Has the yield curve inverted in the last year? Yes: 2Y−3M below zero in 5 of 12 months, 10Y−2Y in none

Each line is the gap between what the U.S. government pays to borrow long-term and what it pays short-term. When a line drops below zero, short-term borrowing costs more than long-term, the pattern that has run ahead of most U.S. recessions. The last 12 month-end readings show whether that pressure is easing or deepening.

How have the two scores moved this year? Funding pressure unchanged at 90, risk appetite down 7 to 53 (12 months to Oct 2026)

Month-end readings from the archive, so the latest figure here is the last completed month rather than this week’s score above.

Common mistake then
Hired enterprise sales ahead of a fourth-quarter rebound that did not come, as enterprise buying cycles lengthened.
What held up then
Moved to annual contracts paid up front, with a 15% discount for doing so; turned open engineering roles into 6-month contract-to-hire positions.
What marked the turn
The recession warning gauge climbing back above +0.25%, with funding pressure falling two months in a row, marked the safe time to expand again.
Which habits from the zero-rate years still shape your company? Infrastructure, support, data, pricing, org chart, and roadmap

The Fossil Record · What a product's shape says about the money it was built with

With money this expensive, it is worth checking whether any of these still shape your budget.

AreaBuilt when money was cheapBuilt when money was expensiveWhy
InfrastructureMicroservices sprawl and heavy coordinationConsolidated monoliths and fewer moving parts“Coordination tax is a headcount tax. Cheap money pays for it; expensive money forces simplification.”
SupportLive chat, phone support, and concierge workflowsSelf-serve help centers and AI deflection“In growth climates, users are assets to retain. In tight climates, support is a cost to control.”
