BND vs TLT: Steady Ballast or Aggressive Rate Bet?
BND and TLT serve completely different roles despite both being bond ETFs. BND is the total US bond market (duration ~6.2 years) — a diversified, moderate-risk anchor for portfolios. TLT is concentrated in 20+ year Treasury bonds (duration ~17 years) — essentially a leveraged bet on interest rate direction. TLT can drop 30%+ in rising rate environments but soar when rates fall sharply.
Key Differences
- Duration: BND ~6.2 years, TLT ~17 years — TLT is nearly 3x more sensitive to rate changes
- BND diversifies across Treasuries, corporate, agency, and mortgage-backed bonds; TLT is 100% long Treasuries
- TLT is a crisis hedge: it tends to spike when equities crash (flight to safety effect)
- In rising rate environments (2022-2023), TLT lost ~45% while BND lost ~18%
- BND is a set-and-forget bond allocation; TLT requires active conviction about rate direction

Bottom Line
For a standard bond allocation: BND. For a tactical rate bet or crisis hedge: TLT. Most investors should default to BND unless they have a specific thesis about the rate cycle. TLT's extreme duration makes it unsuitable as a core bond holding.
