The BBB Spread
ICE BofA BBB US Corporate Index Option-Adjusted Spread
The number, plainly.
The extra yield investors demand to hold BBB corporate bonds over Treasuries, the credit-risk premium at the edge of investment grade.
Higher, lower, and what each means.
Widening means the market is charging more for corporate risk; it often moves before stress shows up elsewhere.
A reading is not a verdict. The Scan phase of Woodring’s Loop collects the signal; the Story phase asks what futures it is consistent with, and only the Stake phase turns that into a decision. This page does the first part.
The line in your 2027 plan.
Tests: how much the market is charging for corporate risk, and whether the plan's financing window is still open.
Write the assumption down, name the reading that would break it, and put a date on when it has to be argued again. That is the 18-Month Sunset applied to one line of a budget. The Last Annual Planshows what this season’s moves have already done to the common ones.
