BBC News - HSBC imposes restrictions on large cash withdrawals
Stephen Cotton went to his local HSBC branch this month to withdraw £7,000 from his instant access savings account to pay back a loan from his mother.
A year before, he had withdrawn a larger sum in cash from HSBC without a problem.
But this time it was different, as he told Money Box: "When we presented them with the withdrawal slip, they declined to give us the money because we could not provide them with a satisfactory explanation for what the money was for. They wanted a letter from the person involved."
Mr Cotton says the staff refused to tell him how much he could have: "So I wrote out a few slips. I said, 'Can I have £5,000?' They said no. I said, 'Can I have £4,000?' They said no. And then I wrote one out for £3,000 and they said, 'OK, we'll give you that.' "
HSBC has said that following customer feedback, it was changing its policy: "We ask our customers about the purpose of large cash withdrawals when they are unusual and out of keeping with the normal running of their account. Since last November, in some instances we may have also asked these customers to show us evidence of what the cash is required for."
