The BTC Index (BTCX) is a privately developed composite financial index that measures the value of Bitcoin relative to a weighted basket of macro-economic indicators and asset prices.[1] BTCX is an unofficial benchmark with no government or regulatory status, conceptually analogous to the U.S. Dollar Index (DXY), which the U.S. Federal Reserve introduced in 1973 and which is now maintained by ICE Futures U.S.[2]
The index started at 100.00 on 7 March 2025, the day U.S. President Donald Trump signed the executive order ‘‘Establishing the Strategic Bitcoin Reserve and U.S. Digital Asset Stockpile’’.[3] Commentary in financial media characterised the order—which moved roughly 200,000 BTC seized by U.S. authorities into a permanent government reserve—as a watershed moment that recognised Bitcoin as a sovereign reserve asset. BTCX’s creators adopted that date as the index’s base to align its time-series with the policy change.
Methodology
[edit]BTCX is calculated continuously from live quotations supplied by Yahoo Finance. The index is defined as a weighted geometric mean:
The scaling constant 71.336 makes the index equal 100 on its base date.
Component weights
[edit]| Component | Exponent | Interpretation (inverse relationship) |
|---|---|---|
| DXY – U.S. Dollar Index | −0.40 | Bitcoin versus broad U.S. dollar strength |
| ETH/BTC – Ether price in BTC | −0.20 | Bitcoin dominance versus major alt-coins |
| XAU/BTC – Gold price in BTC | −0.10 | Bitcoin versus gold as a store of value |
| SPX/BTC – S&P 500 in BTC | −0.15 | Bitcoin versus large-cap U.S. equities |
| USRE/BTC – U.S. real-estate index in BTC | −0.05 | Bitcoin versus real-estate valuations |
| OIL/BTC – WTI crude oil in BTC | −0.05 | Bitcoin versus global energy prices |
A rise in any component relative to Bitcoin pushes BTCX lower, and vice versa.
Data dissemination
