Credit Card Arbitrage

Key Takeaways

• Credit card arbitrage involves borrowing at low rates and investing at higher rates for profit.
• Success depends on making timely payments and settling balances before promotional periods end.
• Arbitrage profits can be significantly reduced by taxes on interest income.
• Missing payments can trigger high interest rates and fees, negating potential profits.
• Market fluctuations and investment fees can challenge reliable profits in credit card arbitrage.

What Is Credit Card Arbitrage?

Credit card arbitrage involves borrowing at a low promotional rate, often through a 0% introductory APR balance transfer, and investing those funds at a higher return. It requires careful on-time payments and awareness of risks such as penalty rates, fees, and possible taxes. A common scenario might yield modest gains if managed well, but missteps can erase profits quickly.

Strategies for Maximizing Credit Card Arbitrage Profits

Credit card arbitrage has a higher likelihood of being successful if a borrower makes all the required minimum monthly payments on the credit card on time and repays the balance in full before the introductory period expires. Even then, though, the amount of money one might earn from this strategy may not be worth the risk.

Borrowers often make less money than they expect when attempting credit card arbitrage. Suppose you borrow $5,000 from your credit card at 0% and invest it in a 12-month CD that pays 2% interest. You would've earned about $100 in interest income at the end of the 12-month term. However, your $100 will be taxed at both the state and federal levels, and the interest income tax is higher than the more favorable capital gains tax rate.1 So, an investor in the 24% federal tax bracket with $100 in CD interest income will be taxed $24 at the federal level, plus whatever the investor’s state tax rate is. In other words, expect to lose up to one-third of your credit card arbitrage earnings to taxes.

Understanding the Risks and Pitfalls of Credit Card Arbitrage

If you borrowed $5,000 from your credit card at a 0% introductory rate but then failed to make the minimum monthly payment on the credit card balance, your arbitrage opportunity is most likely history. If your payment is late, you will likely lose the 0% introductory APR, be charged a $25 late fee, and see the rate on your card skyrocket to 30 percent. That’s about $4 in interest per day on your $5,000 balance, which you’ll have to quickly pay off to end the interest charges. Additionally, if you have to withdraw your CD before maturity, you’ll have to pay a withdrawal penalty of 120 day's interest, which is about $25, Taken together, the late payment, increased credit utilization and new credit line can hurt your credit score, making it harder in the future to get the best rate on a loan like a mortgage.
