Analytical Proof & Invariants

Machine Precision
Governing Mathematical Formula:
Annualized APR (%) = (8-Hour Funding Rate % × 3 funding periods/day) × 365 days

Step-by-Step Mathematical Derivation

1
Daily Funding Multiplier

Perpetuals settle funding every 8 hours (3 times daily). Daily Rate = 0.035% × 3 = 0.105% per day.

2
Annualized Yield Invariant

Annual APR = 0.105% × 365 = 38.325% gross APR.

3
Capital Position Allocation

$50,000 capital is deployed: $25,000 buys physical spot BTC, and $25,000 collaterals a 1x Short BTC Perpetual swap. Price delta is 100% neutralized (0.00 delta).

4
Net Dollar Cash Flow

Short Perp Position ($25,000) collects 38.325% = $9,581.25/year in pure passive funding fees regardless of whether Bitcoin surges to $150k or crashes to $20k.

Frequently Asked Questions

What is Funding Rate Cash and Carry Arbitrage? +
When perpetual swap markets trade at a premium to spot, longs pay shorts funding every 8 hours. By holding spot long and shorting the perp 1x, you eliminate all price risk while collecting continuous funding yields.
What are the primary risks of funding rate arbitrage? +
Execution/slippage risk on entry, exchange counterparty risk (insolvency), funding rates turning negative (requiring position unwinding), and liquidation risk on the short leg during violent upward short-squeezes.
