tied to highest accepted discount rate |
Current U.S. Treasury Yield Curve (July 2026)
The Federal Reserve has held the federal funds target range at 3.50% to 3.75% since early 2026. The yield curve is upward-sloping, with longer maturities offering higher yields:
| Maturity | Yield (July 23, 2026) |
|---|---|
| 3-month T-Bill | 3.95% |
| 1-year T-Note | 4.15% |
| 2-year T-Note | 4.37% |
| 5-year T-Note | 4.46% |
| 7-year T-Note | 4.58% |
| 10-year T-Note | 4.71% |
| 20-year T-Bond | 5.20% |
| 30-year T-Bond | 5.17% |

The June 2026 CPI report showed headline inflation easing to 3.5% year over year, with core CPI at 2.6%. The Federal Reserve voted unanimously at its June 2026 FOMC meeting to hold rates steady, citing tariffs, supply-chain disruption, and AI-related investment as forces keeping inflation above the 2% target.
Government Bonds Around the World
| Country | Bond Name | Creditworthiness | Notes |
|---|---|---|---|
| United States | Treasuries | AA+ (S&P) | Global reserve currency; safest benchmark |
| Germany | Bunds | AAA | European benchmark; often lower yield than U.S. |
| United Kingdom | Gilts | AA | Long history of issuance |
| Japan | JGBs (Japanese Government Bonds) | A+ | World's highest debt-to-GDP ratio (~250%) |
| France | OATs | AA | Major Eurozone issuer |
| Canada | Canada Bonds | AAA | Resource-rich; fiscally stable |
| Emerging markets | Various | BB to A range | Higher yields; credit and currency risk |

How Bond Prices and Yields Work
Bond prices and yields move in opposite directions. This inverse relationship is the single most important thing to understand about bond investing.
If interest rates rise: New bonds offer higher coupons. Existing lower-coupon bonds become less valuable, so prices fall and yields rise.
If interest rates fall: New bonds offer lower coupons. Existing higher-coupon bonds become more valuable, so prices rise and yields fall.
Duration measures price sensitivity to rate changes:
- A 10-year Treasury with duration of approximately 9 years falls about 9% if rates rise 1%
- A 30-year Treasury bond with duration of approximately 18 years falls about 18% if rates rise 1%
This is why the 2022 bond market, with the fastest rate-hiking cycle in 40 years, produced the worst year for bonds in U.S. history. Long-term Treasury bonds lost 30% or more as the Fed raised rates from near zero to over 5%.
The Risk-Free Rate and Its Importance
The 10-year Treasury yield is the most important number in finance because it is the benchmark risk-free rate used to:
| Application | How Used |
|---|---|
| Stock valuation | DCF models discount future cash flows at risk-free rate + risk premium |
| Bond pricing | All other bonds priced as spread above Treasuries |
| Corporate lending | Banks price loans as Treasury yield + credit spread |
| Mortgage rates | 30-year mortgages closely track 10-year Treasury + spread |
| Hurdle rates | Companies use risk-free rate + equity risk premium as investment hurdle |
When the 10-year yield rises significantly, it reprices virtually every financial asset simultaneously. Stocks, real estate, bonds, and all credit instruments feel the impact. The yield curve, which plots Treasury yields across maturities, is one of the most closely watched recession indicators in economics.
TIPS: Inflation-Protected Government Bonds
Treasury Inflation-Protected Securities (TIPS) have their principal adjusted by CPI:
| Feature | Regular Treasury | TIPS |
|---|---|---|
| Principal | Fixed | Adjusts with CPI monthly |
| Coupon rate | Fixed % of face | Fixed % of inflation-adjusted principal |
| Return | Nominal | Real (inflation-protected) |
| Best environment | Stable or falling inflation | Rising inflation |
Example: $10,000 in TIPS at 2% real yield. If CPI rises 3% that year:
- New principal: $10,000 x 1.03 = $10,300
- Annual interest: $10,300 x 2% = $206
- Effective nominal return: approximately 5% (2% real + 3% inflation)
The "real yield" on TIPS can turn negative when investors are willing to accept below-inflation returns for safety. This happened during 2020-2021 when 10-year TIPS real yields fell to -1%.
I-Bonds: Savings Bonds for Individuals
Series I Savings Bonds offer a unique combination of inflation protection and safety. As of May 2026 through October 2026, I-Bonds earn a composite rate of 4.26%, which includes a fixed rate of 0.90% (locked for the 30-year life of the bond) plus a semiannual inflation rate of 1.67%.
Key features of I-Bonds:
- Maximum purchase of $10,000 per person per calendar year through TreasuryDirect
- Interest compounds semiannually and is tax-deferred until redemption
- Federal tax on interest only; state and local tax exempt
- Must be held for at least 1 year; 3-month interest penalty if redeemed before 5 years
- As of January 2025, paper I-Bonds are no longer issued; all purchases are electronic

Key Points to Remember
- U.S. Treasuries are the safest investment in the world, backed by the full faith and credit of the U.S. government
- T-Bills (under 1 year), T-Notes (2-10 years), and T-Bonds (20-30 years) are the main categories
- The 10-year Treasury yield (4.71% as of July 2026) is the global benchmark risk-free rate that prices all other financial assets
- Bond prices and yields move inversely: rising rates cause falling bond prices
- Duration determines price sensitivity: longer duration means more sensitivity to rate changes
- TIPS protect against inflation by adjusting principal with CPI
- I-Bonds currently pay 4.26% and offer tax-deferred, inflation-linked returns for individual investors
Common Mistakes to Avoid
- Assuming government bonds are risk-free in all senses: U.S. Treasuries have no default risk, but they carry significant price risk when interest rates rise. "Risk-free" refers to credit risk only.
- Ignoring duration in a rising rate environment: Long-term Treasury bonds lost 30%+ in 2022 as rates surged. Duration risk is very real, and investors who held long-dated bonds felt it directly.
- Not using I-Bonds when yields are attractive: During 2021-2022, I-Bonds paid 7% to 9.6% because inflation was high. Many investors missed this risk-free, tax-deferred return. At 4.26% in 2026, they remain a useful inflation hedge for conservative savings.
- Confusing yield with total return: A bond's yield is not the same as its total return. If rates rise after you buy, your bond's price falls, and your total return can be negative even with a positive yield.
- Overweighting long-term bonds for "safety": Long-term Treasuries are safe from default but volatile in price. If you need the money before maturity, short-term T-Bills or a bond ladder may be more appropriate.
Frequently Asked Questions
Q: How do I buy Treasury bonds directly? A: Purchase directly from the U.S. government at TreasuryDirect.gov with no fees or commissions. You can also buy through a brokerage account in the secondary market, which offers more flexibility for selling before maturity.
Q: Are Treasury bonds taxed? A: Federal tax applies to Treasury interest income. State and local taxes do not apply, which is a significant advantage for residents of high-tax states like California (state income tax up to 13.3%).
Q: What is the difference between a Treasury bond and a savings bond? A: Savings bonds (Series I and EE) are non-marketable: you cannot sell them to another investor, and you redeem them directly with the Treasury. Marketable Treasuries (T-Bills, T-Notes, T-Bonds, TIPS) trade on secondary markets through brokerages.
Q: Should I hold government bonds in my portfolio? A: Most financial advisors recommend some bond allocation for diversification, especially as you approach retirement. The right mix depends on your risk tolerance and time horizon.
