SBLOC vs Margin Rate Arbitrage

Compare pledged-asset lines against margin — arbitrage 200–400 bps.

Overview

Securities-Based Lines of Credit (SBLOC) at private banks often price 200–400 bps below regulated margin loans, with more permissive maintenance requirements and no forced-liquidation triggers on standard volatility. Actively arbitrage: move borrowings from margin to SBLOC, or spread across brokers for the best coupon. Distinct from buy-borrow-die — this is pure cost-of-capital optimization on existing debt.
