Diversification isn't dead: Bonds poised to offer balance

Strong yields and the prospect of a less hawkish Federal Reserve are breathing new life into bond portfolios. Although declining inflation is a reason for optimism after a difficult year, investors can’t be certain just yet if the prolonged market volatility is over.

That’s because even if the Fed’s hiking cycle is almost done, the cumulative effect of the aggressive tightening campaign on consumers and businesses remains unclear. Markets expect growth to slow and have penciled in a mild recession in the United States.

However, that picture could change as unemployment and consumer spending data come in. “We could still be in for a bumpy road, though I don’t see the same level of interest rate volatility for bonds,” says David Hoag, portfolio manager for The Bond Fund of America® and American Funds® Strategic Bond Fund.

Diversification and the 60/40 portfolio

Investors who fled volatile stock markets in 2022 faced a new problem: Bonds weren’t offering the stability they had expected. The year-long stretch of both stocks and bonds posting losses left many investors questioning the relevance of the 60% equities/40% bonds portfolio and whether bonds could still provide diversification from equity market downturns.

The profound pessimism in markets globally was tied to central banks raising rates to rein in decades-high inflation. The pain was acute with both the S&P 500 Index and the Bloomberg U.S. Aggregate Bond Index down double digits. The losses were also unique, with 2022 being the only time in 45 years that stocks and bonds declined in tandem.

“Last year was very disappointing since bonds didn’t do what people expected, but at the same time, it was what the Fed needed to happen to bring inflation down,” Hoag explains. “The culprit for the chaos in both stocks and bonds last year was the Fed’s aggressive rate hikes. I think it’s reasonable to say that bonds will go back to offering diversification benefits as we near the end of the tightening cycle.”

Most investors had never faced a year as challenging as 2022

This is a scatter chart with each point representing an annual stock and bond market return. It shows 2022 as the only point squarely in the lower left quadrant, indicating a significant decline for both stocks and bonds in that year. One point shows a bond return of zero and a decline of about 4% for stocks. A handful of points are located on or below the horizontal axis, with positive return for stocks. The vast majority of points are above the horizonal axis, indicating positive bond returns, whether positive or negative stock returns.

Bond funds are also offering more income and higher return potential. The yield on the Bloomberg U.S. Aggregate Bond Index, a widely used benchmark for investment-grade (BBB/Baa and above) bond markets, ended 2022 at 4.68% compared to a yield of 1.75% on December 31, 2021. The total return of a bond fund consists of distributions, price changes and interest paid, and the latter has been rising.

With high returns potential from core bond funds, investors may not need to take as many risks in their equity or bond portfolios, Hoag says. “The magic today is that core bond funds offer more cushion from the income component compared to the start of last year.”

This also means that even amid modest price or interest rate volatility it may be easier to achieve a positive total return in 2023.

Despite the very low yields that investors have faced since the 2007–2008 global financial crisis, healthier income from bonds like we see today is closer to the historical norm. In the past three decades — which includes periods of price or interest rate volatility — core bond total returns were driven predominantly from the interest or coupon component, not price changes.

Historically, income has dominated long-term total return

Three bars represent the prior three decades starting in 1990. Each bar shows the coupon return significantly dominating total return amid those decades. In the 1990s, total return was 7.7% with coupon accounting for all but 0.3% provided by price return. In the 2000s, total return was 6.6% with coupon accounting for all but 0.9% provided by price return. In the 2010s, total return was 3.8% with coupon return accounting for all but 0.8%.

Inflation has declined but the Fed can’t declare victory

Whether Fed officials feel confident that they have vanquished inflation is important. The last few months have offered some relief as inflation rates declined from their peak, which has allowed central banks to slow their rate hikes. The Consumer Price Index (CPI), a measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services, rose 6.5% in the year through December, down from 7.1% for the 12 months through November. The Fed’s preferred core inflation measure, which strips out food and energy prices, slowed annually to 5.7% in December from 6.0% a year earlier.

“I see core CPI continuing to decline this year to a range of 3.5% to 4.0%, which is still above the Fed’s 2.0% target level,” says Timothy Ng, fixed income portfolio manager for American Funds Inflation Linked Bond Fund®.

Pandemic-related supply chain disruptions were a big contributor to high inflation in 2022, and that problem has largely dissipated. The demand for workers also fed into higher prices since companies passed on to consumers the increased costs of hiring. There are signs that the worker shortage is beginning to improve, and more companies have paused hirings or announced layoffs.

“Still, the Fed can’t declare victory yet, and the fine-tuning that’s going to happen may be a source of volatility in the market overall,” Ng notes.

Inflation is easing, allowing Fed to slow rate hikes

This is a chart showing two lines, one for CPI and one for core CPI. Both were at or below 2.0% until roughly March of 2021, when each began to rise, with CPI increasing more quickly than Core CPI. CPI continued to climb until about June 2022, when it peaked at 9.1% and has since declined to about 6.5%. Core CPI had a similar trend, peaking at 6.6% in September 2022 and since declining to 5.7%.

Signs of an economic slowdown … or a recession?

What’s next for policymakers is a thorny question. Rapid rate hikes are necessary to cool inflation, but too much tightening could severely hurt the economy and job figures.

Investors don’t expect a repeat of the same interest rate volatility that hit bond markets in 2022. Inflation is moving in the right direction, and the Fed has already dialed down the pace of hikes, giving officials time to see their policy impact on the broader economy.

Assuming growth continues to deteriorate, the market expects the Fed to pivot from rate hikes to rate cuts in late 2023. Such a dramatic move would positively impact bond prices, as yields would begin to fall. That’s a major reason why high-quality bonds tend to provide diversification from equities: The Fed swoops in to ease policy as stocks get hammered by a sagging economy.

Rate expectations have dramatically changed from 2022

The chart shows three sets of bars. Each set corresponds to yields for 2-year, 5-year and 10-year Treasuries. Each set contains three bars, one for the change in yield for 2022, one for the market expectation’s change through 2023, and one for the market expectation’s change through 2024. The 2022 bars show steep increases in yields of 3.70%, 2.74% and 2.37%, respectively. The bars showing change through 2023 show small declines of 0.47%, 0.18% and 0.04%, respectively. The bars showing change through 2024 show small declines of 0.71%, 0.24% and 0.02%, respectively.

“Investors have been buying Treasuries in part because they expect a mild recession,” Hoag says. The market is also expecting rates to decline by year-end since the Fed may want to get to a rate that is considered “neutral,” or a place where policy is neither stimulating nor restricting economic growth, as the economy weakens further.

Signs of a slowing economy have started to appear beyond a decreased demand for housing. Consumers have begun to pull back on buying cars, furniture and even fuel with retail sales down 1.1% in December compared to the prior month, according to the U.S. Department of Commerce. The Producer Price Index, which reflects inflation at the supplier level, also slowed in December to 6.2% from 7.3% the previous month.

“Once there are some weaknesses, they tend to snowball — and above a certain threshold, it usually means the economy is in a recession,” says Ng.

Under this scenario, actively managed core bond funds that hold high-quality bonds will likely do better than those that hold lower rated debt.

“I’m finding more value in high-quality mortgages rather than investment-grade corporate bonds since I am concerned that the Fed may have already gone too far and tightened by too much,” Hoag says.

The search for stability amid volatility

After a series of jumbo rate hikes, the Fed has entered a new phase of smaller increases that give officials time to consider the impact of higher borrowing costs.

“With inflation finally coming down, the likelihood that bond markets experience another year of massive hikes in 2023 is very low,” Ng adds. This is a welcome scenario for bond investors, as it means core bond funds could again offer diversification benefits.

“Economic indicators are dropping from the heavy lifting the Fed did last year, and there’s bound to be stock market volatility. If we enter a recession, policymakers could look to rate cuts, which could help boost returns for core bond funds,” Hoag notes.
