Bank of Ireland IT blunder allows customers who have no money get access to cash at ATMs

Hmm. The article doesn't actually say that they'll get an overdraft fee, just that it will be treated as overdrawn. Like, negative balance.

I'm not sure that there will actually be a fee.

While if someone took out exactly as much as they could, I suspect that it's probably pretty fair to say that it was intentional, my guess is that some people probably just went over inadvertently. I doubt that they'd want to hit the inadvertent crowd.

They might charge interest if they give notice and people don't pay it back or something, though. I could believe that.

BANK OF IRELAND has said there will be “no customer detriment in relation to interest” for those who withdrew money from their accounts following a glitch with BOI’s online services.

When asked if customers who withdrew money they didn’t have from their accounts would be subject to interest rates or unauthorised overdraft fees, a BOI spokesperson said: “There will be no customer detriment in relation to interest in that scenario.”
