How 20Y+ Treasury (TLT) Responds
Scenario Background
Shelter CPI measures housing costs (rent and owners' equivalent rent) in the consumer price index. Shelter accounts for roughly 35% of CPI and 42% of core CPI, making it the single largest inflation component. Shelter inflation lags market rent changes by 12 to 18 months due to BLS methodology (rolling 6-month rent surveys).

Shelter CPI peaked at 8.2% YoY in March 2023, the highest since 1982. Private-sector rent measures had already peaked in early 2022 at similar levels, correctly predicting the shelter CPI peak roughly 12 months later. The 2022-2024 cycle saw shelter CPI decline from 8.2% toward 5.5% by early 2024, subtracting roughly 90 bps from core CPI over that period. The 1970s-early-1980s cycle saw shelter CPI above 10% for extended periods, anchoring high inflation expectations.
