What it means
Before Milken, companies with lower credit ratings had little access to bond markets and relied mainly on banks. Milken argued that a diversified collection of lower-rated bonds paid enough extra interest to compensate for the higher chance of default.
He built a trading and sales operation that proved the point and attracted large investors. This created a new source of funding for growing companies, including many in telecommunications, media and retail.
It also made leveraged buyouts possible on a larger scale, because buyers could borrow heavily against the target's assets and cash flow. Leveraged buyouts are takeovers financed mostly with debt.
The approach had critics. Some argued the market encouraged excessive borrowing, hostile takeovers and short-term thinking.
Others said it democratised credit and gave smaller firms the chance to grow. In 1990 Milken pleaded guilty to securities and reporting violations, paid substantial fines, and was barred from the securities industry.
His former firm, Drexel Burnham Lambert, had already collapsed into bankruptcy earlier that year. The episode is often used to teach how fast-growing financial innovations can outpace oversight.
After his legal troubles he focused on medical research funding and education through the Milken Institute and related organisations. For non-finance readers, the story is a useful reminder that high-yield debt is a legitimate asset class, but that incentives and rules matter greatly in how it is sold.
Today the market he helped create is a normal part of corporate finance. Companies of many kinds issue high-yield bonds, rating agencies classify them, and funds hold them for income.
When you hear a colleague mention a company's bonds trading at a wide spread to government debt, the ideas behind that conversation trace back to this period.
In practice
Real-world examples.
Example
A mid-sized cable company needs $200,000,000 to build out its network but cannot qualify for investment-grade ratings. Its bankers arrange a high-yield bond issue paying a higher interest rate than safer bonds. The company gets the money it needs, and investors accept the added risk for the extra income.
Example
A pension fund analyst studies why high-yield bonds yield more than government bonds. She uses the history of the market's growth to explain that the extra yield compensates for default risk. Her committee decides to hold a small portion of the portfolio in high-yield bonds, spread across many issuers so that no single default does serious damage.
Example
A business school instructor uses the Milken story to teach ethics in finance. Students discuss how innovation, incentives and legal compliance interact. The class debates where creative financing ends and rule-breaking begins. Students leave with a clearer view that compliance is part of the job and not an obstacle to it.
Case study
Seen in the real world.
Redstone Broadcasting is an illustrative, fictional radio group with annual revenue of $90,000,000 and a credit rating too low for ordinary bank loans. The owners want to buy three rival stations for $120,000,000, but banks will lend only $40,000,000.
An investment bank proposes issuing $80,000,000 in high-yield bonds paying 11% interest, which is about 4 percentage points above comparable safer bonds. The extra cost is $3,200,000 a year, but it makes the whole deal possible.
In this illustrative case, the acquisition succeeds and revenue rises to $150,000,000 within four years. The owners credit the high-yield market, the kind of market Milken helped create, for giving them access to capital they could not get elsewhere. The board also keeps a close eye on the risks. Interest of $8,800,000 a year on the bonds (11% of $80,000,000) takes a large share of operating profit, so a downturn in advertising could make payments difficult. The finance team sets a rule that profit must cover interest at least twice, and it monitors that ratio every quarter.
Watch out
Common mistakes.
- Believing that high-yield bonds are worthless, when they are real debt that pays interest and often performs well.
- Assuming the market vanished after the late 1980s, when it grew substantially and is now a regular part of corporate finance.
- Reducing the story to a single scandal and ignoring the innovation in credit markets that followed, which changed how companies of all sizes borrow.
Questions
People also ask.
What are junk bonds?
They are bonds rated below investment grade, which pay higher interest to compensate investors for a greater risk of default, and the more neutral label today is high-yield bonds.
Why did Milken become famous?
He helped build the market that let lower-rated companies raise money through bonds, and later became known for his legal case and for his philanthropy, so his legacy is debated rather than simple.
What did Milken do after his guilty plea?
He focused on philanthropy, particularly medical research and education, through the Milken Institute and related efforts, which supports research and public discussion on economic growth and health.
