Putting 5% Treasury Yields Into Perspective
Market commentators love large, round numbers that make good headlines – $40 trillion national debt, the Dow Jones Industrial Average reaching 50,000, and most recently, the 10-year U.S. Treasury yield reaching 5%.
These milestones can be meaningful – and some certainly warrant further attention – but when it comes to the recent rise in bond yields, an important question for investors is: How concerned should we be?
5% Is a Milestone - But This Isn't 2022
For perspective, it is helpful to start with what the increase in bond yields is not: a repeat of 2022.
In 2022, the 10-year Treasury rate almost tripled, rising from 1.52% to 3.88%. Because bond prices generally move in the opposite direction of yields, that rapid increase caused significant losses across the bond market. The iShares Core U.S. Aggregate Bond ETF, an intermediate-maturity fund tracking Treasuries, corporate bonds and mortgage-backed securities, declined approximately 13% that year, making an already difficult environment for equity investors even more challenging.
In contrast, the 10-year Treasury started this year at 4.18%, a much higher starting point. As a result, it would require a significant upward movement in yields to have a negative impact on bond values similar to what was experienced in 2022. So far this year, the iShares Core U.S. Aggregate Bond ETF is down about 1%, meaning the decline in bond prices has been significantly cushioned by the higher income bonds now generate.
What is Pushing Bond Yields Higher?
There is no single explanation for the recent rise in longer-term interest rates. Three factors have been particularly important: higher inflation expectations, large increases in bond issuance from the corporate sector, and growing concerns about the total amount of U.S. government debt.
Inflation Remains a Key Driver
Inflation expectations have moved higher as volatile energy prices continue to climb. In fact, 10-year Treasury yields and crude oil prices have moved together for much of the past six months.
But the concern extends beyond energy. Inflation has also become more widespread across the economy over the past twelve months.
In fact, Fed Chair Warsh noted the breadth of inflation in his Jackson Hole Economic Symposium commentary, where he cited data showing that 54% of the components within the Personal Consumption Expenditures (PCE) – the Fed’s preferred inflation measure – were rising above 3% on an annualized basis over the past 12 months. That compares to a pre-pandemic 20-year average of 32%.
In other words, inflationary pressure is appearing across a broader range of goods and services rather than being concentrated in just a few categories.
That has kept bond investors attentive to inflation risk and has led them to demand higher yields for longer-term bonds. This dynamic has put additional pressure on the Federal Reserve, which raised the federal funds rate by 25 basis points to a range of 3.75% - 4.00% this week. Commentary from Fed Chair Warsh affirmed that the Federal Open Market Committee (FOMC) is serious about tackling rising inflationary pressures.
More Bonds Are Competing for Investor Dollars
Another big contributor to rising bond yields has been a significant increase in corporate borrowing. The rapid buildout of artificial intelligence infrastructure and data centers requires substantial investment, which has prompted many companies to access the bond market for capital to finance these projects. That additional supply means corporate issuers are effectively competing with the U.S. government and other borrowers for investment dollars. This increase in overall bond supply has forced issuers to pay higher rates to find willing buyers.
Government Borrowing is Also in Focus
Finally, the growing level of U.S. government debt is another factor receiving increased attention from investors. The Treasury must continue issuing substantial amounts of debt to finance federal borrowing. When bond supply rises faster than demand, investors may require higher rates to hedge the risk that rates may move much higher. At the same time, some traditional large buyers of U.S. Treasuries have also started to diversify into other assets, reducing demand at a time when Treasury supply is increasing.
What Higher Rates Mean for Markets and the Economy
Higher interest rates don’t necessarily bring stock prices lower, but they do present headwinds to this almost four-year bull market. Bond yields above 5% present a more attractive opportunity for investors as they can “lock in” a competitive and dependable rate of return without the volatility of the stock market. Thus, money targeted for investment may see a larger allocation to bonds instead of stocks.
Higher long-term rates also affect the broader economy by making borrowing more expensive for both businesses and individuals.
Housing is one area where the impact can be especially visible. Historically, construction has driven a good deal of economic activity, yet in the last few years that source of economic growth has declined. With mortgage rates now over 7%, higher borrowing costs could further weigh on consumer demand for new homes, renovations, and housing-related purchases such as furniture and appliances.
Higher Yields Also Create Opportunities
While a 5% 10-year Treasury yield creates challenges in some areas of the market, higher yields should not be viewed only as a negative development. Rising yields can temporarily reduce the market value of existing bonds, but they also allow investors to reinvest at more attractive rates and can increase the income generated by fixed-income portfolios over time. For long-term investors, both sides of that equation matter.
What It Means for Portfolios
Our bond portfolios entered this environment with an important advantage: holdings were already positioned with relatively shorter maturities, helping to mitigate any substantial rise in interest rates at the start of this year. Therefore, our fixed income holdings are not as sensitive to the recent interest rate moves seen across the yield curve.
If rates continue to rise, we may continue to favor shorter-term maturities and a pivot to higher-quality bonds, where today’s yields can provide attractive income without taking unnecessary interest rate or credit risk.
Corporate bond credit spreads – the additional yield investors receive for owning corporate bonds rather than comparable U.S. Treasuries – are at historically low levels. A shift to higher-rated and shorter-maturity investment-grade bonds could provide insulation from potential spread widening as corporations refinance debt in a higher rate environment. Higher interest rates may also present an opportunity to right-size risk in our equity allocations after the significant run-up in high-beta names, rebalancing portfolios to neutral positions.
Stay Focused on the Long Term
Periods of changing interest rates can create both challenges and opportunities, which is why we continue to focus on diversification, quality and disciplined portfolio management rather than reacting to individual headlines. We remain attentive to how inflation, Federal Reserve policy and changing bond yields may affect both fixed-income and equity markets and will adjust portfolios when we believe conditions warrant.
