Modeled on the historic yield spike breaking through the 5% threshold driven by oil-price inflation persistence, ballooning Treasury debt auction supply, and higher-for-longer Federal Reserve terminal rate pressures.

When 10-year yields sustain above 5.00%, annual net federal interest expense jumps to $1.16 Trillion. This approaches and eclipses the annual defense allocation ($880B), creating a self-reinforcing fiscal spiral where debt service forces greater Treasury issuance.
Historical context: In October 2023, the 10-year yield touched 5.02% for the first time in 16 years, temporarily halting market momentum until Treasury reduced auction sizing in the Quarterly Refunding Announcement (QRA).
