How 20Y+ Treasury (TLT) Responds

Bonds rally on housing-led economic weakness.

Scenario Background

Housing starts measure new residential construction beginnings (single-family and multi-family). The series captures the earliest stage of the housing cycle: builder decisions to commit capital to new construction. A collapse below 1.1M annualized starts represents severe housing weakness, signaling that builders are responding to demand destruction, high financing costs, or inventory overhang.

Historical Context

Housing starts peaked at 2.3M annualized in January 2006 before collapsing to 478k by April 2009 during the housing crisis. Post-2009, starts gradually recovered to 1.8M by early 2022 before declining to 1.3M in 2023-2024 amid rate stress. The 2020 COVID shock produced a brief dip to 900k before rebounding. The post-2008 "housing gap" (persistently low starts vs. household formation) contributed to the 2020-2022 housing shortage and price explosion.

What to Watch For

  • Housing starts below 1.0M sustained
  • Building permits declining faster than starts
  • NAHB Builder Confidence below 30
  • New home sales declining below 500k
  • Construction employment YoY turning negative
