Stablecoin flow analysis tracks the movement of USDT, USDC, DAI and FDUSD between exchange wallets and the broader on-chain ecosystem. Glassnode and CryptoQuant both publish the canonical inflow/outflow series. The signal works on a 1-2 week lead time: stablecoin inflows to exchanges precede BTC buying pressure; outflows precede selling pressure or DeFi deployment.
The 2024-2025 period saw structural stablecoin growth from $130B to $180B in total market cap. CoinDesk and Bloomberg Crypto both covered the expansion as a sign of deepening crypto-dollar liquidity. The USDT share remained around 70% throughout the period; USDC recovered from its March 2023 depeg trauma to reclaim roughly 25% share.
Tron versus Ethereum USDT supply tells different stories. Tron USDT (cheap, fast, Asian retail dominant) grew faster than Ethereum USDT through 2024-2025, reflecting Asian retail and remittance demand. DefiLlama's chain-by-chain breakdown is the cleanest free source for this view.
For trading signals, the practical rule is: 30-day net stablecoin issuance above +$5B is a structurally bullish read for risk assets including BTC. Below -$3B is structurally bearish. The 2022-Q1 setup, where stablecoin market cap was near peak but net flow had turned negative, was the early warning that the May 2022 Terra collapse later confirmed. The Block flagged this in real-time at the time.
