Quick Definition

An ETF that invests in a portfolio of bonds, providing diversified fixed-income exposure with the trading flexibility of a stock.

What Is Bond ETF?

A bond ETF holds a portfolio of bonds and trades on stock exchanges like a regular ETF. These funds provide access to fixed-income markets — government, corporate, municipal, or international bonds — with lower minimums and better liquidity than buying individual bonds.

Key Concepts:

  • Duration — sensitivity to interest rate changes (longer = more volatile)
  • Credit quality — investment grade vs high yield
  • Yield to maturity — expected annual return if held to maturity
  • Interest rate risk — when rates rise, bond prices fall

Important Difference from Individual Bonds: Bond ETFs never "mature" — they continuously roll expiring bonds into new ones. This means you don't get the par value certainty of holding a single bond to maturity. (Target maturity bond ETFs like iBonds are an exception.)
