Duration in plain terms

HELIOS-first, not HELIOS-only
Rates dominate, but sentiment and geopolitical spikes can move Treasuries for non-Fed reasons — the Panel keeps those channels visible.
GLD vs. IEF scenarios
Both can rally in panic; they diverge when growth and real-rate stories split — compare intentionally.
Term premium and curve shape (educational)
Steepening vs. flattening carries different macro stories; use structured research, not a single headline.
