What is a crypto cash-and-carry basis trade?

A cash-and-carry basis trade is a delta-neutral strategy where an institutional investor buys spot cryptocurrency (e.g. BTC or ETH) and simultaneously sells an equal notional amount of dated futures contracts trading at a premium (contango), locking in a risk-free annualized spread at expiration.

How does perpetual funding rate arbitrage differ from calendar futures?

Unlike calendar futures which expire on a set date and converge to spot automatically, perpetual contracts never expire. Instead, long and short traders exchange periodic funding payments (typically every 8 hours) to anchor the contract to spot price. An investor can hold long spot and short perps to collect positive funding rates.

What are the primary risks of a crypto basis trade?

The core risks are counterparty exchange default, execution slippage, negative funding rates (where short perps must pay longs during market downturns), borrowing rate spikes on leveraged capital, and liquidation risk on the short derivative leg during extreme upward volatility.

Risk & Microstructure Safeguards

Contango vs. Backwardation: In contango ($F > S$), the basis trade locks in a deterministic positive spread. If backwardation occurs ($F < S$), shorting futures locks in a guaranteed loss unless held for reverse cash-and-carry.
Perpetual Variable Funding Risk: While perpetual funding yields can reach 20%+ in bull markets, funding rates fluctuate every 8 hours. During extended market drawdowns, funding rates can flip negative, forcing short traders to pay longs.

Quantitative Formulation & Microstructure Calculus

The annualized basis yield is computed by scaling the percentage spread between dated futures and spot prices across the year:

Annualized Gross Basis = ((Futures Price - Spot Price) / Spot Price) × (365 / Days to Expiry) × 100%
Net Annualized Basis = Gross Basis - (Financing Cost + (Slippage × 365 / Days to Expiry))
Annualized Perpetual Funding = 8-Hour Funding Rate × 3 payments/day × 365 days

On high-throughput Layer 1 order books such as Hyperliquid, the funding rate is calculated by measuring the median premium of the order book's mid-price over the external spot oracle index over each 8-hour window, clamped between maximum caps to prevent manipulative spikes.
