The TED spread is kind of like the Paul Revere of the financial markets. Just as Paul Revere was tasked with warning the American colonists of the British invasion, the TED spread is tasked with warning investors of potential market downturns and volatility.

TED Spread

Unfortunately, the TED spread is not named for a brilliant economist or a famous investing icon named Ted. The TED spread actually got its name from the two financial instruments is compares—the 3-month Treasury Bill (T-bill) and the eurodollar futures contract. Investors simply took the “T” from T-bill and combined it with “ED,” which is the ticker symbol for the eurodollar futures contract on the Chicago Mercantile Exchange (CME), and they came up with “TED.”

The TED spread measures the difference between the yield on the 3-month Treasury Bill (T-bill) and the value of the eurodollar futures contract—which is based on the 3-month LIBOR rate. To calculate the TED spread, you simply subtract the yield on the 3-month T-bill from the value of the eurodollar contract. For instance if the value of the eurodollar contract is at 3.75 percent and the yield on the 3-month T-bill is at 2.25 percent, the TED spread is 1.50 percent, or 150 basis points (3.75 – 2.25 = 1.50).

What Does the TED Spread Tell Us?

When the TED spread is

increasing

, it tells us either that banks believe the other banks they are lending to have a

higher

risk of defaulting on the loans so they are charging a

higher

interest rate to offset this risk or that investors are flocking to buy T-bills because they believe the stock market is faltering. It also tells us that the credit markets are not functioning as smoothly as they could be—which is sign of potential economic contraction.
