How companies issue bonds, and what a credit rating actually costs them in real yield
Finance 101 covered how bonds are priced once they trade. This chapter covers how a bond actually gets issued in the first place — the DCM process — and the very real, quantifiable cost of a company's credit rating.
The bond issuance process
Similar shape to an IPO, adapted for debt: the company (the "issuer") mandates a bank or syndicate of banks, credit rating agencies assess and assign a rating (see below), the deal is marketed to fixed-income investors (often over a much shorter timeline than an equity roadshow — sometimes just a day or two for a well-known issuer), an order book is built, and the bond is priced — typically expressed as a spread over a benchmark (a government bond of similar maturity) rather than an absolute yield, directly connecting to Finance 101's credit-spread concept.
Investment grade vs. high yield issuance — genuinely different processes
An investment-grade (IG) issuer (strong credit rating, BBB-/Baa3 or higher) can often price and issue a bond within a single day, with a large, deep pool of investors willing to buy relatively quickly at a modest spread. A high-yield (HY) issuer typically needs a longer, more intensive marketing process — investors demand more scrutiny and a materially wider spread to compensate for real default risk, exactly Finance 101's IG-vs-HY distinction, now seen from the issuer's side of the table instead of the investor's.
The real cost of a credit rating downgrade
Worked example: a company issues $500M of 10-year bonds. As an A-rated issuer, it prices at a spread of 100 basis points (1.00%) over the 10-year government benchmark, which is trading at 4.00% — all-in coupon = 4.00% + 1.00% = 5.00%. Annual interest cost = 5.00% × $500M = $25M/year.
If the same company were rated BBB (still investment grade, but lower) instead, it might price at a 180bp spread instead of 100bp: all-in coupon = 4.00% + 1.80% = 5.80%. Annual interest cost = 5.80% × $500M = $29M/year — $4M more per year, or $40M over the bond's 10-year life, purely from a lower credit rating. This is exactly why companies (and their DCM bankers and treasury teams) actively manage credit ratings as a real financial decision, not just a label — the rating has a direct, compounding cash cost.
Covenants — the DCM equivalent of a merger agreement's fine print
Just as Finance 101's M&A deep dive covered break fees and MAC clauses as the real fine print of a merger agreement, a bond's indenture contains covenants — contractual restrictions on the issuer, such as limits on how much additional debt it can take on, restrictions on asset sales, or minimum financial ratios it must maintain. Covenant-lite issuance (fewer, weaker restrictions) became notably more common in parts of the leveraged finance market in recent cycles — a real, structural shift in how much protection lenders actually retain, worth knowing exists even without a specific current data point to cite.
Syndication — spreading the risk
For a large bond deal, a single bank rarely underwrites the whole issuance alone — a syndicate of banks jointly underwrites and distributes it, sharing both the fee and the risk that the bonds don't sell as expected. This mirrors the equity syndicate structure from the ECM chapter, applied to debt instead.

Check your understanding
1. Why is a corporate bond's yield typically quoted as a spread over a benchmark, rather than a standalone number?
2. A company's rating moves from A to BBB, widening its spread from 100bp to 180bp on a $500M, 10-year bond, with the benchmark unchanged. What's the approximate extra annual interest cost?
