T-Bond
Long-term U.S. Treasury debt with 20- or 30-year maturities — the most sensitive to interest rate changes among Treasuries.
Treasury Bonds (T-Bonds) are the long end of the Treasury curve, maturing in 20 or 30 years. They pay semi-annual coupons and carry the highest duration of any standard Treasury security, meaning their prices are most sensitive to yield changes.
The 30-year T-Bond is the instrument most sensitive to long-run inflation expectations and fiscal sustainability concerns. When markets worry about U.S. debt levels or persistent inflation, the 30-year yield rises (bond sell-off) — and that tightening in long-term rates transmits directly to mortgage markets and corporate borrowing costs.
Active traders follow the 30-year for macro signals beyond what the 10-year tells you — it prices in decades of risk, not just the next few Fed cycles.
