Credit Spreads, Explained: The Fear Gauge for Lending

Foundations

A credit spread is the extra yield a borrower pays above the government rate for the same maturity. If the 10-year Treasury yields 4.5 per cent and a company’s 10-year bond yields 6.5 per cent, the spread is 200 basis points: the market’s price for the risk that the company fails to pay. Spreads are the bond market’s fear gauge for lending, and they often smell trouble before equities do.

How to read the number

Spreads are quoted in basis points (hundredths of a percentage point) over the government curve. Investment-grade companies might pay 80 to 150 over; high-yield (junk) borrowers several hundred. The level prices expected defaults plus a premium for uncertainty and illiquidity. The MOVE in spreads is the signal: widening means lenders are demanding more compensation (fear rising), tightening means confidence returning. Because spreads aggregate the views of the people actually owed the money, they are treated as the adult in the room.

Spreads versus equities

Credit and equity look at the same companies from different seats. Shareholders own the upside; bondholders own a fixed claim and think only about downside. That makes credit inherently sceptical, and divergences informative: equities rallying while spreads widen is a classic warning that risk is being repriced where the money is lent, not where the stories are told. In 2007-08, spreads deteriorated well before stockmarkets accepted what was coming.

Where spreads bite the real economy

Spreads are not just a signal; they are the cost of capital. Wide spreads shut companies out of refinancing, force private credit borrowers to pay in kind, and turn maturing debt into a cliff. Whole cycles turn on this plumbing: a “credit crunch” is spreads gapping wider until borrowing stops making sense. When our private credit coverage tracks stress, spreads are the public-market shadow of what the private books are hiding.
