Housing Starts vs 30-Year Mortgage Rate
When mortgage rates rise, housing demand cools and builders pull back. New housing starts have historically responded to mortgage moves with a 6–12 month lag.

- 30Y Mortgage
Housing is the most interest-rate-sensitive sector in the economy. A buyer financing a $400,000 home sees their monthly principal-and-interest payment jump from ~$1,700 at a 3% rate to ~$2,700 at 7% — a 60% increase in carrying cost. Builders see this in their sales pipeline within months and adjust new construction accordingly.
The 2022–23 episode was textbook: the 30-year fixed rate rose from sub-3% in late 2021 to over 7% by late 2022. Housing starts peaked at 1.8 million annualized in April 2022 and fell to 1.3 million by mid-2023 — a 28% drop. The lag was short because builders had backlog they could work through before slowing, but the magnitude was severe.
The pre-2008 cycle was longer and uglier: mortgage rates were already low and starts had run at unsustainable 2 million+ pace. When financing dried up in late 2007, starts crashed 75% over the next 18 months and didn't recover to a normal range until 2015.
Watching the two series together gives a leading view of the housing market. Mortgage rates that have already risen are committed pain still in the pipeline; rates that are falling signal coming activity.

CPI vs PCE
CPI and PCE are the two main U.S. inflation gauges. They usually move together but measure different baskets with different weights — and the gap between them drives where the Fed sets policy.
Core CPI vs Core PCE
Core measures strip out food and energy — the two most volatile CPI and PCE components — to reveal the underlying inflation trend. Core PCE is the Fed's single most-watched inflation gauge.
CPI vs PPI
The Producer Price Index (PPI) measures prices received by domestic producers. Changes in PPI often show up in CPI several months later — making PPI a leading indicator of consumer inflation.
10-Year vs 2-Year Treasury Yield
When 2-year yields exceed 10-year yields the curve is inverted — and inversions have preceded every U.S. recession since 1955. Compare the two benchmark yields directly.
Fed Funds Rate vs 10-Year Treasury Yield
The federal funds rate is the Fed's lever on short-term interest rates; the 10-year Treasury yield is set by the bond market. Comparing them shows the market's read on Fed policy.
30-Year Mortgage vs 10-Year Treasury
The 30-year fixed mortgage rate closely tracks the 10-year Treasury yield plus a spread that reflects credit risk, prepayment risk, and mortgage-backed-security pricing.
