Frequently asked SPMB fail to deliver questions

What is the latest SPMB fail-to-deliver count?
As of May 14, 2026, State Street SPDR Portfolio Mortgage Backed Bond ETF (SPMB) fail-to-deliver quantity is 681.3K shares, with a 30-day average of 27.4K shares. The SEC publishes FTD data twice monthly: first-half data at month-end, second-half around the 15th of the following month.
What is the FTD aggregate net balance?
FTD figures represent the aggregate net balance in NSCC's Continuous Net Settlement (CNS) system, not the gross failed-share count. The published numbers run 2-6 weeks stale relative to the underlying settlement date.
How do SPMB FTDs affect options pricing?
Persistent FTDs flag hard-to-borrow conditions that distort put-call parity: in HTB names, synthetic long stock (long call + short put at the same strike) trades below the frictionless-parity price by approximately the borrow rebate. The discount equals the lending revenue forgone by holding the synthetic instead of actual shares. Reg SHO threshold-list inclusion follows from sustained FTD persistence.
