How this service works
Deribit BTC or ETH futures term structure: each expiry's price, premium over the index and annualized basis, plus the perpetual's premium. Use for cash-and-carry yields or sentiment.
Output
A term structure table for BTC or ETH listing each Deribit futures expiry with its price, premium over the spot index in dollar and percentage terms, and annualized basis rate; plus the perpetual contract's current premium. Useful for evaluating carry trade yields and reading market sentiment.
Example use cases
Cash-and-carry yield screening
“Show me the annualized basis for BTC futures across all Deribit expiries so I can find the best cash-and-carry trade opportunity right now.”
ETH market sentiment check
“Is the ETH futures market currently in contango or backwardation on Deribit? Pull the term structure and tell me what sentiment it implies.”
Perpetual vs spot premium monitor
“What's the current BTC perpetual's premium over the spot index on Deribit, and how does it compare to the fixed-expiry futures basis?”
