TEYMUR Index

A GDP-weighted measure of world money. Every currency is priced in TYMR (sign ), a synthetic unit pinned at 1 USD = 1 TYMR on 3 January 2005 and carried forward by the rates of 29 member economies — so the question "did the dollar fall, or did the lira rise?" gets one neutral answer.

Notes to the report

  1. Official values are computed once per TARGET business day from central-bank reference rates (ECB and national sources), weighted by nominal GDP (IMF WEO, point-in-time vintages). Once published they are never recomputed — later data revisions affect later days only.
  2. Live is a 10-minute indicator from market rates under the last official regime (same weights, same chain constant). It may differ from Official by a few basis points by construction; trend readings are computed on Live. Live market data provided by Twelve Data.
  3. Weights are the current vintage's normalized GDP shares. Membership follows a written rule: entry at ≥0.40% of world GDP, exit after two consecutive vintages below 0.30%, single exchange-rate regime required. Membership history and documented data windows are listed below.
  4. Every official day is verifiable from its inputs; the full recipe is in the TEYMUR methodology. Select a currency for its own page and full history.
  5. Live-only reference series (gold, silver, bitcoin) are published on teymur.com.
