Balance-Transfer to Investment Arbitrage

3% BT fee for 18mo = ~2% APR — arbitrage vs 5% T-bill / private lending yield.

Overview

A typical 0% balance transfer costs a 3% one-time fee for 15–21 months of money — an effective APR of ~2%. Park the proceeds in T-bills, high-yield MMFs, brokered CDs, or short-duration private notes at 5%+. Net 200–300 bps risk-free-ish spread on borrowed capital. Requires flawless payoff discipline and a plan to refinance the balance before the promo ends.
