Stablecoin Flow Analysis

Overview

Track stablecoin supply changes, exchange reserve movements, and on-chain velocity to gauge crypto market capital flows. Stablecoins (USDT, USDC, DAI, etc.) are the "dry powder" of crypto — minting signals new capital entering, burning signals capital leaving, and exchange reserve changes reveal buying/selling intent.

Core Concepts

1. Stablecoin Supply as Market Indicator

Total stablecoin market cap is the single best proxy for crypto market liquidity.

# Stablecoin supply growth → crypto market liquidity expansion
# Historical correlation: BTC price and total stablecoin supply r > 0.85

stablecoin_supply = {
    "USDT": 140_000_000_000,    # ~$140B (dominant, ~65% share)
    "USDC": 45_000_000_000,     # ~$45B (~20% share)
    "DAI": 5_000_000_000,       # ~$5B (decentralized)
    "FDUSD": 3_000_000_000,     # ~$3B (Binance ecosystem)
    "USDS": 2_000_000_000,      # ~$2B (Sky/MakerDAO)
}
total = sum(stablecoin_supply.values())
