What are Treasury yields?

Investors collectively owned $28T in US Treasury securities as of 2025.

Bond yields are the returns investors earn from a bond's interest—and they're a key economic barometer.

If the US government paid off its debt, it could disrupt the entire bond market, as Treasury bonds are among the most common bonds for investors and the majority of the national debt is in bonds.

Treasury bonds, notes, and bills are critical vehicles for the federal government to raise money for public expenses and manage the national debt.

For everyday Americans, a relatively high national debt can lead to higher interest rates on financial products such as mortgages.

The US Government sells two types of savings bonds: EE bonds and I bonds

EE bonds have fixed interest rates that the buyer is informed of when they purchase the bond. I bonds, however, earn a rate that can change every six months. A comparative chart details the most significant differences between EE bonds and I bonds.

The national debt is the total amount the US government owes its creditors

This US Treasury page explains what the national debt is, how it accumulates from annual deficits, and why rising debt can affect interest costs, fiscal flexibility, and long-term economic stability.

The bond market is where bonds and other debt securities are traded

Bonds are fixed-income investments allowing individuals to lend a specific amount of money to a large entity, like a government or corporation, for a set amount of time in return for interest paid out over the life of the loan. The bond market is widely considered a key economic barometer.

Investors can buy three main types of bonds: government, corporate, and municipal

Each type has variations of its bond offerings with different interest rates, loan lengths, maturity dates, and terms. Each type also carries its own risks and rewards.

Nearly 70% of the US government’s debt is domestic

This includes intragovernmental holdings like the Social Security Trust Fund and investments from US citizens, banks, and mutual funds. About 30% is foreign-held, with countries like Japan and China as major creditors, investing in US Treasury securities due to their perceived safety.

When the US hits the debt ceiling, the Treasury uses emergency measures to avoid default

After the US reached its debt ceiling in January 2023, the Treasury deployed "extraordinary measures" to keep paying obligations. This article explains the steps, how they work, and why they last only for a limited time. (Some readers may experience a paywall.)

The US debt ceiling is the threshold Congress sets for federal borrowing.

The current federal budget, deficit, and debt, in charts

The US Treasury regularly publishes updated data on the federal budget, and this site hosts visualizations of that data. See reports on spending, revenues, deficits, and where the national debt stands.

Series I bonds are a form of government savings bonds created to shield your investments from inflation

Specifically, I bonds earn interest from both a fixed rate and an inflation rate. This article explains who might benefit from investing in I Bonds—for instance, people seeking to invest savings they do not need to access in the near future.

Interest rates have historically been an indicator of the US economy's overall health.

The national debt consists of public debt and intragovernmental debt.

Are I-Bonds a good investment?

I-Bonds are savings bonds issued by the US government that can help protect savings from inflation. While that sounds positive, I-Bonds have a few disadvantages, too—for instance, these bonds have to be held for at least a year before you can cash out.

There are three main ways to start investing in the bond market

Invest in the boind market through a brokerage, mutual fund or ETF, or the US government. Each has different steps and terms to follow, from starting rates to opening specific accounts. Some bonds are relatively easy to purchase, but the process differs depending on the type of bond you want.

An inverted yield curve has preceded every recession that’s occurred in the last 50 years

Prolonged yield curve inversions can predict recessions, but even brief inversions can cause investors to react with knee-jerk reactions.

The Federal Reserve can set interest rates below zero

Interest rates, the cost of borrowing money, are the primary tool the Federal Reserve uses to control inflation. During periods of deflation, setting interest rates below zero penalizes saving, encourages banks to lend more and moves more cash through the economy.

The federal deficit is the gap between what the US spends and what it collects.

Investing in bonds comes with a few risks

Think: changes in interest rates that impact the bond’s value, or a bond issuer completely defaulting on a loan. There are steps investors can take to lower their initial and future risk when investing in the bond market, such as checking a company's bond rating before investing.

The US government is legally allowed to borrow money from the Social Security Trust Fund surpluses as long as it issues Treasury bonds to the Trust Fund in return and repays those bonds with interest when Social Security needs the money to pay benefits.

How interest rates affect homebuying

Rising interest rates impact every aspect of buying a home. This five-minute article gives a high-level overview of the relationship between the housing market and interest rates.

The Federal Reserve's decisions can impact your money

Car loans, mortgages, business investments—these and more can be drastically impacted by the adjustment of the Federal Reserve’s federal funds rate. Alternatively, savers can earn higher, low-risk yields on their savings when the Fed’s target rate is higher.

Some argue that the rising US national debt has become more important in recent months.

Stablecoins like USDC are backed by real assets including US Treasurys and cash

While Tether (USDT) is primarily backed by US Treasury bills (64.9%), USDC is mostly backed by US Treasury repurchase agreements (49.6%). USDC also goes by the name Circle, given that it is owned by the company Circle Internet Financial.

'Floating rate' loans periodically adjust their interest rates in accordance with economic conditions

When the Federal Reserve began raising interest rates in 2022 to combat inflation, interest payments borrowers owed to private credit lenders increased accordingly. Private credit funds benefited as loan returns increased, making the asset class attractive to investors at the time.

The debt ceiling is a legal cap on how much money the US government can borrow.

The Fed operates within the open market as a competitive bidder of interest rates

Because it’s viewed as a risk-free platform to earn interest, whatever rate it sets becomes the default benchmark. To maintain its target rate prescribed by the Federal Open Market Committee, the Fed has various tools it offers both commercial banks and home loan institutions.

Why countries have credit ratings

Sovereign credit ratings work like national credit scores, measuring a country’s ability and willingness to repay its debt. Moody’s, S&P, and Fitch are the major agencies assigning these ratings, which influence borrowing costs and investor confidence.

The US and Denmark are the only two countries known to abide by a predetermined borrowing limit.

Companies sometimes issue corporate bonds to raise capital

These bonds offer investors regular interest payments in addition to the return of the principal amount at maturity. They allow companies to raise capital without losing ownership.

Some economists argue that the national debt is not a critical concern.

Banks make money by loaning customer deposits and earning interest

This means the interest you earn on your deposits is lower than what the bank earns on the same amount. Banks often keep cash reserves (though a minimum requirement was rescinded in 2020) but generally invest in government bonds, corporate securities, and loans to other banks. During bank runs, depositors withdraw more than the bank has on hand.

Periodically, the Federal Open Market Committee decides whether to raise, hold, or lower the federal funds rate

The federal funds rate is the interest rate at which banks lend their excess funds through the Fed. This influences what banks are willing to pay consumers for their deposits in savings and CD accounts. Typically, the higher the federal funds rate, the higher the interest rates on CDs.

Revenue from tariffs goes to the US Treasury's general fund.

Individual income taxes are the federal government's primary revenue source, see a tracker that breaks down where the rest of the budget comes from

The US government historically makes nearly half of its total revenue last year from individual income taxes. But the US makes also makes money from a variety of other sources, including Medicare taxes and corporate income taxes. However, the federal government has run a deficit since 2001—reaching a peak of $3.13T in 2020.

Understanding the low corporate tax rate in the US

Corporate taxes, which make up roughly a third of the federal government's revenue, have been calculated using a flat 21% rate since the Tax Cuts & Jobs Act of 2017. The current rate is considered low both by historic standards (it averaged over 50% in the 1950s and 1960s) and compared to other countries.

The US has carried debt since 1791

After the Revolutionary War, the US owed $75M to nations like France. Debt builds when spending exceeds revenue, funding programs, wars, and economic recovery efforts. Most debt is domestic, like Social Security bonds, with foreign nations also holding a share.

About 80% of US debt is held by domestic and foreign investors.

Zero-coupon bonds have no regular interest dates over the length of the loan

Instead, they pay all the interest at once when the bond hits its maturity date. These bonds aren’t the right investment for everyone, but they do carry some pros, like a lower initial investment cost.

Local governments borrow money for long-term projects by issuing municipal bonds

When a city needs to build a school, a road, or a water treatment plant, it usually issues a municipal bond—borrowing money from investors to be paid back over time. The market for these bonds now exceeds $4T.

Tariffs are typically paid by the importing company or organization to the US Treasury.
