Why iShares 20+ Year Treasury (TLT) fell 1.83%
iShares 20+ Year Treasury (TLT) fell 1.83% on September 24, 2026 — Yields above 5% pressure long-duration bonds lower.
What happened
10-year Treasury yields broke above 5%, the highest level since 2004, putting direct pressure on long-duration Treasury prices.
Why it moved
Bond prices move inversely to yields; when 10-year rates rise above 5%, the present value of future coupons on long-dated Treasuries (like the 20+ year bonds TLT holds) compresses sharply, forcing mark-to-market losses.
Why it matters
A macro repricing complex: Brent crude above $100 and yields above 5% signal both inflation persistence and tighter financial conditions, hitting long-duration assets hardest.
What would break the thesis
If 10-year yields drop back below 5% — signaling either demand recovery or Fed easing expectations — the duration selloff reverses and TLT recovers.
