Bonds

If you have followed the financial news recently, you have probably heard a great deal about Treasury yields, rising interest rates and volatility in the bond market. Bonds do not ordinarily attract the same attention as stocks, but they play an enormous role in the financial system and changes in bond yields can affect everything from mortgage rates to stock prices.

Here is what investors need to know.

What is a bond?

At its simplest, a bond is a loan.

When you purchase a bond, you are lending money to a government, municipality or company. In return, the borrower generally agrees to pay you interest and return your principal when the bond matures.

The U.S. government issues Treasury securities to finance its operations. These securities are commonly grouped by maturity:

  • Treasury bills mature in one year or less.
  • Treasury notes generally mature in two to ten years.
  • Treasury bonds have longer maturities, typically 20 or 30 years.

Because Treasury securities are backed by the full faith and credit of the U.S. government, they are generally considered to have very low credit risk. Their prices can still fluctuate, however, particularly when interest rates change.

What is a Treasury yield?

A bond’s yield is the return an investor expects to receive based on the bond’s interest payments and its current market price.

Although the terms “interest rate” and “yield” are often used interchangeably in the news, they are not always the same. A bond may have a fixed interest payment, but its market price can rise or fall after it is issued. As the price changes, so does the yield available to a new buyer.

The easiest way to remember the relationship is:

When bond prices fall, yields rise. When bond prices rise, yields fall.

Imagine that an existing bond pays $40 of annual interest. If newly issued bonds begin offering more attractive interest payments, investors will generally be unwilling to pay full price for the older bond. Its price must fall until its effective yield becomes competitive with the rest of the market.

This inverse relationship between bond prices and yields is one of the most important principles of bond investing.

Why are Treasury yields rising?

The yield on the 10-year Treasury is approaching 4.8%, while the 30-year Treasury yield had moved above 5%. These are meaningful levels because Treasury yields serve as reference points for borrowing costs throughout the economy.

There is rarely a single reason that yields move. Today’s bond market is responding to several forces at once.

1. Inflation remains a concern

Inflation reduces the future purchasing power of a bond’s fixed payments.

If an investor is going to lend money for 10 or 30 years, that investor wants to be compensated for the possibility that a dollar will buy less in the future. When inflation, or the risk of future inflation rises, investors may demand a higher yield.

Energy prices and geopolitical events can intensify this concern because higher oil and transportation costs can spread throughout the economy. Even if an inflation increase proves temporary, the uncertainty alone can create volatility in longer-term bond yields.

2. Expectations for Federal Reserve policy are changing

The Federal Reserve directly controls a very short-term interest rate called the federal funds rate. It does not directly set the 10-year or 30-year Treasury yield.

Longer-term yields are determined by the market and reflect investors’ expectations for future inflation, economic growth, Federal Reserve policy and the additional compensation investors require for committing money for a long period.

If investors believe the Federal Reserve may keep rates elevated, or raise them further, to address inflation, Treasury yields can rise before the Fed actually makes a change. The Federal Reserve reported in July that Treasury yields had risen during 2026 as markets anticipated a higher path for short-term rates.

3. The federal government is borrowing significant amounts of money

When federal spending exceeds federal revenue, the Treasury must issue additional securities to finance the difference and refinance maturing debt.

For the July through September 2026 quarter, the Treasury estimated that it would borrow approximately $739 billion in privately held marketable debt.

Supply and demand matter in the bond market just as they do elsewhere. When the supply of Treasury securities grows, investors may require more attractive yields to absorb that supply, particularly when inflation and fiscal policy are already sources of uncertainty.

This does not mean that demand for Treasuries has disappeared. The Treasury market remains one of the largest and most actively traded financial markets in the world. It does mean that the price investors require to lend money to the government can change.

4. The adjustment is global

The recent increase in government bond yields has not been limited to the United States. Yields have also moved higher in several major overseas markets as investors reconsider inflation, government borrowing and central-bank policy around the world.

Because global investors can choose among many bond markets, changing yields overseas can influence demand for U.S. Treasuries as well.

Why does the bond market matter to the economy?

The Treasury market acts as a foundation for interest rates throughout the financial system. Treasury yields are often described as a “base rate” because many other loans and investments are priced in relation to them.

Mortgages and housing

Thirty-year mortgage rates tend to move in the same general direction as the 10-year Treasury yield, although the relationship is not exact. Mortgage rates also include compensation for credit, prepayment and other risks.

When Treasury yields rise, mortgage rates often remain higher as well. That can make monthly payments less affordable, reduce home-buying activity and slow demand for renovations and other housing-related spending.

Business borrowing and investment

Companies frequently borrow by issuing bonds or obtaining loans priced relative to market interest rates.

Higher yields can increase the cost of financing a new building, purchasing equipment, expanding a business or funding an acquisition. Some projects that made economic sense when borrowing costs were lower may be postponed or canceled when financing becomes more expensive.

Over time, that can moderate economic growth and hiring.

Government finances

Higher Treasury yields also mean that the federal government must pay more interest when issuing or refinancing debt.

As interest expense consumes a larger share of the federal budget, policymakers may face more difficult decisions about taxes, spending and future borrowing. This is one reason investors are paying increased attention to Treasury auctions and federal budget projections.

Stock market valuations

Bonds and stocks compete for investor capital.

When Treasury yields are low, investors may be more willing to accept the uncertainty of stocks in pursuit of higher returns. When high-quality bonds offer more meaningful income, investors have a more attractive alternative.

Higher yields can also reduce the present value that investors assign to a company’s future earnings. This effect can be especially noticeable among companies whose valuations depend heavily on profits expected many years from now.

That does not mean stocks must decline whenever yields rise. It does mean that higher yields can create a more demanding environment for stock valuations.

Consumer spending

Higher market rates can eventually influence auto loans, credit cards and other forms of consumer borrowing. As financing becomes more expensive, households may spend less or delay major purchases.

This is one of the ways tighter financial conditions can help slow inflation, but it can also slow the broader economy if borrowing costs remain elevated for an extended period.

Are higher yields good or bad for bond investors?

The honest answer is: it depends on the investor’s circumstances and time horizon.

Rising yields can be uncomfortable for someone who already owns bonds because the market value of existing fixed-rate bonds may decline. Longer-maturity bonds generally experience larger price movements than shorter-maturity bonds when rates change.

For investors putting new money to work, however, higher yields mean that bonds can provide more income than they did during the ultra-low-rate environment of the previous decade.

For an individual Treasury security held to maturity, interim price fluctuations may be less important, assuming the investor does not need to sell beforehand. The investor continues receiving the promised payments and receives the principal at maturity, subject to the issuer’s ability to pay. Bond funds do not have one shared maturity date and will respond differently as their holdings mature, are sold or are replaced.

The same development, higher yields, can therefore create both short-term price pressure and better long-term income potential.

Does a rise in yields predict a recession?

Not necessarily.

The bond market contains valuable information, but no single yield level can reliably forecast the economy. Yields may rise because investors expect stronger growth, greater inflation, additional government borrowing, tighter Federal Reserve policy or some combination of these factors.

It is often more useful to think of the bond market as a constantly updating assessment of economic conditions rather than a definitive prediction.

What should long-term investors take away from the headlines?

Periods of bond-market volatility can feel unsettling, particularly because bonds are often viewed as the more stable part of a portfolio. But “stable” does not mean that prices never change.

Bonds may serve several different purposes:

  • Generating income
  • Preserving capital
  • Providing liquidity for future spending
  • Reducing overall portfolio volatility
  • Diversifying equity exposure

The appropriate bond allocation, and the mix of short-, intermediate- and long-term bonds, depends on the purpose that money needs to serve.

Rather than trying to predict the next movement in interest rates, we believe it is more helpful to ask whether a portfolio’s bond allocation remains aligned with the investor’s income needs, expected withdrawals, time horizon and overall financial plan.

The bond market is prevalent in the news because it touches nearly every part of the economy. Treasury yields help determine the cost of money, influence investment valuations and reflect changing expectations about inflation, growth and government policy.

While the daily headlines may be dramatic, the role of bonds in a well-designed financial plan is much more practical: providing income, stability, liquidity and balance according to each investor’s specific needs.
