The historical echo
Credit moved first in 2007—and during the late-1990s market cycle.
Federal Reserve materials from August 2007 recorded widening investment-grade, high-yield, and global CDS spreads as mortgage conditions deteriorated. A CME review of the 1990s and 2003–2007 bull markets likewise found that credit spreads began widening before equities reached their peaks.
That sequence gives this report its relevance: stress can become visible in the cost of money before it becomes obvious in stock prices or the economy. It is an invitation to pay attention—not a declaration that a crash date has been identified.
