When you have questions, we have answersSee full FAQ
We do not run a credit check during the IO application process, so your personal credit score will not be considered or affected.
Your credit limit will be determined by your Mercury account balance. Your limit might increase as your Mercury balance increases, but your credit limit may also decrease. Currently, we reassess your business limit following large withdrawals and deposits.
Mercury primarily makes money from interest earned on customer deposits in Mercury bank accounts. Additionally, when you use your IO credit card or a Mercury debit card, Visa and Mastercard charge a fee to the merchants — we receive a percentage of this fee paid by the merchants, known as interchange. We also earn money on foreign exchange processing on international wires, as well as fees paid on Mercury Treasury* and Mercury Venture Debt.
