Haven reconstructs multiple SPX and SPXW box spreads from single-leg option marks, removes unreliable observations, takes the median financing rate at each expiration, and interpolates those rates into standardized constant maturities. The published history runs from January 3, 2012 through October 13, 2026, including October 7 from that day's closing marks. A session with no defensible estimate is omitted. These figures are an indicative reference, not a complex-order-book quote and not the price at which a financing order executes.
The Haven SPX Box Rate is not a Truth in Lending APR, not a commitment to lend, and it excludes Haven Funding LLC advisory fees. Borrowing against securities can involve margin calls and liquidation of collateral.
