Regime Evidence Builds in Layers
A regime conclusion should become stronger only as independent evidence progresses from observation to confirmation and transmission.

Match the Dollar Regime to Time Horizon and Invalidation
A regime interpretation should state its time horizon and the evidence that would make the interpretation weaker or wrong.
What it is
Intraday moves can reflect positioning and events, multiweek moves can reflect policy repricing and relative growth, and structural moves can reflect productivity, fiscal credibility, external balances and reserve behavior.
Why it matters
Mixing horizons creates false certainty, while explicit invalidation conditions make the framework updateable as new evidence arrives.
Example
A stress interpretation should lose confidence if Broad USD fails to confirm, real yields reverse, credit and volatility normalize, or funding remains stable.
Common mistake
Using one-day evidence to make a structural claim or refusing to revise a regime label when confirming signals reverse.
What to watch
- time horizon
- Broad USD
- real yields
- credit spreads
- volatility
- funding conditions
Key takeaway
State both the horizon and the invalidation evidence before treating a regime view as durable.
