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

U.S. Treasury yields respond to a steady tug-of-war among Federal Reserve (Fed) policy, inflation, growth expectations, and bond supply. These forces influence Treasury prices, shape returns for current bondholders and create new income opportunities for investors putting money to work today. Current yields appear to compensate investors for those core drivers, although U.S. deficit spending could increase future Treasury issuance and deserves continued monitoring.

For investors building resilient portfolios, Treasuries can serve several roles at once. They can help support stability, provide liquidity and generate income without taking on corporate credit exposure. “Treasuries offer reliable, high-quality income, while adding a unique source of diversification to portfolios,” says Bill Merz, head of capital markets research with U.S. Bank Asset Management Group.

What drives Treasury yields and bond price movements?

Treasury yields currently range from roughly 3.6 %-5.2%, depending on maturity, giving investors meaningful income opportunities relative to the last 20 years. Even with explicit U.S government backing, Treasury prices often fluctuate before maturity as interest rates, inflation expectations and supply conditions change. Those price moves can influence investors who rebalance portfolios, harvest gains or manage interest rate risk, especially because longer-term maturity bonds tend to react more sharply when yields change.

“Our proprietary fair value model indicates current Treasury prices fairly compensate investors for the risks we evaluate,” Merz notes. In that model, Fed policy rate expectations account for about three-quarters of the fair value yield, making them the dominant long-term driver in this framework. Other forces can still influence yields at the margin, including new issuance tied to deficit spending and the role Treasuries play when investors seek diversification from equities. ¹ This framework helps identify which force has the greatest influence on yields at a given point in time. It also helps investors separate near-term market noise from longer-term trends in policy, inflation, and growth.

How inflation and Fed policy shape Treasury yields

Inflation and inflation expectations remain closely linked to Treasury yields because inflation erodes the purchasing power of fixed coupon payments over time. Today, Treasury yields are high enough to provide an income stream above expected inflation. A 10-year Treasury yield of approximately 4.5%, compared with 2.5% expected inflation, implies a buy-and-hold investor could expect a “real” or inflation-adjusted return of about 2.0%.

Inflation can also influence bond prices before maturity. Oil prices have risen in 2026, lifting inflation expectations and changing how investors assess the likely Fed policy response. Market prices have shifted from an expected Fed interest rate cut to the possibility of an interest rate hike in 2026 to quell potential inflation. Treasury yields rose and bond prices fell as investors demanded more income return to compensate for inflation risk and rate hike expectations, although long-run growth and inflation trends still suggest Treasuries reasonably reflect underlying economic conditions.

The Fed can shape Treasury yields through two primary channels: the policy rate and the size of its balance sheet. By setting the federal funds rate, an overnight lending rate between banks, the Fed establishes a baseline that most directly affects bank borrowing costs and short-term Treasury yields. Longer-term yields then respond as investors weigh whether to reinvest in shorter maturities or lock in longer-maturity income.

The Fed reduced its target short-term rate by 1.75% across 2024 and 2025, bringing the target range to 3.50-3.75%. Current interest rate pricing implies investors expect that the Fed may remain cautious as it balances inflation, energy prices and labor-market conditions.

The Fed can also influence Treasury yields by buying or selling Treasuries for its own account. The Fed recently shifted from reducing its Treasury holdings, by not replacing maturing bonds, to gradually buying short-term Treasury bills, primarily to support smooth funding-markets functioning. That purchase activity means private investors absorb less aggregate supply, which can help steady yields at the margin.

Do deficit spending and Treasury supply affect bond markets?

America’s fiscal trajectory remains a focus for investors, especially with the federal deficit exceeding 5% of gross domestic product. Ratings agencies have cited that backdrop in recent warnings, including Moody’s downgrade of U.S. debt in 2025, Fitch’s downgrade in 2023 and S&Ps downgrade in 2011. Financial markets reacted only mildly, however, with U.S. bonds performing largely in line with bonds from other developed economies during the same period.

“We do not see strong evidence of the U.S. fiscal situation heavily influencing bond yields right now based on our calculations, but we must monitor government, economic and market data for signs of change,” says Merz. Federal government policy choices, including deficit spending, tax and tariff changes can still alter the deficit path. The Congressional Budget Office projects elevated deficits over the next decade as spending exceeds tariff and tax revenue.

The U.S. Treasury Department has recently relied on higher short-term bill issuance to fund government spending that exceeds receipts. That approach has helped prevent increased supply from lifting intermediate- and long-term yields. The Treasury stated in May 2026 that it plans to continue this policy, keeping medium- and long-term bond auction sizes stable for the next several quarters, although continued deficit spending could eventually require greater issuance in those maturities.

Why global demand continues to support the Treasury market

Recurring headlines suggest foreign investors may step away from U.S. assets, but recent data tells a different story. International buyers increased their Treasury holdings by nearly $300 billion over the 12 months through March 2026. That demand provides important support for Treasury prices, even when investor sentiment shifts.

Concerns about a foreign investor buying “strike”, which could lift yields, have not shown up in market prices. “We see no evidence of a buyers’ strike based on the data,” says Merz. Investors should still consider that scenario as a risk, but current market evidence does not suggest a broad retreat from Treasury demand.

Treasury auction results provide another real-time window into investor appetite. Recent outcomes are only slightly weaker than long-run averages and common auction indicators still point to generally normal bond market functioning. “Domestic demand fluctuated over the past couple years on investor inflation and deficit concerns, but Treasury auction results are near-normal,” says Merz, and recent regulatory changes could also increase financial institutions’ capacity to hold Treasuries.

How economic growth influences long-term Treasury yields

Over long periods, long-term Treasury yields tend to coalesce near nominal economic growth, which combines real growth and inflation. The relationship is not perfect, because unusually loose or tight central bank policy can push yields away from that long-term reference point. Still, nominal growth gives investors a useful way to judge whether long-term Treasury yields look unusually high or low relative to the broader economy.

By this measure, long-term Treasury yields remain within a normal historical range. That does not remove the possibility of short-term volatility, especially when inflation, energy prices and Fed expectations move quickly. It does suggest current yields broadly reflect the economy’s underlying growth and inflation backdrop rather than a clear signal of Treasury market stress.

What Treasury bonds can do in a diversified portfolio

Treasuries can help investors pursue steadier income while dampening volatility from riskier asset prices. Investors seeking more consistent returns may benefit from larger high-quality bond allocations, while more risk-tolerant investors can use Treasuries as a stabilizing counterweight. Because high-quality bonds often move differently than stocks and other higher-risk assets, Treasuries can support diversification aimed at managing overall portfolio volatility.

U.S. Treasuries remain a core holding for many diversified portfolios. The market has adapted to higher issuance so far through broader participation and regulatory support. Today’s yields offer meaningful income opportunities that fairly compensate investors for policy expectations, supply, inflation, and diversification properties.

Investors should still monitor the risks that can shift Treasury yields and bond prices. Fed policy, new legislation, issuance patterns and inflation expectations can all change the income outlook. Discuss your portfolio positioning with a U.S. Bank wealth professional to determine how U.S. Treasuries may fit alongside your income needs, risk tolerance and long-term investment objectives.

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.
