How To Read It

  • TLT is a bond-price ETF proxy, so it generally moves opposite long-term yields and is not itself a yield chart.
  • Because the fund owns long-duration bonds, changes in inflation expectations, real yields, and term premium can drive large price swings.
  • Pair it with the 10-year yield and full Treasury curve board to see which part of the rates backdrop is driving the move.
