$100 purchasing power · Since 1999
$100$48.89
MACRO / USD REGIME
The U.S. dollar, measured.
One evidence-led view of domestic value, external strength, money growth, reserve role and how much Bitcoin a fixed $100 can buy. Nothing is collapsed into an opaque score.
Reading ruleRead each axis independently: domestic purchasing power can fall while the currency remains firm in FX markets and important in global reserves.

Methodology, freshness and known limitations
Engine rules
- No composite currency score is calculated. Each dimension remains visible and independently sourced.
- Changes use the last observation on or before each horizon. Percentiles compare the latest observation with the full ingested history.
- Selected-range charts include the nearest prior observation when available so the rebase has an auditable anchor.
- Missing or delayed data never defaults to neutral; it is surfaced as Not ingested, Awaiting update, Stale or Unavailable.
