U.S. Treasuries: Balancing income and diversification opportunities with policy risks

U.S. Treasuries play a larger role than their place in investment portfolios may suggest. Treasury yields help set borrowing costs for consumers, businesses and governments around the world, and investors often use them as a reference point when valuing stocks, bonds, real estate and other assets. The rise in Treasury yields therefore affects financial conditions as well as the income available from high-quality bonds.

Treasury yields reflect Federal Reserve (Fed) policy, inflation, economic growth, bond supply and investor demand. Those forces move Treasury prices, shape returns for existing bondholders and create income opportunities for investors putting money to work. Yields appear to compensate investors for many of these drivers, although persistent U.S. deficits could increase future issuance and pressure bond prices.

Treasuries can provide income, ready access to cash and diversification without the credit risk that a company may miss required payments. “Treasuries offer reliable, high-quality income and a distinctive source of portfolio diversification,” says Bill Merz, head of capital markets research with U.S. Bank Asset Management Group. “Investors should balance those benefits against the possibility that inflation, policy changes or growing bond supply keep long-term yields elevated.”

How Treasury bonds and interest rates affect investors

Treasury yields range from roughly 3.7%–5.3%, depending on maturity, providing meaningful income compared to the last 20 years. U.S. government backing supports repayment of principal and interest, but Treasury prices can still change before maturity as interest rates, growth and inflation expectations and supply conditions shift. Longer-term bonds generally experience larger changes than shorter-term bonds when yields move, so investors should match maturities to their spending needs and tolerance for price volatility.

Our fair value model estimates a reasonable level for Treasury yields based on expected interest rates, new bond supply and the diversification value Treasuries can provide. Yields stand above that estimate, suggesting that investors also require compensation for persistent inflation, firm economic growth or fiscal uncertainty. Long-term government bond yields have also reached multi-year highs in Germany, France and Japan, showing that the increase extends beyond the United States.

High-quality corporate bond issuance has also increased substantially in 2026 and competes with Treasuries for investor demand. Companies have borrowed to fund artificial intelligence infrastructure, adding to the amount of longer-term debt that investors must purchase. We believe this additional corporate supply has contributed to higher Treasury yields because investors require more income to absorb growing bond issuance across both markets.

How Federal Reserve and Treasury Department policies affect yields

The Fed influences Treasury yields through its policy rate and balance sheet. The federal funds rate, which banks use for overnight lending, most directly affects short-term borrowing costs and short-term Treasury yields. Longer-term yields respond to investors’ expectations for future policy, inflation and growth, as well as the relative appeal of short-term and long-term income.

The Fed lowered its target rate by 1.75% across 2024 and 2025, bringing the target range to 3.50%–3.75%. Market prices indicate that investors expect the Fed may raise rates later in 2026, although new inflation, employment and growth data can change that outlook. The Fed has also shifted from reducing its Treasury holdings to buying short-term Treasury bills to maintain orderly short-term funding markets, while new Fed chair Kevin Warsh has expressed support for a smaller balance sheet over time; if the Fed eventually holds fewer Treasuries, private investors would need to absorb more supply.

The U.S. Treasury Department also influences the mix of securities available to investors. Treasury Secretary Scott Bessent has kept issuance of longer-term notes and bonds stable since mid-2024 while relying more heavily on short-term Treasury bills to finance growing deficits, limiting the increase in longer-term supply. Secretary Bessent recently announced expanded buybacks of older securities to improve trading liquidity, but proposals to fund direct purchases from the Treasury’s General Account could reduce longer-term supply while adding money to the financial system, creating potentially offsetting effects on bond prices and inflation.

How federal deficits and Treasury supply affect bond yields

The U.S. federal deficit exceeds 5% of gross domestic product, increasing the amount of debt the government must finance. Ratings agencies have cited that deficit in recent warnings, including Moody’s downgrade of U.S. debt in 2025, following Fitch in 2023 and S&P in 2011, but financial markets reacted modestly and U.S. bonds generally performed in line with bonds from other developed economies. Ratings changes highlight the long-term fiscal challenge, while market performance indicates that investors continue to assess U.S. debt alongside inflation, economic growth and global interest-rate trends.

“Historically, the U.S. fiscal situation has not exerted a strong influence on bond yields, but rising government bond yields around the world may signal greater attention to budget deficits,” says Merz. “We are watching fiscal policy, economic data and market demand for evidence that the relationship is changing.” Tax policy, tariffs and spending decisions can alter the deficit path, and the Congressional Budget Office projects elevated deficits over the next decade as federal spending exceeds revenue.

Who buys U.S. Treasuries?

A broad mix of U.S. and international investors supports the Treasury market. U.S. investors remain the largest source of demand, while international buyers increased their holdings by nearly $200 billion during the 12 months through June 2026. That diverse ownership base helps the market absorb issuance even as individual countries adjust their holdings.

Recent data do not show a broad foreign buyers’ strike, a sharp pullback in demand that could force yields higher. “We do not see strong evidence that foreign investors are withdrawing from the Treasury market,” says Merz. While some countries reduced their Treasury holdings, overall foreign holdings have increased over the last year.

Treasury auctions provide another timely measure of investor demand. Recent results, based on the volume of bids and the yields required to attract buyers, have only been slightly weaker than long-run averages and continue to indicate orderly market functioning. “Domestic demand has fluctuated with inflation and deficit concerns, but Treasury auction results remain near normal,” says Merz, adding that recent regulatory changes could increase financial institutions’ capacity to hold Treasuries.

How U.S. Treasury bonds support portfolio diversification

Treasuries can provide portfolio income while helping offset volatility from stocks and higher-risk assets. Investors who prioritize stability may use a larger allocation to high-quality bonds, while investors with greater tolerance for price changes may use Treasuries as a counterweight to growth-oriented holdings. Diversification does not prevent losses, but combining assets that respond differently to economic and market conditions can reduce dependence on a single return source.

Higher Treasury yields also raise the starting income available across much of the fixed income market. Corporate, municipal and securitized bonds, which are backed by pools of loans or other financial assets, can offer additional yield and different sources of diversification, although each introduces distinct credit, liquidity and interest-rate risks. Investors can evaluate those opportunities alongside Treasuries, rather than concentrating their fixed-income allocation in one market segment.

Treasury yields and bond prices can change as Fed policy, legislation, debt issuance and inflation expectations evolve. Significant market developments can alter the balance between income opportunity and price risk, so investors should reassess their exposure when those conditions shift. Discuss your portfolio positioning with a U.S. Bank wealth professional to determine how Treasuries and other fixed-income investments may fit alongside your income needs, risk tolerance and long-term investment objectives.

What are U.S. Treasuries and how do they function?

Treasury securities are debt instruments issued by the U.S. government to fund current operations or major capital investments. In essence, investors who purchase these securities are loaning money to the federal government. Depending on the type of security, the government makes regular interest payments to the investor. When the security matures, the investor receives from the government the full (par) value of the loan (bond purchase price).

How the U.S. government issues Treasury securities

As funding needs arise, the U.S. government offers new U.S. Treasury bonds and notes through a public auction system. The government specifies the securities offered in each auction. Large Wall Street institutions bid competitively, specifying the yields they are willing to accept. This process helps establish yields for specific securities that individual investors who participate in a non-competitive bidding process will receive.

Key features of Treasury securities

Investors find the Treasury market attractive for a number of reasons, perhaps foremost because Treasuries are backed by the “full faith and credit” of the U.S. government. That means Treasuries enjoy a de facto “risk-free” status, with investors able to rely on timely interest payments and full repayment of their initial investment when the security matures. Other features include the Treasury market’s healthy liquidity, making it easy to trade Treasury securities on a timely basis; interest payments that are completely exempt from state and local income taxes; and the ability to generate investment gains should a favorable interest rate environment occur after purchasing a Treasury security.

How the Treasury market fits into the broader financial system

The U.S. Treasury market is unique among financial instruments. U.S. Treasuries shape the broader financial system. Because investors generally consider U.S. Treasuries a “risk-free” asset, backed by the U.S. government’s “full faith and credit,” other fixed-income market instruments are benchmarked against them. Rates on other debt securities generally exceed those of Treasuries because they carry more risk. Many global institutions use U.S. Treasuries as collateral to finance large investments. The Federal Reserve (Fed) may use purchases or sales of its Treasury holdings to help shape economic trends. The reliability of Treasuries helps give the U.S. dollar global reserve currency status.

What influences the supply and demand for Treasuries

A variety of factors influence Treasury supply and demand. When demand is high, interest rates tend to moderate. If demand declines, the federal government must pay higher yields to attract investors. The federal government’s deficit spending is the primary driver of supply. The more spending not covered by current revenue (tax receipts), the larger the Treasury supply. Congress frequently must raise the government’s debt ceiling, allowing the U.S. Department of the Treasury to issue additional securities to fund spending. In some cases, supply increases because the government must refinance existing debt as it matures. On the demand side, investors may rush to buy Treasuries in advance of anticipated Federal Reserve (Fed) interest rate cuts. In periods of stock market weakness, investors may engage in a “flight to safety” into Treasuries, also boosting demand. On the other hand, if interest rates are expected to rise, investors may delay locking in long-term debt securities. Likewise, higher inflation tends to make Treasury yields less attractive, as rising living costs erode Treasury bonds’ real (after-inflation) interest rate.

How to interpret changes in the Treasury market over time

Treasury trends can signal broader economic trends. Over the long term, Treasury yields tend to move along a normal curve. This means that the shorter the Treasury security’s maturity, the lower its yield compared with long-term Treasury yields. This reflects investors’ willingness to accept lower yields on shorter-term “loans” to the government while expecting higher yields on longer-term financial commitments. The normal yield curve typically signals investor expectations of a healthy, growing economy. An inverted yield curve occurs when shorter-term securities’ yields exceed those of longer-term securities. This is often considered a recession warning signal, though it doesn’t always lead to a recession. If yields are generally flat across the maturity spectrum, it may mean the economy is in a transitional period, either moving from more rapid growth to slower growth or even a recession, or vice versa.

FAQs

Are Treasury bonds a good investment when interest rates are high?

Treasury bonds can offer higher income when yields are elevated, but prices can still fluctuate before maturity. Investors should match maturities and allocation size to income needs, risk tolerance and time horizon.

What causes Treasury yields to rise or fall?

Treasury yields respond to Federal Reserve policy, inflation expectations, economic growth, Treasury supply and investor demand. Short-term yields tend to track Fed policy more closely, while longer-term yields also reflect inflation, growth and fiscal expectations.

How do Treasury bonds help diversify a portfolio?

Treasuries can provide high-quality income and may help offset volatility from riskier assets. Their role depends on the investor’s goals, liquidity needs and broader asset allocation.
