Keeping an Eye on Heavy Corporate Debt

The opportunity to borrow at low interest rates has enticed corporations to issue more than $1.0 trillion in bonds every year since 2010. By the end of 2018, corporate balance sheets were carrying $9.1 trillion in debt, up from $5.5 trillion in 2008.1 As a result, corporate leverage amounts to about 46% of U.S. gross domestic product (GDP), matching levels reached during the last financial crisis.2

Whereas Treasuries are guaranteed by the federal government as to the timely payment of principal and interest, corporate bonds are not guaranteed and depend on the financial strength of the issuing company.

Most corporate bonds are evaluated for credit quality by one or more ratings agencies, each of which assigns a rating based on its assessment of the issuer’s ability to pay the interest and principal as scheduled.

Bond investors generally expect a higher interest rate as compensation for bearing the additional risk.

Many factors can alter a company’s perceived credit risk, including shifts in economic or market conditions, adjustments to taxes or regulations, a
