Wells Fargo Advises Investors to Proceed With Caution When Buying These Corporate Bonds

According to Wells Fargo Investment Institute, investors today need to be more careful when considering lower-rated investment-grade bonds, particularly BBB-rated corporate bonds. These bonds, which once attracted considerable investor attention due to their balance of yield and quality, are now facing growing pressures that demand greater caution.

‍

In the past, BBB-rated companies were appealing because they offered higher yields than their A-rated peers without requiring investors to sacrifice too much in terms of credit quality. These companies also typically had strong interest coverage ratios, a key measure of a firm’s ability to meet interest payments on its outstanding debt. However, this favorable situation has shifted.

‍

Eric Jasso, a taxable analyst at Wells Fargo, explained in a recent note that the period of strong interest coverage in BBB-rated bonds has now ended. The key reason is that many companies financed their debt at ultra-low interest rates during the pandemic, but as those loans mature, they now face higher refinancing costs due to today’s elevated interest rate environment. As a result, companies’ ability to comfortably cover their interest payments has eroded.

‍

Jasso warned that investors need to “exercise caution” when approaching this segment of the bond market. He pointed out that across nearly every sector, BBB-rated corporate debt has seen interest coverage ratios fall meaningfully below long-term averages, despite many companies experiencing solid earnings growth in 2024. The rapid increase in interest expenses has essentially eaten away at the financial cushion these companies once enjoyed.

‍

Investment-grade corporate bonds are rated from AAA to BBB- by Standard & Poor’s, while Moody’s rates them from Aaa to Baa3. Generally, as credit ratings decline, yields rise, providing investors with greater compensation for taking on more risk. For example, the iShares BBB Rated Corporate Bond ETF (LQDB) currently offers a 30-day SEC yield of 5.33%, while the iShares Aaa-A Rated Corporate Bond ETF (QLTA) offers a slightly lower 4.94% 30-day SEC yield. Both funds have an expense ratio of 0.15%.

‍

Historically, most investment-grade companies have been disciplined about protecting their credit quality. This typically meant scaling back on shareholder rewards like dividends or stock buybacks, as well as reducing capital expenditures, whenever financial pressures threatened to strain their balance sheets.

‍

However, Jasso cautioned that some issuers could begin to feel longer-term credit pressures as their capital intensity increases and profitability declines. This is particularly true for cyclical industries that are more exposed to shifts in global trade policies and evolving regulatory environments.

‍

“Given expected macroeconomic headwinds, pressured metrics, and rich valuations among BBB-rated issuers, we recommend investors exercise selectivity when investing in lower-rated investment-grade credit,” Jasso said.

‍

Among the sectors most affected by trade policy uncertainties are automotive, industrials, and consumer discretionary companies, Jasso noted. While these sectors may appear cheap compared to other investment-grade areas, investors should remain cautious, as underlying risks could lead to longer-term credit deterioration.

‍

Instead, Jasso favors issuers within the financial, telecommunications, and healthcare sectors. These sectors tend to have healthier balance sheets, a strong history of navigating past economic cycles, and are often more insulated from the ups and downs of tariff policies and trade disputes.

‍

Companies in these areas are seen as better positioned to handle the current environment of higher borrowing costs and broader economic uncertainty.

‍

Overall, the Wells Fargo Investment Institute’s message is clear: investors can no longer take a broad-brush approach to BBB-rated bonds. While these bonds have historically provided attractive yields without excessive risk, the changing macroeconomic backdrop means that credit quality is increasingly under pressure.

‍

The combination of rising interest costs, potential profitability challenges, and sector-specific risks makes it critical for investors to be selective and discerning in their allocations.

‍

By focusing on sectors and issuers with stronger financials and a proven ability to weather economic shifts, investors can better position themselves to navigate the challenges ahead while still capturing the potential benefits that come with investing in lower-rated investment-grade corporate debt.
