Definition

Stock-to-Flow — existing supply divided by annual new issuance. A scarcity ratio.

Formula

stock_to_flow = total_supply / rolling₃₆₅_sum(daily_issuance_btc)

How we compute it

Annual flow is the trailing-365-day sum of daily issuance (supply diff); S2F divides total mined BTC by it. Clamped to [0, 1000].

Provenance · Every on-chain metric traces back to our own self-hosted Bitcoin archive node — no third-party data vendor sits in the path. We extract the full UTXO lifecycle (each output's creation height/time, value, and the height/time it was later spent), join it against an independent USD price oracle, and roll it up into daily aggregates. The metric formulas are pure functions over those aggregates (src/pipeline/formulas.py), so any value on this page can be reproduced from the published daily archive.

Interpretation

Higher = greater scarcity. Steps up sharply at each halving as flow halves.

Caveats & limitations

·S2F is a controversial price model; we publish the ratio itself, not a price prediction. Treat as a scarcity descriptor, not a forecast.
