Our policy on unarranged overdrafts & what to do
We do not charge any interest or fees for being in an unarranged overdraft or for payments we reject. However, being in an unarranged overdraft may have a negative impact on your ability to borrow money from Monzo in the future. If you go into an unarranged overdraft, you should add money to your account as soon as possible to bring it back above zero.
