US investment grade credit: A buy or a bubble?

The strong economy and market pressure may drive companies to pay down debt

Time to read: 4 min

Recent market stress surrounding trade policy, the US government shutdown, Brexit and recession fears has increased focus on the US investment grade credit market and its sharp rise in leverage in the post-crisis period. Invesco Fixed Income believes these concerns are best analyzed through the lens of the BBB-rated portion of the US investment grade bond market. Some investors worry that this segment is a ticking time bomb set to upend the US fixed income market. Credit spreads on BBB-rated bonds have widened 50 to 100 basis points in the past year.1 With a focus on BBBs, we tackle some important questions for investors: Is the recent sell-off in BBBs a sign of worse things to come, or has the market over-reacted? Are there stabilizing trends on the horizon?

Upward trend in leverage may reverse in 2019

Debt levels among US corporations have grown in the post-financial crisis period in response to a lack of organic growth, low interest rates, modest credit spreads and tax policy that restricted the use of overseas retained earnings. As such, companies have used incremental debt primarily to buy back stock, fund mergers and acquisitions, and increase shareholder dividends. This shareholder-friendly activity has, however, come at the expense of company credit profiles and has exposed the market to potential credit transition risks, in our view.

Going forward, we believe there are several reasons to expect a reversal in this leveraging trend, including a return to organic growth, higher interest rates, wider credit spreads and repatriation of foreign profits. As such, we expect to see less opportunistic funding as acquisition break-even points are higher and companies have increased access to internal capital. Companies are also experiencing increased investor scrutiny over elevated leverage profiles and are beginning to address their balance sheets more proactively. We expect CEOs to highlight their debt reduction efforts in much greater detail during future earnings calls. We also note that large companies have begun linking deleveraging success to CEO compensation. We believe these are very positive trends for investors in corporate credit.

Fed has credit growth in its sights

In addition, we believe issuers and investors have taken note of comments from the US Federal Reserve (the Fed) in its November 2018 Financial Stability Report, which highlighted concerns over the pace of credit growth, leverage and underwriting practices in the leveraged loan market.

The Financial Stability Report also highlighted that the distribution of ratings among investment grade corporate bonds has deteriorated, with a near-record number of bonds rated at the lowest investment grade. As of the second quarter of 2018, 35% of corporate bonds outstanding were at this level, amounting to approximately $2.25 trillion.2 The Fed noted that during an economic downturn, widespread downgrades of these bonds to speculative-grade ratings could force some investors to sell them rapidly, pressuring liquidity and prices in this segment of the corporate bond market.

Ultimately, The Fed noted that despite elevated leverage, low interest rates have kept debt service costs at the low end of their historical range, allowing corporate credit performance to remain favorable. In addition, we estimate that current market spreads cover reasonable estimates of investment grade defaults by multiple times.

US investment grade outlook

We at Invesco Fixed Income believe that risks in BBB-rated credit will likely remain idiosyncratic, as most large bond issuers generate substantial free cash flow to service debt. Furthermore, we do not believe recent global macroeconomic issues (such as trade disputes) will cause a recession.

We have seen this leverage cycle playbook before with the energy crisis of 2015 and 2016. Some companies substantially cut dividends to conserve cash to pay down debt. Others stopped share buybacks, reduced capital expenditures or even went so far as to raise equity to pay down debt. Once companies started to address their balance sheet concerns, their stock prices typically began to stabilize and eventually turned higher. We believe this process could play out again with the majority of BBB-rated issuers. We think the message to CEOs is clear — the time to start fixing balance sheets is now.

BBB outlook

In our view, the largest BBB-rated companies have the cash flow to support their debt and debt service obligations and are beginning to acknowledge market concern about leverage. We believe issuers will begin to pay down debt while the economy is still strong. The recent spotlight on BBBs and punishment of over-levered companies by the equity market is likely to be a major catalyst for balance sheet cleanup. In addition, 2019 earnings growth, which we forecast in the high-single digit range, will likely remain a supportive factor for credit quality. We suspect the recognition of this dynamic could result in corporate deleveraging and outperformance of BBB-rated credits in 2019.

Important information

Blog header image: Marc Sendra Martorell/

Fixed-income investments are subject to credit risk of the issuer and the effects of changing interest rates. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise and vice versa. An issuer may be unable to meet interest and/or principal payments, thereby causing its instruments to decrease in value and lowering the issuer’s credit rating.

An investment grade bond is generally recognized as such if its credit rating is BBB- or higher (Standard & Poor’s) or Baa3 or higher (Moody’s). These bonds are judged by the rating agencies as likely to meet the associated payment obligations.

Financial leverage refers to the use of debt to acquire additional assets.

A basis point is one hundredth of a percentage point.

Credit spread is the difference in yield between bonds of similar maturity but with different credit quality.

Free cash flow is a measure of financial performance calculated as operating cash flow minus capital expenditures.
