Back to Basics: Spread

Back to Basics: Spread

In finance, a spread is the difference between two related prices, interest rates, or yields. It’s a simple concept that shows the gap between what one party pays and what another receives.

One common example is the bid-ask spread in stock trading. The bid is the highest price a buyer is willing to pay, while the ask is the lowest price a seller will accept. The difference between them is the spread. A narrow spread usually means there’s high trading activity (liquidity), while a wider spread could mean fewer trades or more risk.

Another example is the yield spread between government and corporate bonds. If a corporate bond offers a higher yield than a Treasury bond, that extra yield—the spread—compensates investors for taking on more risk.

Spreads are also used to understand credit risk and funding conditions. One well-known measure used to be the LIBOR-OIS spread, which tracked bank credit risk. However, LIBOR has been phased out. Today, markets use SOFR (Secured Overnight Financing Rate) instead.

  • SOFR-OIS Spread: Reflects market expectations of Federal Reserve policy and overnight funding health.
  • SOFR-Treasury Spread: Shows credit and liquidity risk in the market.
  • SOFR–Repo Spread: Measures the premium for borrowing cash using Treasuries as collateral.
  • SOFR Basis Swaps: Help compare different types of SOFR or SOFR with other rates.
  • Credit Spread Adjustments (CSAs): Adjust SOFR-based loan rates to reflect borrower credit risk.

Why it matters: Spreads give important clues about market sentiment, risk levels, and liquidity. Whether you’re trading stocks, analyzing bonds, or studying interest rates, understanding spreads can help you make smarter financial decisions.
