The yield curve is a popular tool that is used to try to forecast the direction of the economy. More often than not, people talk about how a flat or inverted yield curve is bad for markets. I choose to analyze the movement of the curve rather than its static shape. Historically, a rapidly steepening curve has actually been more detrimental for stocks than a flat or inverted curve. In a steepening yield curve, short-term rates fall faster than long-term rates. In the past, steepening yield curves have been associated with the Federal Reserve quickly lowering the Federal Funds Rate during a recession.

The difference between the interest rate of a high yield bond and a Treasury of comparable maturity is called a high yield spread. The narrower the spread, the more optimistic investors are about the probability of risky U.S. corporations being able to cover their interest payments and eventually pay off their debts. When investors grow more uncertain, they’ll demand a higher rate on high yield bonds and cause spreads to widen.

The TED spread is frequently cited as a measure of credit risk in the overall economy. The spread reflects the difference between two short-term interest rates: 3-month USD LIBOR and the 3-month U.S. Treasury yield. LIBOR reflects the rate at which banks borrow between each other on an unsecured basis. The perceived risk in the banking sector grows as the spread between LIBOR and T-bills widens out.
