Stock Lending Program (SLIP) & Cash Sweeps APY Monitor

Overview

RealizeAlpha provides complete visibility into passive yield generation across account assets through the Stock Lending Program (SLIP) Dashboard & Cash Sweeps APY Monitor. Traders can track shares loaned to institutional borrowers, review historical yield payouts, verify 102% cash collateral protections, check program agreement eligibility, and monitor multi-tier high-yield cash sweep interest rates (Gold vs. Standard APY) backed by FDIC partner banks.

Key Capabilities

1. Securities Lending Income Program (SLIP)

Automated Yield Tracking: Robinhood’s Fully Paid Securities Lending Program borrows fully paid equities from participating accounts and lends them to institutional counterparties.
102% Cash Collateral Protection: While shares are out on loan, cash collateral equal to at least 102% of the shares’ market value is placed in custody at a third-party bank to protect the owner against borrower default.
Unrestricted Trading Freedom: Users retain 100% economic ownership and can sell loaned securities at any time without waiting for loans to be recalled or settled.
Dividend Equivalents (Cash-in-Lieu): If a loaned security pays a dividend, the user receives manufactured payments equal to 100% of the dividend value.
Payment History Ledger: Monthly and periodic payouts with itemized line items showing symbol, quantity loaned, annualized borrow rate, collateral backing, and interest earned.

2. High-Yield Cash Sweeps & APY Rate Monitor

Multi-Tier Rate Monitoring: Real-time visibility into current effective APY, Robinhood Gold rate (e.g., 5.00% APY), Standard rate (e.g., 1.50% APY), and promotional boost rates.
FDIC Insurance Network: Tracks uninvested cash swept into partner banks, providing up to $2,250,000 in aggregate FDIC insurance coverage.
Interactive Yield Calculator: Dynamic simulator estimating monthly and annual passive cash income based on slider-selected cash reserves.
Partner Banks Directory: Comprehensive list of FDIC-insured network banks (Citibank, Goldman Sachs Bank USA, Wells Fargo, JPMorgan Chase, etc.).
