What it costs, right now, to move USD into and back out of the stablecoins the crypto
venues quote in — and how much can be moved before the book runs out. Use for "what does
USDT conversion cost", "is USDC or USDT cheaper to hold", "how much can I convert at once",
"what is the USDT basis".
No coin involved: this is the currency leg on its own. Returns per-market cost in and out,
the cheapest venue for each direction, aggregate capacity, and how far each stablecoin is
trading from 1.0000.
where_to_convert IS THE ACTIONABLE PART: the cheapest and dearest conversion venue and
the bp/USD penalty between them. Measured at 13.5x-17x on USDT and 27.7x on USDC, and the
winner ROTATES with size because these books are shallow enough that the usual winner runs
out — Kraken wins to $2.5M and loses to Bitfinex at $5M.
CAPACITY IS THE PART THAT SURPRISES PEOPLE. The USD/stablecoin books are thin relative to
the coin books they feed, so a size that walks a coin book comfortably can exhaust the
currency book outright. size_exceeds_capacity is a hard wall, not a cost.
par_offset_bp is NOT charged as a cost — a desk that buys and later sells the same
stablecoin is flat to it. Do not add it to the round-trip figure.
notional_usd = the size to price. Requires an EnsoTrade Pro API key.
